304 stainless steel square tube is a high-strength material. The material also has added Mo and Cr, making it strong and corrosion-resistant. The square cross-section of the tube provides good geometric strength throughout the pipe. And 304 square stainless steel pipe can be made with many surface finishes, which is ideal for many decorative surfaces. We can use the square tube at 870°C, the primary choice for many ship railings and medical equipment.
