Our company can produce JIS SM490A plates, EN10025-2 S355J2 structural steel plates and sheets up to 400mm thickness. S355J2 steel consists of S ( for structural steel), 355 (indicates the minimum specified yield strength value in MPa for thickness less than 16mm), J2( for a minimum impact energy value of 27J at -20ºC). EN S355J2 structural steel plates are suitable for cold flanging, delivery condition normalized rolled or as rolled.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products JIS SM490A plates price concessions, rich industry experience, complete varieties.
