Hot-dip galvanized steel structures are made with fabricated steel sheets that are coated in zinc to keep them corrosion free. While regular steel is composed of iron which rusts to the point of disintegration on prolonged exposure to moisture, galvanized steel structures ensure structural durability by creating a physical barrier that prevents water from reacting with iron.

This method of galvanization is comparative expensive but reliable than pre-galvanized mounting structures. However, while pre-galvanized structures may be fairly popular among Solar Plant Installers due to their cost advantage, they are not sustainable in the longer run and could rust, corrode and crumble when exposed to rain, humidity, etc in access.
