Overview

Heavy gauge steel pipes are designed for applications that require greater strength, durability, and load-bearing capacity.

These pipes are manufactured using Electric Resistance Welding (ERW) and are available in both Black Iron (BI) and Galvanized Iron (GI) finishes.

They are commonly used in:

Structural construction
Industrial systems
Water distribution
Fire protection
