热镀锌也叫热浸锌和热浸镀锌：是一种有效的金属防腐方式，主要用于各行业的金属结构设施上。是将钢、不锈钢、铸铁等金属浸入熔融液态金属或合金中获得镀层的一种工艺技术。是当今世界上应用最广泛、性能价格比最优的钢材表面处理方法。热镀锌产品对钢铁的减蚀延寿、节能节材起着不可估量和不可替代的作用，同时镀层钢材也是国家扶植和优先发展的高附加值短线产品。

Hot galvanization is also known as hot dip galvanization and hot dip galvanization: it is an effective metal anticorrosion method, mainly used in metal structure facilities in various industries.It is a technology of soaking steel, stainless steel and cast iron into molten liquid metal to obtain a coating or alloy.It is the most widely used and optimal performance price steel surface treatment method in the world.Hot galvanized products play an immeasurable and irreplaceable role in corrosion reduction and life extension, energy saving and energy saving materials. At the same time, coated steel is also a high value-added short-term product of national support and priority development.

热镀锌层与基体的结合强度高，可耐较大的摩擦及冲击；热镀锌层较厚（80-220g/㎡），耐蚀性更好。

The binding strength of hot galvanized layer and substrate is high and can withstand greater friction and impact; hot galvanized layer is thick (80-220g / ㎡) with better corrosion resistance.

热镀锌工艺广泛用于钢板、钢带、钢丝、钢管、结构件，零部件产品且其应用领域相当广泛，如轻工、家电、汽车、建筑行业等。在汽车工业中，可用于汽车车体、外壳、内板、地板等；在家电和轻工方面可用于各类家电的外壳和地板；在建筑业中，用于各类工业及民用建筑的轻钢龙骨、建筑层面板、瓦楞板、卷帘门等。

Hot galvanizing process is widely used in steel plate, steel strip, steel wire, steel pipe, structural parts, parts products and its application fields are quite wide, such as light industry, home appliances, automobile, and construction industry, etc.In the automobile industry, it can be used for automobile body, shell, inner plate, floor, etc., shell and floor for various household appliances and light industry; in the construction industry, light steel keel, building level panels, corrugated panels, rolling doors for various industrial and civil buildings.
