3. Core Product Advantages

Balanced Mechanical Performance

• The H24 half-hard temper delivers moderate hardness and excellent toughness, avoiding the cracking problem of hard alloy during bending and forming, while possessing enough rigidity to resist daily extrusion and deformation. The 0.4mm precise thickness ensures uniform stress, suitable for precise roll forming and manual bending for window and wall edge trimming.

Superior Outdoor Weather Resistance

• 3105 aluminum alloy contains manganese elements, forming a dense protective oxide layer on the surface. It effectively resists ultraviolet radiation, rain erosion, oxidation and rust in outdoor environments. Coated versions with PVDF finish further enhance color fastness and anti-aging performance, ensuring no fading, peeling or deformation for long-term outdoor service.

Excellent Formability & Processability

• This trim coil features uniform texture, good ductility and flat surface, supporting various deep processing such as bending, stamping, rolling and cutting. It can be freely processed into various irregular shapes to fit window edges, wall corners and special facade structures, meeting diverse architectural decoration design requirements.

Lightweight & High Strength

• Compared with steel trim materials, aluminum coil is lighter in weight, which reduces the overall load of building exterior walls without compromising structural stability. It effectively avoids wall and window frame pressure deformation, suitable for large-area exterior decoration projects.

Aesthetic & Durable Surface

• The product has smooth and flat surface without scratches, bubbles or impurities. Multiple surface treatments and color options are available, with uniform color and strong three-dimensional sense. It perfectly fits modern architectural styles and improves the overall grade of building facades.

Eco-Friendly & Recyclable

• 3105 aluminum material is 100% recyclable, pollution-free and environmentally friendly, conforming to green building and sustainable development standards. It has stable chemical properties and no harmful substance precipitation, safe for long-term building application.

4. Wide Application Range

This AA3105 H24 0.4mm aluminum trim coil is specially tailored for architectural exterior finishing, with highly targeted application scenarios:

• Building Window Surround Decoration: Mainly used for wrapping and trimming residential, commercial and industrial building window frames, covering window edge gaps, protecting window frame structures from wind and rain erosion, and beautifying window facade lines.

• Exterior Wall Edge Trimming: Applied to exterior wall corner wrapping, wall body edge finishing, facade gap sealing and decorative edging, optimizing building exterior details and improving overall flatness and uniformity of the wall.
