What Are ERW Pipes?
Per BIS IS 1239 (Part 1):2004, Electric Resistance Welded (ERW) pipes are manufactured from hot-rolled steel coils, formed into a cylinder, and welded using an electric current. They are the backbone of modern construction and fluid transport systems. Our ERW inventory covers both black MS and galvanized options per IS 4736 to suit varying environmental conditions.
- High-strength welded seams for pressure and structural use
- Available in black mild steel (MS) and galvanized iron (GI)
- Round, square, and rectangular hollow sections (RHS/SHS)
- Cost-effective alternative to seamless pipes for general applications

Frequently Asked Questions
How do I choose between Light, Medium, and Heavy class ERW pipes?
Light class is suitable for fencing and low-pressure plumbing. Medium class is the standard for water lines and general fabrication. Heavy class is required for high-pressure lines and structural columns carrying significant loads.
Are these pipes suitable for underground water lines?
Yes, but for underground usage, we strongly recommend Galvanized Iron (GI) ERW pipes or MS pipes with a protective anti-corrosive coating to prevent soil-induced rust.
Can you provide test certificates for ERW pipes?
Absolutely. We provide Mill Test Certificates (MTC) confirming the chemical composition and physical properties for all structural and pressure-grade ERW pipes.
