Galvanized GI pipe has one actual12m length/0.5–27mm thickness pair. Schedule40 and3/4inch,2inch,25mm and300mm title requests need a complete nominal-size and wall definition.

Resolve diameter and wall scope

Body OD fields give3–700mm and15–50mm, with2–10mm wall reference. Agree actual geometry instead of treating these as one verified schedule matrix.

• Round section.
• Q235B grade field.
• Galvanized surface.
• Slightly Oiled condition.
• ASTM A53 model.

Verify zinc units and route

The Zinc layer thickness field says0.8–4.0mm or customized. Preserve that stated unit pending actual inspection; do not silently convert it to microns.

Check water-service acceptance

Confirm actual ERW process, BS1387/A53 scope and coating tests. No potable-water approval, pressure rating or corrosion life is established.
