Imitation steel square lock, made of iron material, a lock with 3 keys, the same type of lock key can be opened, suitable for warehouses, factories, etc. I, the surface is smooth, smooth and easy to demoulding, in order to ensure the smoothness and smoothness of the product. Second, it won't rust, and there won't be any rust spots.3. During the plating process, the deformation of the original parts is small. After the surface is chrome plated, the hardness can be enhanced (HR65 or more), and the temperature resistance can reach 500℃, corrosion resistance, acid resistance and abrasion resistance. 4. If the part size is not in place, you can add a few c chromium to reach the size. Five, according to the characteristics of the product, to achieve visual and three-dimensional effects, to ensure the stable surface quality of the product.
