Waterproof carbon steel cantilever carport: Innovative drainage, space optimization

This waterproof carbon steel cantilever carport is specially designed to meet the needs of large, medium and small parking lots. Its innovative waterproof system has completely solved the pain point of poor drainage in traditional carports.

Core structure and materials

    • The main frame is made of high-strength carbon steel to ensure a stable and durable structure.

    • Guide rails and waterproof system: Made of aluminum alloy, it combines lightweight, corrosion resistance and aesthetic appeal.

    • The overall design fully meets the customer's comprehensive requirements for safety, ease of installation and aesthetics.

High-efficiency waterproof and drainage

On rainy days, rainwater gathers around the canopy and flows efficiently into the aluminum alloy gutter, then smoothly drains along the gutter to the lower eaves, avoiding the problem of water accumulation.

Unique cantilever design advantages:

    • Elegant and simple: The cantilever bracket design is simple and elegant in shape.

    • Convenient passage: Effectively avoid the obstruction of the vehicle door by the bracket, significantly reducing the risk of vehicle scratches.

    • High space utilization: Supports modular and free combination of multiple parking Spaces, and can be flexibly laid out according to the site to maximize the utilization of space.

    • Universal application scenarios: It can be perfectly adapted to both family private parking Spaces and large public parking lots.

The innovation and engineering value of this design have been verified in global commercial projects. The 1.6MWp BIPV photovoltaic carport project built by Solar First Group at the Q-cell plant in Malaysia in 2019 is a model of large-scale practice of cantilever waterproof carport technology.

This project adopts a reinforced carbon steel main structure and an aluminum alloy drainage system, perfectly adapting to the tropical rainy climate. The inclined roof effectively resists monsoon heavy rain, and the cantilever design ensures unobstructed passage for large logistics vehicles. Moreover, it innovatively integrates double-glass photovoltaic modules to achieve "dual use of one roof" - providing all-weather protection for over 300 parking Spaces in the factory area and generating an average of 1.9 million kilowatt-hours of electricity annually, meeting 15% of the factory's operational electricity demand. 

This benchmark case validates the high reliability, space reuse value and energy conversion potential of the cantilever waterproof carport in complex industrial scenarios.
