Color steel tile is made of color coated steel plate, which is processed into various profiled plates. It is widely used. Its corrosion resistance and water resistance are the necessary properties when it is installed in the open air all the year round. Today, I will introduce the detailed knowledge of its water resistance:

一般彩钢瓦在风吹雨打几年之后就会出现锈斑、腐蚀。如果想让彩钢瓦延长寿命怎么做呢？

Generally, the color steel tile will appear rust and corrosion after several years of wind and rain. What to do if you want to prolong the service life of color steel tile?

可以每涂料用量不低于1公斤。在不显着提高施工成本的情况下，可少延长彩钢瓦使用寿命5~8年这样延长寿命，降低施工成本。

The amount of coating can be no less than 1 kg per square meter. In the case of not significantly increasing the construction cost, the service life of the color steel tile can be extended for at least 5-8 years so as to extend the service life and reduce the construction cost.

要是彩钢瓦表面已经有生锈腐蚀的痕迹时就要打磨机或者砂纸将表面的浮锈打磨干净，这些办法都可以将彩钢瓦防水的性能提高，让彩钢瓦不在被腐蚀，破裂。

If there are signs of rust corrosion on the surface of the color steel tile, it is necessary to polish the floating rust on the surface with a grinder or sandpaper. These methods can improve the waterproof performance of the color steel tile, so that the color steel tile is not corroded or cracked.

彩钢板为什么会漏水呢？

Why does the color steel plate leak?

有以下几种可能，彩钢瓦的坡度小，保温层的暴露，安装时不作相应的处理，导致雨水直流进保温夹层，形成了所有为的"雨水倒流".彩钢瓦接缝很会导致彩钢瓦漏水，接缝时，看上去很好，但一条长长的缝隙经不起一小时的雨水冲刷，渗漏将乘虚而入。彩钢板安装时的钉子眼，也是漏水的直接原因，所以不仅要产品质量好，而且安装的技术也要到位。

There are several possibilities as follows: the gradient of the color steel tile is small, the insulation layer is exposed, and no corresponding treatment is taken during installation, resulting in the rainwater flowing directly into the insulation interlayer, forming all the "rainwater backflow". The color steel tile joint will cause water leakage of the color steel tile. When the joint is made, it looks very good, but a long gap can not withstand an hour of rainwater washing, and the leakage will take advantage of the emptiness. The nail hole of color steel plate installation is also the direct cause of water leakage, so not only the product quality is good, but also the installation technology is in place.
