Hot-rolled Steel Plates & Coils

ZC hot-rolled steel plates and coils cover structural, shipbuilding, pipeline, and pressure vessel grades from 6 mm to 220 mm thickness. Supply standards include EN 10025, ASTM A36/A572/A516, JIS G3101/G3106, API 5L, and GB/T 713.

Applications

→ Construction and infrastructure — structural steelwork, bridges, and building frames
→ Shipbuilding — hull plating, decks, and structural components certified by classification societies
→ Railway — track beds, bridges, and railway infrastructure components
→ Oil and gas — pipeline plate (API 5L grades), pressure vessel shell plates, and offshore structures
→ Power generation — pressure vessel steel for boilers, reactors, and storage tanks
