Prepainted Galvanized Steel Coil Benefits

1. Durability: corrosion resistance and galvanized steel sheet compared with longer service life.

2. Heat resistance: compared with galvanized steel sheets at high temperatures less simple fading.

3. Thermal reflectivity: sunlight exposure has a certain reflection performance.

4. Color-coated galvanized steel coil has a similar processing performance and spraying performance to galvanized steel

5. With excellent welding performance.

Applications

1. Construction industry

Used for roofs and walls of factories, warehouses, and greenhouses, with both waterproof and decorative properties; as color steel sandwich panels, used for thermal insulation buildings; interior decoration, such as suspended ceilings and partitions.

2. Home appliances and electronics

Making refrigerators, air conditioners, and other home appliance shells to reduce spraying costs; used for distribution boxes, cabinets, etc., to the advantage of electromagnetic shielding and lightweight.

3. Transportation

Lightweight parts such as automobile linings and luggage racks, ship partitions and container inner walls, are resistant to salt spray corrosion.

4. Furniture and daily necessities

Office furniture (file cabinets, display racks), household items (lampshades, anti-theft door panels) are durable and easy to clean.

5. Industry and others

Billboards, ventilation ducts, and light industrial equipment covers, taking into account both beauty and protection.

Prepainted Galvanized Coil vs. Galvanized Steel Coil

Prepainted galvanized coil and galvanized steel coil are commonly used building materials and have a wide range of applications. They have specific differences in appearance, performance, and use, but they have certain advantages in terms of corrosion resistance, durability, strength, and stability. Details are as follows:

Appearance distinction

Color-coated galvanized coil and galvanized steel coil have great differences in appearance. The surface of the galvanized steel coil presents a bright silver white, while the surface of the color-coated galvanized coil is designed with different colors and patterns. In addition, the surface of the color-coated steel coil is also specially treated to make it have better weather resistance and corrosion resistance.

Functional distinction

There are also some differences in function between color-coated galvanized coil and galvanized steel coil. The galvanized coil is mainly used for anti-corrosion, wear resistance, structural support, etc., and color-coated galvanized coil pays more attention to the aesthetic effect of the external wall of the building and also has a certain anti-corrosion, durability, and fire performance.

Application range difference

The application range of color-coated galvanized coil and galvanized coil is also different. The galvanized coil is suitable for a variety of construction projects, such as building infrastructure, pipeline transportation, and other aspects; The prepainted galvanized coil is more suitable for building exterior walls, roofing, decoration, and other aspects, can meet a variety of architectural styles and design needs.

In summary, there are some differences between color-coated galvanized coil and galvanized coil in appearance, material, function, and application. But they also have many similarities and have certain advantages in terms of corrosion protection, durability, strength, and stability. The selection of the appropriate material needs to consider the actual needs as well as its characteristics and characteristics to meet the requirements of use better.

How To Choose The Type Of Paint for PPGI?

The main function of the coating is reflected in the visual effect and protection function. The pigments of the coating can be divided into organic pigments and inorganic pigments, and the organic pigments are bright in color. Inorganic pigments are generally light colors, but their chemical properties and ultraviolet resistance are better than organic pigments.

Common paint type

The most commonly used paint types of color steel plate are: polyester (PE), silicon modified polyester (SMP), high durability polyester (HDP), and polyvinylidene fluoride (PVDF), each paint to adapt to different situations, in the case of economic permitting we recommend the use of HDP or PVDF products.

Primer and topcoat

For primer selection, the emphasis on adhesion and corrosion resistance should be used epoxy resin; If you are more concerned about flexibility and UV resistance, choose polyurethane primer or polyurethane primer.

For the back coating, if the prepainted galvanized steel coil is used as a single board, choose a two-layer structure, that is, a layer of rear primer and a layer of back finish. If the color-coated steel plate is used as a composite or sandwich board, a layer of epoxy resin on the back can also be used with a two-layer structure with enhanced adhesion.
