Trusted experts in Earthing and Lightning Protection Systems since 2005.
Earthing Accessories Chennai — ARK Make by DFMHUB specializes in corrosion-resistant grounding hardware for Chennai’s coastal, saline-prone environments. Our product range (tinned copper clamps, FRP inspection chambers, bimetallic connectors) is engineered to combat chloride-induced corrosion and maintain low earth resistance across life cycles—designed for IS 3043 and IEC compliance.
Typical concerns: coastal salinity, high humidity, and monsoon-driven waterlogging in low-lying zones. Chloride presence accelerates corrosion in exposed joints.
Key impacts: need for tinned finishes, FRP/Polymer pits, sealed joints, and a strong maintenance/testing program.

| Compliance | Failure during IS 3043 audits |
Low Contact Resistance across joints
Material Compatibility with copper, GI, aluminum systems
Mechanical Strength under fault current stress
Long-term Corrosion Protection
Ease of Inspection & Testing
| Component | Material Options | Application |
|---|---|---|
| Rod to Strip Clamp | Gunmetal / Phosphor Bronze | Electrode to strip connection |
| Strip to Strip Clamp | Copper / GI | Grid interconnections |
| Strip to Cable Clamp | Bimetallic | Copper-Aluminum transition |
| Parallel Cable Clamp | Tinned Copper | Power & control grounding |
Engineering Advantage:
Precision-machined contact surfaces ensure stable micro-ohm resistance even after years underground.
