The immense potential of solar power as a renewable energy source is globally acknowledged, leveraging the abundant, clean, and accessible energy from the sun. To maximize sunlight capture throughout the day, solar panels need to be optimally oriented, a task achieved by solar trackers. Furthermore, these devices adjust solar panels or collectors to follow the sun’s path. Significantly, this enhances their efficiency and energy output by 25% to 40% over fixed installations.

What makes a well-designed solar tracker? What material can support the weight and movement of solar panels or collectors while resisting corrosion and rust from exposure to the elements? It’s simple. The answer is galvanized steel.

This blog will explore the role and benefits of galvanized steel for solar tracking and how it can help you achieve your green energy goals. Stay tuned and learn more about galvanized steel for solar tracking and how the leading steel service center, National Material Company, can enhance your sustainable energy projects.

Galvanized steel is an incredibly powerful material that should not be underestimated.

To produce galvanized steel, manufacturers apply a layer of zinc to the steel, which prevents rust and corrosion. In fact, the function of the zinc coating is to act as a sacrificial anode. This means the zinc layer will corrode before the steel layer beneath it. Various industries and applications widely use galvanized steel due to its low cost, long life, and resistance to mechanical damage.

Galvanized steel offers several advantages: 

  • Less expensive than stainless steel and does not require additional surface treatments or coatings.
  • It has a lengthy lifespan of more than 50 years in average environments and more than 20 years in severe water exposure.
  • The galvanization process controls the coating thickness and quality, making it reliable and consistent.
  • As a result of the zinc coating creating a metallurgical bond with the steel, its mechanical properties are improved, rendering it solid and long-lasting.

Some galvanized steel applications are:

  • Construction — People use galvanized steel for roofing, walling, foundations, and structural components such as beams, columns, and frames.
  • Automotive — Manufacturers use galvanized steel to make body panels, chassis, and other parts that must withstand corrosion and maintain strength.
  • Solar — Mounting systems, frames, and supports for solar panels are made with galvanized steel, capable of enduring severe weather and UV exposure.
  • HVAC — Ductwork, pipes, and fittings for heating, ventilation, and air conditioning systems often utilize galvanized steel due to its ability to prevent both condensation and corrosion.
  • Agriculture — Galvanized steel is used for fencing, silos, greenhouses, and animal shelters. This is because it can resist animal damage and chemical exposure.
