Explore our core manufacturing capabilities, featuring specialized aluminum rolls, containers, circles, and foil engineered to international standards.
Our operational scale, engineering excellence, and responsive client service set the standard for high-volume raw metal procurement.
The global industrial landscape relies heavily on high-purity, structurally sound aluminum substrates. As a premier China Aluminium Roll Company & Factory, we provide downstream manufacturers with high-performance aluminum coils, circles, sheets, and foils that satisfy rigid metallurgical requirements. The processing efficiency and mechanical reliability of our aluminum rolls are supported by continuous hot-tandem rolling lines, cold rolling processes, and advanced heat treatment ovens designed to regulate alloy tempering precisely.
China's dominance in the non-ferrous metal industry is not merely a matter of sheer capacity, but rather the result of tight integration across the entire manufacturing value chain. Deep vertical integration—from the refining of bauxite and smelting of primary aluminum ingots to advanced precision rolling and surface coating—minimizes transport-related energy loss and raw material overhead. Located within China's primary industrial metal processing hubs, our factory benefits from immediate access to high-grade chemical inputs, localized tooling expertise, and multi-modal transport infrastructure, allowing us to maintain competitive lead times and cost structures.
By leveraging continuous casting and hot rolling technologies, we achieve a high degree of isotropic crystal grain alignment in our aluminum coils. This structural consistency translates directly to superior deep-drawing capability, uniform mechanical elongation, and minimal directional anisotropy during stamp-forming operations. For global procurement teams, sourcing from a consolidated Chinese factory ensures batch-to-batch chemical integrity, reducing scrap rates during high-speed production runs.
Aluminum roll classification requires precise control of trace alloying elements to align material properties with specific application demands. The following table highlights the standard alloys produced at our state-of-the-art facility, indicating their core mechanical qualities and target industrial applications:
| Alloy Series | Key Composition | Primary Mechanical Traits | Typical Industrial Applications |
|---|---|---|---|
| 1xxx Series (e.g., 1050, 1060) | Pure Al (≥99.5%) | Exceptional electrical conductivity, high ductility, superior corrosion resistance. | Lighting reflectors, chemical apparatus, capacitor casings, spinning blanks. |
| 3xxx Series (e.g., 3003) | Al-Mn (1.0-1.5% Mn) | Moderate strength, excellent workability, superb weldability, rust resistance. | Cookware, chemical containers, radiator fins, road signs, HVAC enclosures. |
| 5xxx Series (e.g., 5083, 5754) | Al-Mg (up to 5% Mg) | High mechanical strength, elite marine corrosion resistance, good fatigue properties. | Shipbuilding hulls, pressure vessels, automotive structural components. |
| 8xxx Series (e.g., 8011) | Al-Fe-Si | Ultra-thin tensile strength, high tear resistance, clean surface characteristics. | Food grade packaging containers, pharmaceutical foils, cable wrapping. |
To verify the mechanical integrity of each shipped aluminum roll, our in-house laboratory performs rigorous mechanical tests on samples taken from the beginning and end of each master coil. Tensile testing determines ultimate tensile strength (UTS) and yield strength, while elongation metrics verify formability. Earing tests are critical for deep-drawing alloys (such as 1050/3003) to ensure that downstream cup-forming operations yield clean, symmetrical edges without excessive trim scrap.
Our manufacturing plants maintain certified compliance with ISO 9001, IATF 16949 (Automotive Quality Management), RoHS, REACH, and FDA Food Contact standards. We supply full chemical analysis certificates (MTRs) with every shipment.

Strictly tested 8011 and 1235 alloy foils. Guaranteed sterile and chemically inert, making them suitable for food containers, pharmaceutical packaging, and flexible barrier films.
Highly conductive pure aluminum coils used in power grids, electrolytic capacitors, transformer windings, and custom heat dissipation panels for consumer electronics.
Specialty alloy formulations showing optimal strength-to-weight ratios and high fatigue resistance. Designed to withstand extreme atmospheric pressure changes.
PVDF-coated aluminum sheets and coils engineered for architectural cladding, roofing, insulation systems, and exterior curtain walls. High weatherability and color retention.
Excellent aesthetic and functional rolls for refrigerator liners, oven panels, washing machine basins, and micro-channel air-conditioning tubes.
A primary failure mode in automated stamping lines is inconsistent coil tension or surface contamination on the raw aluminum strip. To resolve this, our processing facility uses multi-roller levelers to regulate residual internal stress. High-precision slitting heads ensure clean, uniform coil edges, preventing localized stress concentrations that can lead to micro-cracks during stamping.
Depending on the downstream forming technique, we supply aluminum rolls with distinct surface profiles. For automotive sheet forming, a light mill finish with controlled roughness (Ra values between 0.8 and 1.6 μm) is applied to retain lubricants during deep drawing. In packaging applications, we supply dry, degreased surfaces or light food-grade oil coatings (DOS) to prevent sticking while protecting the aluminum surface from oxidation. We also offer protective PE films or interlaid paper options to protect mirror-finish surfaces from scratching during handling and fabrication.
Aluminum is naturally highly active and relies on a microscopic, protective passivating oxide film. However, exposure to moisture during transit can cause white rust (aluminum hydroxide) formations. We address this vulnerability through systematic packaging protocols:

How do you prevent water corrosion stains on aluminum rolls during ocean shipping?
We wrap each master coil in multilayer vapor barriers, include heavy-duty silica gel desiccant packs, and secure the rolls on fumigated wooden skids. These packages are hermetically sealed before container loading to protect against ambient moisture and condensation during maritime transit.
