Technical requirements for surface treatment of anticorrosive bridge frames. Before using the bridge, we need to treat its surface, so as to ensure its safe use, and anti-corrosion bridge treatment method is one of them. It is manufactured in a specific technological environment and has good anti-corrosion performance. What are the technical requirements of anti-corrosion bridge surface treatment? The bridge factory will give you a detailed introduction below.

热镀锌桥架主体对1.5~3mm厚度，小平均厚度≥6m,小局部厚度6m >3mm厚度 60am局部6m防护处理的表面光泽应不低于60%.检测方法：按GB1743,油膜光泽度测定法，用光泽度仪测量数字直接显示。表面防护层应具有表4中规定的3级耐盐雾性。

The surface gloss of the main body of hot-dip galvanized bridge should not be less than 60% for protection treatment of 1.5-3 mm thickness, minimum average thickness (> 65 am), minimum local thickness (> 6 mm) and local thickness (> 3 mm), 60 am). Detection method: According to GB1743, oil film gloss measurement method, digital direct display is measured by gloss meter. The surface protective layer shall have the salt fog resistance of Grade 3 specified in Table 4.

当宽度大于400mm时，极限偏差为±4mm,当宽度小于等于400mm时，极限偏差为±3mm说明：盖板取正偏差，槽底宽取负偏差，热镀锌防护处理平面度允差每米不大于8mm,电镀锌和喷漆，防护处理平面度允差每米不大于4mm.

When the width is more than 400 mm, the limit deviation is (+4 mm). When the width is less than or equal to 400 mm, the limit deviation is (+3 mm). This means that the cover plate is positive deviation, the bottom width of the tank is negative deviation, the flatness tolerance of hot-dip galvanizing protection treatment is not more than 8 mm per meter, the flatness tolerance of galvanizing and spraying paint is not more than 4 mm per meter.

以上是对防腐桥架表面处理的技术要求的简单介绍，防腐桥架在使用的时候适合在腐蚀性环境、大跨距、重载荷条件下进行使用，且它具有很高的机械强度，防火性能强，抗老化性能强，造型美观，安装方便，并且它的各种性能大大优于其他的桥架制品。

Above is a brief introduction of the technical requirements for surface treatment of anti-corrosion bridge. Anti-corrosion bridge is most suitable for use in corrosive environment, long-span, heavy load conditions. It has high mechanical strength, strong fire resistance, anti-aging performance, beautiful appearance, convenient installation, and its various properties are much better than other bridge products.
