Pre-Painted Color Coated Aluminum Sheet 3003 5052 PVDF PE 0.2mm-1.2mm For Roofing Wall Cladding

Pre-painted color coated aluminum sheet starts as 3003 or 5052 strip that is cleaned, chemically pretreated and coated on a continuous coil coating line, where precise rollers lay down a primer, a finish coat and a backer in one pass. The result is a building material with a factory cured paint film that is far more uniform and durable than any site applied painting system. We offer both PVDF resin systems, which carry the famous Kynar type warranty for decades of exterior exposure, and economical polyester or PE systems for interior and less demanding applications. The aluminum substrate guarantees that the panel will never develop the edge rust that destroys painted steel on cut edges and drilled holes.

Because the paint film is applied before forming, coated aluminum sheet can be roll formed into roofing profiles, wall panels and gutter sections without cracking, and the flexibility of the coating survives the tight bends of standing seam machines. Color consistency between coils is monitored with spectrophotometer readings on every production run, so large facades assembled from different deliveries blend seamlessly. Architects value the wide palette that includes metallic finishes, wood grain prints and stone patterns, all of which keep their appearance for years in UV rich climates. Our line cuts master coils into sheets or slit widths to suit each customer forming line, reducing handling damage and waste.

• Factory cured paint system: continuous coil coating gives uniform film thickness, perfect adhesion and consistent color across every meter.
• PVDF durability option: 70 percent PVDF finish resists chalking and fading for decades, backed by long term performance warranties.
• No edge rust on cut surfaces: the aluminum substrate cannot develop red rust, so sheared edges and fastener holes stay clean outdoors.
• Formable after painting: the coating passes zero T bend tests and survives roll forming, press braking and deep drawing without cracking.
• Wide color and finish range: RAL colors, metallic, wood grain and stone prints allow striking architectural combinations.
• Lightweight building envelope: low density panels cut structural steel weight and speed up installation on high rise facades.

Pre-painted color coated aluminum sheet is installed on commercial and residential roofs as standing seam and corrugated profiles, on building facades as concealed fixed cladding and cassette panels, and on canopies, awnings, gutters, downspouts and window trim. Cold storage warehouses use the bright surface for insulated panel facings, while transport and container manufacturers specify the coated sheet for lightweight body panels. Interior designers use the wood grain and metallic finishes for ceiling baffles, column covers and feature walls, and appliance makers use the coil for decorative trims where color consistency between batches is critical.

Coated coils are wound on steel cores with the painted surface outward, protected by edge protectors, kraft paper and a moisture barrier wrap for container shipment. Cut sheets are interleaved with PE film and palletized with corner protection. Every production lot is tested for film thickness, gloss, color difference, pencil hardness, impact resistance, T bend flexibility and salt spray performance before release, and test certificates are provided with the delivery. We keep your color standard on file for repeat orders and can supply bonded samples of the actual production coating for your project approval.
