Mild Steel ERW Pipes/Tubes
Rectangular Hollow Section
Product Summary
Mild Steel ERW Rectangular Hollow Sections are manufactured using the Electric Resistance Welding (ERW) process, offering excellent strength, durability, and dimensional accuracy. These steel sections are known for their high load-bearing capacity, smooth finish, and resistance to bending, making them a reliable choice for structural and fabrication applications. Their rectangular shape provides enhanced support and flexibility in design, making them suitable for various industrial and construction needs.
