There are many kinds of materials for handles, such as raw wood (redwood), but mainly stainless steel, zinc alloy and iron and aluminum alloy. Industrial handle materials are mainly stainless steel and zinc alloy, aluminum alloy, and nylon. Due to the high requirements of industrial handles in terms of performance and use environment, the requirements for materials and processing techniques are relatively strict. Only stainless steel materials according to different work requirements are 201 stainless steel, 306 stainless steel and 304 stainless steel. Of course, the performance and quality of industrial handles are much better than ordinary handles.
There are many ways to handle the surface of the handle. Different handles have different surface treatment methods. The surface treatment of stainless steel has mirror polishing and surface drawing. Zinc alloy hinge surface treatment is generally galvanized (white plated, chrome plated), bright chrome plated, chrome plated chrome, matt chrome, black surface, black paint.
