Galvanized solar torque tubes play a crucial role in solar field projects, specifically in single-axis tracking panel systems. These torque tubes act as drive shafts, motorized to control the angularity of solar panels and optimize energy capture by following the sun’s movement across the sky. 

Designed as closed sections, these tubes efficiently support the weight of photovoltaic (PV) panels and resist wind loads. Galvanization is a key process for torque tubes as they are exposed to moisture from rain and snow. 

This article will explore the importance of galvanized torque tubes in optimizing energy capture and withstanding environmental factors in solar projects.

Reasons Why Galvanization is Needed in Solar Torque Tubes:

Acting as drive shafts, torque tubes enable the precise control of the angularity of solar panels to maximize energy capture by aligning with the sun’s movement throughout the day.

The design of torque tubes is critical for their performance in solar projects. Typically closed sections, these tubes are often round, square, or rectangular. They are engineered to provide robust support for PV panels while effectively withstanding wind loads and other environmental stresses.

To ensure their longevity and performance, galvanization is vital for torque tubes. The galvanization process involves coating the steel with a layer of zinc, protecting it from corrosion caused by moisture exposure from rain and snow.

By choosing galvanized torque tubes, solar projects can enhance their durability and resist degradation over time due to harsh weather conditions.

Solar Torque Tube Processing and Machining

Advanced manufacturing processes are employed in the production of torque tubes, ensuring high precision and quality. Torque tube machining involves several steps, such as cutting, drilling, shaping, and welding.

Quality assurance plays a crucial role in torque tube manufacturing. Stringent inspections are conducted throughout the production process to ensure that each torque tube meets industry specifications and customer requirements. Non-destructive testing techniques such as ultrasonic testing are often used to detect any potential defects or irregularities.

Machining challenges can arise due to the complex torque tube design. However, innovative solutions have been developed to overcome these challenges. Computer numerical control (CNC) machines enable the precise machining of intricate shapes while maintaining high productivity levels.

The combination of advanced processing techniques and rigorous quality control measures ensures that galvanized torque tubes meet the demanding standards required for their application in solar field projects.

Manufacturing Efficient Galvanized Torque Tubes

The demand for galvanized torque tubes has been on the rise due to their importance in solar energy projects. The Gallatin tube mill, set to commence operations next summer, plans to supply galvanized torque tubes for these projects. 

This mill operates in proximity to the Gallatin sheet mill, which provides the galvanized sheet used for forming the torque tubes. This close collaboration ensures efficient production and quick fulfillment of custom orders for solar energy customers.

Nucor Tubular Products (NTP) expects significant growth in its torque tube business, including products specifically designed for the solar energy market. NTP sources coil from Nucor’s sheet mills, which utilize electric arc furnaces (EAFs) to produce steel with significantly lower carbon emissions compared to traditional blast furnace steelmaking methods.

By leveraging EAF technology and renewable energy sources, reputable steel companies like Nucor are committed to reducing greenhouse gas emissions and producing net-zero GHG emission steel. This commitment aligns with the sustainability goals of solar projects and demonstrates a dedication to a cleaner future.

Benefits of Hot-Dip Galvanizing

Hot-dip galvanizing (HDG) is a highly effective corrosion protection method that provides numerous benefits to torque tubes used in solar projects.

One of the key advantages of HDG is its sustainable nature. Both steel and zinc used in the galvanization process are 100% recyclable without any loss of properties. This ensures that HDG contributes to a circular economy by minimizing waste and conserving resources.

HDG offers durable and long-lasting corrosion protection through barrier protection and cathodic protection mechanisms. The zinc coating acts as a physical barrier, shielding the underlying steel from environmental factors that cause corrosion. 

In addition, even if there are small scratches or abrasions on the coating, the sacrificial nature of zinc ensures cathodic protection by corroding sacrificially to protect exposed steel surfaces.

Furthermore, HDG forms a protective zinc patina over time, enhancing its resistance to harsh environmental conditions. This results in maintenance-free durability, saving costs associated with regular repairs or touch-ups.

The aesthetic appeal of galvanized steel structures is another advantage of HDG in solar projects. The silver-gray appearance of galvanized steel blends well with various environments, complementing industrial installations without disruption.

Final Words

Galvanized torque tubes play a crucial role in managing solar field projects. By utilizing galvanization, these torque tubes are protected from corrosion caused by moisture exposure, ensuring their long-term performance and durability.

Hot-dip galvanizing provides sustainable, durable, and maintenance-free corrosion protection for these tubes. Its barrier and cathodic protection mechanisms, along with the formation of a zinc patina, enhance the longevity of galvanized torque tubes in solar projects.

Considering the significant benefits of using galvanized torque tubes, businesses involved in solar projects are encouraged to explore this reliable solution. Anyways, it is recommended to visit renowned manufacturing companies to ensure best-in-class products and services.
