Square Tube is an extruded product that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. Square Tube has square corners inside and outside, with no weld seam.
|A500 Gr-B||Standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes.|
|A513||Offers high weldability and is used frequently in structural applications in bridges and buildings as well as in both the automotive and appliance industry.|
|304||Among the most commonly used grades across the industry, it offers resistance to corrosion. Has good formability and can be readily welded by all methods.|
|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.|
|409||Lowest cost in terms of stainless, used in automotive exhaust systems. It's resistance to oxidation and corrosion is good, the finish or look does not matter.|
|6061||Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.|
|6063||Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance.|
