Square Tube Solar Carport System

The China Square Tube Solar Carport System directly sold by Guojian suppliers uses an integrated prefabricated welding process in the factory. Key nodes are reinforced and formed in advance, making the overall structure far superior to the traditional on-site assembled car shelters, significantly enhancing the outdoor wind resistance, compression resistance, and durability performance.

Detail advantages

1. Closed-section square tube frame structure: The carport utilizes rectangular square tubes for main beams, uprights, and secondary beams. Closed-section tubing offers superior bending and compressive strength, ensuring the overall structure resists swaying and deformation.

2. Integrated manufacturing process: Key structural joints are pre-welded and reinforced at the factory, resulting in high structural integrity and stability superior to modular, on-site assembled frames—making it ideal for long-term outdoor use.

3. Wide-span, unobstructed design: Optimized column spacing reduces the number of uprights, creating spacious parking bays that do not hinder vehicle entry, exit, or parking, while maximizing site utilization.

4. Dual-purpose functionality: The roof can be fully covered with photovoltaic modules, while the space beneath accommodates parking and EV charging stations, enabling secondary revenue generation from the site.

5. High-performance outdoor corrosion resistance: The entire structure undergoes hot-dip galvanizing to prevent oxidation caused by air and rain; it withstands intense sun and frost, making it suitable for diverse outdoor conditions across different regions.

6. High adaptability for project implementation: Supports custom sizing based on site measurements to match various parking layouts and site widths, and meets requirements for formal engineering approval and inspection.

Core Advantages

1. Robust structure with a high safety factor

The solid, closed-section square tubes offer high load-bearing capacity and excellent structural integrity. The frame resists swaying during strong winds and storms and prevents deformation from snow accumulation, offering safety and stability far superior to standard round-tube carports.

2. Neat and uniform aesthetic

Featuring straight lines and a clean, elegant design, the finished structure looks tidy and attractive. It is ideal for corporate facilities, demonstration parks, and government renovation projects, ensuring a professional appearance that facilitates smooth project acceptance.

3. Exceptional Site Utilization

The wide-span design eliminates the need for closely spaced columns and saves space; existing parking layouts remain unchanged while directly upgrading to a photovoltaic power plant.

4. Hassle-Free Installation and Clean Site

Main components are fully prefabricated in the factory, with on-site assembly limited to bolting; there is no hot-work welding or construction waste, ensuring regulatory compliance and a high acceptance pass rate.

5. Maintenance-Free and Long Service Life

The galvanized coating features strong adhesion—resisting peeling and rust—and withstands long-term outdoor exposure without frequent maintenance, significantly reducing long-term O&M costs.

6. Compatible with Integrated PV and EV Charging

The roof supports full photovoltaic coverage and offers high load-bearing capacity to accommodate EV charging stations and lighting equipment, making it a standard solution for zero-carbon parks.

Technical Specifications Summary

Applicable Scenarios 

PV projects for factory sites, residential complexes, parking lots, and EV charging stations; zero-carbon retrofits, demonstration projects, and tender-based projects.

Application Scenarios

Factory employee parking shelters; PV projects for commercial park parking lots; EV charging shelters for residential complexes; government demonstration PV projects; PV power generation for school and hospital parking areas; upgrade and retrofit projects for existing parking lots.

Project Selection Tips

When selecting a shelter model, prioritize the site's intended use and local climate. In snowy northern regions, prioritize thickened square-tube main beams to increase snow load capacity; in rainy southern regions prone to typhoons, optimize column spacing to enhance overall wind resistance and stability.

For EV charging areas, increasing the shelter height is recommended to facilitate equipment maintenance and vehicle access. For demonstration projects, standard square-tube models are preferred to ensure a neat, uniform finished appearance that meets acceptance standards.

Production, Quality Inspection, and Delivery

Raw material thickness and material quality are strictly verified upon arrival to rule out non-standard tubing. Tubing undergoes CNC cutting and precise alignment; critical structural points feature reinforced welding, followed by weld-seam smoothing and overall galvanization for corrosion protection. Finished units are individually checked for flatness to eliminate defects such as bending or deformation. Accessories are fully supplied and sorted for packaging.

FAQ

1. What are the advantages of square-tube shelters over standard mounting structures?

The integrated frame structure offers superior structural integrity, better load-bearing capacity, and enhanced resistance to wind and snow loads. They also provide a uniform, neat appearance, making them better suited for passing formal project acceptance inspections.

2. Can existing parking lots be retrofitted directly?

Yes. Customized solutions can be tailored to existing parking space dimensions and site foundation conditions without requiring extensive civil engineering modifications.

3. Can the design include integrated EV charging stations?

Absolutely. The structure includes designated mounting points for EV chargers and is compatible with integrated PV-plus-storage and EV charging projects.

4. Will it rust or the paint peel off over time?

It utilizes a hot-dip galvanizing process throughout, offering stable corrosion resistance and a service life of over 25 years under normal outdoor conditions.

5. Can you provide the documentation required for construction approval?

We provide a full set of material reports, structural calculations, inspection documents, and certificates of conformity to meet requirements for grid connection, project approval, and final documentation filing.

6. Can you provide different styles, such as dual-slope or single-slope designs?

Our Square Tube Solar Carport System support customization of various styles—including single-slope, dual-slope, and stepped-span configurations—and tailor the optimal solution based on site lighting conditions and parking layout.
