2.5 Inch Galvanized Hollow Square and Rectangular Tube Requests | 6m 6.4m 12m Lengths
Galvanized ERW square tube is listed with a 0.5–6.0mm wall selector and actual lengths of 6m, 6.4m and 12m. The body instead describes 2–10mm wall, with small square section examples of 10×10, 15×15 and 20×20mm.
The title requests a 2.5 inch section and also names rectangular pipe; confirm outside dimensions and shape on a drawing. The descriptive 5.8–12m length range does not replace the actual length selection. Zinc layer thickness is recorded as 2.5–15μm or customized and needs an agreed acceptance requirement.
For fabrication, identify the substrate grade, cut length and any bending details. A general ASTM entry and certificate list do not establish every configuration as a certified pressure pipe. Select a feasible wall and section combination and obtain the relevant dimensional and material inspection documents.
