China's leading torque tube for solar tracker manufacturer and supplier
The torque tube is a critical structural component in solar tracking systems. It connects all photovoltaic modules together, enabling them to adjust the tilt and azimuth of the panels to follow the sun's direction. This ensures the panels always maintain optimal orientation, enhancing energy capture and achieving maximum power generation.
Simultaneously, the torque tube provides structural support and stability for the solar system. As it must withstand harsh outdoor conditions, the material's strength and corrosion resistance are particularly critical. Typically manufactured from galvanized steel, stainless steel, or aluminum, these tubes ensure material integrity while resisting various adverse weather impacts, offering extended service life.
Beyond the conventional circular shape, torque tubes are available in diverse configurations including square, pentagonal, octagonal, and D-shaped designs. This versatility enables solar tracking systems to adapt flexibly to different terrains and building structures, optimizing installation outcomes. Furthermore, well-designed shapes can reduce wind resistance, enhancing system stability under high-wind conditions.
In solar systems, torque tubes are primarily categorized into single torque tubes and double torque tubes. Single torque tubes serve as independent supports for a single row of solar panels, making them particularly suitable for small-scale solar installations designed to maximize space efficiency. In contrast, double torque tubes provide additional stability and are typically used in large-scale industrial applications requiring resistance to high wind and snow loads.
Material selection is critical to the performance of torque tubes. For instance, galvanized steel offers high tensile strength but is heavier and susceptible to corrosion in salty or humid environments. Conversely, stainless steel provides excellent corrosion resistance but carries a higher cost. Aluminum, being lighter and corrosion-resistant, is frequently used in smaller solar installations with strict weight constraints. Therefore, selecting the appropriate material and type of torque tube based on specific application requirements significantly enhances the overall performance and reliability of solar systems.
Our torque tubes are manufactured from high-strength materials and offer multiple size options, including circular hollow sections ranging from 114 mm to 219 mm outer diameter, square sections from 91 x 91 mm to 175 x 175 mm, and rectangular hollow sections from 122 x 61 mm to 200 x 100 mm. For custom dimensions, please contact us for tailored solutions.
Finally, torque tubes offer extensive application scenarios, providing robust support for diverse solar tracking systems. They meet specific project requirements across multiple sectors, including solar power plants, agricultural systems, residential projects, and rooftop solar installations.
As a leading manufacturer and supplier of torque tube for solar tracker products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
