Product List
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.

304 | Offers resistance to corrosion, has good formability and can be readily welded by all methods. One of the most commonly used grades across the industry. |
304L | Extra low carbon avoids harmful carbide precipitation due to welding. Same corrosion resistance as 304 with lower mechanical properties. |
316 | Better pitting and corrosion resistance than 304, as well as higher strength at elevated temperatures. 316 can be used for valves, marine equipment, pumps, and chemical equipment. |
316L | Extra low carbon avoids harmful carbide precipitation due to welding. Same excellent corrosion resistance as 316. It exhibits the same high strength, toughness and workability as 304 alloys. |
