3004 aluminum sheet belongs to the 3000 series Al-Mn-Mg alloy family. Compared with 3003 aluminum, it offers higher strength while maintaining excellent corrosion resistance and formability.
The alloy performs well in bending, stamping, roll forming, and welding applications, making it widely used for roofing systems, architectural panels, insulation jacketing, storage tanks, and general industrial fabrication where durability and long service life are important.
The 3004 aluminum sheet is an upgraded rust-proof Al-Mn-Mg alloy plate engineered for applications requiring higher structural strength than standard 3003 aluminum while retaining superior atmospheric corrosion resistance and excellent cold-forming workability. The inclusion of magnesium alloy additions provides enhanced yield and tensile strength, making 3004 aluminum sheets ideal for high-strength building cladding and precision deep-drawing fabrications.
Compared to non-heat-treatable 1000 and 3000 series aluminum grades, 3004 aluminum sheet delivers outstanding resistance to environmental oxidation, excellent weldability via standard TIG/MIG techniques, and superior deep-drawing capability without edge cracking. It performs exceptionally well in severe press bending, stamping, and roll-forming operations, making it a preferred alloy for exterior roofing panels, siding covers, and heavy industrial processing containers.
For international sheet fabricators, roofing contractors, and wholesale metal stockists, our manufacturing facility ensures precise sheet thickness tolerances, uniform surface quality, and competitive factory-direct pricing for continuous batch orders. All raw metal sheet plates strictly comply with recognized global quality standards such as ASTM B209 specifications.
These high-strength anti-rust metal sheet plates are extensively specified across architectural construction, food processing, lighting hardware, and industrial containment sectors. Typical applications include:
We supply 3004 aluminum sheet products in a full spectrum of standard sheet dimensions (such as 4×8 ft, 1220×2440 mm, 1500×3000 mm), custom cut-to-length plate sizes, tempers (such as Soft Annealed O, H14, H24, H34), and protective surface options.
Available value-added processing services include precision CNC laser cutting, waterjet shearing, custom press bending, surface embossing, satin brushing, color prepainting, paper interleaving, and heavy-duty PE/PVC laser film application to safeguard plate surfaces during international transit.
Our experienced export logistics team ensures prompt lead times, seaworthy wooden pallet packaging with waterproof protective wrapping, and authentic Mill Test Certificates (MTC) accompanying every shipment for full material traceability.
