Description

Pre Galvanised Square Tube is a durable steel tubing product designed for structural, fabrication, and construction applications where corrosion resistance and a clean finish are important. The tubing is manufactured from steel that has been galvanised prior to forming, providing a protective zinc coating that helps reduce the risk of rust and environmental damage. Its square profile offers balanced strength and stability, making it suitable for frames, supports, fencing, and general fabrication where reliability and consistent performance are required.

Key Features

  • Pre galvanised zinc coating helps protect the steel from corrosion and environmental exposure
  • Square steel profile provides strength and stability for structural and fabrication work
  • Available in sizes from 13 x 13mm up to 152 x 152mm
  • Multiple wall thickness options from 1.6mm to 6.0mm depending on size
  • Manufactured to recognised steel grades including SAE 1008 and SABS 1431 S355
  • Suitable for cutting, welding, and fabrication across many construction and engineering applications

Applications

  • Structural frames and support structures
  • Fencing, gates, and balustrade systems
  • Construction and infrastructure projects
  • General steel fabrication and manufacturing
