PVDF Coated Aluminum Sheet 1.0-4.0mm Thickness 1500mm Width Color Coated Aluminum Sheet for Curtain Wall Facade Cladding

This PVDF coated 3003 aluminum sheet is a factory-finished cladding material built for exterior architecture. The substrate is AA3003 aluminium-manganese alloy, rolled to 1.0–4.0 mm and supplied in H14 or H24 temper so that fabricators can shear, route, fold and roll it without spring-back problems.

Both faces receive a polyvinylidene fluoride coating system based on Kynar 500 resin, applied as two coats and baked three times, which gives a dry film thickness of 25 micron or more and locks the pigment into a fluorocarbon matrix. That matrix is what keeps a building looking new: the surface resists ultraviolet degradation, acid rain, salt fog and industrial pollution far better than polyester or powder coatings, and it holds gloss and color within a Delta E of 2 after years of outdoor exposure.

Because the coil is coated before forming, every panel of a project arrives with identical color, and touch-up is limited to cut edges. The sheet is used for solid aluminium cladding, aluminum composite panels, column covers, fascia, soffits and rain-screen systems, and it is equally suited to coastal and high-humidity regions where ordinary coated steel would chalk or rust within a few seasons.

• Fluorocarbon Weathering: Kynar 500 based PVDF resin keeps color and gloss stable under UV, acid rain and salt fog, backed by a 20-year exterior performance warranty.
• Formable 3003 Core: Aluminium-manganese substrate in H14 or H24 temper bends, rolls and folds cleanly around tight radii without cracking the coating film.
• Three-Bake Coating Line: Two coats and three oven passes produce a dense 25 micron film with consistent hue, hiding power and inter-coat adhesion.
• Tight Gauge Control: Thickness is held within ±0.02 mm across the full coil so folding dimensions and panel flatness stay predictable.
• Surface Protection: A removable PE protective film is applied to the finish side and edge protection is fitted to every bundle for container transit.
• Broad Color Program: Standard RAL and Pantone shades are stocked, and custom color matching is available from 3 tons per shade.

Architectural cladding is the primary duty of this material. It serves as solid aluminium facade panels, skins for aluminum composite panels, column and beam covers, window surrounds, louvre frames and concealed-fix rain screens on offices, hospitals, airports, metro stations and shopping centres.

Because the coating survives washing with alkaline cleaners, the sheet is also chosen for petrol station canopies, drive-through fascia and coastal hotels where salt exposure is constant. Sign makers use the same coil for illuminated fascia lettering and pylon cladding, while transport manufacturers convert it into train interior wall panels and bus skirt panels that must pass fire and smoke tests.

Where a project demands a metallic or brushed appearance, the coating line can lay a metallic basecoat under the clear PVDF topcoat so the final panel reads as champagne, titanium or copper without any post-finishing step.

Each coil is interleaved with kraft paper, wrapped in PE film, edge-protected and packed in a plywood crate sized for forklift handling; a 20GP container carries roughly 22 metric tons.

Every batch is tested for film thickness, gloss, adhesion, pencil hardness, impact and 1000-hour salt spray before shipment, and a mill test certificate together with a color chip is issued with the shipping documents. If a panel is damaged on site, we supply matching touch-up paint and can produce replacement sheets from the same coating batch within 15 days so repairs stay invisible.
