Square Hollow Carbon Steel Tube | ASTM Specification, Custom Length and Bending Cutting Service
Square hollow steel tube is described with 0.4–16mm or required wall thickness and 6m, 6.4m, 12m or customized length. The source identifies non-alloy carbon steel, non-oiled surface and a hot rolled description.
No actual size options or outside side dimensions are supplied. Provide width, height, wall and finished length together, then identify the required substrate grade and ASTM hollow-section specification. The broad carbon steel designation is not a complete material acceptance requirement.
For fabrication, state the bend geometry and cut tolerance on a drawing. Oil, hydraulic and boiler pipe application labels do not qualify a square section for pressure service. Obtain the relevant material and dimensional documents; processing services alone do not establish structural capacity or suitability for every named use.
