PVDF Kynar 500 Coated PPGI Steel Coil Architectural Facade Curtain Wall 0.5-1.0mm AZ150

PVDF Kynar 500 Coated PPGI Steel Coil is a high-end architectural pre-painted steel coil designed for building facades, curtain walls and prestige architectural cladding. The substrate is a 55 percent aluminium-zinc galvalume steel carrying an AZ150 coating for outstanding corrosion resistance, and the surface is finished with a 70 percent PVDF (polyvinylidene fluoride) resin coating based on Kynar 500. This premium fluoropolymer coating delivers exceptional resistance to ultraviolet light, colour fading, chalking and weathering, which is why it is the standard choice for landmark buildings that must keep their appearance for decades.

The PVDF coating system retains its gloss and colour far longer than polyester or silicone modified polyester coatings, and it resists airborne pollution, acid rain and coastal salt. With a properly applied PVDF finish, architects and developers can expect colour and gloss retention over a service life of 15 to 20 years or more. The coil is formable and can be roll formed, bent and profiled into standing seam roofs, cassette panels and curtain wall sheets, giving designers both performance and freedom of form and colour.

• PVDF Kynar 500 Coating: A 70 percent PVDF fluoropolymer topcoat based on Kynar 500 delivers superior UV, colour fade and chalking resistance for architectural facades.
• Architectural Facade and Curtain Wall: Specified for high-end building facades, curtain walls, standing seam roofs and prestige cladding where long life appearance is essential.
• Excellent Weather Resistance: The fluoropolymer coating resists UV light, acid rain, pollution and temperature extremes, retaining colour and gloss for 15 to 20 years or more.
• Galvalume AZ150 Substrate: A 55 percent aluminium-zinc coating provides markedly better corrosion protection than plain zinc, especially in coastal and industrial environments.
• Formable and Fabricable: The coil can be roll formed, bent and profiled into standing seam and cassette panels without cracking the premium coating.
• Certified and Traceable: Produced under ISO 9001 management with SGS inspection and a mill test certificate covering coating weight, thickness and coating performance.

PVDF Kynar 500 coated PPGI steel coil is used for high-end architectural facades, curtain wall panels, standing seam roofing, metal wall cladding and roof cassettes on commercial buildings, airports, stadiums, exhibition centres and landmark towers. It is also used for aluminium composite style cladding, canopies, column covers and other exterior architectural elements where long-term colour stability and low maintenance are required. Its combination of premium appearance, weather resistance and long service life makes it a preferred material for architects and developers worldwide.

Q: What is PVDF Kynar 500 coated steel coil?
A: It is a pre-painted steel coil finished with a 70 percent PVDF fluoropolymer coating based on Kynar 500 resin, giving outstanding UV, colour fade and weathering resistance for architectural use.

Q: How long does PVDF coating last on a facade?
A: With proper application, PVDF Kynar 500 coatings retain colour and gloss for 15 to 20 years or more, far longer than standard polyester coatings.

Q: What is the difference between PVDF and PE coating?
A: PVDF uses fluoropolymer resin for superior UV and fade resistance and a longer life, while PE polyester is more economical and suited to general roofing and light cladding.

Q: Can PVDF PPGI be used for coastal buildings?
A: Yes. Combined with an AZ150 galvalume substrate, the PVDF system resists coastal salt and pollution, making it ideal for high-end coastal architecture.

Each coil is wrapped with PE film and waterproof paper, secured with steel strapping and loaded onto fumigated wooden pallets for ocean transport. Every coil is labelled with substrate, coating weight, colour, thickness, coil number and weight for full traceability. We supply mill test certificates, coating performance data, SGS inspection reports and pre-shipment photographs on request, and our ISO 9001 certified process ensures consistent premium quality. Colour samples and coating warranty documentation are available for project approval.
