In the solar project field, Bar Grating is a steel structural material that are widely used in solar power plants, mainly used in scenes such as walkway, maintenance platform and equipment support. TOPEnergy’s open design allows light to penetrate grating walkway and reduces its wind resistance. It has excellent drainage and ventilation performance, and is making it ideal for maintenance channels and bracket systems for solar panels. Our common materials are carbon steel with galvanized surface treatment, stainless steel and aluminum alloy. The galvanized steel grates have become the first choice for ground power plants due to its low cost and strong weather resistance. The stainless steel and aluminum alloy type walkway are also more suitable for high-corrosion environments or weight-sensitive rooftop solar project sites.
The steel grating walkway meets the requirements of high load and anti-slip safety for solar sites. TOPEnergy has different series of steel grating such as serrated surface or special texture design. Considering most of people’s anti slip worries, those designs specially to prevent operation and maintenance workers from slipping. In addition, its modular design could be quick installed and can be customized in size to suit to different solar panel arrays. For example, heavy duty welded steel grilles can withstand the dynamic load of equipment handling, but the lightweight aluminum grille can reduce the load-bearing pressure on the roof.
According to market data, the stainless steel gratings occupy a dominant position in solar and other industrial applications (about 60% market share), due to the corrosion resistance and high strength characteristics. The steel series grating walkway are especially suitable for photovoltaic power plants in coastal or high humidity environments. In the future, with the increasing demand for lightweight and corrosion-resistant materials in the photovoltaic industry, the market share of aluminum Bar Grating is expected to increase at a compound annual growth rate of 5.5% or higher.
