1,A common and highly effective process for steel mesh, which involves coating the steel with a layer of zinc to prevent rust.
Electro-Galvanizing: Provides a smooth, bright silver finish with a thin zinc layer. Good for indoor applications with moderate corrosion resistance.
Hot-Dip Galvanizing: Immerses the mesh in molten zinc, creating a thick, durable coating with a characteristic spangled pattern. Offers superior, long-lasting protection for harsh outdoor environments.
2,A dry finishing process where electrostatically charged paint powder is applied to a surface and then cured under heat. It creates a thick, durable, and attractive coating.
Key Features: Available in a wide range of colors (e.g., RAL codes), excellent UV resistance, superior abrasion resistance, and enhanced corrosion protection. Ideal for both aesthetic and functional purposes.
3,An electrochemical process primarily for aluminum mesh that enhances the natural oxide layer on the metal’s surface.
Key Features: Greatly improves corrosion and abrasion resistance. Allows for dyeing in various decorative and durable colors (e.g., bronze, black, gold) while maintaining the metallic luster.
4,Involves dipping the metal mesh (usually galvanized steel) into a fluidized bed of PVC plastisol and then heating it to form a seamless, flexible plastic layer.
Key Features: Provides excellent corrosion resistance and physical protection. Available in colors like green and black, it offers a comfortable grip and is commonly used for fencing and handrails.
5,While stainless steel is naturally corrosion-resistant, a chemical passivation process can be applied to remove free iron contaminants from the surface and maximize the inherent corrosion resistance of the chromium layer.
