安装要点与注意事项​

Installation points and precautions

（一）基层处理与骨架搭建​

（1） Grassroots treatment and skeleton construction

在安装彩钢瓦之前，需对屋面或墙面基层进行处理，确保基层平整、干净、无杂物。对于钢结构骨架，要严格按照设计要求进行焊接或螺栓连接，保证骨架的强度和稳定性。骨架间距应根据彩钢瓦的版型和规格合理确定，一般波浪形彩钢瓦的骨架间距不宜超过 1.5 米 ，以确保彩钢瓦能够牢固固定，避免因间距过大导致变形或漏水。​

Before installing color steel tiles, it is necessary to treat the base layer of the roof or wall to ensure that it is flat, clean, and free of debris. For steel structure skeleton, welding or bolt connection must be strictly carried out according to design requirements to ensure the strength and stability of the skeleton. The spacing between the skeletons should be reasonably determined according to the pattern and specifications of the color steel tiles. Generally, the spacing between the skeletons of wavy color steel tiles should not exceed 1.5 meters to ensure that the color steel tiles can be firmly fixed and avoid deformation or water leakage caused by excessive spacing. ​

（二）彩钢瓦铺设与固定​

（2） Laying and fixing of color steel tiles

铺设彩钢瓦时，应从屋面或墙面的一端开始，逐块进行铺设。相邻彩钢瓦之间要保证有足够的搭接长度，通常横向搭接不小于一个波峰，纵向搭接不小于 200 毫米 ，并使用专用的防水密封胶或密封条进行密封处理，防止雨水渗漏。固定彩钢瓦时，应使用自攻螺丝或钻尾螺丝，螺丝间距要均匀，一般为 300 - 400 毫米 ，螺丝应垂直固定在骨架上，避免倾斜或松动。同时，要注意在螺丝头部加装防水垫片，进一步增强防水性能。​

When laying color steel tiles, they should be laid piece by piece starting from one end of the roof or wall. There should be sufficient overlap length between adjacent color steel tiles, usually with a horizontal overlap of not less than one wave peak and a vertical overlap of not less than 200 millimeters. Special waterproof sealant or sealing strip should be used for sealing treatment to prevent rainwater leakage. When fixing color steel tiles, self tapping screws or drill tail screws should be used, and the spacing between screws should be uniform, generally 300-400 millimeters. The screws should be fixed vertically on the frame to avoid tilting or loosening. At the same time, it is important to install waterproof gaskets on the screw heads to further enhance their waterproof performance. ​

（三）细部处理与验收​

（3） Detail processing and acceptance

在彩钢瓦安装的细部节点，如屋脊、檐口、天沟、阴阳角等部位，要进行特殊处理。屋脊处应安装专用的屋脊盖板，确保密封严实；檐口处要设置滴水板，防止雨水顺墙面流下；天沟要保证排水通畅，坡度不小于 2% ，并做好防水处理。安装完成后，要对整个彩钢瓦工程进行全面验收，检查彩钢瓦的铺设是否平整、固定是否牢固、密封是否良好，如有问题及时整改，确保工程质量。

Special treatment is required at the detailed nodes of the installation of color steel tiles, such as ridges, eaves, gutters, and corners. A dedicated ridge cover plate should be installed at the ridge to ensure a tight seal; Dripping boards should be installed at the eaves to prevent rainwater from flowing down the wall; The gutter should ensure smooth drainage, with a slope of not less than 2%, and be well waterproofed. After installation, a comprehensive acceptance of the entire color steel tile project should be carried out to check whether the laying of the color steel tiles is flat, whether they are firmly fixed, and whether the sealing is good. If there are any problems, they should be rectified in a timely manner to ensure the quality of the project.

最后虽然彩钢瓦具有一定的耐腐蚀性，但长期暴露在户外环境中，仍可能出现腐蚀、生锈现象。对于出现轻微锈蚀的部位，可使用砂纸或钢丝刷将锈迹打磨干净，然后涂刷防锈漆和防腐涂料进行防护。对于锈蚀严重的区域，应及时更换彩钢瓦，防止锈蚀进一步扩大。在日常使用中，要避免彩钢瓦与酸、碱等腐蚀性物质接触，如不慎接触，应立即用清水冲洗干净，并进行防腐处理。​​

Although color steel tiles have a certain degree of corrosion resistance, long-term exposure to outdoor environments may still result in corrosion and rusting. For areas with slight rust, sandpaper or wire brush can be used to polish the rust clean, and then anti rust paint and anti-corrosion coating can be applied for protection. For areas with severe corrosion, color steel tiles should be replaced in a timely manner to prevent further expansion of corrosion. In daily use, it is necessary to avoid contact between color steel tiles and corrosive substances such as acids and alkalis. If they accidentally come into contact, they should be immediately rinsed with clean water and treated with anti-corrosion measures. ​​
