The company's logistics department has the ability to monitor the whole process of logistics. We monitor the goods in transit through advanced information technology and communication technology, timely discover and handle problems in the transportation process, and ensure the steel materials are delivered to the destination in a timely and safe manner. The professional logistics team provides powerful support for good comments of customers and good reputation of the company.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the A36 steel and A573 Grade 58 steel supplier plate should be derusted before cutting.
