For manual systems, the counterbalance spring is the heart of the operation. If your door feels heavy or drops suddenly, it indicates spring tension loss. We safely re-tension barrel assemblies and replace worn chain hoists or jammed hand-wind systems. Our team in Stevenage ensures your manual doors meet lifting force regulations.
Modern electric shutters rely on complex tubular or outboard motors. Common faults include blown capacitors, limit switch failures, or thermal cut-outs.
