As a leading manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we are proud to present our premium 1100 Aluminum Coil 0.3mm x 1000mm Soft Temper O for Flexible Duct. Established in 2025, our company has rapidly grown to become a trusted supplier in the global metal market, with an annual export value exceeding US$50 million and a dedicated team of 51–100 employees. Our ISO9001-certified production processes ensure that every coil delivered meets the highest standards of quality and consistency. This 1100 aluminum coil, specifically designed for flexible duct applications, offers excellent formability, corrosion resistance, and a soft temper that guarantees easy bending and shaping without cracking.
Our 1100 aluminum coil is manufactured from high-purity aluminum (99.0% minimum), providing superior ductility and workability. The O temper (soft) condition makes it ideal for applications where the material must be bent, folded, or formed into complex shapes, such as flexible ductwork for HVAC systems. The precise dimensions of 0.3mm thickness and 1000mm width ensure compatibility with standard duct machinery, reducing waste and improving production efficiency. Below are the detailed technical specifications:
| Parameter | Value |
|---|---|
| Alloy | 1100 |
| Temper | O (Soft) |
| Thickness | 0.3 mm (±0.02 mm tolerance) |
| Width | 1000 mm (±1 mm tolerance) |
| Coil Weight | Customizable (typically 2–3 tons per coil) |
| Surface Finish | Mill Finish (smooth, clean) |
| Tensile Strength | 70–110 MPa |
| Elongation | ≥ 30% |
| Coil ID | 508 mm (standard) |
Key Features and Benefits:
- Exceptional Formability: The O temper ensures the aluminum coil can be easily bent, rolled, and crimped without spring-back or cracking, making it ideal for flexible duct manufacturing.
- Corrosion Resistance: 1100 aluminum offers natural resistance to atmospheric corrosion, extending the life of the ductwork in various environments.
- Lightweight & Durable: With a density of only 2.7 g/cm³, this coil reduces overall system weight while maintaining strength and durability.
- Precise Dimensional Control: Our advanced slitting and rolling technology guarantees tight thickness and width tolerances, ensuring consistent performance and reduced material waste.
- High Thermal Conductivity: 1100 aluminum has excellent heat transfer properties, beneficial for HVAC applications where temperature regulation is important.
- Non-Toxic & Safe: The material is free from harmful coatings, suitable for use in air handling systems.
Our 1100 aluminum coil is widely used in the production of flexible ducts, spiral ducts, and other HVAC components. The soft temper allows for easy spiral winding and flanging, while the 0.3mm thickness provides the perfect balance of flexibility and rigidity. Customers benefit from reduced downtime, faster production cycles, and lower scrap rates. Additionally, we offer customized width and coil dimensions upon request to meet specific machinery requirements.

Frequently Asked Questions (FAQ)
-
What is the main advantage of using 1100 aluminum for flexible duct?
1100 aluminum is highly pure, offering excellent formability and corrosion resistance. The O temper softens the material, making it easy to bend and shape without cracking, which is essential for duct manufacturing. -
Can I get a different thickness or width?
Yes, we offer customizable dimensions. Please contact us with your specific requirements for thickness (e.g., 0.2mm–0.5mm) and width (e.g., 500mm–1500mm). -
What is the typical lead time?
For standard specifications, lead time is 15–20 working days after order confirmation. Custom orders may take slightly longer, depending on the complexity. -
Do you provide samples before bulk order?
Yes, samples are available upon request. We can send a small coil piece for testing. Shipping costs are to be covered by the buyer. -
What packaging do you use for export?
Our standard packaging includes inner waterproof paper, steel strapping, and outer wooden pallet or steel frame, suitable for sea or air freight. Custom packaging is also available. -
Is your aluminum coil suitable for food-grade applications?
1100 aluminum is often used in food contact applications due to its non-toxic nature. However, please verify with your local regulations. We can provide a mill test certificate upon request. -
What is the minimum order quantity (MOQ)?
Our MOQ is typically 5 tons per size. For trial orders, we may accommodate smaller quantities; please inquire. -
Do you have any quality certifications?
Yes, we are ISO9001 certified. Our production process is strictly controlled, and each coil is inspected before shipment.
