Square Tubes
Square Tubes are hollow structural steel sections with equal-length sides, forming a perfect square profile. They are designed for strength, uniform load distribution, and versatility, making them suitable for light to medium structural applications, fabrication, and architectural projects.
They offer a perfect balance of strength, uniformity, and versatility, making them ideal for projects where aesthetics and structural integrity are both important.

Common Questions
Frequently Asked Questions
How are square tube sizes measured?
Square tube sizes are measured by outside dimensions (width × height), wall thickness, and length. For square tubes, the width and height are equal, along with the specified thickness, to determine strength and application suitability.
Are square tubes suitable for construction and structural framing?
Yes, square tubes are widely used for construction and structural framing. They provide high strength, uniform load distribution, and stability, making them ideal for frameworks, supports, and various building applications.
What is the difference between square tubes and rectangular tubes?
The main difference between square and rectangular tubes lies in their shape and load distribution:
- Square tubes: Equal sides, providing uniform strength and balanced load distribution in all directions
- Rectangular tubes: Unequal sides, offering greater strength in one direction, ideal for beams and spanning applications
Both are widely used in construction, fabrication, and structural projects depending on design requirements.
