3004 H26 Prepainted Aluminium Coil

 Stable Strength & Good Formability

H26 temper provides balanced rigidity and workability. It supports simple bending, flattening, and shearing for standard parts and panels. It is not recommended for complex deep drawing to avoid cracking, which makes it perfect for mass-production line processing.

 Lightweight & Corrosion Resistant

Aluminum alloy is much lighter than steel, reducing load for buildings and equipment. The material performs well in atmospheric, fresh water, and mild corrosive environments. Combined with a protective color coating, it extends service life and lowers maintenance costs.

 Flexible Coating & Appearance Customization

We use PE, SMP, and PVDF coating systems to match indoor, outdoor, and high-durability demands. Colors follow RAL and Pantone charts. Surface textures include fine pebble, orange peel, and wood grain for architectural and industrial aesthetics.

 Stable Batch Quality & Fast Processing

Roll-to-roll coating ensures uniform thickness and color across the whole coil. It supports high-speed cutting and forming, helping you shorten production cycles and improve finished product consistency.

Need an aluminum sheet that holds up around water without extra coatings? This 3003-grade alloy carries 1.0–1.5% manganese, giving it dependable resistance to atmospheric exposure, fresh water, and mild corrosive conditions. It runs light, transfers heat quickly, and keeps its shape under load: the hard, semi-hard temper delivers tensile and yield strength above standard 3003 H24, so panels resist denting and warping in daily service.

Shop-friendly, too - it bends, cuts, and flattens with ordinary equipment. One honest limit: skip deep punching or complex forming, since aggressive deformation can cause cracking. Keep bend radii generous and it performs reliably.

 Construction field: exterior wall decorative panels, roof panels/aluminum tiles, rain sinks, ceiling keels, suitable for ordinary buildings and factories

 Industrial field: equipment shells, protective plates, storage shelves, simple boxes, rigid but easy-to-process parts

 Other fields: home appliance base/frame, small metal products, outdoor simple facility shell

We operate standardized production lines for prepainted aluminum coils, with the manufacturing process covering raw material inspection, surface pretreatment, roll coating application, curing and cooling, finished product testing, packaging and warehousing. Every batch of incoming raw materials undergoes chemical composition and mechanical property inspections prior to admission. Coating thickness, adhesion strength and color deviation are monitored in real time throughout production, and finished products must pass multiple tests including corrosion resistance and impact resistance before delivery.

Q: Is 3004 H26 suitable for outdoor roofing?

A: Yes. With proper topcoat such as PVDF or SMP, it offers excellent weatherability and corrosion protection for roofing and cladding.

Q: Can you produce according to our samples or drawings?

A: Yes. We accept customization based on your samples, technical drawings, or color codes.

Q: How does this coil compare with galvanized steel coil in similar applications?

A: 3004 H26 prepainted aluminum is lighter, more corrosion-resistant in mild environments, and offers more appearance options. Electro-galvanized steel provides good cost efficiency for indoor and general anti-rust parts but is heavier and has limited surface choices.
