As a professional aluminum product manufacturer, Hemaokang Steel (Shandong) Co., Ltd. supplies high-performance aluminum coils in alloys 1100, 3003, and 3105 with a thickness of 1.5 mm. Our coils are produced with a strong focus on material consistency, corrosion resistance, and forming characteristics. We also provide a comprehensive custom slitting service that allows clients to order exact widths, while a 12-month warranty protects every purchase. With our customer-oriented approach and competitive pricing, these coils are an ideal choice for fabricators, distributors, and original equipment manufacturers worldwide.
Understanding the alloy choices
Aluminum coil 1100 contains a minimum of 99% aluminum and is well known for outstanding ductility and excellent corrosion resistance. It is often selected for chemical equipment, reflective insulation, fan blades, and non-critical structural parts. Alloy 3003 is one of the most common aluminum grades because it provides moderate strength and excellent formability. Manganese as a main alloying element improves mechanical properties so that the coil can be used in roofs, siding, heat exchangers, storage tanks, and household cookware. Alloy 3105 offers improved tensile strength compared with 3003, making it suitable for gutters, downspouts, cable covering, and other applications that require a strong yet formable sheet. All three alloys are fully non-heat-treatable and can be easily welded, bonded, or fastened.
The advantage of 1.5 mm thickness
A 1.5 mm coil provides a practical thickness for medium-duty applications. It offers good stiffness and impact resistance while remaining lightweight and workable on conventional press brakes, shears, and roll-forming lines. This gauge is frequently preferred for cladding, machine housing, bus body panels, and ventilation ducting. We control thickness within standard tolerances to ensure smooth feeding and punching in automated production.

All dimensions can be adapted to your precise production requirements. Our technicians can also advise on the best alloy and temper combination for your specific application.
Production and quality control
Every coil is manufactured in a controlled environment with standard process parameters. During production, we monitor thickness, flatness, and surface condition at multiple checkpoints. Tensile testing and bend testing are performed to verify that the material meets the specified mechanical properties. Before packaging, the coil edge condition and inner diameter are inspected to avoid transit damage and installation downtime.
Custom slitting service
We understand that many customers require narrow strips for stamping, roll forming, or edge folding. Our slitting lines can cut master coils into multiple narrow coils with clean, burr-free edges. Custom widths can range from small strips to full-width material. This service reduces cutting waste and saves time for your production process. When placing an order, please mention your exact width requirements, tolerances, and strip quantities.
Key features and benefits
- Excellent corrosion resistance: Aluminum naturally forms an oxide film that protects against moisture, salt, and many chemicals.
- Lightweight construction: Aluminum weighs approximately one-third of steel, which eases handling and lowers shipping costs.
- High formability: The material can be bent, punched, deep-drawn, and roll-formed without cracking.
- Consistent surface quality: A smooth, uniform surface enables better paint adhesion and stable visual appearance.
- Custom width slitting: We deliver exactly the width you need, minimizing waste.
- 12-month warranty: We guarantee reliable quality with a one-year warranty.
Applications
These aluminum coils are used extensively in building and construction, mechanical engineering, transportation, and consumer goods production. Common examples include
- Roofing sheets, flashing, and gutters
- HVAC ducts, fittings, and insulation shells
- Refrigerator liners, freezer trays, and food containers
- Automotive heat shields, license plates, and trim parts
- Electrical enclosures, cabinets, and cable trays
- Signs, display boards, and lighting reflectors
- Heat exchangers, fin stock, and condensers
- Tanks, dryers, and general fabricated parts
Because the alloys are non-toxic and fully recyclable, the material also supports sustainability goals in packaging and equipment design.

Frequently Asked Questions
Q1. What is your minimum order quantity?
Our MOQ for standard aluminum coil is generally one ton per alloy and temper. For custom widths, the MOQ may be adjusted depending on the slitting process. Please contact our sales team with your required dimensions so we can confirm availability.
Q2. Which tempers can you supply?
We supply a wide range of tempers, including O, H14, H16, H18, H24, H32, and H34. The appropriate temper depends on your forming operation and strength requirements. If you are not sure which one to choose, we can provide technical advice based on your application.
Q3. Can you provide custom slitting in narrow widths?
Yes. We operate slitting lines that process master coils into narrow strips. You can specify the width, number of slits, and coil weight. Our edges are clean and free from burrs, ensuring smooth subsequent processing.
Q4. Do you offer samples before mass production?
We do offer samples for validation. Please tell us the alloy, thickness, width, and quantity you need, and we will arrange sample material as soon as possible. Sample cost and freight are negotiable.
Q5. What is your standard export packaging?
Coils are wrapped with anti-corrosion paper, plastic film, and steel strapping, then placed on wooden pallets or crates as necessary. This packaging protects the material from moisture and impact during ocean and overland transportation.
Q6. What is your delivery time?
For stock sizes, dispatch can be arranged within 7-10 days after payment or LC. For production orders, the lead time is typically 15-25 days. We always try to match your required delivery window.
