Alloy 3003 Prepainted Aluminium Coil for Long-Lasting Residential Outdoor Mailbox Door Frames
Alloy 3003 prepainted aluminium coil is perfect for residential outdoor mailbox door frames. Crafted from 3000-series aluminum (with manganese), it boasts exceptional corrosion resistance—ideal for harsh outdoor conditions. Its prepainted coating (PVDF/PE) delivers superior weather/UV resistance, long-lasting color, and scratch protection. Easy to fabricate and low-maintenance, it ensures mailboxes stay durable, attractive, and functional for years.
Key advantages include:
-
1. Excellent corrosion resistance
2. Strong coating adhesion
3. Good formability for shaping
4. Lightweight for easy installation
5. UV-resistant to prevent fading
6. Abrasion-resistant for frequent use
7. Low maintenance requirement
8. Durable in outdoor environments

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.
