Mild Steel ERW Pipes/Tubes
Square Hollow Section
Product Summary
Mild Steel ERW Square Hollow Sections are high-strength steel tubes manufactured using the Electric Resistance Welding (ERW) process. Designed for durability, precision, and excellent load-bearing capacity, these hollow sections offer superior structural stability and a smooth surface finish. They are widely used in construction and industrial applications due to their strength, versatility, and cost-effectiveness.
