Define actual square section and production evidence before requesting mechanical carbon steel tubing.
Route and standard
The title combines ASTM A513 and seamless wording while the detail provides no verified production route. Confirm the applicable standard, actual manufacture and grade rather than treating title references as established compliance.
Side and wall
The detail identifies square shape with a0.4–16 mm or required thickness scope but no outside sides. Provide a complete section drawing, select compatible wall and finished length, and agree dimensional tolerance and the non-oiled delivered surface.
- Actual grade and tube route
- Applicable material standard
- Outside square sides and wall
- Length and non-oiled surface
- Mechanical or structural tests
Design acceptance
Fluid and structural applications are broad labels without actual ratings. Request material and project inspection records; the listing establishes no pressure capability, load capacity or certified suitability for every mechanical installation.
