A709 Grade 50S steel plate

A709 Grade 50S steel grade is a high strength low alloy structural carbon steel used in building bridge projects.

Compare A709 Gr.100, and A709 Gr.50w grade, A709 Gr.50S has a lowest yield strength in 345Mpa in usual. A 709 Gr.50S requests killed or semi-killed in manufacture.
supply A709 Gr.50S many years in China mainland bridge projects. We also have many stock sizes in A709 Gr.50S for urgent need to our customers. Now, we are enlarging our oversea steel market in A709 Gr.50S steel plates.
