It is generally made of galvanized aluminum-magnesium steel and other materials, with a common thickness of 2.5mm or 3.0mm, and the overall shape is triangular plate. The hole design is diverse, including circular holes, long waist holes, etc., and some are equipped with 4 special bolt holes. It is mainly used to connect components such as columns with inclined beams and diagonal braces. For example, fix its top corner on the column and its top surface on the inclined beam, and form a fixed inclination angle to adapt to the lighting needs of different regions; when connecting diagonal braces, use two triangular connectors to fix the column and diagonal brace, diagonal brace and inclined beam respectively, and use the stability of the triangle to enhance the overall structural firmness of the bracket. It can also fine-tune the bracket angle through the hole position to improve power generation efficiency.
