Jinan, China – Jinan Zhongfu Aluminum Material Co., Ltd. has optimized its 1/3 series aluminum coil product line to meet the growing demand for continuous processing materials in global industries. 1/3 series aluminum coils are widely used in coil-to-coil processing, such as roof panel production, packaging material slitting, and automotive interior parts stamping, with the advantages of uniform thickness and stable performance.
Ⅰ Core Advantages of 1/3 Series Aluminum Coils
1/3 series aluminum coils have unique characteristics adapted to continuous processing scenarios:
1 Series (Pure Aluminum Coils): Boast excellent ductility and uniform thickness, suitable for continuous slitting and deep drawing, widely used in food packaging foil, electronic component substrates, and decorative strips.
3 Series (Al-Mn Alloy Coils): Have good anti-rust performance and wear resistance, stable processing performance, not easy to crack during continuous stamping, suitable for architectural roof coils, industrial insulation coils, and automotive interior coils.
Ⅱ Reasons for Choosing Zhongfu Aluminum 1/3 Series Aluminum Coils
1. High-Quality Raw Materials & Strict Quality Control
Our 1/3 series aluminum coils are made of high-purity aluminum ingots and imported manganese ingots (for 3 series), with strict control of chemical composition and casting process to ensure uniform material structure. The thickness tolerance of coils is controlled within ±0.02mm, and the surface is smooth without defects. All products undergo tensile strength testing, corrosion resistance testing (salt spray test ≥1000 hours for 3 series), and coil shape inspection, with a qualified rate of 99.9%. All batches comply with international standards such as ASTM and GB/T.
2. Customized Solutions for Continuous Processing
For food packaging foil production, we provide 1 series aluminum coils with thickness 0.08-0.2mm and narrow width slitting; for architectural roof panel processing, we offer 3 series aluminum coils with thickness 0.3-1.2mm and PVDF pre-coating; for automotive interior stamping, we provide 1/3 series aluminum coils with uniform hardness. Common specifications: thickness 0.05-3.0mm, width 600-2200mm, supporting non-standard customization of coil diameter and slitting width.
3. Professional Technical Support for Coil Processing
Our technical team with more than 10 years of aluminum coil processing experience provides one-stop services for continuous processing scenarios, including coil uncoiling parameter guidance, slitting process optimization, and surface protection scheme customization. We have helped 1000+ customers in packaging, construction, and automotive industries improve processing efficiency.
4. Strong Production Capacity & Reliable Supply Chain
The total annual production capacity of 1/3 series aluminum coils reaches 600,000 tons, with sufficient inventory of common specifications. We adopt professional coil packaging (waterproof film + wooden pallet) to ensure transportation safety, cooperate with major ports to provide flexible international logistics solutions, and provide complete customs clearance documents. The on-time delivery rate is 99.7%.
5. Factory-Direct Pricing & Global Recognition
We eliminate intermediate agents, helping customers save 10-18% of procurement costs. Our products are exported to 50+ countries and regions, serving 320+ distributors and 5,500+ end customers. We hold ISO9001 and SGS certifications, with a customer repurchase rate of 91%.
