Complete lightning protection systems, designed to the level your risk assessment demands

The Aluminium Earthing Strip (ARK-ALSTP) is an ARK earthing and lightning protection component manufactured by DFMHUB in India. It provides a lightweight conductive path where the earthing design and installation environment specifically permit aluminium. It is intended for engineered systems in commercial buildings, industries, data centres, high-rise developments, infrastructure and solar projects. The catalogue code gives procurement, consultants and site teams a controlled item to coordinate with the BOQ, approved drawings and inspection plan. Earthing conductors carry fault, bonding and sometimes lightning current between equipment, structures and electrodes. The required cross-section must come from the engineered duty, disconnection time, thermal limits, mechanical protection and applicable standard. Product size alone cannot guarantee a target earth resistance because resistance is a result of the complete electrode system and local soil conditions. Long-term reliability depends on the conductor material, corrosion protection, bends, supports and joints. Buried, concrete-embedded and exposed routes present different risks. The approved submittal should define grade or alloy, dimensions, coating where applicable, supply length, joint method, contact with other metals and the inspection records required before concealment. DFMHUB supplies ARK as a manufacturer-led product range rather than an assortment of unrelated trading items. Drawings, material selection, fabrication or assembly, dimensional inspection, packing and order-specific documentation can be coordinated before dispatch. The final technical submittal should state the exact grade, dimensions, finish, tolerances, connection details and test evidence agreed for the selected configuration. This approach builds traceability without replacing project engineering with broad marketing claims.

The Copper Earthing Strip (ARK-CU) is an ARK earthing and lightning protection component manufactured by DFMHUB in India. It provides a low-resistance metallic path between designed earth electrodes, bonding bars, equipment and structural interfaces. It is intended for engineered systems in commercial buildings, industries, data centres, high-rise developments, infrastructure and solar projects. The catalogue code gives procurement, consultants and site teams a controlled item to coordinate with the BOQ, approved drawings and inspection plan.

The 10-16mm Tapered Air Terminal Rod with Base (ARK-AT16) is an ARK lightning protection component manufactured by DFMHUB in India. It provides a raised strike-reception point at the position defined by the engineered lightning protection layout. It is intended for engineered systems in commercial buildings, industries, data centres, high-rise developments, infrastructure and solar projects. The catalogue code gives procurement, consultants and site teams a controlled item to coordinate with the BOQ, approved drawings and inspection plan. An air terminal is one part of a complete external lightning protection system. Its safe performance depends on the risk assessment, selected Lightning Protection Level, protection method, conductor routes, separation distance, earth termination and inspection plan. The number or shape of strike points does not replace engineering by the protection-angle, rolling-sphere or mesh method where applicable. The terminal and support must withstand wind, vibration and site handling while maintaining a dependable electrical path. Material compatibility matters at the rod, connector, base and roof interface. Product approval should therefore cover dimensions, material grade, corrosion protection, connection method, mechanical support and relevant test evidence for the exact supplied configuration. DFMHUB supplies ARK as a manufacturer-led product range rather than an assortment of unrelated trading items. Drawings, material selection, fabrication or assembly, dimensional inspection, packing and order-specific documentation can be coordinated before dispatch.

ARK-ST01 is a stainless steel strip holder clamp designed to support flat conductor strips used in lightning protection, bonding and associated earthing interfaces. Flat strips require different support geometry from round conductors, and a purpose-made holder helps keep the strip aligned without uncontrolled twisting, sagging or site-made strapping. ARK-ST01 is suitable for vertical or horizontal routes on walls, columns and approved structural surfaces where a flat conductor forms part of the engineered electrical safety system. Selection should start with the strip width, strip thickness and conductor material. The holder should retain the conductor securely without forcing sharp deformation, and the fixing hardware should suit the mounting substrate. Where the strip is routed outdoors, environmental exposure, water paths and corrosion compatibility should be reviewed. Dissimilar-metal interfaces are particularly important when stainless steel holders are used with copper, aluminium or galvanized strips. The route should remain accessible for inspection where required and should be coordinated with architectural finishes, mechanical services, movement joints and other construction details. ARK-ST01 forms part of the ARK External Lightning Protection System by DFMHUB and can be incorporated into projects where flat strip conductors are specified for down-conductor, bonding or transition routes. Standardized holders help EPC contractors maintain consistent workmanship and make it easier for consultants to inspect the conductor path. They also improve BOQ clarity because the support component is defined rather than left as an unspecified “suitable clamp.” IEC 62561-4 provides the relevant standard context for conductor fasteners used to retain and support LPS conductors. The wider external lightning protection system should be engineered with reference to IEC 62305-3 and the project specification. Before approval, confirm strip dimensions, holder material, fixing arrangement, corrosion environment and the applicable ARK technical documentation. If the strip is part of an earthing or bonding interface outside the external LPS scope, the project’s earthing and electrical standards should also be reviewed so the mechanical holder is used within the correct system design. Engineering confidence: DFMHUB supports Stainless Steel Strip Holder Clamp (ARK-ST01) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

ARK-RD01 is a stainless steel down conductor holder clamp used to retain a lightning protection down conductor along walls, columns and other vertical building surfaces. Down conductors form the controlled path between the roof-level air-termination system and the earth-termination arrangement, so their routing and physical support must remain consistent with the engineered LPS design. ARK-RD01 provides a durable, identifiable fixing point for exposed vertical conductor runs and helps keep the route straight, accessible and visually organized. The holder should be selected according to conductor diameter, wall or facade substrate, anchor type, stand-off requirement and environmental exposure. On concrete or masonry, fixing hardware must be appropriate for the substrate. On facades, the route should be coordinated with cladding joints, windows, services and architectural finishes. The conductor should also be protected from accidental impact where it passes through accessible areas. Where stainless steel comes into contact with aluminium, copper or galvanized materials, the approved interface should be checked for galvanic compatibility, especially in humid, coastal or chemically aggressive locations. ARK-RD01 is part of the ARK External Lightning Protection System by DFMHUB and can be specified with compatible ARK conductors, test joints and connection components. For contractors, a standard holder improves fixing consistency over long vertical runs. For consultants and facility teams, it creates a cleaner inspection route because each down conductor can be visually followed from roof level toward the test-joint or earth-termination area. It also provides better traceability in BOQs and maintenance records than unbranded or site-fabricated supports. IEC 62561-4 is the relevant component-standard context for conductor fasteners used to retain and support down-conductor systems. IEC 62305-3 provides the broader requirements for down-conductor arrangement, installation, inspection and maintenance. Before final approval, verify the actual conductor size, fixing details, stainless steel grade or declared material, anchor requirements and applicable ARK test documentation. Installation spacing and routing should always follow the approved LPS drawing and project method statement. Engineering confidence: DFMHUB supports Stainless Steel Down Conductor Holder Clamp (ARK-RD01) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

ARK-QC10 is the ARK Vario Quick Connector Clamp, also identified in the product range as an MV Clamp. It is a versatile connection component used where lightning protection conductors need to be joined at a crossing, branch or compatible interface. Roof conductor networks often contain multiple junctions, and a compact adjustable clamp can simplify installation when the conductor arrangement is within the approved size and geometry range. ARK-QC10 gives contractors a standardized alternative to site-made connections and helps maintain a consistent appearance across the external LPS. The clamp should be selected based on the actual conductor diameter, conductor shape, crossing angle and material combination. Although the term “Vario” or “MV” can suggest flexibility, it should not be treated as universally suitable for every conductor. Each connection needs to match the ARK technical data and the project drawing. Correct tightening is important because a lightning protection connection must remain mechanically stable and electrically continuous under normal service conditions. Where the clamp is exposed to rain, industrial pollution or coastal conditions, material compatibility and corrosion performance should also be reviewed. ARK-QC10 is part of the ARK External Lightning Protection System by DFMHUB and can be used with compatible ARK round conductors and related fixing components. For EPC contractors and consultants, using a recognizable part code at conductor junctions makes BOQs, material inspections and as-built documentation clearer. It also reduces dependence on multiple clamp types where a single approved connection component can satisfy the specified conductor arrangement. IEC 62561-1 is the relevant component-standard context for metallic connection components used within lightning protection systems. IEC 62305-3 provides the wider design and installation framework. Before approval, verify conductor compatibility, material pairing, permitted connection arrangement, hardware, tightening requirements and applicable ARK test reports. The installer should follow the approved LPS layout and project method statement, and completed joints should be visually inspected so that loose hardware, incorrect conductor seating or unsuitable material combinations are identified before handover. Engineering confidence: DFMHUB supports Vario Quick Connector Clamp / MV Clamp (ARK-QC10) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

ARK-SL01 is a straight connector designed to join compatible 8-10 mm round conductors in an external lightning protection system. Straight joints are commonly required where conductor lengths need to be extended, where installation routes are divided for handling or where a defined in-line connection is needed on a roof or down-conductor path. Using a purpose-made connector helps create a repeatable mechanical and electrical joint instead of relying on overlapping conductors, uncontrolled fabrication or non-LPS hardware. Correct connector selection starts with the actual conductor diameter and material. The joined conductors should sit correctly within the connector and remain aligned so the LPS current path is not dependent on a loose or poorly fitted joint. Tightening should follow the applicable ARK installation data or project method statement. On exposed roofs and facades, the connection should also be evaluated for corrosion, water exposure and compatibility between conductor and connector materials. The final joint should remain accessible for inspection where the LPS maintenance plan requires visual or mechanical checks. ARK-SL01 is part of the ARK External Lightning Protection System by DFMHUB and can be combined with ARK round conductors, cross connectors, roof holders and down-conductor fixing components. This makes it easier for consultants and EPC teams to specify a consistent component set rather than sourcing unrelated connectors with uncertain fit. On large projects, standardized straight connectors can also improve installation speed and reduce variability between different work crews. IEC 62561-1 is the relevant component-standard context for metallic connection components used in lightning protection systems, including connectors and clamps. IEC 62305-3 provides the wider framework for the external LPS. Before approval, confirm the actual conductor diameter range, material pairing, connector construction, tightening requirement and applicable ARK test documentation. The connection should be installed in accordance with the approved LPS drawings, and any consultant requirement for inspection, torque verification or corrosion protection should be incorporated into the method statement. Engineering confidence: DFMHUB supports Straight Connector for Rd 8-10 mm Round Conductor (ARK-SL01) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

Cross connector ARK-CRS08 designed for compatible 8-10 mm round conductors used in external lightning protection systems. Cross connectors are commonly required where roof conductors intersect in an air-termination mesh, where a branch joins a perimeter conductor or where two round conductors must be mechanically and electrically connected at a crossing. A dedicated cross connector keeps the conductors positioned at the intended intersection and creates a repeatable joint that can be inspected during installation and maintenance. The connection must be selected based on the actual conductor diameter, conductor material and crossing arrangement. Conductors should sit correctly within the clamp, and hardware should be tightened according to the ARK technical data or approved method statement. Because the connector is stainless steel, the project team should review the contact interface when it is used with aluminium, copper or coated conductors. Material compatibility is especially important on exposed roofs, coastal locations and industrial sites where moisture or pollutants can accelerate corrosion. The connection point should remain free from unnecessary mechanical stress caused by poorly aligned conductor routes. ARK-CRS08 is part of the ARK External Lightning Protection System by DFMHUB and can be specified alongside ARK 8 mm aluminium conductor, roof holders, parapet clamps and straight connectors. This creates a more coherent roof network and gives consultants a clearly identified component at conductor intersections. For installers, standardized cross connectors reduce the need for improvised overlaps and can improve consistency across large mesh systems. IEC 62561-1 is the relevant component-standard context for metallic LPS connection components such as clamps and connectors. IEC 62305-3 provides the wider requirements for the external lightning protection system. Before approval, verify the actual conductor range, stainless steel grade or declared material, bolt arrangement, tightening requirement, material pairing and applicable ARK test evidence. The final connection layout must follow the approved LPS drawing, because the connector itself does not determine mesh size, protection class or conductor routing. Engineering confidence: DFMHUB supports Stainless Steel Cross Connector for Rd 8-10 mm (ARK-CRS08) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

Roof Conductor Holder Clamp (ARK-SS03)designed to secure a lightning protection conductor along an approved roof-level route. In a conventional external LPS, the roof conductor may form part of an air-termination mesh, perimeter ring, branch connection or route linking air terminals to down conductors. The holder provides a defined fixing point so the conductor remains positioned as designed and does not shift due to weather, maintenance activity or normal movement on the roof. The product is suitable for projects where the roof construction and conductor arrangement are compatible with the clamp design. Before selection, the installer should confirm the conductor diameter, mounting surface, fixing method, roof finish and environmental exposure. The route must be coordinated with drainage, waterproofing, roof joints, access areas and mechanical or solar equipment. Where dissimilar metals are present, the complete material interface should be reviewed to control corrosion. The clamp should not be used as a substitute for engineering decisions such as conductor spacing, air-terminal positioning or separation distance; those are defined by the LPS design. As part of the ARK External Lightning Protection System by DFMHUB, ARK-SS03 can be coordinated with ARK round conductors, straight connectors, cross connectors and other fastening components. This gives contractors a consistent product family and gives consultants a clearer basis for material approval and inspection. Using identified LPS components also improves traceability in project BOQs and handover records, particularly on larger industrial and infrastructure projects where many roof routes are installed. DFMHUB supports Roof Conductor Holder Clamp (ARK-SS03) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

ARK-SS02 is a metal roof holder clampdeveloped to support lightning protection conductors on metal roofing systems where a secure and coordinated fixing point is required. Metal roofs are common across industrial sheds, warehouses, factories, logistics buildings, commercial structures and solar facilities, but roof profiles and materials can vary significantly. A purpose-made conductor holder allows the LPS route to be installed in a controlled manner while reducing dependence on improvised drilling, strapping or general-purpose hardware. The clamp should be selected based on the actual roof profile, sheet material, conductor diameter, fixing orientation and exposure conditions. On metal-roof projects, the installation team must also consider corrosion compatibility between the holder, conductor and roof finish. The lightning protection route should remain coordinated with roof joints, flashings, skylights, access paths, solar modules and other equipment. Where the roof manufacturer restricts penetrations or specific fastening methods, those requirements should be reviewed before installation. The LPS designer should determine the conductor layout; the holder’s role is to retain the conductor in the intended position. ARK-SS02 is supplied as part of the ARK External Lightning Protection System by DFMHUB and can be used with compatible ARK conductors and connectors. This system-based approach helps EPC contractors and consultants maintain consistency in product selection, BOQ descriptions, material inspections and handover documentation. It also makes replacement and future maintenance easier because the component can be identified by part code rather than as an unspecified site clamp. DFMHUB supports Metal Roof Holder Clamp (ARK-SS02) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

Standing seam roof conductor holder clamp, ARK-SS01 designed for routing external lightning protection conductors on standing seam metal roofing. Standing seam roofs need a fixing method that respects the roof profile and avoids unnecessary penetration of the weathering surface. ARK-SS01 provides a defined attachment point at the seam so the conductor can follow the engineered roof-level LPS route without relying on improvised drilling or unsuitable general-purpose clamps. This product is suited to PEB buildings, factories, warehouses, airports, commercial roofs, industrial sheds and other structures using standing seam roof systems. The clamp should be selected with reference to the actual seam geometry, roof sheet material, conductor size and the approved lightning protection layout. Because standing seam profiles vary between roof manufacturers, project teams should confirm mechanical compatibility before installation. Conductor routing also needs to be coordinated with roof expansion, maintenance walkways, ridge details, solar modules and other rooftop equipment. Material compatibility is important wherever stainless steel, aluminium, coated steel or other metals come into contact. Within the ARK External Lightning Protection System by DFMHUB, ARK-SS01 can be paired with suitable round conductors and ARK connection components to create a consistent roof network. A dedicated standing seam clamp gives contractors a repeatable fixing method and helps consultants visually verify that the LPS conductor has been installed along the approved path. It can also reduce the risk of site teams modifying the roof in ways that may affect the roofing warranty or water-tightness. DFMHUB supports Standing Seam Roof Conductor Holder Clamp (ARK-SS01) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.

ARK-FL08 Flat roof conductor holderintended to support a round lightning protection conductor on RCC roofs, terraces and other flat-roof surfaces. External lightning protection systems often require conductors to follow a defined roof mesh, perimeter route or connection path between air terminals and down conductors. The holder keeps that route controlled and helps prevent the conductor from moving out of position due to wind, maintenance activity or normal site conditions. It is a practical component for projects where a neat, repeatable and inspectable roof-level LPS installation is required. ARK-FL08 is part of the ARK External Lightning Protection System by DFMHUB. It can be integrated with ARK round conductors, connectors and other roof or parapet fastening components to create a consistent system across the project. For consultants and EPC teams, using identifiable components with part codes also improves BOQ clarity, material inspection and handover documentation compared with mixed or improvised supports sourced at site. IEC 62561-4 is the relevant component-standard context for conductor fasteners used to retain and support lightning protection conductors, while IEC 62305-3 provides the wider framework for the design and installation of the external LPS. Final selection should be based on the current ARK technical datasheet, conductor compatibility, fixing method, environmental exposure and the consultant-approved project specification. Where test evidence is required, the exact supplied component and relevant test report should be reviewed rather than relying on a general compliance statement.

Nylon Parapet Conductor Clamp /Parapet Holder Clamp (ARK-PH08) is an ARK external lightning protection component manufactured by DFMHUB in India. It retains a round lightning conductor along parapet surfaces while keeping the route orderly and accessible for inspection. The product is intended for engineered lightning protection installations on commercial, industrial, residential, infrastructure, data-centre and solar projects. It gives procurement and site teams a defined catalogue item instead of an improvised site-made part. A conductor fastener is a safety-relevant part of the installed system because poor restraint can change conductor routing, stress a joint or make inspection difficult. The holder must match the conductor, roof or wall interface and exposure conditions. The fixing to the building fabric must also be engineered for the actual substrate; component compliance alone does not validate an unsuitable anchor or roof detail. DFMHUB supports the ARK range as a manufacturer, with controlled drawings, repeatable fabrication or assembly, dimensional checks and project-specific technical coordination. Material grade, dimensions, finish, fastener configuration and any required test evidence should be frozen in the approved technical submittal before production. This approach helps consultants, EPC teams and contractors compare the offered component with the BOQ, installation detail and environmental exposure rather than relying only on a product name. Technical Specifications • Neat support for exposed parapet routes • Non-metallic body helps separate conductor from the mounting surface • Simple inspection of conductor seating • Repeatable mounting across long roof perimeters During installation, keep the conductor seated without damaging its surface, maintain the route shown on the approved drawing and use the specified anchors and torque. Coordinate penetrations with waterproofing requirements. The completed route should remain visible and accessible for periodic inspection, especially after roof work or severe weather. Selection note: Verify conductor diameter, parapet material, anchor type, exposure conditions, fixing interval and movement allowance before installation. The applicable system layout should be prepared by a competent lightning protection designer and coordinated with the structure, roof system, services and earthing network. For quotations, submit the product code ARK-PH08, required quantity, conductor or interface dimensions, material preference, project location and approved drawing. DFMHUB can then align manufacture, inspection records, packing and delivery with the project requirement.

ARK-AL08 is an 8 mm aluminium solid round conductorA developed for use in conventional external lightning protection systems. The conductor can be used as part of an engineered air-termination network, roof conductor route or down-conductor arrangement where aluminium has been selected by the project designer. Its round profile is practical for routing across roofs, parapets and facades and allows the conductor to be secured with compatible ARK holders, clamps and connectors. For industrial plants, data centres, commercial buildings, warehouses, solar projects and infrastructure, the conductor gives contractors a clearly defined LPS component that can be incorporated into drawings, BOQs and technical submittals. Selection of an LPS conductor should never be based on diameter alone. The overall lightning protection design must consider the required lightning protection class, air-termination layout, down-conductor routing, separation distance, bonding and earth-termination arrangement. On site, conductor bends should be smooth and routing should remain coordinated with roof membranes, expansion joints, access paths and rooftop equipment. Where aluminium is used near copper, galvanized steel or other dissimilar metals, the connection arrangement should be checked for material compatibility and corrosion risk. Compatible connectors and holders should be selected instead of improvised site joints. ARK-AL08 is positioned as part of the ARK External Lightning Protection System by DFMHUB, allowing project teams to source the conductor together with roof holders, parapet clamps, straight connectors, cross connectors, test joints and down-conductor fixing components. This helps maintain consistency across the complete LPS installation and simplifies procurement and inspection. For technical specifications, IEC 62561-2 is the relevant component-standard context for metallic conductors used in lightning protection systems, while IEC 62305-3 provides the wider design and installation framework for the external LPS. Final material grade, tolerances, test evidence and project-specific acceptance should be verified against the current ARK technical datasheet and approved consultant specification before installation. Engineering confidence: DFMHUB supports 8 mm Aluminium Solid Round Conductor (ARK-AL08) with product identification, dimensional review, material/finish confirmation and order-specific documentation as agreed in the quotation or approved submittal. The component must be selected as part of the complete engineered system, not by product code alone.
