Manual Roller Shutters

Manually operated roller shutters are a type of roller shutter that is operated by a manual mechanism, as opposed to an electrified one.

There are two main methods of operation for manually operated shutters:

• Spring and lock (push and pull) operation.

This type of operation is ideal for smaller, lighter shutters where weight won’t be an issue. The spring-assisted roller door is balanced by a spring in the barrel, which is tensioned to adjust depending on the door’s weight and height. The door is simply “pushed” and “pulled” to operate. This type of door is not the best option for industrial use, as it can be difficult to operate during winter months. The lock is usually located in the bottom of the T-rail and throws two bolts into the guides rails. Additional bullet locks can be fitted for added security.

• Manual hand chain operation.

This system includes a pulley system and gears that make it easy to operate by simply pulling on a chain that hangs down the side of the shutter. It’s worth noting that the door cannot open or close particularly quickly because the gears slow down the speed. Consequently, hand chain shutters are only suitable for doors that are not used often.

For security, the chain system can be locked by fitting it into a keep at chest height. The chain is usually padlocked and kept inside the building, but in some cases, the door is the last and first point of access, so the chain is kept outside. There are also bullet locks on either side of the door at chest height. These locks are turned with a key and secured in place. For even more security, a hasp and staple mechanism can be welded to the bottom rail or a steel section can be secured to the ground with a heavy duty padlock.

This type of operation is usually restricted to large, steel shutters in the context of warehouses, barns and factories that lack electricity.

Our manually operated roller shutters are available in both steel and aluminium and can be finished in a range of options including powder coating or plastisol coating. All our doors are CE marked and will have the relevant safety components built into them.

Manually operated spring and lock shutters are typically found on smaller openings and made from steel in commerical contexts, or over modest windows and doors and made from aluminium on domestic properties
