Stamped right-angle couplers, also known as cross couplers, are integrally stamped and formed from Q235 steel plate and paired with high-strength T-bolts. They are specifically designed for fixing two scaffold steel tubes at a 90-degree perpendicular connection, making them the most commonly used fastening accessory in scaffolding and formwork support systems. The product offers good toughness and is not prone to breaking; it is lightweight and easy to handle and install on site. The surface can be electro-galvanized or color-plated for rust protection and corrosion resistance. The jaw curvature is standard and fits tightly against steel tubes, so it will not easily slip or loosen after locking, and it can be quickly assembled and disassembled with a wrench. It is widely used in exterior building scaffolding, formwork support, cantilever scaffolds, and other projects, and can be reused repeatedly.
