After we receive orders for steel plates from other companies, we first transport them to our own factory, where they are sorted and the plates of the same specification are listed together to be processed. After the steel plate is stamped, built and other operations, it is put on the galvanized square pipe steel pipe assembly line, and the follow-up operation is completely operated by the machine automation, without manual intervention, after the forging is completed, it is put into cold water for cooling, and the curing and shaping operation is carried out, and the surface is coated with anti-corrosion and lubricating liquid, and finally the order sampling work is carried out, and the package is sent to the customer.
