What precautions should be taken during the use of Embossed Pre-painted Aluminium Coil

First, if Embossed Pre-painted Aluminium Coil is to be put into use, it must be under normal temperature, and the temperature should not be too hot or too cold. If it is used as a roof, the height should not be lower than 10 degrees.

Second, before the installation, check in time to ensure that the roofing material has no signs of wear and tear, to ensure that it can be used normally, and to ensure the service life under normal conditions.
Third, the bolt heads for fixing the Embossed Pre-painted Aluminium Coil should be sealed with a strong waterproof material to prevent rainwater from entering and rusting.
Fourth, the ambient temperature of Embossed Pre-painted Aluminium Coil processing should be above 7°C, the gap of the processing roller system should be adjusted according to the thickness of the color-coated aluminum coil, and the foreign matter on the roller surface and the pallet should be removed; at the same time, the color-coated aluminum coil should be checked. Whether the paint on both sides of the roll is peeling off, if the paint is peeling off, the cause should be identified and measures should be taken before continuous processing.

The Embossed Pre-painted Aluminium Coil will bend when it is cooled. The reason is: under the general air-cooling condition, the heat transfer coefficient of each part of the thermal insulation aluminum coil in contact with the air is the same, but because of the different wall thickness or shape, each part has the same heat transfer coefficient. The heat dissipation rate of the heat preservation aluminum coil is not balanced, resulting in the heat dissipation rate of the thick-walled part or the hollow tube being slower than that of the thin-walled part, and finally the heat-insulating aluminum coil will appear to the hollow part when it cools.

Through the above introduction to Embossed Pre-painted Aluminium Coil, we have learned about the state of aluminum coils. Only when we understand the state of relevant aluminum coils can we manufacture items with different characteristics according to aluminum coils in different states.
