从China供应商批发进口6063 Coated Aluminum Sheet — FOB条款

Mirach Metallurgy Co., Limited produces 6063 coated aluminum sheet from its facility in Chongqing, China, targeting architectural and structural applications where corrosion resistance and surface finish are critical. The base alloy contains magnesium and silicon as principal alloying elements, with the coating layer applied through Mirach's proprietary coating process to enhance weathering performance and decorative options. Sheet dimensions, temper designations, and coating thickness specifications are not stated in the source listing and must be confirmed directly with the supplier. The product departs from bare 6063 sheet in that the coating system (likely a fluoropolymer, polyester, or anodised film) provides additional UV stability and colour retention for exposed building envelopes.

6063 in sheet form sits at the softer end of the 6xxx series, with typical tensile strength of 140-220 MPa in T6 temper and yield strength of 110-170 MPa, depending on gauge and processing history. The coating adhesion, flexibility, and chalking resistance depend on pretreatment (typically chromate or chrome-free conversion coating), primer application, and topcoat curing parameters. Mirach notes that its coated sheet exceeds industrial standard comprehensive performance requirements, though no specific standard numbers (GB/T, ASTM, EN) are cited. Typical substrate gauges for curtain wall applications range from 2.0-4.0 mm for structural support and 0.8-1.5 mm for decorative cladding, though buyers must verify Mirach's actual production range.

Primary applications include aluminum door and window frames, curtain wall panels, pipe railings, stair rails, furniture, and electrical substation components where the combination of conductivity and corrosion resistance matters. The forming characteristics allow both hot and cold working, though coated sheet typically requires brake pressing or roll forming before coating application to avoid cracking the film. Secondary buyers include architectural metalwork contractors, facade system integrators, and OEMs producing solar mounting structures or transport interiors. Trade terms, MOQ, sample policy, and lead times are not specified in the available data and require direct inquiry with Mirach's sales team in Chongqing.

Mirach Metallurgy Co., Limited operates from No.6/f14, Building 9, North Bank Sun Town, in Chongqing, a major industrial municipality in southwestern China with established aluminum processing and automotive supply chains. The company name and product positioning suggest specialization in metallurgical processing and surface-treated aluminum products, though no founding date, ownership structure, or plant capacity figures appear in the source material. Its trust tier is listed as harbor, with zero recorded response rate and no average response time data, indicating limited or unmonitored inquiry handling through this channel.

The supplier emphasizes proprietary coating technology and performance exceeding industrial standards, but provides no ISO 9001, ISO 14001, or specific quality system certifications in the visible profile. No export licence numbers, customs registration codes, or reference projects are listed. Buyers should independently verify Mirach's production equipment (coil coating line, pretreatment capacity, curing oven specifications), quality control laboratory capabilities, and prior export experience to comparable markets. Direct contact with the Chongqing office is essential to obtain technical datasheets, colour charts, warranty terms, and evidence of coating durability testing (QUV exposure, humidity cycling, salt spray).
