What applications use rectangular stainless steel tubing?
Common applications include machine frames, food processing tables, conveyor structures, display fixtures, sign structures, vehicle exhaust systems, and architectural facades where both structural strength and corrosion resistance are required.
What is the structural difference between rectangular and square tube?
Rectangular tube has different second moments of area on each axis, making it stiffer in one bending direction. It is preferred for beams and horizontal supports carrying primary loads in one plane. Square tube provides equal stiffness in all lateral directions, making it better for columns and multi-axis loading.
