Main application: Mild steel plate,also named as common carbon structural steel plate.For thin thickness belows 16mm,coils type is ok for offer,However re-coil plate owned lower mechanical properties than medium steel plate.Carbon steel plates are used to produce structural parts of the bolted and welded steel in industrial area.
Rolling range: Thickness*Width*Length 3-650mm*1200-4200mm*5000-18000mm
Surface Treatment: Coated,Shop primer painting
Test: Low temperature impacting test,Ultrasonic examination,Normalized,NACE,HIC,SSCC and Third party inspections by end user.
