Product Description
Color coated plate, also known as color steel plate or color plate in the industry. Color coated steel plate is a product made from cold-rolled and galvanized steel plates, which undergo surface pretreatment (degreasing, cleaning, chemical conversion treatment), continuous coating (roller coating method), baking, and cooling. Coated steel plates have lightweight, aesthetic, 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, and other industries, playing a good role in replacing wood with steel, efficient construction, energy conservation, and pollution prevention.
The basic concept of color coated steel plate is to use cold rolled strip steel and galvanized strip steel (electro galvanizing and hot galvanizing) as substrates on a continuous production line, undergo surface pretreatment (degreasing and chemical treatment), apply one or more layers of liquid coating by roller coating method, and then bake and cool to obtain the coated steel plate. There are back (bottom) paint and top (front) paint coatings in China. Generally, there is one layer of back paint and two layers of top paint in China, while the back paint for foreign business is two layers. Due to the fact that coatings can come in various colors, it is customary to refer to coated steel plates as colored coated steel plates.
The color coated steel plate using galvanized steel plate as the substrate, in addition to zinc protection, the organic coating on the zinc layer plays a covering and isolation role, which can prevent the steel plate from rusting and has a longer service life than galvanized steel plate. 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 zinc plating, same coating, and same coating thickness will vary greatly. For example, in industrial areas 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.
During the rainy season, coatings that are soaked in rainwater for a long time or are prone to condensation in areas with large temperature differences between day and night will quickly corrode and have a reduced service life. 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, if the inclination of the roof is greater, it is less likely to accumulate dust and other pollutants, and the service life is longer; For areas or parts that are not frequently washed by rainwater, regular water flushing should be carried out.
Color steel plates are widely used. It has characteristics such as pollution-free, excellent weather resistance, corrosion resistance, and high processing efficiency. Color steel plates are widely used in construction, home appliances, transportation, packaging, mechanical processing, interior decoration, medical treatment, automotive industry, and so on..
Part 1 The benefits of using corrugated steel sheets in your projects
- Highly robust
- Light weight
- Weather and corrosion resistant
- Excellent quality of protection
- Easy to install
Part 2 Complete your galvanized corrugated metal.
Corrugated steel roof sheets are galvanized to provide a highly corrosion-resistant surface, so no further painting or other surface treatments are required to improve the
for extra protection. However, for aesthetic purposes, galvanized products can be painted or powder coated if desired.
Galvanized Corrugated Steel Plate is pressed from galvanized or galvalume coils and can be produced in different tile shapes as required.
Part3 Substrate Types
1. Galvalume steel substrates
Excellent corrosion resistance, suitable for the production of exterior building panels and can be processed at various levels such as general forming and mechanical nibbling.
2. Hot-dip galvanized substrate with excellent corrosion resistance.
Suitable for the production of exterior architectural panels, which can be processed at various levels such as general forming, stamping and deep stamping.
3. Electro-galvanized substrate
Good corrosion resistance, thin zinc layer, good processing properties. Suitable for the manufacture of household appliances, steel windows or interior partitions.Corrugated galvanized metal is ideal for wet areas because the material will not rust even after years of water spraying.Galvanized steel for long-term outdoor use should be hot-dip galvanized; it typically lasts about 70 years in many different environments.
Part 4 Choose us
Galvanized steel is a common material for outdoor furniture because it is durable and rust-resistant. Choosing outdoor furniture made of galvanized steel construction will help ensure that your piece will remain intact under external conditions.
