Q550 high strength steel plate advantage
it can reduce component size and structural weight, correspondingly reduce welding workload and welding material usage, reduce the use of various coatings (such as rust prevention and fire prevention), make transportation and installation easier, and reduce the processing, manufacturing, transportation, and installation costs of steel structures. High strength steel can reduce the amount of steel used, thereby greatly reducing the consumption of iron ore resources; The reduction of the amount of welding materials and various coatings (rust prevention, fire prevention, etc.) can also greatly reduce the consumption of non Renewable resource and reduce the damage to the environment caused by resource exploitation.
