In order to achieve the structural design of the shelf, the company selects high-quality steel and appropriate thickness according to the bearing capacity of customers' needs. Secondly, the surface treatment of the shelf is sprayed with plastic evenly and with strong adhesion to prevent the storage shelf from rusting during use. The waterproof and rust proof treatment can extend the service life of the storage shelf. Jincheng shelves are generally customized according to the customer's warehouse, storage items, shelf load-bearing and other specific conditions. The complexity of design, selected materials, material thickness, production process and installation complexity of different customers are different, which also determines the cost price. The welding process is a key part of the shelf process. The welding of the shelf is a local rapid heating and cooling process. The welding area cannot expand and contract freely due to the constraint of the surrounding workpiece body. After cooling, welding stress and deformation will occur in the weldment. Shelf installation is the last work of shelf supply, but it is also a very important step.
