Storage of metal siding panels

Metal siding panels, in spite of the double protection of galvanized layer and organic coating on the surface of the steel plate, if it is in a humid state for a long time, the water accumulated on the surface (including water generated by condensation in the air) will gradually penetrate through the organic coating, which will cause the corrosion of the zinc layer under the film of the organic coating, and therefore attention must be paid to it when it is in storage:

1. Metal siding panels should not be soaked by water, should be stored indoors, avoid stacking in the open air.
2. The room should be dry and ventilated, without corrosive gases, and must be avoided in places where condensation is prone to occur and the temperature difference between cold and warm changes greatly. If the metal siding panels have to be temporarily stored outdoors, there must be square sleepers at the bottom as backers, and pay attention to good ventilation. Choose a flat ground, and the top of the backers should also be level, so that the steel plates can be stacked at the same height to prevent warping , The metal siding panels should be covered with a rainproof cloth to protect the product from direct sunlight and rain.
3. Metal should be kept in the state of delivery as far as possible, and should not be piled up, so as not to damage the coating.
4. Metal siding panels should not be placed in sandy and dusty places. If sand and dust accumulate on the steel plate, the coating film of the coated steel plate may be damaged. Moreover, the accumulation of sand and dust will make the surface of the coating difficult to keep dry and become the source of corrosion.
5. In order to eliminate the moisture that stays on the surface of the steel plate in the plate bag for some reason, the steel plate can be placed at an angle in the warehouse, and the suitable angle of inclination is 3.5 degrees.
6. If the metal siding panels are exposed to rain or condensation, they should be unpacked and dried quickly to remove moisture and used as soon as possible.
7. Long-term storage should be avoided, and the principle of advanced use should be used when using, so as to avoid pollution, bruises caused by long-term storage, and slight color differences when new and old products are mixed, especially in coastal and industrial environments. The storage period should be shortened.

When storing metal siding, we must pay attention to protection, prevent moisture and water erosion, pay attention to ventilation, and install it as soon as possible.
