Which is Better - A Steel or Aluminium Security Shutter?
Whether steel or aluminium is better depends entirely on your specific application. While steel is the traditional choice in the UK, aluminium often provides a stronger, more attractive, and highly secure alternative that many buyers are simply unaware of.
Steel Security Shutters
Steel shutters are the traditional, heavy-duty option most commonly seen on UK commercial premises. They typically feature a single-skin curved profile (around 77mm deep) available in various thicknesses, from a lighter 22-gauge to a heavy 16-gauge. Steel is generally specified when budget is the primary concern and visual appearance is secondary, making it a cost-effective choice for very large windows and industrial doors.
Aluminium Security Shutters
Derived from continental European designs brought to the UK decades ago, aluminium shutters offer a significantly more attractive finish. Unlike single-skin steel, most aluminium profiles are double-skinned and extruded, providing exceptional stability and strength without the industrial look. With a wide variety of subtle designs and colours, they can actively enhance a modern shopfront or domestic property, doubling as excellent light and heat control.
The Danger of Buying on Price Alone
Regardless of the material you choose, focusing purely on the lowest price often leads to a poorly constructed shutter and costly mechanical failures. Hidden cost-cutting measures—such as using underpowered motors, inferior internal barrels, or cheap nylon bearings—will cause a shutter to self-destruct over time. Common specification pitfalls include:
- Sagging Steel: Specifying a steel gauge that is too thin for a wide opening will cause the curtain to sag and place immense strain on the internal components.
- Lightweight Aluminium: Using cheap, lightweight aluminium slats designed only for shading and insulation, rather than extruded slats built for heavy-duty security.
Because there are dozens of slat types at vastly different price points, it is dangerously easy to accidentally buy a weak shutter if price is your only focus. Always remember: buy right, or buy twice!
