Choosing the right aluminum alloy polycarbonate carport ensures durability and weather resistance for your vehicle. This guide covers key factors like material quality, UV protection, and structural design. With rising demand (global carport market projected to reach $1.2B by 2025), understanding how to compare carport materials becomes essential.

Key Selection Criteria

1. Material Composition

Opt for 6061-T6 aluminum alloy frames (yield strength: 240 MPa) paired with 8-12mm multi-wall polycarbonate sheets. This combination offers 10x better impact resistance than glass while being 50% lighter.

2. UV Protection

Ensure the polycarbonate sheet carport has dual-side UV coating. Premium brands like Palram provide 10-year warranties against yellowing (tested at 1500 kJ/m² UV exposure).

3. Structural Design

• Look for reinforced corner joints
• Minimum 3° slope for water drainage
• Wind resistance rating ≥ 90 mph (tested per ASTM D638)

Installation Process (5 Steps)

Step 1: Prepare foundation with 4" concrete footings (spaced ≤ 8ft apart)

Step 2: Assemble aluminum frame using T-slot connectors (torque to 18 Nm)

Step 3: Install polycarbonate panels with EPDM rubber gaskets

Step 4: Apply silicone sealant on all edges

Step 5: Final inspection for water drainage (test with hose)
