For the roof color plate, the color plate should be closed at the roof and eaves to prevent rainwater from entering the roof more effectively. At the ridge of the roof, the outer plate of the roof can fold up the chassis between the end ribs of the steel plate with the edge closing tool.

彩钢板用于所有坡度低于二分之一屋面钢板的上端，以保证在泛水板或盖板下方由风吹入的水不会流入建筑之中。

The color steel plate is used for the upper end of all roof steel plates with a slope of less than one-half to ensure that the water blown by the wind under the flashing plate or cover plate will not flow into the building.

穿透式固定是彩钢板安装的更常用方式，即用自攻螺钉或铆钉将彩板固定在支撑件(如檩条)上，一般用于屋面板的安装，彩板的侧向和端部搭接，安装每一块钢板时，应将其边搭接准确地放在前一块钢板上，并与前一块钢板夹紧，直到钢板的两端都固定为止。一种简单而有效的方法是用一对夹口钳分别夹住所搭接的钢板。

Penetration fixation is the most commonly used method for installation of color steel plate, i.e. fixing color steel plate on supporting parts (such as purlin) with self tapping screws or rivets, which is generally used for installation of roof panel. The side and end of color steel plate are overlapped. When installing each steel plate, the edge overlap shall be accurately placed on the previous steel plate and clamped with the previous steel plate until both ends of the steel plate are fixed. A simple and effective method is to clamp the overlapped steel plates with a pair of pliers.

固定螺钉选用时应该按照结构的使用寿命选择固定件，而且特别注意外覆材料的寿命与指定的固定件寿命是否一致。

When selecting fixing screws, the fixing parts shall be selected according to the service life of the structure, and special attention shall be paid to whether the service life of the covering material is consistent with that of the specified fixing parts.

同时注意钢檩条厚度不能超过螺钉的自钻能力。目前供应的螺丝可带有塑料头、不锈钢顶盖或涂有特殊的耐久保护层。

At the same time, the thickness of steel purlin shall not exceed the self drilling capacity of screw. The screws currently available can have plastic heads, stainless steel covers or be coated with a special durable protective coating.

另外，除暗扣固定用螺钉外，其他螺钉均带有防水垫圈，而且针对采光板和特殊风压下的情况均配有相应的专用垫圈

In addition, in addition to the screws for snap fastening, other screws are provided with waterproof washers, and the corresponding special washers are provided for the lighting panel and special wind pressure
