Professional Aluminum Trim Coil for Window Capping & Cladding

Industrial-Grade 1000, 3000, and 5000 Series Solutions

Our aluminum window trim coil is engineered for precision brake-forming and long-term exterior durability. Specifically designed for the building envelope industry, these coils provide a seamless, weather-tight finish for window sills, brick molds, and custom fascia. Whether for the high-UV environments of the Middle East, the strict ASTM standards of North America, or the extreme temperature fluctuations of Central Asia, our material maintains its structural and aesthetic integrity.

Alloy Selection & Mechanical Properties

We provide three distinct alloy tiers to match your specific engineering requirements:

• 3000 Series (3003/3105): The industry standard for residential and commercial window trim. This manganese-stabilized alloy offers superior workability and rust resistance. It is optimized for portable brake-formers, ensuring crisp corners without "orange peeling" at the bend.

• 5000 Series (5052): A high-magnesium, marine-grade alloy for coastal regions or high-wind zones in North America. It provides exceptional tensile strength and maximum resistance to salt-spray corrosion.

• 1000 Series: Highly ductile, 99% pure aluminum suitable for intricate decorative trims and specialized flashing where maximum formability is required.

Advanced Coating Technology for Extreme Climates

The surface of our trim coil is treated with a multi-stage chemical pre-treatment to ensure permanent paint adhesion.

• PVDF (Kynar 500®) Finishes: Essential for Middle Eastern and desert markets. This coating offers the highest level of protection against solar radiation, preventing chalking and color fading even in 50°C+ environments.

• High-Performance Polyester (PE): A cost-effective, durable solution for North American residential projects, offering excellent scratch resistance and a wide range of low-gloss architectural colors.

• Anti-Corrosive Primer: Every coil is backed with a corrosion-resistant wash coat to prevent internal oxidation when in contact with treated lumber or moisture.

Precision Fabrication Features

• Brake-Forming Reliability: Our aluminum is tension-leveled to ensure absolute flatness. The temper (typically H14 or H24) is strictly controlled to allow for sharp 90-degree bends without micro-cracking the coating.

• Protective Film: Coils are supplied with a pressure-sensitive UV-resistant PVC film. This protects the finish during slitting, transport, and onsite bending, and peels off cleanly without leaving adhesive residue.

• Custom Slitting: We offer precision slitting to specific widths (such as 12", 14", or 24") with a width tolerance of ±0.02mm, reducing onsite labor and material waste.

Compliance and Quality Assurance

Our production adheres to international architectural standards, including ASTM B209 (North America) and EN 485. Every batch undergoes rigorous testing:

• T-Bend Test: Ensuring 1T to 2T flexibility without film loss.

• MEK Resistance: Verifying the chemical cure and solvent resistance of the finish.

• Impact Resistance: Testing the coating’s ability to withstand hailstones or onsite mechanical impact.

Logistics for Middle East, North America, and Central Asia

We understand the logistics of heavy industrial materials. Our coils are packaged in sea-worthy, moisture-proof wrapping with reinforced edge protection to prevent transit damage. Whether shipping to Dubai, Almaty, or Houston, we provide full Mill Test Certificates (MTC) and coordinate third-party inspections (SGS/TUV) to ensure the material meets your local building codes.
