What is the BBNSteel SA709 Gr 50W structural steel quotation

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials SA709 Gr 50W structural steel. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

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 SA709 Gr 50W structural steel, 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.

We have efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel SA709 Gr 50W structural steel products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.

The preparation of SA709 Gr 50W structural steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for SA709 Gr 50W structural steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
