Bright Rectangular Steel Tube

Bright Rectangular Steel Tube is precision cold-drawn for accurate dimensions and a smooth surface, helping reduce machining, improve fabrication efficiency, and deliver reliable performance in structural and industrial applications.

Multi-pass cold drawing provides consistent width, height, and wall thickness, reducing machining allowance and improving assembly accuracy for automated production.

Controlled bright annealing produces a clean metallic surface with reduced oxide scale, making the tube suitable for painting, plating, or decorative applications.

Controlled heat treatment balances strength and ductility, improving bending, welding, and machining performance while reducing deformation.

Mechanical straightening and online dimensional inspection help maintain consistent straightness for structural fabrication and precision equipment.

Custom Cutting: Precision cut-to-length services to minimize waste on your production line.
