Alloy 5056 0.65mm Prepainted Aluminium Coil for Marine Ship Ventilation Grilles

Alloy 5056 0.65mm Prepainted Aluminium Coil for Marine Ship Ventilation Grilles

This high-performance aluminium coil, crafted from 5056 marine-grade alloy (known for excellent corrosion resistance and strength in harsh maritime environments) , features a 0.65mm thickness optimized for lightweight durability. Its prepainted surface (e.g., PVDF or PE coating) ensures long-term weather resistance, anti-fading, and aesthetic appeal, making it ideal for ship ventilation grilles . The coil’s mill-finished or embossed texture enhances structural integrity while meeting international standards for marine applications. Widely used in shipbuilding for its anti-acid/alkali properties and compliance with ASTM/DNV certifications , it combines technical precision with cost-effective, eco-friendly performance.

Key advantages include:

Superior saltwater corrosion resistance
(Ideal for harsh marine environments) 

PVDF/PE coatings withstand UV degradation
(Long-term color and gloss retention) 

Lightweight yet high-strength structural performance
(Reduces ship weight without compromising durability) 

Excellent formability for complex grille designs
(Easily bent/cut into custom shapes) 

Low maintenance and non-combustible properties
(Enhances onboard safety and cost efficiency)

Application

 About Prepainted Aluminum Coil

Prepainted aluminum coil, which is produced with aluminum sheet or (aluminum coil) and processed by coating with color. In common sense,

there are two kinds of prepainted aluminum coil-PVDF and PE, which are widely used in aluminum plate, aluminum veneer, aluminum

honeycomb panels,aluminum ceiling, shingles, scrap, pop-top, electronics.

PVDF coatings are known for their durability and weather resistance. They provide a smooth and glossy finish, making them suitable for

architectural applications. PVDF coated aluminum coils are available in a wide range of colors and are often used for exterior cladding,

roofing, and signage.

PE coatings offer good UV resistance and color retention. They are commonly used for interior applications where extreme weather

resistance is not required. PE coated aluminum coils are available in a variety of colors and are used for indoor decorations, ceiling panels, and more.
