Galvanized round steel pipe has one actual thickness-range option: 0.5–27mm. The 40mm diameter and ASTM A500 Gr.B title requirements need actual material and size confirmation.

Agree OD and wall together

Family references include OD3–700mm, diameter15–50mm and wall2–10mm. These are independent ranges, not a complete actual size matrix.

• Q235B grade field.
• Round pipe/tube identity.
• Slightly oiled description.
• 6m and12m reference lengths.
• Cold-drawn/hot-rolled alternatives.

Clarify zinc measurement

The zinc-layer thickness is written 0.8–4.0mm or customized. Preserve that original unit and request the actual coating measurement basis rather than silently converting it or assuming a verified result.

Set service requirements

Oil, boiler and structural contexts do not establish operating ratings. Request actual grade, wall, coating and application inspection records before engineering use.
