HOTSUN operates as a direct factory manufacturer of reliable scaffolding couplers for steel pipe systems. Available in right-angle, swivel, and sleeve coupler types, each fitting features heavy-duty riveted hinged half-clamps secured by through-bolts with hex nuts, with swivel models incorporating toothed mating surfaces to prevent slip under load. Finished in corrosion-resistant yellow zinc or silver galvanised plating. As a direct factory, we support custom tooling based on technical drawings or samples, conduct 100% inspection before shipment, and maintain a typical lead time of about 7 to 25 days, delivering dependable scaffolding hardware for contractors and equipment rental distributors worldwide.
