Security Shutters Explained

1. Introduction

For over 20 years, Roché Security has been supplying quality security shutters to companies and households across the UK. Our bespoke roller shutter doors are tailored to meet specific site requirements. Recognising the challenge of finding the right information to choose suitable doors for your premises, we’ve created this comprehensive guide to security shutter doors.


2. Security Shutters Overview

A security shutter is a vertical rolling door system composed of horizontal laths forming the curtain, side guides, bottom rail, barrel assembly, and canopy. These shutters, commonly made from galvanized steel or extruded aluminium, provide high security for various properties. The size of the opening determines the components’ size and thickness.

When specifying a bespoke roller shutter, consider the following:

Security level
Airflow/Vision requirements
Thermal protection
Width and height of the opening
Frequency of use
Method of operation
Headroom requirements
Safety features



3. Security Shutter Components

Lath & Curtain:

Interlocking horizontal laths, either flat or convex, form the curtain, secured with end caps.

Roller Assembly:

A steel or aluminum tube at the ends of the shutter, around which the curtain rolls.


Various locking methods, including side guide bullet lock, ground lock, central bottom rail lock, or for the higher security products, integrated locking systems

Guide Channels:

“U” shaped vertical sections guiding the curtain securely up and down.


Positioned at the top, it powers the shutter’s mechanical components.

Safety Brake:

Prevents the door from dropping in case of motor failure.


Surrounds high-level components to prevent entrapment and enhance aesthetics.


4. Security Shutter Layout Options

Security shutters can be installed using either “Reveal Fix” or “Face Fix” methods.


5. Key Benefits of Security Shutters
