Import Astm Aluminum Coil — Buy in Bulk from Supplier in Viet Nam

ASTM aluminum coil from Shandong Jintuo Metal Materials Co., Ltd. is produced through a sequence of melting aluminum ingots with alloying additions, casting, then hot or cold rolling followed by annealing and transverse shearing to specified width. The source indicates thickness range from 0.1 to 10 mm and width from 600 to 1500 mm, with other dimensions available on request. Standard references include ASTM, JIS H4000, EN573, and GB/T3880, with steel grade designation ASTMB209. The material exhibits low density, good thermal conductivity, and formability characteristics that suit fabricated metal applications. Test protocols cover chemical component analysis, mechanical properties, technical properties, exterior size inspection, and X-ray examination.

Aluminum coil for industrial applications typically employs 1xxx, 3xxx, or 5xxx series alloys depending on corrosion resistance and strength requirements. The specific alloy series is not stated in the source; buyers should request this critical specification. Annealing state determines whether the coil is fully soft (O temper), quarter-hard (H12), half-hard (H14), or other temper designation for subsequent forming operations. Cold rolling refines grain structure and improves surface finish compared to hot-rolled product. Transverse shearing to width ensures square edges and consistent strip geometry for automated processing lines. Surface quality ranges from mill finish to stucco embossed or painted, though the source does not specify available surface treatments beyond the base coil form.

Primary applications include power plant and chemical plant pipeline insulation, heat exchangers, evaporators, heating appliances, and cooking utensils. The construction sector uses this material for roofing, curtain walls, and shelters; automotive and oil tank fabrication represent additional demand segments. Processing services offered include welding, drilling, cutting, bending, stamping, and embossing, suggesting the supplier positions itself as a service-oriented materials provider. Buyers across Southeast Asia, Northern Europe, and Southern Africa are mentioned as export destinations. Warehouse storage is at the company's Liaocheng City location, though the origin country is listed as Viet Nam, creating a geographic discrepancy buyers should clarify.

Shandong Jintuo Metal Materials Co., Ltd. is located in Liaocheng City, described as the capital of steel tubes, in Shandong Province, China. The company operates as a large enterprise trading carbon steel, stainless steel, galvanized color coated products, copper, and aluminum. The source describes a flexible business approach and management mechanism, though no specific details explain what this means operationally. The imported supplier tier and harbor trust tier indicate platform classification without implying verification depth. The 0.00 response rate suggests limited platform-mediated communication history.

The company profile does not state year of establishment, revenue, employee count, production capacity, or major client references. The mention of exporting to Southeast Asia, Northern Europe, and Southern Africa indicates international trading activity, but no volumes or contract durations are provided. Buyers should independently verify business registration, financial standing, and whether the Viet Nam origin designation reflects manufacturing location, trading subsidiary, or routing through a Vietnamese facility. The warehouse location in Liaocheng and origin country discrepancy requires direct clarification from the supplier.
