    Carbon Hollow Section

    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.

    Stainless Hollow Section

    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.
