一、在屋顶及屋檐处将彩钢板进行相应的收边工作，其目的是为了更有效地阻止雨水进入屋面以内。
1、 The color steel plate shall be subject to corresponding edge closing at the roof and eaves in order to more effectively prevent rainwater from entering the roof.
二、屋面彩钢板在屋脊的地方，可用收边工具将位于彩钢板终端肋条之间的底盘向上折。它用于所有坡度低于1/2(250）屋面彩钢板的上端，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。其具体操作方法是：把收边工具位于钢板终端底盘之上，尽快将工具滑于彩钢板之上，越里越好。用工具握住彩钢板终端，将底盘往上折，上折约800。如上所述，折弯每一底盘。当板被用在坡度低于1/5(100）的屋面时，应将彩钢板下端的底盘端部稍微向下弯曲(呈唇状)，可用同一收边工具来实现，这样可保证雨水顺着彩钢板终端被排出，并且不会因毛细或风力作用回流至平底盘的下边。
2、 At the ridge of the roof, the chassis between the terminal ribs of the color steel plate can be folded up with a trimming tool. It is used at the upper end of all roof color steel plates with a slope lower than 1 / 2 (250), so as to ensure that the water blown in by the wind under the flashing plate or cover plate will not flow into the building. The specific operation method is: place the edge closing tool on the steel plate terminal chassis, slide the tool on the color steel plate as soon as possible, and the more inside, the better. Hold the color steel plate terminal with a tool and fold the chassis up for about 800. Bend each chassis as described above. When the plate is used on the roof with a slope of less than 1 / 5 (100), the chassis end at the lower end of the color steel plate shall be slightly bent downward (lip shaped) and can be realized with the same edge closing tool, so as to ensure that the rainwater is discharged along the end of the color steel plate and will not flow back to the lower edge of the flat bottom plate due to capillary or wind force.
向下折边的操作必须在屋面彩钢板被固定以后，适当张开下撬工具的口，将工具夹住底盘端，尽量向里推。工具紧贴在底盘端部，同时将手柄摇动约200，这样在彩钢板的端部会形成一向下折边。
After the roof color steel plate is fixed, properly open the opening of the prying tool, clamp the tool on the chassis end and push it inward as far as possible. The tool clings to the end of the chassis and shakes the handle for about 200, so that a downward folding edge will be formed at the end of the color steel plate.
外形彩钢板都有相应的成型泡沫密封条。当它们被嵌在屋檐支撑面和屋面板下边之间时（用作屋檐密封)，这一底部密封带可以防止灰尘、昆虫、鸟、啮齿动物以及雨水进入肋条空间内。还可以沿泛水板和盖板的下方，将一顶部有轮廓的成型条嵌入泛水板下方和屋面彩钢板顶面之间，并用双面胶进行适当的固定，可以起到类似的密封作用。否则会造成房屋的漏水。
The shape color steel plate has corresponding formed foam sealing strip. When they are embedded between the eaves support surface and the lower edge of the roof panel (used as eaves seal), this bottom sealing belt can prevent dust, insects, birds, rodents and rainwater from entering the rib space. A molding strip with contour on the top can also be embedded between the lower part of the flashing plate and the top surface of the roof color steel plate along the lower part of the flashing plate and the cover plate, and properly fixed with double-sided adhesive tape, which can play a similar sealing role. Otherwise, it will cause water leakage of the house.
三、对于非常长的屋面彩钢板，应设置伸缩节点，这对于穿透固定式来说，在两伸缩节点之间，只能设置一个穿透固定的搭接。
3、 For the very long roof color steel plate, expansion joints shall be set. For the penetration fixed type, only one penetration fixed lap joint can be set between the two expansion joints.
四、一般而言，用于屋面彩钢板的所有金属中，钢的热胀冷缩到目前为止是最低的。事实上，在彩钢板的终端和最后支撑之间的膨胀或收缩位移只是表中所显示数据的一小部分，因为被固定的彩钢板位移，通常是从中心开始趋向于彩钢板的每个端部。每端的位移量只是膨胀或收缩量的一半。同样在建筑结构或屋面框架中也有一些温度变化位移，尽管不如屋面那么大，但仍减少了屋面彩钢板和其支撑面之间的位移。最终，由于条的屈曲，特别是在跨中，更进一步减少了这种差动位移。
4、 Generally speaking, among all the metals used for roof color steel plate, the thermal expansion and cold contraction of steel is the lowest so far. In fact, the expansion or contraction displacement between the end of the color steel plate and the final support is only a small part of the data shown in the table, because the displacement of the fixed color steel plate usually tends to each end of the color steel plate from the center. The displacement at each end is only half of the expansion or contraction. Similarly, there are some temperature change displacements in the building structure or roof frame. Although it is not as large as the roof, it still reduces the displacement between the roof color steel plate and its supporting surface. Finally, this differential displacement is further reduced due to the buckling of the strip, especially in the middle of the span.
