The objects of surface treatment are very wide, from traditional industry to high-tech industry, from metal surface to plastic and non-metallic surface. It makes the material more corrosion-resistant, wear-resistant and heat-resistant. It prolongs the service life of the material. In addition, it improves the characteristics of the material surface, luster and beauty, and improves the added value of the product. All these processing technologies that change the physical, mechanical and chemical properties of the material surface are collectively referred to as surface treatment or surface finishing.

        Although the surface treatment industry is not the mainstream of the industry, only through surface treatment can the characteristics and value of finished products be brought into full play. Industrial technologies such as plating, anodizing, conversion coating and coating are applied to change one or more items such as appearance, corrosion prevention, weldability, conductivity, lubricity, wear resistance and adhesion.

        Except for a few surface treatment processes completed by customers, Vanroad is responsible for the completion of Vanroad's products. At present, the surface treatment processes used include magnetic grinding, vibration grinding, polishing, sand blasting, surface wire drawing, cleaning, chemical etching, radium carving, electroplating (electro galvanized, electro tinned, electro nickel, electro silver, electro gold, electro galvanized nickel), chemical nickel plating, electrophoresis Anodizing, spraying, hot-dip galvanizing, Dacromet, PVD, phosphating, etc., with mature and stable supply chain cooperation, can meet most of the surface treatment needs of customers. At the same time, many people in Vanroad team have more than ten years of experience in sales, technology and quality of surface treatment company, and can provide customers with comprehensive and reasonable feasibility assessment and suggestions on surface treatment process in the project planning stage, which is deeply trusted by customers.
