As a professional painted aluminum sheets exporter integrating R&D, manufacturing, and export, HC Aluminum leverages production capabilities and fully automated coil coating lines to provide reliable, compliant painted aluminum products for global sectors including architectural decoration, home appliance manufacturing, transportation, and cleanroom engineering. HC Aluminum core value lies in factory-controlled quality and export-oriented service, we manage every step—from substrate selection and coating formulation to final delivery—ensuring products meet the specific climatic conditions and industry standards of diverse regional markets.
HC Aluminum offer a comprehensive range of painted aluminum sheet products designed for a wide range of applications. Our core coating systems include Polyester (PE), Fluorocarbon (PVDF) coatings. We primarily utilize 3003-H24, 3105-H24, and 5052-H32 aluminum alloys, with thicknesses ranging from 0.3mm to 3.0mm and a maximum rolling width of 1600mm; products are available in both flat sheet and coil formats.
Our PE coatings feature a top-side dry film thickness of 18–25μm, withstand 1,000 hours of neutral salt spray testing without blistering, and offer 5–10 years of color retention; offering excellent cost-performance, they are widely used in interior decoration, home appliance panels, and standard architectural facades.
Our PVDF fluorocarbon coatings utilize PVDF resin with a fluorine content of ≥70%, featuring a top-side film thickness of 20–28μm; they withstand 3,000 hours of salt spray testing and demonstrate superior durability—with a color difference (ΔE) of ≤0.5 after 4,000 hours of accelerated weathering—and a color retention lifespan of 15–20 years, making them the ideal choice for regions with high temperatures and intense UV radiation.
Comprehensive quality control across the entire manufacturing process ensures long-term performance reliability. HC Aluminum employ a comprehensive "two-coat, two-bake" coil coating process. During pre-treatment, we utilize a chromium-free passivation conversion coating to form a dense, well-bonded layer (0.8–1.2 μm)—the fundamental basis for superior coating adhesion and corrosion resistance. Industry experience shows that many low-priced products on the market cut corners on pre-treatment; while they may look identical initially, issues such as coating peeling or delamination often arise within 3–5 years. HC painted aluminum sheet products achieve an ASTM D3359 Class 0 rating for adhesion, showing no detachment during cross-hatch testing. We maintain strict color consistency within the same batch (ΔE ≤ 0.5) to prevent disputes in bulk supply. With substrate flatness ≤1 mm/m and coating thickness uniformity within ±2 μm, our products are ideal for subsequent bending and stamping; the coating remains intact—free from cracks or peeling—after forming. All products are certified under systems such as AAMA 605.2 and ISO 9001, and third-party test reports are available.
As a factory-direct painted aluminum sheet exporter, HC Aluminum eliminate intermediaries, offering significant cost advantages for comparable quality while supporting flexible customization. We can match full RAL and NCS color ranges or customize colors based on client samples. Value-added services such as slitting, protective film application are available upon request; slitting width tolerance is maintained at ±0.3 mm, and surfaces are covered with PE protective film to prevent transit scratches. Standard specifications can be delivered within 7–12 days, supported by a monthly capacity of 12,000 tons to handle large, stable orders. Our logistics network leverages ports in both Qingdao and Shanghai, supporting trade terms such as FOB, CIF, and EXW, and providing complete customs clearance documentation, including Certificates of Origin, material certificates, and test reports. We offer product selection advice tailored to the client's local climate and application scenarios—such as recommending high-weatherability PVDF systems for the Middle East or enhanced epoxy primer configurations for high-humidity regions in Southeast Asia—ensuring clients receive the most suitable and cost-effective solutions.
HC Aluminum consistently provides global customers with high-value coated aluminum sheet solutions—characterized by stable quality, flexible customization, and efficient delivery—thereby helping them build product competitiveness in their local markets.
