Hot-dip galvanizing (Hot-dip zinc) : an effective way of metal corrosion protection, after rust removal, steel, stainless steel, cast iron and other metals are immersed in a zinc solution melted at about 500 ℃, so that the steel components surface attached to the zinc layer, thus playing a corrosion protection purposes. Hot-dip galvanising is the most widely used steel surface treatment method in the world.
Hot-dip galvanising is mainly used in industrial products, hot-dip galvanising layer is generally more than 35μm, the standard requirement is about 80μm, some even as high as 200μm, good coverage ability, dense plating layer, in the long years, even if the oxidation damage, but also will continue to indicate that the generation of a protective film, constantly protect the inner, mainly used in a variety of line fittings gold or an important long-lasting industrial products, like fibre optic cable fittings, wire clips, pole hoops and tower fasteners these fittings etc.
Electro-galvanising: The process of using electrolysis to attach a metal film to the surface of metal or other materials to prevent oxidation of the metal, which enhances the corrosion resistance of the metal, increases the hardness, prevents abrasion, improves electrical conductivity, smoothness, heat resistance and surface aesthetics.
Electro-galvanising: The plating layer is more uniform than the hot dip layer, generally thinner, ranging from a few microns to tens of microns. Through electroplating in order to enhance the corrosion resistance of the metal, increase hardness, prevent abrasion, improve electrical conductivity, smoothness, heat resistance and surface aesthetics, mainly used in a variety of decorative or luxury goods and consumer goods, such as watches and car exterior films.
