HEX Mechanically Copper-Clad Steel Earth Rods – 250 Micron Copper Tube, 12 to 19 mm Diameter

HEX mechanically copper-clad earth rods are made by fitting an electrolytic-grade copper tube with a 0.25 mm (250 micron) wall over a high-tensile, low-carbon steel rod, using pressure and heat to form a metallurgical bond. The result is a rod with the driving strength of steel and a thick, uniform copper surface. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

At a glance

• Construction: electrolytic copper tube, 0.25 mm wall, bonded to high-tensile low-carbon steel
• Copper thickness: 250 µm
• Rod sizes: 12, 14, 16 and 19 mm
• Lengths: 1200, 1800, 2400 and 3000 mm (4, 6, 8, 10 ft)
• Codes: HCR series
• Options: threaded, or made to customer specification

Why choose copper-clad rods

• Thick, even copper — a 250 µm tube gives a consistent copper layer along the full length.
• Metallurgical bond — pressure and heat bond the tube to the core rather than just sleeving it.
• Steel strength for driving — the high-tensile core resists bending when driven into hard ground.
• Threading on request — for coupled, deep-driven electrodes.

Where it is used

• Building and apartment earthing
• Distribution substations and transformers
• Telecom shelters and towers
• Solar and industrial plant earthing grids

Which earth rod do I need?

• Copper-bonded steel — the everyday choice: steel strength to drive deep, copper surface for low resistance; 25 µm standard, 250–254 µm for long life and UL listing.
• Solid copper — the most corrosion-resistant, for very aggressive or salty soils.
• Copper-clad steel (this page) — a 250 µm copper tube pressed onto a steel core, when a thick, even copper layer is specified.
• Stainless steel — where the rod is buried close to other metals and galvanic corrosion is the concern.

Frequently asked questions

What is a copper-clad earth rod?

A steel rod covered with a copper tube that is bonded to it — HEX uses a 0.25 mm electrolytic copper tube fitted by pressure and heat to form a metallurgical bond.

How is it different from a copper-bonded rod?

Copper-bonded rods have copper deposited onto the steel; clad rods have a formed copper tube pressed onto it. Both combine a steel core with a copper surface.

Which sizes are available?

12, 14, 16 and 19 mm rods in 1200 to 3000 mm lengths, codes HCR-1412 to HCR-430.

Can the rods be threaded?

Yes — threading and other sizes can be supplied to customer specification.
