Laminated steel plates are often used in industrial construction and agricultural fields, and their anti-corrosion effect mainly depends on the selection of film materials and construction quality.
Laminated steel sheets are generally covered with materials such as polyester film, polyvinyl chloride film or polyester double-coated film. These films have good waterproof, dustproof, weather resistance and chemical corrosion resistance, can isolate the corrosion of steel plates from humidity, oxygen, salt spray, etc. in the atmosphere, and reduce the corrosion rate of steel plates.
The anti-corrosion effect of the coated steel plate also depends on the construction quality. During the construction process, it is necessary to ensure that the bonding between the membrane material and the steel plate is firm without voids or air bubbles. At the same time, the seams of the membrane materials must be properly handled to ensure that the anti-corrosion performance of the seams is consistent with that of the membrane surface to avoid the coating from falling off or cracking.
Generally speaking, the coated steel plate has a good anti-corrosion effect under appropriate construction conditions. However, after long-term use, the membrane material may be aged, damaged or cracked by the impact of external forces, thereby reducing the anti-corrosion ability. Therefore, regular inspection and maintenance are important measures to maintain the anti-corrosion effect of coated steel plates.
