Key Features & Technical Specifications
- High Corrosion Resistance: The 3003 alloy with H14 temper provides excellent resistance to atmospheric corrosion, moisture, and chemicals commonly found in HVAC environments.
- Excellent Formability: H14 temper offers a balance of strength and workability, allowing easy bending, stamping, and roll forming without cracking.
- Lightweight & Durable: Aluminum is one-third the weight of steel, reducing structural load while maintaining high strength.
- Consistent Thickness: Precision rolling ensures uniform thickness across the coil, critical for tight-fitting duct joints.
- Customizable Surface Finishes: Available in mill finish, embossed, or with protective coatings (e.g., PVDF, polyester) to meet specific project requirements.
- Wide Range of Dimensions: Thickness from 0.2mm to 3.0mm, width from 100mm to 1600mm, and coil inner diameter options (300mm, 500mm, 508mm).

Advantages for HVAC Applications
Our 3003 H14 aluminum coil is specifically formulated to withstand the harsh conditions inside HVAC systems. The alloy's natural oxide layer prevents pitting and galvanic corrosion, even when exposed to condensation, refrigerants, or cleaning agents. This translates to longer equipment life and reduced maintenance costs for your projects.
The H14 temper provides a good balance of strength and ductility, making it easy to fabricate complex duct shapes without sacrificing structural integrity. Contractors and manufacturers appreciate the consistent quality and tight tolerances, which ensure seamless installation and optimal airflow performance. Additionally, the lightweight nature of aluminum reduces shipping costs and simplifies on-site handling.
We offer customization options including slit-to-width coils, embossed patterns for added rigidity, and protective coatings (such as PVDF) for outdoor applications. Our team works closely with clients to provide tailored solutions that meet specific project specifications.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for 3003 H14 aluminum coils?
A: Lead time is typically 15-25 days after order confirmation, depending on order quantity and customization. We can also arrange expedited shipping for urgent projects. -
Q: Can you provide a mill test certificate?
A: Yes, we provide a mill test certificate (MTC) with each shipment, confirming chemical composition and mechanical properties as per ASTM B209. -
Q: Is this coil suitable for food-grade or pharmaceutical HVAC applications?
A: The 3003 alloy is generally recognized as safe for indirect contact, but we recommend adding a protective coating for enhanced hygiene. Please consult our technical team for specific requirements. -
Q: What surface finishes are available?
A: We offer mill finish, embossed (diamond or stucco pattern), and coated finishes (PVDF, polyester, or epoxy). Coating options are available upon request. -
Q: How do you ensure corrosion resistance in coastal environments?
A: Our 3003 alloy offers natural corrosion resistance, but for coastal areas we recommend a protective coating (e.g., PVDF) to withstand salt spray. We can also supply chromate conversion treatment if needed. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 5 tons per size. For smaller quantities, please contact us to discuss availability. -
Q: Can you supply coils with custom widths and inner diameters?
A: Yes, we can slit coils to your required width (100mm-1600mm) and offer inner diameters of 300mm, 500mm, or 508mm. Custom ID options are available upon request. -
Q: Do you offer samples before bulk order?
A: Yes, we provide free samples (shipping cost paid by buyer) for quality evaluation. Please contact our sales team to arrange.
