Product Introduction:
Color coated plate, also known as color steel plate or color plate in the industry. Color coated steel plate is a product made by using cold-rolled steel plate and galvanized steel plate as substrates, undergoing surface pretreatment (degreasing, cleaning, chemical conversion treatment), continuously coating (roller coating method), baking and cooling. Coated steel plates have lightweight, beautiful and good corrosion resistance, and can be directly processed. They provide a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc. They have played a good role in replacing wood with steel, efficient construction, energy conservation, and pollution prevention.

Production process:
The main production processes of the common two coating and two drying continuous color coating unit are:

Uncoiler – Sewing machine – Pressure roller – Tensioning machine – Uncoiling loop – Alkali washing and degreasing – Cleaning – Drying – Passivation – Drying – Initial coating – Initial coating drying – Top coat fine coating – Top coat drying – Air cooling cooling – Winding loop – Winding machine – (Lower coil packaged and stored).
Product Usage:
A color coated steel plate using galvanized steel plate as the substrate, in addition to zinc protection, has an organic coating on the zinc layer that serves as a covering and isolation function, preventing rust on the steel plate. Its service life is longer than that of galvanized steel plate, and it is reported that the service life of coated steel plate is 50% longer than that of galvanized steel plate. However, in different regions and usage areas, the service life of color coated panels with the same amount of galvanizing, same coating, and same coating thickness will vary greatly. For example, in industrial or coastal areas, due to the action of sulfur dioxide gas or salt in the air, the corrosion rate accelerates and the service life is affected. In the rainy season, coatings that are soaked in rainwater for a long time or prone to condensation in areas with large temperature differences between day and night will corrode quickly, and their service life will be reduced. Buildings or factories made of colored coated steel plates often have a longer service life when washed by rainwater. Otherwise, their use may be affected by the effects of sulfur dioxide gas, salt, and dust. Therefore, in design, the greater the inclination of the roof, the less likely it is to accumulate dust and other pollutants, and the longer its service life; For areas or parts that are not frequently washed by rainwater, they should be regularly rinsed with water.

Color steel plates are widely used. Has excellent weather resistance, corrosion resistance, high processing and other characteristics. Color steel plates are widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical, automotive industry, and so on.
Quality characteristics:
1. Economy
The production process of color coated steel plates poses less environmental harm and can be recycled, greatly reducing environmental pollution. Moreover, they have a lighter weight and can save materials for load-bearing structures, reducing costs.
2. Easy processing and construction

Color coated panels can be rolled into various shapes and lengths of profiled steel plates as needed, with no overlap in the middle, simple construction, and good waterproof effect.
