Import 3003 Aluminum Sheet — Buy in wholesale FOB from Supplier in China

Zhejiang Mingda Aluminum Curtain Wall Manufacturing Co., Ltd. supplies 3003 aluminum sheet in O-H112 temper, specifically positioned for architectural and decorative applications rather than heavy industrial fabrication. The coated surface finish supports color customization including red, white, blue, and additional options, with thickness from 1.5 to 5.0 mm and width up to 1800 mm. This Al-Mn alloy composition, approximately 97-98% aluminum with 1.0-1.5% manganese plus trace iron and silicon, delivers corrosion resistance suited to interior and exterior building environments. The O-H112 temper range indicates fully annealed (O) through strain-hardened and partially annealed (H112) conditions, with exact temper availability requiring direct confirmation.

The coated surface treatment distinguishes this product from mill-finish commodity plate, offering enhanced weathering performance and aesthetic consistency for visible applications. Standard 3003-H112 mechanical properties include tensile strength around 110-145 MPa and yield strength of 70-105 MPa, though coated architectural products may be specified to tighter flatness and coating adhesion criteria than bare plate. The 1.5-5.0 mm thickness range targets cladding, fascia, balcony enclosures, and furniture construction rather than structural plate applications. Width capability to 1800 mm permits efficient nesting for large facade panels, reducing waste in curtain wall fabrication.

Target buyers include architectural metalwork contractors, furniture manufacturers, interior design suppliers, and building material distributors sourcing pre-finished aluminum for projects requiring color consistency and surface durability. Applications span interior and exterior decoration, balcony systems, and furniture components where coated aluminum reduces downstream finishing steps. Trade terms, minimum order quantities, and lead times are not stated in the listing and must be confirmed directly with Zhejiang Mingda. Export packaging uses soft material interleaving with wooden box outer protection, which buyers should verify against their receiving and handling capabilities.

Zhejiang Mingda Aluminum Curtain Wall Manufacturing Co., Ltd. operates from Yuhang Fengdou Industrial Zone in Hangzhou Yuhang, Zhejiang Province, China. The company name and product positioning indicate specialization in curtain wall and architectural aluminum systems rather than general industrial plate distribution. Like the first listing, it holds harbor trust tier with 0.00% response rate and zero average response hours recorded, indicating limited platform interaction data. The Hangzhou Yuhang location places it within the Yangtze River Delta manufacturing belt with strong logistics connectivity to Ningbo and Shanghai ports.

The supplier markets under the brand name 'Minida' and emphasizes coated architectural sheet rather than commodity mill-finish products. No information is provided about production capacity, number of coating lines, quality certifications (such as ISO 9001 or ISO 14001), years in operation, export experience, or client project references. The coated product focus suggests investment in coil coating or sheet finishing equipment, but buyers should verify actual coating capability, color matching systems, and whether the company operates coating lines in-house or sources pre-coated substrate. Direct due diligence including factory audit is advisable given the limited disclosed verification data.
