ASTM SS400 ST37-2 Cold rolled Carbon Steel Channels for ship building
Carbon channel steel has the advantages of adjustable size and high compressive strength. Although the section size of cold-formed section steel is light, it is very consistent with the stress characteristics of roof purlin, so that the mechanical efficiency of steel can be fully utilized. A variety of accessories can be connected into different combinations, with beautiful appearance. The use of steel purlin can reduce the weight of building roof and the amount of steel used in engineering, so it is called economic and efficient steel.
