is the first agent for big mills, and the carbon steel is the main products. It can suppliy different carbon steels such as A283, A36. SS400, S235. ST37-2, FE460, Q235B etd.

 

A283Gr.C is a kind of carbon steel under specification ASTM A283/A283M " Standard Specification for Low and Intermediate Tensile Strength Carbon Steel Plates". There are two grade under this specification: Grade C and Grade D, and Grade C is a common required steels. A283Gr.C is a carbon steel for general structural application.
