Prepainted Sheet Metal

Prepainted sheet metal refers to functional composite materials with organic coating (epoxy, polyester, fluorocarbon, etc.) applied to the metal substrate (steel, aluminum, alloy, etc.) before shipment from the factory. Wanzhi Group is a factory supplier of Pre-coated metal, which is ISO 9001 certified, with mature production lines for galvanizing, painting, bending, etc. We provide one-stop service from raw material to finished product.

Product Catalog

 

Prepainted Metal – Galvanized Steel Sheet

Prepainted GI (Zinc) / GL (55% Al-Zn) is a cost-effective solution for prepainted sheet metal materials for outdoor and industrial applications. It is a cost-effective coating material for steel substrates such as galvanized steel and aluminium zinc plated steel with a salt spray resistance of 500-2000h.

Prepainted Sheet Metal – Aluminum Sheet

Prepainted aluminum sheet is a coated metal material made of pure aluminum or aluminum alloys coated with organic paints. Prepainted metal made of pure aluminum or aluminum alloys is the preferred solution for lightweight metal materials for the construction and electronics industries.

Prepainted Sheet Metal – Magnesium Alloy Sheet

Prepainted magnesium alloy sheet, a colored alloy coated steel with a magnesium alloy substrate, is lighter in weight than aluminum and has an excellent strength-to-weight ratio, but is more costly and less easily processed, and is mainly used in aerospace and other special applications.

Prepainted Sheet Metal – Stainless Steel Plate

Prepainted stainless steel plate, alloy steel based on 304, 316L, 430 stainless steel with colored or special coatings.

Prepainted Sheet Metal – Coating

The coating of prepainted metal consists of a primer, a topcoat and a special coating. The role of primer is to improve the adhesion; the role of topcoat is to enhance the corrosion resistance, weathering, durability, etc.; the role of special coatings is to improve the functionality of the metal, such as fingerprint resistance, UV resistance, antimicrobial resistance, and so on.

Primer Coating

• Epoxy primer: prepainted sheet metal commonly used primer, with excellent corrosion resistance, high durability.
• Polyester primer: one of the most popular primers, low cost, good adhesion.

Topcoats

• Polyester Coat (Polyester Coat): polyester coat painted steel, low cost, wide range of uses, commonly used in general outdoor environments with high demand for appearance.
• Silicone Modified Polyester (SMP): Silicone modified polyester pre-painted metal, better heat resistance and UV resistance.
• Polyvinylidene Fluoride (PVDF): PVDF coated pre-painted metal is a high-end coating with excellent weathering, UV stability and chemical resistance. Used for high-end or exposed architectural applications.
• Polyurethane Coating (Urethane Coating): Polyurethane coated pre-painted metal provides a glossy finish and high abrasion resistance and is typically used in more aesthetic or industrial environments.
• Highly Weatherable Polyester: Highly weatherable polyester coated pre-painted metal, using high molecular weight resins, is resistant to weathering, corrosion and color stability. Used for long term outdoor exposure in architectural and advertising/transportation applications.

Special Coatings

• Anti-fingerprint coatings: coatings that prevent stains, grease and fingerprints from adhering to the surface and keep the surface of the metal material bright and clean.
• Antimicrobial Coatings: Commonly used in hospital/food processing environments to inhibit and reduce the growth of bacteria/mold.
• Scratch Resistant Coatings: Provide an additional layer of abrasion protection for steel to minimize physical wear and tear.
• Heat Resistant Coatings: Coatings that enhance the high temperature resistance of metallic materials.
• Anti-static coatings: Coatings commonly used in the electrical and electronic industries to reduce the build-up of static electricity.
• Acoustic coatings: Specialized coatings to reduce noise, commonly used on building facades and industrial machinery.

Areas of Application and Advantages

Prepainted sheet metal not only play an important role in protecting the metal substrate, but also enhance the appearance and performance of the product, making them widely used in a number of industries.

Applications of Prepainted Sheet Metal

1. Industry and Energy: Factory air ducts, dust removal equipment, photovoltaic racks, wind turbine hulls, greenhouse skeletons, grain bin roofs.
2. Home appliances and electronics: refrigerator, washing machine, air conditioning panels, server chassis, smart home shell, oven, hood liner, cell phones, computer shells
3. Transportation: body panels, truck compartments, public transportation interiors and doors, cabin bulkheads, deck decorations, boat hulls, aircraft shells
4. Architecture and decoration: architectural curtain wall/exterior facade, roofing materials, wall enclosure systems, suspended ceilings, partitions, elevator cabs, traffic signs.

Advantages of Prepainted Sheet Metal

• Variety of colors and textures, metallic/pearlescent effect/printed wood/stone/embossed/printed, etc.
• Prepainted metal coil and sheet made of different materials with a salt spray life of 500~6000 hours.
• Maintenance costs, low processing costs, long-term use of cost-effective.
• Prepainted sheet metal is resistant to ultraviolet rays, high temperature, rain, oil / fingerprints / dust and other stains, air, moisture, salt and other corrosive corrosion.
