The main steel grade includes Q235NH、Q355NH、Q550NH、SPA-H、Q345NQR2、RJ700MC.The main advantage of weather resistant steel products lie in high accuracy in sizes, stability in plate shape, premium performance in moilding and excellent performance in welding. Products are widely used in manufacturing all kinds of containers， including dry cargo box, refrigerated box, marine box, box board room, equipment box, explosion-proof box, storage box, etc. These products impose high requirements for corrosion resistance, welding performance and molding performance. Some containers for special use impose requirements for low impact performance in low temperature. Gauge cover (1.5-20)*(1010-1700)mm.
