Product Description

Exterior Aluminum Coil for Window Trim & Architectural Capping

Contractor-Grade Alloy Solutions for Field-Formed Building Envelopes

Exterior window trim (capping) requires a substrate that balances structural rigidity with the high ductility needed for sharp-radius bending. Our aluminum coils are specifically metallurgical-tuned for the siding and

 window industries, providing a weather-tight, maintenance-free cladding solution that protects wood and vinyl sub-frames from moisture infiltration and UV degradation.


## Alloy Performance & Temper Logic

3003-H14/H24 | The "Workhorse" of Window Capping

Designed for residential and light commercial applications, this manganese-alloyed series is the industry standard for field-forming.

  • Brake Compatibility: Optimized for portable brakes, ensuring 90° or 180° bends without "orange-peeling" or surface crazing.

  • Yield Strength: Balanced to maintain its shape against wind-load while remaining easy to manipulate onsite.

5052-H32 | Marine-Grade Structural Trim

For coastal installations (North America) or high-intensity urban environments (Middle East), the 5052 series offers superior magnesium-based corrosion resistance.

  • Salt-Spray Performance: Rated for 3,000+ hours of salt-fog testing.

  • Enhanced Rigidity: Ideal for larger commercial window sills and wider fascia profiles where oil-canning must be minimized.


## Advanced Surface Engineering

Coating Systems for Extreme Environments

  • PVDF (Kynar 500®): The definitive choice for the Middle East and Central Asian markets. Our PVDF coatings provide an ultra-durable finish that resists the chalking and fading associated with extreme UV exposure and desert sand abrasion.

  • High-Performance Polyester (PE): A multi-coat system designed for North American residential projects, offering excellent mar-resistance during installation and a vast palette of architectural color matching.

  • Tension-Leveled Flatness: Every coil undergoes precision tension leveling to ensure absolute flatness, eliminating the "wavy" appearance often seen in inferior trim materials.


## Installation-Ready Features

  • Flexible Paint Chemistry: Our coatings are formulated with high-elasticity resins that expand during the bending process, preventing the micro-fractures that lead to edge-creep and oxidation.

  • UV-Stable Strippable Film: Provided with a 2-mil to 3-mil pressure-sensitive protective film. It acts as a shield during slitting and brake-forming and peels off cleanly without adhesive transfer, even after days of onsite sunlight exposure.

  • Wash Coat Backing: The underside of the coil is treated with a protective primer to prevent galvanic corrosion when the trim comes into indirect contact with dissimilar materials.


## Technical Specifications

  • Thickness Portfolio: * 0.019" (0.48mm): The North American standard for residential window wrap.

    • 0.024" (0.61mm): Heavy-duty commercial grade for increased impact resistance.

  • Slitting Capabilities: Precision slit-to-width (e.g., 14", 20", 24") with a ±0.01mm tolerance.

  • Color Standards: Available in RAL, AAMA-spec colors, and custom matches including matte and low-gloss architectural finishes.


## Compliance & Export Logistics

We provide a comprehensive documentation package for every shipment, ensuring smooth customs clearance and project approval:

  1. ASTM B209 / EN 485 Compliance: Verified chemical and mechanical testing.

  2. AAMA 2605 Certification: For high-performance architectural coatings.

  3. Packaging: Vertical (eye-to-sky) or horizontal (eye-to-wall) packaging on heat-treated ISPM-15 pallets, utilizing multi-layer moisture barriers for sea freight.
