Product Details


The 3105 H18 Aluminum Trim Coil is a high-performance architectural material designed for exterior window and door wrapping. As an Al-Mn-Mg alloy (1.0–1.5% Mn, 0.2–0.6% Mg), it combines superior formability, corrosion resistance, and aesthetic appeal. The coil features a smooth or textured surface finish with durable color coatings (polyester, PVDF, or acrylic), making it ideal for weatherproofing and decorative applications.


Mechanical Properties

Tensile Strength: 215–260 MPa (H18 temper), providing structural stability.

Elongation: 4–8%, balancing flexibility for shaping and resistance to cracking.

Yield Strength: 195–230 MPa, minimizing deformation under load.
