Hot rolled steel products are divided into two groups: hot rolled coils produced through hot rolling and hot rolled steel plates, which are made by cutting material from hot rolled coils. Slabs produced from a continuous casting system are rolled, cooled and coiled into the sizes required by the customers.
This product specification is subject to change, so please check the latest specifications when ordering or consult with the person in charge.
