1, cold galvanized tray process: cleaning steel surface chemical treatment for electroplating solution, plating with Zinc Oxide solution. DC pole to steel, a pair of zinc plate plating solution.

通电后锌以分子状态置换到钢材表面。如果添加光亮剂钝化反映云彩像光亮镀层。

When the power is turned on, the zinc is displaced to the surface of the steel by molecular form. If the brightener is added, the passivation reflects the clouds as bright as the coating.

2、热镀锌桥架的工艺过程：将钢件或铸件浸入熔融的锌液中在其表面形成锌 — 铁合金或锌和锌 — 铁合金覆盖层的工艺过程和方法。热浸镀锌层较厚，抗腐蚀能力强。热镀锌锌层过冷光源，但更薄，防锈能力较弱。

2. The process of hot-dip galvanizing bridge: the process and method of forming a zinc iron alloy or zinc and zinc iron alloy coating on the surface of molten steel by dipping steel or casting into molten zinc bath. Hot-dip galvanized layer is thicker and corrosion resistant. Hot galvanized zinc layer over cold light source, but thinner and less rust preventive ability.

3、主要生产不同的工艺，热镀锌电缆桥架是在锌锅溶液中通过，电镀锌桥架则是通过电极反应得到。

3 、 the main production of different processes, hot galvanized cable bridge is in the zinc pot solution through, the zinc plating bridge tray is obtained by electrode reaction.

4、应用在钢结构上的电镀锌桥架一般防锈效果都不是很好，小于主要镀锌量，和镀锌不均匀通常两三年都出现生锈，质量差的暴露在潮湿环境中十几天就生锈了。

4, the application in steel structure of electro galvanized bridge general antirust effect is not very good, mainly less than galvanized and galvanized uneven, usually two or three years appear rust, the poor quality of the exposure in the humid environment of ten days rust.
