Carbon Steel Square Rectangular Tube, 0.4–16 mm Wall for Building Frames
Carbon steel hollow tube is described with wall thickness 0.4–16 mm or required specification. Length references include 6, 6.4 and 12 m, with customized 6–12 m supply.
Provide both external side dimensions and confirm square versus rectangular geometry. Select the exact carbon steel grade because the generic material name does not establish a designation. Define hot rolled, non-oiled delivered condition and the required dimensional tolerance.
For a building frame, specify member length, end preparation and connection details. No fixed dimensional variants or numerical mechanical results are supplied. General fluid, gas, boiler and hydraulic applications do not establish operating pressure or service approval. Broad certificate lists and fabrication services do not prove structural capacity or a qualified finished assembly for the chosen section.
