Henan Worthwill Industry Co., Ltd. supplies PE coated aluminum coil, sheet and slit strip for manufacturers that need a clean decorative finish, reliable forming performance and a practical material cost. The polyester coating is applied to prepared aluminum by continuous roller coating and controlled oven curing, helping maintain consistent color, gloss and coating coverage across production batches.
Our PE polyester coated aluminum is commonly used for suspended ceilings, aluminum composite panel skins, signs, appliance panels, interior wall systems, decorative trims, lighting components and general industrial fabrication. Buyers can select common aluminum alloys, RAL colors, custom color matching, different gloss levels, protective back coats and one-side or two-side coating structures.
PE coated aluminum is aluminum coil or sheet finished with a polyester paint system before the material is cut, bent, roll formed, stamped or laminated into the final component. It is also described as polyester coated aluminum, PE prepainted aluminum, polyester painted aluminum or PE color coated aluminum.
Important terminology: On this page, PE means polyester coating used in the metal coil-coating industry. It does not mean the polyethylene film or polyethylene layer sometimes used on coated packaging foil. Making this distinction is important when confirming the paint system, technical data and intended application.
A typical PE coated aluminum structure includes aluminum substrate, surface pretreatment, primer where required, a polyester topcoat and a protective reverse-side coating. The exact coating structure should be selected according to the forming operation, installation environment, color requirement and expected service conditions.
Practical cost-performance balance: Standard polyester is normally more economical than high-durability polyester or PVDF, making it suitable for regular production orders where extreme exterior weather resistance is not required.
Broad color and gloss range: PE coatings can be produced in common RAL colors, custom matched colors, metallic shades, matte finishes, low-gloss finishes and glossy decorative surfaces.
Good forming performance: A correctly specified PE coating can remain adherent during common cutting, bending, roll forming, stamping and panel-lamination processes.
Consistent batch appearance: Continuous coil coating provides controlled coating application before fabrication, supporting more uniform color, film thickness and gloss than painting individual finished parts one by one.
Suitable for many interior products: Standard PE coated aluminum is widely selected for ceilings, signs, partitions, appliance components, decorative covers and other products used indoors or under moderate exposure conditions.
Coil is suitable for continuous production, roll forming, profiling, corrugating, laminating and high-volume manufacturing. Coil width, coil weight, inside diameter and outside diameter can be discussed according to the customer's handling and processing equipment.
Cut-to-length PE coated aluminum sheet is available for CNC cutting, bending, stamping, signage, ceiling panels, equipment covers and general fabrication. Custom sheet length and protective surface film can be supplied when required.
Narrow slit coil is used for ceiling components, trims, shutters, lighting parts, rainwater-system components and other continuous profiles. Slit width, tolerance, edge condition and coil size should be confirmed before production.
The visible face can receive the specified PE decorative coating while the reverse side receives a protective back coat. A decorative coating can also be applied to both sides when both surfaces are visible or require similar protection.
Worthwill supplies PE coated aluminum in common alloys including 1050, 1060, 1100, 3003, 3004, 3005, 3105, 5005 and 5052. Available tempers depend on the selected alloy and forming requirement.
Standard production covers aluminum thicknesses from 0.20 to 5.00 mm and widths from 30 to 1800 mm, subject to the alloy, temper, coating structure and production route. Coil, cut-to-length sheet and slit strip are available.
For standard PE systems, the combined front coating is commonly around 20–25 μm. Worthwill can also discuss coating structures within an approximate 16–35 μm range when required by the product, forming operation or approved technical specification. The primer, topcoat and back-coat requirements should be confirmed separately rather than relying only on a total film-thickness figure.
Colors can be selected from RAL references or matched to an approved physical sample. Matte, low-gloss, medium-gloss, high-gloss and selected metallic finishes are available subject to paint formulation and order quantity.
1050, 1060 and 1100: These alloys offer good formability and economical processing. They are commonly selected for signs, ceiling components, decorative panels, lighting parts, trims and products requiring relatively easy forming.
3003: This alloy provides a useful balance of formability, corrosion resistance and strength for ceiling panels, wall panels, roofing components, equipment covers and general building products.
3004, 3005 and 3105: These grades provide higher strength than common 1000-series alloys while retaining suitable roll-forming performance. Typical uses include gutters, downpipes, shutters, roofing profiles, siding and other formed building components.
5005 and 5052: These alloys are considered when higher strength, improved surface requirements or more demanding fabrication is needed. The final alloy and temper must be matched to the forming process and end-use environment.
The alloy should not be selected by product name alone. Bending radius, profile depth, required strength, surface appearance, corrosion environment and downstream processing all affect the correct choice.
PE coated aluminum coil and sheet are widely used for suspended ceilings, baffle ceilings, wall panels, partitions, decorative trims, cabinet surfaces and display systems. Polyester offers the color choice and forming performance needed for many indoor architectural products without the cost of an exterior-grade PVDF system.
PE coated aluminum can be used as a facing material for aluminum composite panels, insulation panels and selected honeycomb panels. The reverse-side coating must be compatible with the adhesive, foam or lamination system used by the panel manufacturer.
The smooth painted surface, wide color range and ease of fabrication make PE painted aluminum suitable for sign panels, advertising boards, display systems, shop decoration and printed substrates. The required printing, laminating or adhesive performance should be confirmed before ordering.
Polyester coated aluminum is used for equipment housings, refrigerator and air-conditioner components, ventilation parts, lighting covers and decorative appliance panels. Paint formulation and back-coat selection should match the expected heat, moisture, forming and cleaning conditions.
PE coated aluminum can be used for roofing profiles, shutters, gutters, downpipes and wall components in suitable environments. For strong UV exposure, coastal conditions, industrial pollution or projects requiring longer exterior color retention, HDP or PVDF should be evaluated instead of automatically selecting standard PE.
Coils and sheets can be processed into machinery covers, storage-system components, cold-room panels, transportation interior parts and other OEM products. Buyers should provide forming drawings or samples when the coating will undergo severe bending, stamping or profiling.
| Coating System | Main Advantages | Typical Applications | Selection Guidance |
|---|---|---|---|
| Standard PE Polyester | Economical cost, broad color range, good appearance and useful formability | Interior ceilings, signage, appliance parts, decorative panels and general fabrication | Best for indoor or moderate service conditions where extreme exterior durability is not required |
| HDP High-Durability Polyester | Improved UV resistance and exterior durability compared with standard PE | Roofing, wall systems, industrial buildings and upgraded exterior products | An intermediate option between standard PE and PVDF |
| PVDF Fluorocarbon | Strong UV resistance, weatherability and long-term color and gloss retention | Facades, curtain walls, coastal projects and demanding exterior architecture | Recommended for severe or long-term exterior exposure |
Coating performance is not determined by the resin name alone. Pigment type, paint formulation, coating thickness, pretreatment, primer, gloss, color, forming method, installation quality, climate, pollution and maintenance all influence actual service performance.
For a broader comparison, see our color coated aluminum coil and sheet page. For demanding exterior projects, review our PVDF coated aluminum coil and sheet.
Worthwill can produce common RAL colors such as white, silver gray, dark gray, black, blue, red and beige, together with metallic silver, champagne and other project colors.
For custom colors, the most reliable approval reference is a physical color sample. Computer screens, photographs, printed color cards and online RAL charts may show different color, gloss and metallic effects under different lighting conditions.
For projects requiring several production batches, buyers should confirm the complete quantity and retain an approved master sample. Small color differences may occur when orders are produced from separate paint batches or at widely separated times.
