HOTSUN operates as a direct factory manufacturer of reliable spring rapid clamps for aluminium formwork and modular concrete construction systems. Engineered with a heavy-duty riveted assembly, each clamp integrates a stamped base plate with four mounting holes, a durable chrome-plated lever handle, a spring-loaded latch, and a pivot locking head, with long steel tie-rod variants available. Designed for fast one-hand clamping and release without power tools, workers can effortlessly tighten formwork panels and walers against casting pressure. Available in corrosion-resistant yellow zinc, silver galvanised, and red painted finishes. 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 fastening hardware for contractors and formwork rental distributors worldwide.
