Tubing & Profiles
Square Tubes
Structural hollow sections for frameworks, supports, and general construction.
Product Overview
Our square tubes are hollow structural sections (HSS) manufactured through electric resistance welding (ERW) processes. The square profile provides excellent load-bearing properties and is ideal for frameworks where flat surfaces are required for connections.
Square tubes offer superior torsional strength compared to round tubes and are widely used in building construction, trailers, machinery frames, and general fabrication projects across Zambia.
Key Features
Excellent Load-Bearing
Square shape provides superior strength for vertical and horizontal loads.
Flat Surfaces
Easy to connect, weld, and bolt due to flat external surfaces.
Torsional Strength
Superior resistance to twisting forces compared to open sections.

Square Tube vs Round Tube
Square Tubes
Better for frameworks requiring flat connection surfaces. Superior for compression and bending in structural applications. Easier to bolt and join.
Round Tubes
Better for fluid transport and applications requiring rotation. Superior torsional strength. More efficient for equal strength in all directions.
