Ultimate Color Coated Aluminium Coil

ASTM-Certified & Industrial-Grade

Product Overview

The color coated aluminium coil is a premium solution for industrial and architectural applications, combining durability, aesthetic versatility, and superior corrosion resistance. Manufactured with precision under ASTM standards, this product is ideal for roofing, cladding, composite panels, and automotive components.

Technical Specifications

Key Properties & Performance

Tensile Strength

The color coated aluminium coil exhibits outstanding tensile strength ranging from 90–240 MPa, depending on the alloy grade. For instance:

• Alloy 1050/1060: 90–140 MPa (Ideal for roofing and decorative applications due to high ductility).
• Alloy 3003/3105: 140–180 MPa (Balanced strength for automotive and construction).
• Alloy 5052: 210–240 MPa (Superior for marine and high-stress environments).

Bending Strength

Engineered for seamless forming, the product achieves T-Bend 2T flexibility without cracking, making it suitable for curved surfaces and complex architectural designs. The PVDF-coated variants maintain structural integrity even under extreme weather conditions.

Identification & Marking

Each coil is labeled with:

1. Alloy Grade (e.g., 3003 H24).
2. Coating Type (PVDF/PE) and Thickness.
3. Batch Number for traceability.
4. Certification Marks (ASTM, ISO).
5. RAL Color Code for consistency.

Weight Calculation Formula

Calculate coil weight using:

$$\text{Weight (kg)}=\text{Thickness (mm)}\times \text{Width (m)}\times \text{Length (m)}\times 2.71(\text{Aluminum Density})$$

Example: A 0.5 mm × 1,200 mm × 1,000 m coil weighs 1,626 kg.

Understanding Stainless Steel Corrosion

While our color coated aluminium coil is rust-resistant, stainless steel corrosion can occur due to:

1. Chloride Exposure: Coastal or industrial environments degrade protective chromium oxide layers.
2. Mechanical Damage: Scratches expose the iron substrate to oxidation.
3. Low Oxygen Environments: Inhibits self-healing of oxide layers in enclosed spaces.
4. High Temperatures: Weakens protective coatings above 300°C.
