Bridge erection is often used in our daily life. One of them is hot-dip galvanized bridge. It can be seen everywhere around us. It not only protects cables, but also ensures our daily power consumption. What are its characteristics?

钢的表面全层，无论其内部是凹处管件内角，还是其他任何涂层不易触及的角落，均应进行保护，熔融锌可均匀地覆盖。

The full surface layer of steel, whether its interior is concave, the inner corner of pipe fittings, or any other corner where the coating is not easy to touch, shall be protected, and the molten zinc can be evenly covered.

热浸锌层的硬度值比钢材还要高，因此其抗冲击性能和抗磨损性能都非常优异。

The hardness value of hot-dip galvanized layer is higher than that of steel, so its impact resistance and wear resistance are very excellent.

在边缘地带，锌层一般比其它部位厚，具有优良的韧性和抗磨损能力。与其它涂料相比，在边缘处，通常是薄的不易施工，易损伤和损坏，所以经常需要重新保养。

In the edge zone, the zinc layer is generally thicker than other parts, with excellent toughness and wear resistance. Compared with other coatings, at the edge, it is usually thin, difficult to construct, easy to damage and damage, so it often needs to be maintained again.

即使受到重大机械伤害，也要考虑到其他原因。造成少量锌层脱落，使铁基外露，此时周边锌层就会起到牺牲阳的作用，在这里对钢进行保护，使其不受腐蚀。与其它涂层相反，反之亦然，锈会立即形成，并在短时间内扩散到涂层的底部，造成涂层脱落。

Even in case of major mechanical injury, other reasons shall be considered. Cause a small amount of zinc layer to fall off and expose the iron base. At this time, the surrounding zinc layer will play the role of sacrificing yang to protect the steel from corrosion. Contrary to other coatings, and vice versa, rust will form immediately and spread to the bottom of the coating in a short time, causing the coating to fall off.

锌层在大气环境中的损耗非常缓慢，大约为1/17到1/18的钢铁腐蚀深，而且是可以预测的。它的使用寿命比其他涂层都长。

The loss of zinc layer in atmospheric environment is very slow, about 1 / 17 to 1 / 18 of steel corrosion is deep, and it can be predicted. Its service life is longer than other coatings.

镀层的使用寿命在特定环境下，主要取决于镀层的厚度。而且镀层厚度还受钢材厚度的影响，即越厚的钢材容易得到偏厚的镀层，所以在相同的钢结构中，厚的钢部位一定也要同时得到偏厚的镀层，以确保获得较长的使用寿命。

The service life of the coating mainly depends on the thickness of the coating in a specific environment. Moreover, the coating thickness is also affected by the steel thickness, that is, the thicker the steel is, it is easy to get a thicker coating. Therefore, in the same steel structure, the thicker steel parts must also get a thicker coating at the same time, so as to ensure a longer service life.

因美观大方艺术创意，或在特殊情况下严重腐蚀性环境使用时，热浸锌层可再施上部涂料处理，只需上部涂料的系统选择合理，施工较容易，其耐腐蚀性能比单独上部涂料及热浸锌寿命加起来，要好1.5~2.5倍。

Due to beautiful and generous artistic creativity, or when used in a severely corrosive environment under special circumstances, the hot-dip galvanized layer can be treated with the upper coating. As long as the system selection of the upper coating is reasonable, the construction is easier, and its corrosion resistance is 1.5 ~ 2.5 times better than the combined service life of the upper coating and hot-dip galvanizing alone.

用锌层对钢进行防护，除热浸镀锌法外，还有其他多种方法，其优劣对比，一般采用广泛，耐腐蚀效用大，且效率高，适合选择为热浸镀锌法。

In addition to the hot-dip galvanizing method, there are many other methods to protect steel with zinc coating. Its advantages and disadvantages are generally widely used, with great corrosion resistance and high efficiency. It is suitable to choose the hot-dip galvanizing method.
