Steel plates are hot rolled products that have a relatively high thickness. Products having a thickness of over 4.5 mm are classified as steel plates, and those having a thickness of over 100 mm are called thick steel plates. Slabs of steel plates made through continuous casting are tailored to the dimensions specified by the customer through rolling and cooling before being cut into their final sizes.
This product specification is subject to change, so please check the latest specifications when ordering or consult with the person in charge.
