Alloy 3003 0.3mm Prepainted Aluminium Coil for Community Mailbox
Groups
The Alloy 3003 0.3mm Prepainted Aluminium Coil is an ideal material for community mailbox groups, offering lightweight durability (density ~2.73 g/cm³) and excellent corrosion resistance due to its manganese-enriched composition . With a 0.3mm thickness and prepainted PE/PVDF coating, it ensures UV resistance, weatherproof performance, and color customization (available in red, blue, green, etc.) for long-lasting aesthetics
in outdoor environments . This coil is processed with mill finish or textured patterns (e.g., diamond, 3/5 bars) to prevent scratches and oxidation,
maintaining structural integrity under frequent use . Its H24 temper balances formability and strength, suitable for fabrication into
mail compartments, doors, or decorative panels while meeting ISO/ASTM standards for construction materials Suppliers typically provide widths up to 1,600mm and coil IDs of 505mm for seamless integration into mailbox assembly lines .
Key advantages include:
- Superior corrosion resistance
- Lightweight yet durable structure
- Long-lasting color coating (PE/PVDF)
- Easy fabrication and customization
- Wide color options for aesthetics
- Weatherproof for outdoor environments
- Low maintenance requirements
- Smooth surface with anti-scratch finish
- Cost-effective compared to steel
- Recyclable and eco-friendly mate
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.

Product Advantages
1.High flatness: the surface is flat and smooth, without obvious
defects such as unevenness, wavy deformation, indentation or
bulging.
2.Uniformity of colour: The colour is uniform and consistent, with
no obvious colour difference.
3.Strong coating adhesion: good adhesion between the coating and
the aluminium coil substrate makes it difficult for the coating to
flake, peel or lose paint.
4.Good weather resistance: PVDF coatings have a colour stability of
more than 20 years compared to 10-15 years for polyester coatings.
5.Strong corrosion resistance: The natural oxidation layer of
aluminium combined with a protective coating such as PVDF ensures
long term durability in harsh environments.
6.Malleability: complex bending and forming without cracking.
