  customers' requirements

Supply a complete hollow section drawing before choosing galvanized carbon steel tube.

Section notation

The title names several square sizes and a 50x5 reference without a complete dimension convention. Confirm actual square or rectangular sides and steel designation; the shape field contains packing wording rather than usable section geometry.

Wall and zinc

The actual options pair a 12 m length with a 0.5–22 mm thickness range. Agree a compatible wall and outside section, then define the applicable 30–200 g/m² zinc coating measurement for the delivered tube.

• Actual carbon steel grade
• Outside section drawing
• Wall and dimensional tolerance
• Finished length and ends
• Zinc inspection requirements

Application evidence

Construction, fluid and boiler applications are listed broadly. Confirm the actual material standard and design tests; these labels provide no pressure rating, structural capacity or manufacturer provenance for the supplied section.
