彩钢板在剪截应用时，表面常常会发生一种缺陷表面压斑缺陷，该缺陷是彩涂钢板镀层烤制、制冷后放卷时，因为放卷支撑力造成镀层表面的轻度形变，彩钢板有时候表面展现出不光滑,主要表现出了视觉效果由此可见的压斑形状。彩钢板轻度的压斑缺陷会随彩钢板储放時间的增加而慢慢消退，通过加温也可清除。可是彩钢板比较明显的压斑缺陷即使选用以上对策也不可以清除，进而危害客户应用。
During the application of color steel plate in cutting, a defect surface pressure spot defect often occurs on the surface. This defect is that when the color coated steel plate coating is baked and cooled, the coating surface is slightly deformed due to the unwinding support force. Sometimes the surface of color steel plate is not smooth, mainly showing the visual effect. Therefore, the pressure spot shape can be seen. The slight pressure spot defect of color steel plate will gradually subside with the increase of storage time of color steel plate, and can also be removed by heating. However, the obvious pressure spot defects of color steel plate can not be removed even if the above countermeasures are selected, which will endanger the application of customers.
彩钢板压斑是生产过程中形成的一种缺陷，若是在生产过程中找寻造成这类缺陷的缘故及影响因素，必须通过多次关机查排，危害生产规划，提升产品成本。因而彩钢板必须根据试验室仿真模拟、拷贝这类缺陷，并对它进行点评，从各个领域找寻造成缺陷的缘由与危害这类缺陷的要素。
Color steel plate plaque is a defect formed in the production process. If you find the causes and influencing factors of such defects in the production process, you must shut down for inspection and troubleshooting for many times, endanger the production planning and increase the product cost. Therefore, the color steel plate must simulate and copy this kind of defect according to the laboratory simulation, and comment on it, so as to find the cause of the defect and the elements endangering this kind of defect from various fields.
这种情况关键出现在两层彩钢板和单面彩钢板的房顶。工程施工流程中，攻牙力过大、过轻，自攻皮垫倾斜、彩钢板很有可能造成自攻皮垫形变、掉下来或产生球面，导致平屋面表面一点一点漏水，根据保温材料沉积，日积月累，导致多一点漏水。除此之外，彩钢板漏水的关键因素之一是自攻部位有误，彩钢板下漏钢檩条立即成桩。
The key to this situation is the roof of two-layer color steel plate and one-sided color steel plate. In the construction process of the project, the tapping force is too large and too light, the self tapping leather pad is inclined, and the color steel plate is likely to cause the self tapping leather pad to deform, fall down or produce spherical surface, resulting in water leakage on the flat roof surface bit by bit. According to the deposition of thermal insulation materials, it will accumulate over time, resulting in more water leakage. In addition to the leakage of color steel purlin, one of the key factors is the leakage of color steel purlin.
彩钢板这类漏水状况在沒有单面彩钢板保温系统的平屋面构造中很有可能并不显著，彩钢板根本原因是降水根据厚钢板与屋面檩条的触碰位置漏水后立即散掉，不一定滴得迅速。
The water leakage of color steel plate may not be significant in the flat roof structure without single-sided color steel plate insulation system. The root cause of color steel plate is that the precipitation is scattered immediately after the water leakage according to the contact position between thick steel plate and roof purlin, which may not drip quickly.
彩钢板水准钢筋搭接和竖直钢筋搭接，彩钢板搭接处漏水。假如彩钢板瓦波过低或降水过多超出瓦波，彩钢板非常容易产生大规模漏水，找不着漏水点。一旦产生，就难以修补。彩钢板这样的事情在斜面房顶中更加普遍。关键因素是两板重合太松，自攻不全产生间隙等。轻钢结构平屋面施工过程中，屋顶瓦漏水也是普遍状况。在多雨季节，尤其是降雨量比较大时彩钢板，降水的溅出会根据房脊瓦下边二块彩钢板连接处的间隙，产生大规模漏水。
The color steel plate is overlapped with horizontal reinforcement and vertical reinforcement, and there is water leakage at the overlap of color steel plate. If the tile wave of color steel plate is too low or the precipitation exceeds the tile wave too much, the color steel plate is very easy to produce large-scale water leakage and cannot find the water leakage point. Once produced, it is difficult to repair. Things like colored steel plates are more common in sloping roofs. The key factors are too loose overlap of the two plates, incomplete self attack, resulting in gap, etc. During the construction of light steel flat roof, roof tile leakage is also a common situation. In rainy seasons, especially when the rainfall is relatively large, the splash of precipitation will produce large-scale water leakage according to the gap between the two color steel plates under the roof.
