🔍 What Are GI Round and Square Pipes?

✅ GI Round Pipe

• Circular cross-section

• Used for plumbing, scaffolding, water lines

• Easier to bend, thread, and flow liquids

✅ GI Square Pipe

• Square hollow section (SHS)

• Used for fabrication, railings, and structural frameworks

• Provides even load distribution in box designs

Both pipe types are made from mild steel (MS) and undergo hot-dip galvanization, forming a zinc-coated outer layer that protects against rust and corrosion.
