1. Introduction

HAG HAG Ltd. have been providing companies in the UK and across the world with quality roller doors that have been bespoke manufactured to suit specific site requirements for over 30 years. We know it can be difficult to find all the information necessary to choose the right doors for your premises, so we’ve put together this complete guide to roller shutter doors to make the process easier.

2. Roller shutter doors explained

A roller shutter door is a vertical rolling door system comprising of horizontal laths forming the curtain, side guides, bottom rail, barrel assemble and canopy.

Roller shutters are commonly used as a door to provide a high level of security for all types of properties. Depending on the specification it is traditionally manufactured from galvanised steel or extruded aluminium.

They are classified as a machine under EU legislation and must be serviced and maintained by a capable person on a regular basis. The size (height & width) of the opening / roller shutter will dictate the size and thickness of the components used.

When specifying a bespoke roller shutter you will have to consider the following:

• Security level
• Airflow/Vision requirements
• Thermal Protection
• Width & height of opening
• Aesthetics
• Frequency of use
• Method of operation
• Budget
• Head room requirements
• Finish
• Safety features

4. Components


Lath & Curtain

Single lengths of horizontal lath are held together through the interlocking shape of the lath, either a flat or convexed quirk is used. End caps are riveted on each end of the lath to lock them all into place and form the roller shutter curtain.

Roller assembly

This is a steel or aluminium tube fitted at both sides of the end plate, which is used to hold the shutter curtain. The curtain rolls around the roller assembly when in use.


The roller can be locked with numerous methods that can include side guide bullet lock, ground lock, or central bottom rail lock.

Guide Channels

The “U” shaped vertical sections are located at the sides of the door allowing the curtain to slide up and down securely.


A motor is positioned at the top of the door and powers all the mechanical components of the shutter.

Safety Brake

Prevents the door from dropping in the event of motor failure where pedestrian or vehicle access is required.


This surrounds the components of the roller door at high level to prevent entrapment and improve aesthetics.



5. Typical Layouts Diagram


Roller shutters can be installed “Reveal Fix” or “Face Fix” as shown in the diagram below.

7. What are the benefits of installing roller shutters?


Roller shutters can be installed during the property build or installed retrospectively to improve security or fire protection.


As a high security door, roller shutter doors ensure optimum protection and security from theft and vandalism. Shutter doors can strengthen the privacy of your property, shutting out the interior of your home or commercial space to the outside world. This acts as a deterrent: if people cannot see inside, it minimises the risk of theft to your property.

Most commonly manufactured from strong galvanized steel, they offer the highest quality security to your property. Doors can be installed to the interior or exterior of your property depending on the planning constraints.

Fire Protection

Roller shutters can also be specified as a certified fire protection door for up to four hours and be linked to the buildings emergency fire protection, containing the fire and preventing the spread of fire.

Environmental Protection

By varying the roller shutter models, you are able to protect and maintain building temperatures.

The option of thermal insulated lath can minimalise the hot air escaping and cold air penetrating the building saving you unnecessary costs in energy bills.

Shutters can also filter light, covering your whole window or door to prevent light entering.

Noise reduction

Insulated curtain doors can also reduce outside noise, which is especially beneficial in built up city areas. They can also retain noise inside your property, which prevents complaints from neighbours or nearby companies.


Most commonly made from galvanized steel, the doors are built to last, providing excellent long-term durability and unbeatable protection against forced entry. These doors can also provide resistance to elements such as wind and rain. In environments where intermittent buffering occurs, wind resistant shutters can prevent withstanding strong winds.


Available in a wide range of colours and sizes, bespoke doors can provide an attractive aesthetic to your home or commercial space.

With a quick installation process, they can be easily incorporated into the current structure, causing minimal disruption to your home or business. Fitted internally or externally, they are made bespoke depending on the requirements of your building.


With the ability to have punched or perforated sections with-in the curtain, you can use the roller shutter to display products with the benefit knowing they are secure.


Regular maintenance ensures your premises comply with legal obligations and reduce insurance costs. The current Health and Safety Act 1974 Regulation 18 stipulates that all equipment should be:

• suitable for its intended purpose
• safe to use
• in good repair
• subject to a monitor programme of maintenance

All doors should be serviced regularly to correspond with approved construction schemes and must comply with new European regulations. Failure to do so can result in prosecution and can invalidate your insurance and warranty. All documents and plans must be provided during all Health and Safety inspections.

Curtain options & reasons for specification

There are many different styles of curtain across the ranges, the main ones are:

Curved or flat lath
The width of the opening can sometimes dictate if the lath has to be flat or convex. Personal preference to the aesthetics can also be a reason to choose between the two.

Solid Lath
These come in a 50mm lath or 76mm lath and can be flat or convex. Solid lath are used for high security, ensuring no vision through the product and is also the most cost effective model. 50mm lath or 76mm lath can be chosen to either help when there is a head plate restrictions or simply be a personal preference to the aesthetics to the roller shutter.

Punched Lath
Sections of the lath are cut out to allow vision for shops or air flow when used as car park roller shutters..

Perforated Lath
Holes are punched in the lath to allow vision and airflow similar to the punched option but is more cost effective and secure roller shutter system.

Rods securing links & tubes in a variety of patterns allows maximum vision for shops and air flow in car parks and a totally different appearance than the conventional lath shutter.

Most common specification- 76mm Solid

Finish options

• Galvanised Steel products are the most cost effective.

• Aluminium products are mill finished as standard and are the most cost effective.

• Powder coating can be applied to aluminium and steel products to match the door surround.

• Plastisol steel products are an alternative to powder coating but with a slightly more durable finish however it comes in a more restricted range of colour choice.

• Most common specification is powder coating.

Safety devices & controls

Pedestrian door way roller shutters must be installed with a safety brake to ensure that in the event of motor failure the curtain will not close forcefully or endanger personnel. Ensuring safe passage is government legislation.

Safety photo cells and bottom rail safety edges can be specified to stop the roller shutter operating in the event of any obstructions. Key switches and remote controls can be incorporated.


Some electric roller shutters have a built-in self-locking system, others may require locking devices.

Additional guide locks or ground locking devices will improve the security level.

Some ranges of roller shutters doors are attack tested under laboratory conditions so to provide an insurance rating LPS 1175 issue 7 “SR2, SR3 or SR4” when specified.

Fixings of the roller shutter to the substrate must be taken into consideration for security and size of the door.

Head room

The curtain rolls around the barrel at high level, the taller the door the wider the curtain rolls up and more head room is required. Some products are designed for low headroom applications.
