The Inverted Angles section is inverted to form a unique force-bearing structure, which can optimize the support stability of the component and enhance the torsion and bending resistance. It is adapted to special installation spaces and is convenient for nesting and connection with other components, saving assembly space. The material is mostly high-strength steel with good processing performance and easy welding or bolting. It is widely used in scenes such as auxiliary support of steel structures and frame reinforcement to improve the flexibility and load-bearing efficiency of the overall structure.
