Square Tubing

Square Tubing refers to a type of hollow metal tube with a square or rectangular cross-section. This structural shape is commonly used in various applications across different industries.



Square tubing can be made from various materials, including steel, stainless steel, aluminum, and other alloys. The material choice depends on factors such as strength requirements, corrosion resistance, and the specific application.


The dimensions of square tubing are specified by its outside dimensions, including the width of the sides and the wall thickness. Common dimensions are specified in inches or millimeters.


Construction: Square tubing is widely used in construction for structural components such as columns, beams, and supports.

Manufacturing: It is utilized in the manufacturing of machinery, equipment, and other products requiring structural integrity.

Frames and Structures: Square tubing is commonly used for creating frames, structures, and frameworks in various industries.

Furniture: It is a popular choice for manufacturing furniture frames due to its structural stability.

Architectural Applications: Square tubing is used in architectural designs for its clean and modern appearance.

Strength and Rigidity: Square tubing provides excellent strength and rigidity, making it suitable for applications where structural integrity is crucial.

Welding and Fabrication: Square tubing is easily weldable, allowing for customization and fabrication to suit specific project requirements. It can be cut, bent, and joined through welding processes.

Finishes: Square tubing can have different finishes based on the material and application. Finishes may include plain (uncoated), painted, powder-coated, or coated for enhanced corrosion resistance.

Seamless vs. Welded: Similar to round tubing, square tubing can be seamless or welded. Seamless tubing is produced without a seam, while welded tubing is created by welding together strips of metal.
