Standard GI Pipe 1 1/2 Inch Galvanized Steel DN40

GI Pipe 1 1/2 Inch

The Standard GI Pipe 1 1/2 inch is a high-durability plumbing and structural component manufactured from carbon steel. Each length undergoes a hot-dip galvanization process to provide a thick zinc coating for maximum corrosion resistance. This DN40 pipe serves critical functions in pressurized water distribution and heavy-duty outdoor frameworks.

Built for the Job

Plumbers and site supervisors prioritize galvanized piping for its superior mechanical strength compared to synthetic alternatives. The 1.5-inch nominal diameter offers a high flow rate for main supply lines in both residential and industrial settings. This steel conduit withstands high-pressure environments and significant physical impact without deformation. The zinc layer acts as a sacrificial barrier, protecting the inner steel from oxidation when buried or exposed to the elements. Contractors frequently select this material for structural fabrication, including security fencing, gate frames, and temporary scaffolding. Its rigidity ensures long spans remain straight under load. The internal bore remains smooth to minimize friction loss during fluid transport. This specific gauge handles temperatures and pressures that exceed the limits of standard PVC or PPR systems.

• Installation of main water supply lines for commercial and residential buildings.

• Fabrication of heavy-duty handrails, guardrails, and security perimeter fencing.

• Construction of structural frameworks for agricultural greenhouses and outdoor sheds.

Product Highlights

The hot-dip process ensures a uniform protective layer that prevents rust even in high-moisture zones.

Structural Integrity

• High-tensile carbon steel core for load-bearing applications
• Resistant to crushing and external mechanical damage on site

Technical Specifications

What’s Included

• 1 x 6-Meter Length of 1 1/2 Inch Galvanized Steel Pipe

On-Site & Workshop Notes

• Use a heavy-duty pipe threader with sharp dies to ensure clean connections for threaded fittings.

• Apply industrial-grade thread sealant or PTFE tape to all joints to prevent leaks in pressurized systems.

• Protect any cut ends with cold galvanizing spray to restore the protective zinc barrier immediately.

• Store these steel lengths on flat, raised racks to prevent ground moisture contact and bowing.
