Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your trusted partner in high-quality aluminum solutions. Our 1100 Aluminum Coil 0.3mm is specifically engineered for roofing and cladding applications in building construction, offering a perfect balance of lightweight durability, corrosion resistance, and formability. As a manufacturer with annual export values exceeding US$50 million, we deliver consistent quality backed by ISO9001 certification. This coil ensures long-lasting performance in diverse climates, making it an ideal choice for architects, contractors, and wholesale distributors worldwide.
Key Features and Benefits:
- High Corrosion Resistance: The 1100 alloy (pure aluminum with 99% minimum aluminum content) provides excellent resistance to atmospheric corrosion, ensuring the coil withstands rain, humidity, and UV exposure without degradation.
- Lightweight yet Strong: At only 0.3mm thickness, the coil offers significant weight savings compared to steel or copper, reducing structural load and installation costs while maintaining adequate strength for roofing and cladding.
- Excellent Formability: Perfect for bending, roll-forming, and profiling into various shapes (corrugated, standing seam, flat sheets) without cracking or surface defects.
- Weatherproof and Fire Resistant: Aluminum does not absorb moisture, rot, or support combustion, enhancing building safety and longevity.
- Eco-Friendly and Recyclable: 100% recyclable material helps meet green building standards and reduces environmental footprint.
- Consistent Quality: Produced in our Shandong facility with strict process control, ensuring uniform thickness, flatness, and surface finish across every coil.

Frequently Asked Questions (FAQ)
Q1: What is the minimum order quantity (MOQ) for 1100 aluminum coil 0.3mm?
A: Our standard MOQ is 5 tons per specification. However, we can accommodate smaller trial orders for new customers. Please contact our sales team for details.
Q2: Can the coil be supplied with a protective film?
A: Yes, protective film (PE or PVC) is available as an optional add-on to prevent surface scratches during handling and installation. Please specify your requirement.
Q3: Is this aluminum coil suitable for marine or coastal environments?
A: The 1100 alloy offers good corrosion resistance in most environments, but for severe coastal or industrial areas with high salt/spray, we recommend considering a coated or anodized surface. We can advise on the best option.
Q4: What is the typical lead time for production?
A: For standard sizes and finishes, production takes 15-20 working days after order confirmation. Custom orders may require 25-30 days. We also keep limited stock for urgent requests.
Q5: Do you provide samples before bulk order?
A: Yes, free samples (A4 size or 1kg coil piece) are available for quality evaluation. The customer only pays for shipping. Samples can be sent within 3-5 working days.
Q6: How does the 0.3mm thickness perform in high wind or snow load areas?
A: 0.3mm aluminum coil is suitable for standard roofing and cladding applications. For areas with extreme wind or snow loads, we recommend using a thicker gauge (e.g., 0.5mm) or a stronger temper (H18). Our engineers can provide load calculation support.
Q7: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and other negotiable terms for long-term partners. Payment terms can be discussed based on order value.
Q8: Can you provide a certificate of conformity or mill test certificate?
A: Yes, each shipment includes a mill test certificate (MTC) per ASTM B209 or GB/T 3880, and we can also provide ISO9001 certificate upon request. Third-party inspection is welcomed.
