Materials for safe, low-resistance earthing systems and lightning protection, sourced by material, dimension and system design.
Earthing gives fault current a safe path to ground so protective devices operate and exposed metalwork stays at a safe voltage. Lightning protection captures strikes and conducts them safely to earth.
Earthing design is site-specific: soil resistivity, fault level and the target earth resistance decide how many electrodes are needed and how they are arranged. Standards such as IEC 62305 (lightning protection) and BS 7430 (earthing) are commonly referenced in specifications.
Each line below explains what it is, where it is used, and what to include in your enquiry so we can quote accurately.
Earth rods are driven into the ground as electrodes. Copper-bonded steel rods combine strength for driving with copper’s corrosion resistance; solid copper and stainless rods are also used.
Buying noteState quantity, diameter, length and whether couplers for extension are needed.
Clamps connect conductors to rods, tapes and structures. Joints are the weak points in an earthing system, so clamp material should be compatible with the rod and conductor.
Buying noteMatch clamps to rod diameter and conductor size.
In general usage the term covers both air terminals that intercept strikes on buildings and surge arresters that protect electrical equipment from overvoltage.
Surge arresters for distribution lines and transformers are rated by system voltage and discharge current; surge protective devices (SPDs) protect LV boards.
Buying noteClarify which type is needed and the system voltage it protects.
Earth pits house the electrode connection for inspection and testing. Inspection covers protect the pit; earth enhancement compounds lower resistance in high-resistivity soil.
Buying noteSend the earthing design or required number of pits and electrode details.
Bare copper tape forms earth grids, down conductors and bonding conductors. It is specified by width × thickness, such as 25×3 mm, and supplied in coils.
Buying noteGive size and total length; include fixings such as tape clips if needed.

Quick answers about sourcing earthing.
It depends on the system and specification. Your designer or client standard sets the target.
Copper-bonded rods drive more easily; solid copper may be specified for corrosive soils. Follow your specification.
