As professionals with over a decade of experience in the aluminum sheet export industry, we are frequently asked by overseas clients about the core information of mill finish aluminum sheets. Unlike aluminum sheets that have undergone deep processing such as anodizing and spraying, mill finish aluminum sheets (i.e., rolled raw aluminum sheets) are the raw, unprocessed state of aluminum sheets straight from the rolling mill or extrusion press. They have not undergone any additional surface treatment, retaining the most authentic properties of aluminum. This makes them one of the most basic and commonly used aluminum sheet categories in global industrial and construction fields, and a core product that consistently ranks among our top export orders.
Regarding specifications, we offer a full range of standardized and customized specifications to meet the needs of diverse global clients, adapting to various export scenarios. Thicknesses range from 0.15mm to 300mm, widths can be customized from 100mm to 2650mm, and lengths from 500mm to 16000mm, with tolerances precisely controlled within ±0.01mm, fully complying with international export standards such as ASTM, EN, and GB/T. The alloy grades of mill finished aluminum sheets are mainly from the 1xxx, 3xxx, 5xxx, and 6xxx series, among which 1100, 3003, 5052, and 6061 aluminum are bestsellers, covering common tempers such as O, H14, H32, and H112. They can be flexibly configured according to specific customer applications. Whether it’s a small batch sample order or a large-scale order of tens of thousands of tons, rapid delivery within 7-45 days can be achieved, meeting the timeliness needs of global customers.
The core characteristics of mill finish aluminum sheet perfectly match the overseas customers’ demand for high-performance, cost-effective, and highly adaptable materials.
First, it boasts a significant cost advantage, eliminating the need for subsequent surface treatment processes and making it more competitively priced, thus ideal for bulk purchases.
Second, it exhibits exceptional plasticity, being lightweight yet possessing excellent toughness, easily enabling deep processing such as bending, cutting, welding, and stamping, adapting to the production and processing techniques of various countries.
Third, it possesses inherent corrosion resistance; the naturally formed oxide layer resists daily wear and minor corrosion, with the 5052 series exhibiting marine-grade corrosion resistance, making it suitable for use in coastal areas.
Fourth, it demonstrates outstanding compatibility, serving as a base material for subsequent anodizing, spraying, and polishing, or it can be used directly, balancing practicality and flexibility.
Furthermore, the product surface is scratch-free and stain-free, packaged in export-standard wooden pallets with a blue PE protective film, effectively preventing damage during transportation.
Mill finished aluminum sheet has a wide range of applications, covering multiple core sectors globally, including construction, transportation, industry, and electrical engineering.
In the construction industry, it is commonly used in roof panels, curtain wall linings, and HVAC ducts, making it an essential material for overseas residential, warehouse, and factory construction.
In the transportation sector, it is suitable for trailer panels, truck bodies, and van interiors, with its lightweight properties contributing to improved fuel economy.
In the industrial sector, it is used in storage tanks, machinery housings, and heat exchangers, with its corrosion resistance and ease of processing highly recognized by overseas manufacturing clients.
Furthermore, it is widely used in electrical busbars, temporary signage, and packaging aluminum foil, with exports spanning Europe, America, Southeast Asia, and the Middle East.
Having cultivated a strong export presence for many years, we deeply understand the stringent requirements of overseas clients for product quality and service. Every batch of our mill finish aluminum sheets undergoes rigorous quality inspection, accompanied by complete material certificates and export customs documents, supporting various trade terms such as EXW, FOB, and CIF. From specification selection and sample delivery to order tracking and logistics, we provide dedicated one-on-one service to help clients reduce procurement costs and improve production efficiency. Choosing us means choosing high-quality, cost-effective virgin aluminum sheets, and a worry-free, efficient cross-border procurement experience.
