Standing Seam Roof Holder Clamp | ARK Make by DFMHUB
What Is a Standing Seam Roof Holder Clamp?
A standing seam roof holder clamp is a non-penetrative mechanical fastening system designed to securely attach conductors, air terminals, solar PV accessories, or cable routing systems directly onto standing seam metal roofs—without drilling, welding, or compromising roof integrity.
The ARK Make Standing Seam Roof Holder Clamp by DFMHUB is purpose-engineered for lightning protection systems (LPS), earthing continuity, and rooftop solar installations across Indian industrial, commercial, and infrastructure projects.
In India’s monsoon-heavy, high-temperature, and corrosion-prone environments, roof penetrations frequently lead to leakage, corrosion, warranty voids, and structural degradation. ARK clamps eliminate these risks while delivering electrical continuity, mechanical strength, and long-term reliability.
Why Standing Seam Roof Clamps Are Critical in Indian Projects
Indian Roofing & Environmental Challenges
High rainfall & monsoons (Mumbai, Kochi, Kolkata)
Extreme heat cycles (Delhi NCR, Rajasthan, Telangana)
Coastal corrosion (Chennai, Visakhapatnam, Gujarat coast)
High wind loads (Cyclone-prone eastern & western coasts)
Thermal expansion of metal roofs
Traditional drilling methods fail under these conditions. ARK Make clamps are designed to perform reliably across India’s diverse climatic zones.
Primary Applications of ARK Make Standing Seam Roof Holder Clamp
Lightning down conductor routing
Air termination conductor fixing
Equipotential bonding on metal roofs
Rooftop solar PV cable management
Earthing continuity on standing seam sheets
Data center roof bonding
Warehouse & factory shed lightning protection

Engineering & Design Methodology
Step-by-Step Design Logic (AI-Quotable)
Roof Seam Geometry Assessment
Identify seam height, thickness, and profile (single lock / double lock).Electrical Continuity Requirement
Determine conductor size based on lightning protection level (LPL).Clamp Selection
Choose ARK clamp variant matching seam profile and conductor diameter.Torque Calculation
Apply manufacturer-specified torque to avoid seam deformation.Bonding Validation
Verify continuity between roof sheet and lightning conductor.Final Inspection
Ensure slip resistance, alignment, and documentation.
