Trade Standard 1 1/4 Inch GI Pipe, 40mm Nominal Bore, 6m Length

GI Pipe 1 1/4 Inch (40mm)

The Trade Standard GI Pipe provides a robust solution for pressurized fluid transport and structural framing in industrial and residential environments. This 40mm nominal bore piping features a hot-dip galvanized coating to prevent oxidation in high-moisture areas. It meets standard site requirements for water distribution, gas lines, and mechanical protection of electrical conduits.

Built for the Job

Contractors specify this 1 1/4 inch galvanized steel tubing for its high tensile strength and resistance to mechanical impact. On the job site, this material handles the stresses of high-pressure water systems and structural loads in scaffolding or fencing. The zinc coating ensures that the steel core remains protected even when buried or exposed to the elements for extended periods.

• Installation of main water supply lines in commercial plumbing.

• Fabrication of heavy-duty gate frames, handrails, and security barriers.

• Deployment in irrigation systems requiring rigid, corrosion-resistant pipework.

Product Highlights

Corrosion Resistance

Each length undergoes a hot-dip galvanization process to provide a thick zinc layer that prevents rust and scale buildup.

Structural Integrity

• Manufactured from high-grade carbon steel for superior pressure ratings.
• Uniform wall thickness ensures consistent performance during threading and bending.

Technical Specifications

What’s Included

• 1 x 6-Meter Length of 40mm Galvanized Iron Pipe

On-Site & Workshop Notes

• Ensure all cut ends are deburred and treated with cold-galvanizing spray to prevent localized oxidation at the joint.

• Use heavy-duty pipe wrenches for assembly to avoid slipping on the smooth galvanized surface.

• Verify compatibility with existing fittings by checking thread pitch (BSPT is standard for this size).

• Store horizontally on flat racks to prevent bowing or warping over long durations in the yard.
