    Usage
    Building Construction

Galvanized square pipe has three actual wall-range/length pairings. The0.5–6.5mm label pairs with6m,6.4m and12m, while section dimensions require actual selection.

Specify legs and wall

20×20/25×25mm are title and family references, not separate actual variants. Confirm square or rectangular geometry, wall thickness and corner requirements together.

  • Square section field.
  • Zinc-coating surface.
  • Non-oiled description.
  • 1–12m/custom length family.
  • Cutting and bending services.

Verify the requested material

Q700 is not confirmed by the Q235/Q345/S235-family data. Request actual chemistry, condition and mechanical tests before assigning a high-strength grade.

Agree fabrication acceptance

Provide actual connection and dimensional criteria. Building and fluid-service contexts do not establish load capacity, pressure ratings, zinc quantity or corrosion life for the chosen tube without selected-product evidence.
