Galvanized round pipe has two actual pairings of0.5–27mm wall range with6m or12m length. Seamless title wording requires actual manufacturing-route confirmation.

Choose OD and wall

Family references include OD3–700mm, diameter15–50mm and wall2–10mm. Select the actual OD/wall pair rather than treating independent ranges as a supplied-size matrix.

• Q235B grade field.
• Round Pipe Tube shape.
• Slightly oiled description.
• Cold-drawn/hot-rolled alternatives.
• Cutting and bending services.

Clarify coating measurement

Zinc-layer thickness is written0.8–4.0mm or customized. Keep that original unit and request its actual measurement basis rather than converting it or claiming a verified result.

Agree gas/oil inspection

Specify actual grade, process and service tests. Gas, oil and boiler contexts do not establish operating pressure, temperature or approved installation performance without selected-pipe evidence.
