彩钢板，尽管在钢板表面有镀锌层和有机涂层的双重保护，但如果长期在潮湿的状态下，表面所积存的水会逐渐渗透通过有机涂层，从而造成有机涂层膜下锌层的腐蚀，因此在储存时必须注意：

Although color steel plates have dual protection of galvanized layer and organic coating on their surface, if they are kept in a humid state for a long time, the accumulated water on the surface will gradually penetrate through the organic coating, causing corrosion of the zinc layer under the organic coating film. Therefore, attention must be paid when storing:

（1）不被水浸湿，存放在室内，避免露天堆放。

(1) Not soaked in water, store indoors and avoid outdoor stacking.

（2）室内应干燥通风，无腐蚀性气体，必须避免放在易发生结露以及冷暖温差变化大的地方。迫不得已暂时存放室外时，底下一定要有方形枕木作垫木，并注意通风良好，选择平坦的地面，垫木上方也要水平，以使钢板堆放在同一高度上，防止发生翘曲，产品上面要盖上防雨布，保护产品不直接受日晒雨淋。

(2) Indoor areas should be dry, ventilated, and free of corrosive gases. They must be avoided from being placed in areas prone to condensation and large temperature differences between cold and warm temperatures. When it is necessary to temporarily store outdoors, there must be square sleepers as padding underneath, and good ventilation should be ensured. A flat ground should be selected, and the top of the padding should also be horizontal to ensure that the steel plates are stacked at the same height to prevent warping. The product should be covered with rainproof cloth to protect it from direct sunlight and rain.

（3）若彩钢板受到雨淋或有了结露，应马上拆包迅速干燥，除去湿气，并尽早使用。

(3) If the color steel plate is exposed to rain or condensation, it should be unpacked and quickly dried to remove moisture, and used as soon as possible.

（4）钢卷应尽量保持出厂时的状态存放，不要堆积，以免损伤涂层。

(4) Steel coils should be stored in their original factory condition as much as possible and should not be stacked to avoid damaging the coating.

（5）彩色涂层钢板不要放在砂土、灰尘多的地方。钢板上面若积存砂土、灰尘，可能损伤涂层钢板的涂膜。且砂土、灰尘的积存，会使涂层表面不容易保持干燥，成为产生腐蚀的根源。

(5) Color coated steel plates should not be placed in sandy or dusty areas. If sand and dust accumulate on the steel plate, it may damage the coating film of the coated steel plate. Moreover, the accumulation of sand and dust can make it difficult for the coating surface to remain dry, becoming the root cause of corrosion.

（6）应避免长期存放，使用时以先用为原则，以免长期留存不用所造成的污染、碰伤，以及新、旧产品混用时出现微小的颜色差异，尤其在沿海及工业气氛的环境中，更应缩短存放期。

(6) Long term storage should be avoided, and the principle of first in, first in use should be followed when using to avoid pollution, scratches caused by long-term retention and use, as well as slight color differences when mixing new and old products. Especially in coastal and industrial environments, the storage period should be shortened.

（7）为了排除因某种原因滞留在板包内钢板表面的水分时，钢板在仓库里可以倾斜放置，适宜的倾斜角度为3.5度。

(7) In order to eliminate the water retention on the surface of the steel plate inside the plate package for some reason, the steel plate can be tilted in the warehouse at an appropriate angle of 3.5 degrees.
