Square Structural Steel Tubing
Structural steel tubing is designed to provide strength and rigidity to structures while minimizing weight. Square tubing has a square cross-section, which makes it suitable for use in applications where rectangular shapes are needed, such as the construction of frames, supports, and other structures. It is often used to create complex structures or shapes.
