The Aluminum Alloy Double-Column Waterproof Photovoltaic Carport represents a paradigm shift in carport engineering through its utilization of high-strength aluminum alloys. This system combines exceptional corrosion resistance with significant weight reduction, offering a maintenance-free, durable solution specifically engineered for coastal, industrial, and aesthetic-focused environments where steel structures face accelerated degradation challenges.

Advanced Aluminum Alloy Structural System

• High-Strength Alloy Composition: Primary structural members are fabricated from 6000-series aluminum alloys (6005-T5 or 6063-T5), achieving yield strengths of 240-275 MPa while maintaining excellent formability and weldability. 

• Extruded Profile Optimization: All major components utilize custom-designed extruded aluminum profiles that maximize strength-to-weight ratios. Typical profiles include:

• Double-column supports: 120×120mm square hollow sections with 2-4mm wall thickness

• Main beams: 200×120mm I-beam profiles with integrated cable channels

• Weight Efficiency: The complete aluminum structure weighs 65-70% less than an equivalent carbon steel system, reducing foundation requirements and simplifying installation while maintaining equivalent load-bearing capacity.

Corrosion Protection & Durability

Inherent Corrosion Resistance: Aluminum naturally forms a protective oxide layer that self-repairs when damaged, providing maintenance-free performance in:

• Coastal environments (unlimited distance from shoreline)

• Industrial atmospheres (C5-M classification per ISO 12944)

• Chemical processing facilities

• High-humidity tropical climates
