Galvanizing for climbing frame of Dalian light steel plate mesh is a surface treatment technology, which is divided into cold galvanizing and hot galvanizing. The hot galvanizing technology is commonly used. With the rapid development of cold rolled strip steel in the past three decades, the hot galvanizing industry has been greatly improved, and is widely used in surface treatment of metal products. Steel mesh is a kind of metal screen in the industry. It is also known as metal plate mesh, diamond mesh, iron plate mesh, metal expansion mesh, heavy steel plate mesh, pedal mesh, perforated aluminum plate mesh, stainless steel plate mesh, granary mesh, antenna mesh, filter element mesh, audio mesh, etc.
