The climax of the architectural era is about to fade away, so the competition for new building materials is becoming more and more fierce. The sandwich color steel plate is also one of the fierce competition. In fact, it is very popular in the field of building, whether it is on the roof, or on the wall, partition, or ceiling, but even if it is widely used, it has many applications Is to comply with the requirements of the construction era, only in this way can we go for a long time.In fact, the requirements for the sandwich color steel plate are as follows: first, it is sometimes limited by the dimensional accuracy of production equipment and assembly houses, so the width tolerance must be controlled within a certain range; second, the thickness should be uniform, when the thickness of the coated steel plate is uneven, it will be "sickle shaped" along the length direction; third, the sandwich color steel plate is not allowed to be oiled Picture wax or miscellaneous dust, and it is strictly prohibited to enter water during storage. The back coating should be the coating with good bonding performance. In fact, these requirements are also for the products of the building. Only in this way can we build the products we need more quickly and safely in the construction of sandwich color steel plate. Therefore, if it wants to develop, it must conform to the requirements of the building era.
