  Sample Freely

Provide the outside section and actual material designation when requesting square carbon steel tube.

Material and route

The title lists several steel grades, ERW and hot dip galvanizing without a complete supplied section specification. Select one actual designation and confirm the welding route and delivered coating rather than treating all title references as verified alternatives.

Square geometry

The detail identifies a square shape and a 0.4–16 mm or required thickness scope. Outside side dimensions are not provided, so agree the actual sides, compatible wall and finished length with a section drawing.

• Actual steel designation
• Outside square sides
• Compatible wall and tolerance
• Length and welded condition
• Galvanizing and material inspection

Project acceptance

Fluid and structural applications appear as broad labels. Request the actual material standard and project tests; these references establish neither pressure capability nor structural capacity, certified compliance or equivalence among the named grades.
