Henan Worthwill Industry Co., Ltd. manufactures color coated aluminum coil and sheet for architectural, industrial and OEM production. The aluminum substrate is cleaned, pretreated, roller coated and oven cured on a continuous coating line, giving buyers consistent color, controlled gloss, reliable coating adhesion and good forming performance.
Our prepainted aluminum is available with PE, HDP and PVDF coating systems in common alloys including 1050, 1060, 1100, 3003, 3004, 3005, 3105, 5005 and 5052. We supply coil, cut-to-length sheet and slit strip in RAL colors, metallic colors and colors matched to an approved physical sample. Standard production covers 0.20–5.00 mm thickness and widths from 30 mm up to 1800 mm, subject to alloy, temper and coating system.
Color coated aluminum, also called prepainted aluminum, painted aluminum, prefinished aluminum or colour coated aluminium, is aluminum coil or sheet finished with one or more liquid coating layers before it is formed into the final product. A typical system includes surface pretreatment, primer, topcoat and a protective back coat.
Compared with painting individual parts after fabrication, continuous coil coating provides more uniform film thickness, color and gloss across large production batches. The finished material can then be roll formed, bent, stamped, cut, laminated or assembled into roofing, cladding, ceiling, panel and equipment components.
1. Topcoat: Provides the required color, gloss, weather resistance and surface appearance.
2. Primer: Supports coating adhesion and corrosion protection according to the selected paint system.
3. Pretreatment: Prepares the aluminum surface for stable coating performance.
4. Aluminum substrate: Selected by alloy, temper, thickness and forming requirement.
5. Reverse side: Receives pretreatment and a protective back coat, or a second decorative coating when required.
The exact coating structure should be selected according to the forming process, outdoor exposure, corrosion environment, expected appearance and service requirements of the finished product.
Coils are suitable for continuous production lines, roll forming, corrugating, profiling, lamination and high-volume fabrication. Coil width, inside diameter, outside diameter and coil weight can be matched to the buyer's handling and processing equipment.
Cut-to-length painted aluminum sheets are supplied for CNC cutting, bending, stamping, panel production, signage and general fabrication. Custom sheet lengths, protective film and pallet packing are available.
Slit color coated aluminum strip is available for gutters, shutters, trims, ceiling systems, channel components, lighting parts and other narrow-width applications. Slit width and edge condition should be confirmed before production.
The front side can receive the specified decorative coating while the reverse side is protected by a back coat. Two-side color coating is also available when both surfaces remain visible or require functional protection.
PE polyester: Offers a broad color range, good formability and economical cost. It is commonly selected for interior ceilings, signage, appliance parts, general wall panels and products used in moderate exposure conditions.
HDP high-durability polyester: Provides better weathering and color retention than standard PE. It is suitable for roofing, wall systems, industrial buildings and projects that require an upgraded polyester coating.
PVDF fluorocarbon: Provides strong UV, weather and chemical resistance with stable exterior appearance. It is generally recommended for facades, curtain walls, roofing, coastal projects, high-UV regions and other demanding outdoor applications.
Protective back coat: Supports reverse-side protection, adhesion or compatibility with panel bonding systems. It is commonly used for laminated panels, insulation panels, honeycomb panels and selected industrial applications.
Coating life is not determined by the resin name alone. Film thickness, paint formulation, pigment, gloss, substrate preparation, installation method, local climate, pollution and maintenance all affect actual performance. For outdoor projects, send us the project location and expected service environment so the coating system can be selected correctly.
For more focused information, see our PE coated aluminum coil and sheet and PVDF coated aluminum coil and sheet pages.
1050 / 1060 / 1100: High formability, good corrosion resistance and economical processing. Common uses include lighting parts, signs, trims, ceilings, decorative panels and general forming.
3003: A practical balance of formability, strength and corrosion resistance for roofing, wall panels, ceilings, cladding and insulation systems.
3004 / 3005 / 3105: Higher strength than common 1000-series grades with good roll-forming performance. These alloys are widely used for roofing profiles, gutters, shutters, downpipes, siding and other building components.
5005: Good decorative appearance and moderate strength for architectural panels, facade components, signage and interior decoration.
5052: Higher strength and corrosion resistance for transportation panels, industrial housings, marine-related parts and structural decorative components.
The correct alloy depends on required strength, temper, bend radius, drawing depth, welding method, panel design and service environment. Buyers should not choose an alloy by color or price alone. Learn more about 1100 aluminum, 3003 aluminum, 3004 aluminum and 5052 aluminum.

Standards: Base aluminum can be supplied to agreed ASTM, EN or GB/T requirements when specified in the order.
All values should be confirmed in the final technical specification. Very wide, thick, narrow or special-temper products may have different production limits.
Worthwill supplies common RAL colors such as white, black, gray, blue, red, green, cream and brown, together with metallic silver, champagne, bronze and other decorative colors. Custom matching can be developed from a physical metal sample, coated panel or confirmed color standard.
For repeat orders, the approved color sample should remain the reference. Digital screens and printed color cards can be used for initial selection, but they are not a reliable final standard because screen brightness, printing and lighting conditions change the appearance of color and gloss.
Available visual effects include smooth solid colors, matte finishes, high-gloss finishes, metallic colors, embossed surfaces and printed wood grain or stone grain patterns. Patterned projects should be confirmed separately because pattern repeat, base color, gloss and coating structure affect the final appearance.
Color coated aluminum coil is used for roofing sheets, corrugated panels, standing-seam systems, gutters, downpipes, flashing, shutters and exterior wall components. Aluminum's low weight helps reduce handling and structural load, while the selected coating provides the required color and environmental protection.
PVDF and HDP coated aluminum are widely specified for facade panels, curtain wall components, aluminum composite panels, aluminum honeycomb panels and insulation sandwich panels. Flatness, color consistency, coating adhesion and formability are especially important for these applications.
PE coated aluminum sheet and coil are commonly processed into suspended ceilings, baffles, wall panels, partitions, decorative trims, cabinet surfaces and display systems. Buyers can select matte, gloss, metallic or patterned finishes to match the design.
Painted aluminum can be formed into refrigerator and air-conditioner components, equipment housings, ventilation parts, lighting reflectors and decorative covers. The alloy, coating and reverse-side treatment should be matched to forming, heat and moisture conditions.
Color coated aluminum sheet is used for signs, display panels, trailer and vehicle components, equipment covers, cold-room panels and general industrial enclosures. Protective film can be added when the surface must remain clean during cutting, bending and assembly.

Step 6 — Oven curing: Cure the coating under controlled line conditions.
Step 7 — Inspection and testing: Check appearance, color, gloss, film thickness, adhesion and dimensions according to the approved specification.
Step 8 — Slitting, cutting and packing: Process the material into coil, strip or sheet and apply the agreed surface protection and export packing.
Typical inspection items can include base aluminum alloy, temper and dimensions; surface cleanliness and appearance; coating film thickness; color difference against the approved sample; gloss; cross-cut adhesion; T-bend or forming performance; pencil hardness; impact resistance; solvent resistance such as an MEK rub test when specified; coil edge; sheet flatness; surface protection; packing; labels; and traceability information.
Test methods and acceptance values must be agreed before production. A test name alone is not enough; the contract should state the standard, test condition and pass requirement.
1. Product form: Coil, sheet or strip.
2. Base metal: Alloy and temper.
3. Dimensions: Thickness, width and sheet length if applicable.
4. Coating: PE, HDP, PVDF or another specified system.
5. Color: RAL code or physical color sample.
6. Appearance: Gloss and surface finish.
7. Coating sides: One-side, back coat or two-side coating.
8. Technical requirement: Coating thickness, test standard or project specification.
9. End use: Final application, forming method and installation environment.

11. Coil details: Inside diameter and maximum coil weight.
12. Commercial details: Quantity, destination port and required delivery schedule.
When the final application is known, we can help check whether the requested alloy, temper and coating are suitable before production.
Color coated aluminum coils are normally protected with moisture-resistant wrapping, edge protectors and strong steel or plastic strapping, then secured on suitable wooden or metal pallets. Sheets can be packed with protective film, interleaving paper, waterproof wrapping, corner protection and reinforced export pallets.
Packing is adjusted according to coil weight, sheet size, container loading method, destination and handling equipment. Special marks, labels and inspection photos can be provided according to the purchase contract.
PE is economical, easy to process and suitable for many interior and moderate-exposure applications. PVDF is normally selected for demanding exterior projects where UV resistance, weatherability and long-term appearance are more important. HDP provides an intermediate option for projects requiring better weathering than standard PE.
3003, 3004, 3005 and 3105 are common choices because they combine corrosion resistance, formability and useful strength. The final grade and temper should match the roofing profile, span, forming equipment and local design requirements.
Yes. We can work from a RAL code or develop a color from an approved physical sample. A physical coated metal sample is the preferred reference for repeat orders because it shows both color and gloss.
Yes. The material can be supplied with a decorative front coat and protective back coat, or with color coating on both sides. The two sides may use the same or different systems depending on the application.
A suitable coil-coated system is designed to be formed, but performance depends on alloy, temper, coating flexibility, film thickness, bend radius, tooling and processing conditions. Tell us the forming method so the specification can be checked before production.
Yes. We supply color coated aluminum coil, slit strip and cut-to-length sheet. Sheet length, protective film, pallet type and quantity per package can be customized.
Samples can be provided for qualified projects. For custom colors, sampling time depends on whether an existing paint is available or a new color must be developed.
Production is checked against the approved reference sample. For projects requiring multiple deliveries, buyers should confirm the color standard, gloss and acceptable tolerance before the first order and keep the approved sample for later batches.
No. Coil-coated aluminum is normally finished with liquid paint on a continuous line before fabrication. Powder coating is commonly applied as a dry powder to individual parts and then cured. Anodizing creates a controlled oxide layer by an electrochemical process. Each finish has different appearance, forming and performance characteristics.
The main factors are aluminum alloy, temper, thickness, width, coating resin, coating thickness, pigment, gloss, color-matching requirement, order quantity, coil weight, processing, packing and current aluminum and paint costs.
Send us your application, alloy, temper, dimensions, coating system, color, gloss and quantity. Worthwill Aluminum will review the specification and provide a practical material recommendation, sample plan and quotation for your project.
