A roller shutter door is a vertical sliding door system made up of horizontal laths that form the curtain, side guides, bottom rail, barrel assembly, and canopy.

Roller shutter doors are commonly used to provide a high level of security for all types of properties. Depending on the specification, they are traditionally made of galvanized steel or extruded aluminum.

When a manufacturer designs a custom roller shutter, they consider the following factors:

  • Level of security
  • Requirements for airflow and visibility
  • Thermal protection
  • The width and height of the opening
  • Aesthetics and finish
  • Use frequency
  • Operation method
  • Budget
  • Headroom requirements
  • Security features

Roller shutter door components

The essential components that make up a roller shutter door are:

Curtain and lath: The single horizontal lath lengths are held together by the interlocking shape of the lath, which can be flat or convexed. End caps are riveted to each end of the slat to secure it all together to form the roller shutter curtain.

Roller assembly: This is a steel or aluminum tube fitted on both sides of the endplate and used to hold the shutter curtain in place. When the curtain is in use, it rolls around the roller assembly.

Lock: A roller shutter door can be locked in various ways, including a side guide bullet lock, ground lock, or central bottom rail lock.

Bude channels: The “U” shaped vertical sections on the door’s sides allow the curtain to slide up and down securely.

Motor: The motor is located at the top of the door and powers all of the shutter’s mechanical components.

Safety brake: In the event of a motor failure where pedestrian or vehicle access is required, the safety brake prevents the door from dropping.

Canopy: This surrounds the roller shutter door components at a high level to improve aesthetics and prevent entrapment.

Roller shutter doors can be installed during the construction of a building or in existing buildings to offer improved security and fire protection.


As high-security doors, roller shutter doors provide maximum protection and security against theft and vandalism. In addition, they can improve your property’s privacy by shutting off your home’s interior or commercial space from the outside world. As a result, it acts as a deterrent – if people can’t see inside, the risk of theft of your property is reduced. Often roller shutter doors are constructed from strong galvanized steel and provide the highest level of security for your property.

Fire protection

Roller shutter doors can also be specified as certified fire protection doors for up to four hours and linked to the building’s emergency fire protection to contain the fire and prevent its spread.

Environmental protection

You can protect and maintain building temperatures by varying the roller shutter models. Thermally insulated lath can reduce the amount of hot air that escapes and cold air that enters the building, saving you money on energy bills. In addition, roller shutter doors can also filter light based on their design.

Noise cancellation

Insulated roller shutter doors can also reduce outside noise, which is especially useful in densely populated urban areas.


Roller shutter doors are built to last, providing excellent long-term durability and unrivaled protection against forced entry. These doors can also withstand elements such as wind and rain.


Bespoke roller shutter doors are available in several colours and sizes to add an appealing aesthetic to your home or commercial space.
