Solar Carport Mounting System

Guojian (Tianjin) Steel Co., Ltd. is a specialized manufacturer of Solar Carport Mounting System. We operate our own large-scale production facility equipped with multiple CNC processing lines, handling the entire manufacturing process in-house—from steel cutting, punching, and bending to hot-dip galvanizing. We provide comprehensive services—ranging from site surveys and design planning to production and delivery—tailored to various parking environments such as commercial plazas, corporate parks, and public institutions. Our carport structures and parking layouts are customized to specific site conditions, maximizing space utilization and increasing installation capacity. We maintain a substantial inventory of profiles to ensure rapid shipment of standard specifications. Every batch undergoes rigorous load testing and galvanizing quality checks before leaving the factory, and we offer long-term warranties and installation guidance to ensure a worry-free purchasing experience for our clients.

Details:

01 Diverse Carport Structural Designs: Guojian Steel’s carport mounting systems offer a wide range of structural options, including square-tube, T-shaped, C-shaped, 7-shaped, back-to-back connected, and arched designs. Square-tube carports feature a simple, cost-effective structure ideal for mass construction in large parking lots; T-shaped carports utilize a single-sided cantilever design, providing an open, unobstructed space; C-shaped and 7-shaped carports offer aesthetic appeal, making them suitable for high-end locations such as commercial complexes and office buildings; back-to-back connected carports share central support columns to maximize land utilization, making them perfect for ultra-large parking facilities. Customers can flexibly choose the design based on site conditions, the number of parking spaces, and architectural style, achieving a perfect balance between functionality and aesthetics.

02 High-Strength Hot-Dip Galvanized Steel Structure: The main framework of the carport is constructed entirely from Q235B high-strength structural steel. Key components—such as columns, main beams, and crossbeams—undergo CNC punching and bending before receiving a comprehensive hot-dip galvanizing treatment. With a galvanizing layer thickness of ≥85μm, the structure offers exceptional corrosion and rust resistance. Structural connections feature a reinforced design secured by Grade 8.8 high-strength bolts, ensuring overall stability and reliability. Designed to withstand harsh outdoor conditions—including intense sunlight, rain, and temperature fluctuations—the structure boasts a lifespan of over 30 years. It requires minimal maintenance, significantly reducing long-term operating costs, making it an ideal structural material for photovoltaic carports.

03 Dual Value in One Carport: The Solar Carport Mounting System perfectly integrates photovoltaic power generation with parking functionality. Photovoltaic modules installed on the roof generate electricity for economic gain while providing shelter from sun and rain for vehicles parked underneath. In the scorching summer heat, the temperature inside the carport is 15–20°C lower than in open-air parking areas; this effectively protects vehicle interiors, slows paint aging, and spares owners the discomfort of entering a sweltering, "steamer-like" vehicle. On rainy days, the structure provides a sheltered space for owners to enter and exit their vehicles without getting wet. Delivering the dual benefits of "green power generation" and "convenient parking," this system is the premier choice for upgrading parking facilities at corporate campuses, commercial plazas, and public institutions.

04 Professional Waterproofing and Drainage System: The carport roof features an inclined design equipped with specialized waterproof drainage channels between the photovoltaic panels. Rainwater flows from the panel gaps into these channels and is then systematically directed to the ground via downpipes. This complete drainage system effectively prevents leakage through the panel gaps. The water drainage channel is made of aluminum alloy, offering corrosion and rust resistance; waterproof sealing strips at the joints ensure leak-free performance over long-term use. For cantilevered structures—such as C-shaped or L-shaped designs—the drainage direction is professionally engineered to prevent rainwater from dripping onto the center of the parking space, thereby ensuring convenience when entering or exiting the vehicle. This comprehensive waterproofing and drainage design keeps the area beneath the carport dry even during heavy rain, protecting the vehicle and ensuring a comfortable experience for the owner.

05 Safe and Reliable in Extreme Weather: The carport framework utilizes a large-span cantilevered structure that is significantly affected by wind and snow loads. Guojian Steel performs professional structural calculations for every carport project based on local basic wind and snow pressures. Parameters such as column spacing, main beam specifications, and diagonal brace layouts are verified through finite element analysis, enabling the structure to withstand severe typhoons (exceeding Beaufort scale 12) and snow loads up to 40 cm thick. Additional diagonal braces and fixing points are installed at windward corners to prevent structural loosening caused by wind-induced vibration; in areas with heavy snowfall, main beam specifications can be upgraded or column spacing reduced to ensure structural integrity. All connectors feature anti-loosening nuts and anti-slip washers, ensuring the structure remains stable, reliable, and free from deformation or loosening—even under extreme weather conditions.

06 Efficient Construction and Short Timelines: All structural components are prefabricated in the factory. Columns, beams, and purlins are standardized modules that require only bolted connections for rapid on-site assembly, eliminating the need for welding or secondary cutting. A single carport unit (accommodating two vehicles) can be installed by two workers in half a day, while a large-scale project for 100 parking spaces can be completed and handed over within one to two weeks—boosting construction efficiency by over 60% compared to traditional welding methods. The modular design also facilitates future relocation or modification; should the parking layout need adjustment or the structure require moving to a different site, it can be easily disassembled and reassembled, allowing for component reuse. Supported by detailed installation manuals and on-site technical guidance, standard construction crews can quickly master the process, significantly shortening construction schedules and reducing labor costs.

07 One-Stop Solar-Storage-Charging Solution: Our Solar Carport Mounting System feature pre-configured interfaces for EV chargers, allowing for the integration of charging units directly onto the support columns or at the ends of parking bays. This creates an integrated "solar power generation + energy storage + charging" solution. DC power generated by the solar panels can be supplied directly to the chargers, while excess energy is stored in batteries or fed into the grid, significantly reducing charging operational costs. Charging cables can be routed internally through the carport's steel structure, ensuring a clean, aesthetic appearance without the need for additional external wiring. We support a range of charger models—including 7kW AC units and 60kW/120kW DC fast chargers—and offer flexible configurations tailored to client needs, helping to create green, smart EV charging parking lots that align with the growing adoption of electric vehicles.

08 Professional Customization & Comprehensive Warranty: We provide end-to-end services, ranging from on-site surveys and solution design to manufacturing and installation guidance. Our technical team conducts on-site assessments of dimensions, geological conditions, and surrounding structures to develop customized carport plans and structural load calculations based on the specific parking layout, thereby maximizing space utilization and installed capacity. Our products come with a 10-year structural quality warranty and a 25-year service life commitment, backed by 24-hour technical support and regular inspection services. All products are supplied with material certificates, galvanization test reports, and factory compliance certificates, ensuring peace of mind during procurement, installation, and operation—making us a trusted partner for solar carport projects.
