The hot rolling technolodge of Q355NH, Q500NH, Q550NH steel coil

The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.

For Q355NH, Q500NH, Q550NH steel coil, automobile steel sheet materials, it must have excellent pressure-bearing performance. Automobile steel sheets of substandard quality are prone to fracture problems, which also cause waste and consumption of production materials, and directly increase the production cost of automobiles. Generally, the qualified automobile steel sheets used in automobile manufacturing are high-strength steel plates. The high-quality automobile steel sheets are more durable and improve the quality of the entire automobile.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished Q355NH, Q500NH, Q550NH steel coil steel plates products according to the client needs. Realize the service from product drawings-steel plate procurement-steel plate cutting-steel plate processing Q355NH, Q500NH, Q550NH steel coil steel plate distribution services, so as to save customers manpower and material resources.
