What is the mild steel square tube?
The square tube is a welded hollow square-cut steel tube that is specifically designed to be used in all types of construction projects. Either the type A513 or A500 Grade B, depending on its size and wall thickness. The square steel tube shape design allows for increased rigidity and strength compared to other steel product shapes. For the grade ideal for all structural applications, general fabrication, manufacturing, and repairs. Square steel tubes can also be cut, formed, machined, and welded to your exact specification. The shape configuration allows for much greater strength and rigidity compared to angles or channels. This steel tube shape is easy to weld, cut form, and machine with proper equipment and knowledge.
