3105 H18 0.8MM Thickness Smooth/ Textured Color Coated Aluminum Trim Coil for Wrapping Exterior Window and Door

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.

Application Scenarios

• Window/Door Wrapping:
  • Trim covers for window sills, jambs, and door frames.
  • Protection against water infiltration, UV damage, and weathering.
• Exterior Decoration:
  • Fascia boards, soffits, and eave trims.
  • Curtain wall accents and building facades.
• Custom Projects:
  • RV/marine exterior cladding.
  • Commercial signage and retail displays.

Advantages for Window/Door Wrapping

1. Corrosion Resistance: Al-Mn-Mg alloy resists oxidation, salt, and chemical exposure, critical for coastal areas.
2. Design Flexibility:
   • Smooth finishes complement modern architecture.
   • Textured options mimic wood/stone without rot or fading.
3. Low Maintenance:
   • Non-porous surface prevents dirt buildup.
   • Easy to clean with mild detergents.
4. Thermal Stability:
   • Withstands extreme temperatures (-40°C to 80°C), preventing warping.
5. Lightweight: Reduces installation load while maintaining rigidity.
