Choosing a Roller Shutter System by Door Size: Manual, Chain Hoist or Motor
Roller shutters come in three systems, and door size is the main factor in choosing one. In short: manual for doors up to 3.50 m wide and high, chain hoist up to 7 m and electric motor up to 10 m.
Comparison of the three systems
| System | Door size (W x H) | Operation | Typical use |
|---|---|---|---|
| Manual | Up to 3.50 x 3.50 m | Spring system with manpower | Warehouses, factories, commercial buildings, residences |
| Chain hoist | Up to 7 x 7 m | Manpower pulling a chain hoist | Warehouses, buildings, factories |
| Electric motor | Up to 10 x 10 m | Push switch or remote control (signal range about 5-10 m) | Residences, companies, stores, buildings, warehouses, factories, government offices |
Frequently Asked Questions
Which system suits a 5-metre-wide door?
A door wider than 3.50 m is beyond the manual system, so choose a chain hoist system (up to 7 m) or a motor system (up to 10 m).
What is the range of a motorised shutter remote?
About 5-10 metres.
