Product Description

Product Overview & Key Features

High-performance Prepainted Aluminum Coils & Sheets engineered for severe weather conditions and demanding architectural applications across Chile and South America. Utilizing premium PE (Polyester) and PVDF (Fluorocarbon) coating systems, our color-coated aluminum provides exceptional UV resistance, anti-corrosion protection, and long-lasting color retention for coastal and high-altitude regions.

Superior Weatherability: PVDF coating withstands harsh UV rays, salt spray, and extreme temperature variations.

Flexible Workability: High coating flexibility (T-bend: 0T–2T) ensures no cracking or peeling during roll forming, bending, or stamping.

Custom Surface Finishes: Available in high gloss, matt, metallic, wood grain, stone texture, and custom RAL color matching.

Eco-Friendly & Durable: 100% recyclable aluminum base with zero-VOC/low-emission paint treatment, offering a service life of up to 20–30 years.

Quality Control & Product Details

We implement strict quality inspection at every stage of production—from raw aluminum coil cleaning and chromating to double-bake coating lines and final mechanical testing.

Coating Thickness & Gloss Test: Every batch undergoes T-bend tests, cross-hatch adhesion checks, MEK rub tests, and impact resistance verification to guarantee zero paint stripping during fabrication.

Color Consistency: Computerized color-matching systems ensure precise match with target RAL colors and color uniformity between different production batches.

Seaworthy Export Packaging: Fully wrapped with waterproof plastic film, anti-rust paper, and outer steel/cardboard protection on strong eye-to-sky or eye-to-side wooden pallets.

Company Strength & Production Capacity

Advanced Production Lines: Equipped with multi-color continuous coating lines and high-speed precision slitting equipment.
