Advanced Steel Engineering Boosts Durability of Solar Carports

The support system of a solar carport is directly exposed to outdoor conditions and must provide high corrosion resistance and strength. The TF-CP-S-001 system uses Q235B and Q345B steel for its primary support structure, supported by a hot-dip galvanizing process. Q235B is an ordinary carbon structural steel with good plasticity and weldability, while Q345B is a low-alloy high-strength structural steel with stronger load-bearing capacity.

Through hot-dip galvanizing, a dense zinc layer forms on the steel surface. This layer helps resist atmospheric corrosion and extends the service life of the structure, according to the system specifications. The combination of material grades allows the design to balance structural strength and manufacturing practicality.

Environmental loads are a core factor in solar carport selection because they determine structural design requirements. The system is designed with consideration for extreme wind and snow loads, supporting safety across different climate zones.

The stated wind resistance of 216 km/h and snow load resistance of 1.4 kN/m² provide a reference for projects in areas with severe weather exposure. The adjustable tilt range of 5–30° also allows the system to be adapted to project location and annual yield requirements.

Installation flexibility is an important feature of the solar carport system. The TF-CP-S-001 supports both framed and unframed modules and can accommodate a range of photovoltaic panel specifications. During installation, several factors require particular attention.

• Foundation stability: Although the system is designed for high loads, the foundation must be professionally designed according to local geological conditions.
• Material compatibility: The support structure is mainly galvanized steel, but small components may involve aluminum alloy or stainless steel. Installers should consider the risk of electrochemical corrosion from contact between dissimilar metals and apply insulation measures where necessary.
• Tilt setting: The 5–30° tilt range allows optimization according to project latitude to support the best possible annual power generation.

The system is primarily designed for portrait module layout. Before installation, the module clamp specifications should be checked against the mounting rail to help ensure even stress distribution on the back of the modules.
