The double-column bracket, also known as the T-shaped bracket, consists of two columns perpendicular to the ground and a beam. This design significantly enhances structural stability. Currently, the most commonly used mounting structure designs on the market can be categorized into two solutions: single-column bracket and double-column bracket. In this article, we will analyze the characteristics, advantages and applicable scenarios of the two structures, and find the “best.
