Roller shutters are one of the most effective ways to protect your property—whether it’s a shopfront, warehouse, office, or home. But many customers ask us: what exactly are roller shutters made of, and how do the materials affect performance?
In this guide, we’ll break down the most common roller shutter materials, their advantages, and how to decide which one is best for your security needs.
The Core Materials Used in Roller Shutters
Most common for high-security applications
Made from galvanised or stainless steel slats that interlock to form a strong barrier
Resistant to impact and forced entry attempts
Suitable for industrial units, warehouses, and high-risk commercial sites
Can be powder-coated in different colours for corrosion resistance and aesthetics
If you’re looking for maximum strength, steel is often the go-to option.
2. Lightweight Roller Shutters
Lightweight but still highly durable
Available in both extruded aluminium (heavier-duty) and foam-filled aluminium (lightweight with insulation benefits)
Corrosion-resistant, making them ideal for coastal environments
Sleek appearance—popular for retail shops and residential properties
Often quieter in operation compared to steel shutters
Aluminium offers a balance between strength, insulation, and modern appearance.
3. Transparent Polycarbonate Roller Shutters
Made from strong polycarbonate panels combined with aluminium profiles
Provide security while allowing visibility—perfect for shopfronts where window displays remain visible after hours
Weather-resistant and lightweight
Not as strong as steel but provide a clear deterrent without blocking light or branding
Ideal for businesses that want to maintain visibility without compromising security.
4. Specialist Materials and Finishes
Depending on the application, roller shutters can also be customised with:
Insulated slats – for energy efficiency and sound reduction
Perforated or punched steel/aluminium – allowing airflow and visibility
Fire-rated materials – designed to resist flames and heat for a specified time
Powder-coated finishes – available in hundreds of RAL colours to suit your branding
Which Material Should You Choose?
When deciding what roller shutter is right for your property, think about:
Security requirements – Is your site high-risk or low-risk?
Environment – Coastal areas benefit from aluminium’s corrosion resistance.
Visibility – Do you want people to see through after hours?
Noise and insulation – Insulated aluminium slats help reduce energy costs and sound.
Budget – Steel is robust and cost-effective; aluminium is lighter and often more versatile.

FAQs: What Are Roller Shutters Made Of?
Q: Are steel or aluminium roller shutters better for security?
A: Steel roller shutters generally provide the highest level of security due to their strength and resistance to impact. Aluminium shutters, while slightly lighter, still offer excellent protection and are often preferred for environments where aesthetics, corrosion resistance, or insulation are also important.
Q: Can roller shutters be insulated?
A: Yes. Foam-filled aluminium slats and some specialist steel shutters provide insulation. This helps with temperature control and can also reduce noise levels inside the building.
Q: Do roller shutters rust?
A: Steel shutters are usually galvanised and/or powder-coated to resist rust. Aluminium shutters naturally resist corrosion, making them ideal for coastal areas. With proper care and maintenance, rust is rarely a problem.
Q: Can I customise the colour of roller shutters?
A: Absolutely. Most shutters can be powder-coated in a wide range of RAL colours. This allows you to match your company branding or blend the shutters with the surrounding architecture.
Q: What are the quietest roller shutters available?
A: Foam-filled aluminium shutters are often the quietest option due to their lightweight construction and insulation. Choosing an electric operation system with a quality motor can also reduce noise during daily use.
