Import 3mm Aluminum Sheet — Buy in wholesale FOB from Supplier in China

Henan Huawei Aluminum Industry Co., Ltd. supplies 3mm aluminum sheet in alloy grades 3003 and 5052, with standard dimensions including 1220 x 2440 mm (4 x 8 feet), 1000 x 2000 mm, 1250 x 2500 mm, 1500 x 2000 mm, and 1500 x 3000 mm. The supplier also accommodates non-standard lengths and widths upon request, with typical width options at 1000 mm, 1250 mm, 1500 mm, and 2000 mm. At 3mm thickness, this sheet sits in the medium thickness range for aluminum products, delivering higher strength and rigidity than thinner gauges while preserving the characteristic lightweight nature of aluminum, approximately one-third the weight of equivalent steel sheet. The 3003 grade offers excellent workability and moderate strength with good corrosion resistance, while 5052 provides superior fatigue strength and saltwater corrosion resistance due to its higher magnesium content.

The supplier's 21 years of production and sales experience spans the full alloy series commonly used in sheet form: 1000, 3000, 5000, 6000, and 8000 series. Beyond the featured 3003 and 5052 grades, the company can source 1050, 1060, 1100, 3104, 3105, 5754, and 6061 variants depending on project requirements. Typical mechanical properties for 3003-H14 in 3mm gauge include tensile strength of 145-195 MPa and yield strength of 115-165 MPa, while 5052-H32 achieves 230-280 MPa tensile and 195-240 MPa yield with 12-18 percent elongation. Standard temper designations include H14 (strain hardened, half hard) and H32 (strain hardened and stabilized, quarter hard), affecting bend radius limits and formability. Typical surface finishes include mill finish, with optional brushed, anodized, or pre-painted coatings available from certified mills in the supply chain.

Primary applications for this 3mm aluminum sheet span automotive body panels, signage and display fabrication, marine superstructures, chemical storage tanks, pressure vessels, architectural cladding, and general sheet metal work. The grade 3003 suits cooking utensils, heat exchangers, and food processing equipment where formability matters, while 5052 excels in marine environments, aircraft fuel lines, and heavy-duty vehicle panels. Container-ready bundles facilitate international import and export, though the supplier does not specify exact packaging configurations. Buyers should confirm edge deburring status, protective film application, and interleaf paper requirements to prevent surface scratching during transit. The supplier location in Zhengzhou, Henan Province, positions them near major rail and road networks connecting to Tianjin or Qingdao ports for sea freight.

Henan Huawei Aluminum Industry Co., Ltd. maintains its headquarters at No.52, Dongming Road, Zhengzhou, Henan, China, with postal code 450000. The trust tier registers as harbor, indicating baseline platform verification. The response rate shows 0.00 percent with zero average response hours, suggesting limited engagement through platform messaging. Buyers should initiate contact through direct channels and verify active operations at the Zhengzhou address, as platform responsiveness metrics do not reflect actual production capability or sales team availability.

The supplier claims 21 years of aluminum sheet production and sales experience, though no founding year, annual output figures, workforce size, or revenue data appears in the profile. The material specification references certified mills without naming specific mill partners or smelter sources. The company does not list ISO 9001, ISO 14001, or specific automotive industry certifications such as IATF 16949 in the provided data. Buyers should request factory audit reports, quality management system certificates, and mill test certificate samples before committing to bulk orders. Verify whether Henan Huawei operates its own rolling mill or functions as a trader with mill relationships.
