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.
