Bis Certificat Dx51d ASTM Ral3005 6005 3013 9016 5015 914mm 1219mm Cold Rolled Color Coated Prepainted Coils

Generally, the coating of color coated steel sheets is non-conductive polymer, while the anti-static color coated steel sheets contain conductive materials in the non-conductive coating, turning the coating into a semiconductor. When a steel sheet is installed, it is connected to the ground wire, which can eliminate the static electricity generated by air convection and clothing friction on the surface of the steel sheet grounded.

They are suitable for electronic machinery, parts, computers, semiconductors, pharmaceutical manufacturing, dust-free and sterilized operating rooms, film manufacturing, biochemical technology, food, combustible gas, organic solvents, coating chemicals and other workplaces that require an antistatic and high cleanliness environment. They are against the damage to electronic components and semiconductors or the adsorption of dust and bacteria caused by electrostatic deposition on the surface of the steel sheets.

It is easy to rust when the air and water go through the organic coating, and it is easy to spread after scratches and cause the coating to peel off. So it has a short service life. But it will be much cheaper.

Color Coated Galvanized Coil (PPGI Coil)

It uses galvanized steel as base metal, including hot-dip galvanized sheets and electro-galvanized sheets. It is the most popular type of color coated steel, especially using hot-dip galvanized steel as the base material. This kind of steel coil is protected by zinc layer and organic coatings to prevent rusting. Because the zinc layer of the electro-galvanized sheet is thin, it is not suitable for outdoor uses. But because of its smooth surface and beautiful appearance, it is popular in interior decoration, steel furniture, home appliances, etc.

Colour Coated Galvalume Coil (PPGL Coil)

Obviously, this kind of color coated steel coil uses galvalume steel as the substrate. It features excellent corrosion and heat resistance. And its heat reflectivity is greater than 0.75, which is an ideal building material.

When purchasing color coated coil, you need to decide on the base metal first according to the use purpose and your budget. You can contact us for more details.

Tips for Buying Color Coated Steel Coil

1 . Confirm the base metal, mainly including GI and GL, as well as the zinc or Al-Zn coating thickness; cold rolled color coated steel is not recommended.

2 . Choose the coating types and the coating thickness, generally 10/5 μm (top/back). The common paints are PE (7-8 years service life), SMP (10-12 years), HDP (15+ years), PVDF (20+ years); And the top and back paints can be different. Moreover, we commonly adopt twice painting for double sides. If you have special requirements, please let us know.

3 . Determine the color or pattern, surface (smooth or embossed, matte or glossy, etc.), specifications (including width, length, thickness, coil weight, etc.);

4 . Inform us of the order quantity. The MOQ is 5 tons. But considering the shipping cost, 25 tons (a full container) will be better.

5 . Please leave us your other requirements, such as packaging, samples, surface treatment (such as oiling, passivation, etc.), and more.

6 . It is available to visit our factory and office online or on-site. Also, we will offer free samples if you need them.
