What are the material requirements for stainless steel door handles? There are many kinds of materials for handles, such as raw wood (mahogany) carved, but mainly stainless steel, zinc alloy, iron and aluminum alloy. Industrial handle materials are mainly stainless steel and zinc Alloy, aluminum alloy, nylon and other materials, because industrial handles require relatively high performance and use environment, the requirements for materials and processing techniques are relatively strict. Only stainless steel materials have different work requirements. There are 201 stainless steel, 306 stainless steel and 304 stainless steel. Of course, the performance and quality of industrial handles in all aspects are much better than ordinary handles. There are also many ways to handle the surface treatment of the handle. There are different surface treatment methods for handles of different materials. The surface treatment of stainless steel materials includes mirror polishing and surface drawing. The surface treatment of zinc alloy hinges generally includes galvanizing (white plating, plating, etc.).
