The double-column bracket is mainly composed of two columns perpendicular to the ground, a beam (or connecting rod), a support rod, a diagonal brace, connectors, and fasteners. The two columns are connected by a beam to form a stable frame structure for supporting photovoltaic modules. The columns are usually made of high-strength materials such as steel or aluminum alloy to ensure the load-bearing capacity and stability of the bracket. The double-column bracket has the advantages of stable structure, strong load-bearing capacity, flexible adjustment, and strong corrosion resistance. It has been widely used in large photovoltaic power stations and in complex climatic conditions.
