  Usage

  Building Construction

Galvanized square tube has three actual0.5–6.5mm wall-range/length pairings. The40×40,75×75 and20×40mm title sections need exact geometry confirmation.

Define the hollow section

Actual lengths are6m,6.4m and12m. Specify square or rectangular legs, wall, bore and corner requirements rather than assuming title dimensions are actual variants.

• Zinc-coating surface.
• Q235/Q345 family.
• SS400/S235/S355 alternatives.
• 1–12m length family.
• Multiple standard references.

Select actual material

Choose one grade and hot-dip acceptance specification. No zinc quantity or numerical strength is supplied.

Agree engineering evidence

Construction/fluid contexts do not establish pressure ratings, structural capacity or corrosion life. Request actual section, material and coating tests before assigning the tube to the intended assembly.
