Rectangular tube is an extruded product that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. Rectangular tube has square corners inside and outside, with no weld seam.
| Grade | Description |
|---|---|
| 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. |
| Grade | Description |
|---|---|
| 6061, 6063 | Heat treatable, structural alloy with medium strength and good weldability, formability, machinability, and relatively good corrosion resistance. |
| Grade | Description |
|---|---|
| 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. |
| 409 | Lowest cost in terms of stainless. Used in automotive exhaust systems. Its resistance to oxidation and corrosion is good, the finish or look does not matter. |
