Stamped couplers are integrally stamped and formed from Q235 steel plate, including three types: right-angle couplers, swivel couplers, and sleeve couplers. They are compatible with Φ48 scaffold steel pipes and paired with high-strength T-bolts. Right-angle couplers are used for perpendicular fixing of steel pipes, swivel couplers can connect diagonal braces at any angle, and sleeve couplers are used for extending steel pipes. Surfaces can be electro-galvanized or color-plated for rust protection. They feature good toughness and are not easy to break, with tightly fitting jaws, secure anti-slip locking, and can be assembled and disassembled with just a wrench. Widely used in building exterior scaffolding, formwork support, and municipal scaffolding, they can be reused many times.
