High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the NM450 sheet price, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.
