1000 3000 Series Aluminum Alloy Coil Used For Roofing Panel

Aluminum alloy coils used as corrugated roofing sheets are a common construction application,

offering advantages such as lightweight properties, corrosion resistance, easy processing, and

aesthetic appeal.

Commonly Used Aluminum Alloy Series

1) 3000 Series Aluminum Alloys (Al-Mn Alloys)

Common Grades: 3003, 3004, 3105

Key Features:

• Excellent corrosion resistance (ideal for outdoor exposure).

• Moderate strength with superior formability, making them easy to roll into corrugated profiles.

• Cost-effective, offering a good balance of performance and price.

2) 5000 Series Aluminum Alloys (Al-Mg Alloys)

Common Grades: 5052, 5083, 5754

Key Features:

• Higher magnesium content (2.5–5%), providing significantly greater strength than 3000 series.

• Outstanding resistance to saltwater and industrial atmospheres, suitable for coastal or high-

humidity areas.

• Good weldability, ideal for large roofing systems requiring seams.

3) 1000 Series Aluminum Alloys (Pure Aluminum)

Common Grades: 1050, 1060, 1100

Key Features:

• High purity (>99% aluminum), offering exceptional corrosion resistance but the lowest strength.

• Excellent ductility, suitable for deep drawing or complex corrugated shapes.

Standard Thickness Selection

Key Benefits

✅ Lightweight: Density 2.7g/cm³ (1/3 of steel), reduces structural load by 30%+

✅ Weather Resistance: PVDF coating (≥25μm) retains color for 25 years

Anodized layer (10-20μm) resists UV degradation

✅ Easy Installation: Standing seam/concealed clip systems (IPX7 waterproof)

Single panels up to 30m long (minimizes seams)

✅ Eco-Friendly: 100% recyclable, 95% lower energy for recycled aluminum

Solar reflectance ≥80% (cuts cooling costs)

Innovative Applications

♦ Solar-Integrated Roofs: 2.0mm 5052 panels with PV (load ≥60kg/m²)

♦ Ventilated Roofs: 0.8mm perforated panels (15-30% open area) + waterproof membrane

♦ Self-Cleaning Nano-Coating: Contact angle >150° (rain-assisted dirt removal)

Company Advantages

We use the Wolrd Advanced Equipments for your Aluminium Alloy Material

• All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland) Company.
they improve the quality of Aluminum alloy slab which can guarantee Aluminium alloy
products with high-performance.

• 1+1+4 hot rolling mills (1 Reversible Roughing Mill +1 Finishing Mill + 4 Tandem Finishing Mills)

We import these equipments from SMS Group (Germany). All the hot finishing rolling mills
adopt the CVC flatness control technology, which can produce hot rolled coils and plates with
ideal flatness.
