Square Steel Tubing-4" x 4" x 11ga (0.120")-Select Length

4" × 4" × 11ga (0.120") Square Steel Tubing — MADE IN THE USA

Square Steel Tubing is a strong, versatile, and easy-to-work-with steel product designed for a wide range of structural, industrial, and fabrication applications. Each piece is precision cut from high-quality A500 Grade B mild carbon steel, ensuring consistent wall thickness, excellent strength, and reliable performance in demanding environments.

This square steel tube is commonly used for welding projects, frames, trailers, racks, agricultural equipment, braces, supports, and general shop fabrication. The square profile provides superior strength and rigidity compared to angle or flat bar, making it ideal for both structural and decorative uses.

The smooth, clean surface finish allows for easy cutting, drilling, welding, and forming with standard shop tools. Whether you’re working in a professional fabrication shop or on a home DIY project, this tubing offers dependable results and long service life.

Each piece is cut to length and supplied in raw mill condition, ready for fabrication or finishing. Steel may show light mill scale or minor surface marks, which are normal for hot rolled steel and do not affect performance.
