At present, the main grades include two parts: re-rolling grades, Q215B and SPHC for domestic, SPHT1、SPHC(B)、DD11、HR 235(B)、SAE1006、SAE1008 for export; Structural grade, Q235B for domestic, S235JRB、SPHT2、A36B、SS400B for export. The advantages of ESP hot-rolled products are thin gauge, high dimensional accuracy, excellent processing performance and high yield. The thin gauge hot rolled coil has great potential market for hot rolled instead of cold rolled. The ESP can meet the needs of shearing, rolling, bending, punching and simple drawing. Widely used in welded pipe, steel structure, cable tray, shelves, hardware, machinery, electrical cabinets, vehicles and other industries.
