Photovoltaic racking refers to the support structure that arranges the photovoltaic modules in a certain direction and angle and fixes the spacing according to the specific geographic location, climate and solar energy resource conditions of the construction of photovoltaic power generation system. Generally speaking, PV mounts can be divided into three categories: fixed, tilt-adjustable and auto-tracking. It mainly consists of columns, main beams, purlins, weldments, couplings, foundations and so on.
Hot-dip galvanized photovoltaic mounts are surfaces treated with hot-dip galvanizing to improve corrosion resistance. Hot-dip galvanizing, also known as hot-dip zinc plating and hot-dip galvanizing, is an effective way to prevent corrosion of metals, and is mainly used in metal structure facilities in various industries. It is an effective method of metal corrosion protection, mainly used for metal structures in various industries. The rusted steel parts are immersed in molten zinc solution at about 500°C, so that a zinc layer adheres to the surface of the steel parts for corrosion protection, which can generally be achieved for more than 15 years. It is worth noting that, according to the national standard of raw materials, the thickness of the zinc layer is determined, and the general thickness of hot-dip galvanized photovoltaic mounts is between 63~86μm. When you buy hot-dip galvanized PV mounts, you must see whether it meets the national standards. It has a long service life, high strength and good stability; the disadvantage is that the cost is relatively high.
