What are Roller Shutter Slats?
Roller shutter slats are the individual horizontal panels that interlock to form the curtain of a roller shutter door. As the shutter opens and closes, these slats roll around the barrel, creating a flexible but strong barrier that secures the opening.
Slats are typically manufactured from galvanised steel or aluminium, with the material chosen depending on the level of security, weight, and application required. Steel slats are commonly used for heavy-duty commercial and industrial shutters, while aluminium slats are often used for lighter domestic or retail shutters.
Roller Shutter Slats Information and Buying Guide
Types of Roller Shutter Slats
Types of Roller Shutter Slats
There are several different types of roller shutter slats available, including:
- Solid slats for maximum security and privacy
- Perforated slats with small holes to allow limited visibility and airflow
- Punched slats with larger slots providing increased vision and ventilation
- Insulated slats designed to improve thermal and acoustic performance
As spare parts, replacement slats allow damaged sections of a shutter curtain to be repaired without replacing the entire door. This makes them a cost effective solution for restoring the appearance, security, and functionality of an existing roller shutter system.
Important Note โ Always Replace Slats Like for Like
When replacing roller shutter slats, it is essential to use the same slat profile and specification as the original shutter.
Changing the slat type or size can affect:
- The overall weight of the shutter curtain
- How the curtain rolls onto the barrel
- The fit within the guide rails
- The security and structural strength of the shutter
Using the wrong slat type can cause the shutter to jam, run unevenly, or place additional strain on the motor or operating mechanism.
Guide to Roller Shutter Slats
Guide to Roller Shutter Slats
Roller shutter slats are the horizontal profiles that interlock together to form the shutter curtain. Over time, slats can become bent, dented, or damaged, often due to impact, attempted forced entry, or normal wear and tear. In many cases, damaged slats can be replaced individually, allowing the shutter to be repaired without replacing the entire curtain.
However, it is important that replacement slats match the original slat specification. Changing the slat profile, thickness, or material can affect how the curtain rolls on the barrel, the weight of the shutter, and how it travels within the guide rails.
How to Measure Roller Shutter Slats
How to Measure Roller Shutter Slats
When ordering replacement slats, two key measurements are required:
1. Cut Length (Slat Width)
The cut length is the width of the slat excluding the end locks.
This measurement represents the actual metal slat length before the end locks are attached.
2. Overall Width
The overall width is the full width of the slat including the end locks fitted on each side.
End locks help keep the curtain aligned within the guide rails and prevent the slats from moving sideways during operation.
Measuring Tips
Measuring Tips
To ensure accurate replacement slats:
- Remove one of the existing slats if possible and measure it directly
- Measure the cut length without the end locks fitted
- Measure the overall width including the end locks
- Identify the slat profile and height
- Check whether the slats are steel or aluminium
Providing clear photos and measurements can help ensure the correct replacement slats are supplied.
When Slats Can Be Replaced
When Slats Can Be Replaced
Replacing slats is usually possible when:
Only a small section of the curtain is damaged
The remaining slats are in good condition
The barrel, guides, and operating system are still functioning correctly
If the curtain has widespread damage or corrosion, replacing the entire curtain may be more practical.
Replacing roller shutter slats is often a cost-effective way to repair a damaged shutter, restoring both the appearance and security of the installation while avoiding the cost of a full shutter replacement.
Frequently Asked Questions - Replacing Roller Shutter Slats
1. Can damaged roller shutter slats be replaced?
1. Can damaged roller shutter slats be replaced?
Yes. Individual roller shutter slats can often be replaced without replacing the entire shutter curtain. If only a section of the curtain is damaged, new slats can be fitted to restore the shutterโs appearance, security, and operation.
2. How do I know if my roller shutter slats need replacing?
2. How do I know if my roller shutter slats need replacing?
Common signs that slats need replacement include:
- Bent or dented slats
- Cracked aluminium profiles
- Rust or corrosion on steel slats
- Curtain jamming or catching in the guides
- Gaps forming between slats
If the shutter is struggling to open or close smoothly, damaged slats may be the cause.
3. Can I replace just one roller shutter slat?
3. Can I replace just one roller shutter slat?
In many cases, yes. If the damage is limited to a small section, a single slat or a few slats can be replaced. However, if the curtain has multiple damaged sections, replacing a larger portion of the curtain may be more practical.
4. Are roller shutter slats universal?
4. Are roller shutter slats universal?
No. Roller shutter slats vary depending on:
- Slat profile
- Material (steel or aluminium)
- Slat height and thickness
- End lock configuration
- Manufacturer specification
Matching the correct slat type is essential to ensure the curtain operates correctly.
5. Can aluminium and steel slats be replaced with the same type?
5. Can aluminium and steel slats be replaced with the same type?
Not usually. Steel and aluminium slats have different profiles, weights, and fixing systems. Replacement slats must match the original curtain design to maintain correct operation and balance.
6. Can I upgrade my shutter slats when replacing them?
6. Can I upgrade my shutter slats when replacing them?
Yes. In some cases, replacement slats can be upgraded to improve performance. Options may include:
- Perforated slats for visibility and airflow
- Punched slats for higher vision areas
- Insulated slats for improved thermal performance
Compatibility with the existing shutter system must be confirmed.
7. How much does it cost to replace roller shutter slats?
7. How much does it cost to replace roller shutter slats?
The cost depends on the type of slat, material, and number of slats required. As a general guide:
- Aluminium replacement slats: ยฃ15 โ ยฃ40 per slat
- Steel replacement slats: ยฃ20 โ ยฃ60 per slat
Labour costs may apply if professional installation is required.
8. Can roller shutter slats be replaced without removing the whole shutter?
8. Can roller shutter slats be replaced without removing the whole shutter?
Yes. In most cases the shutter curtain can be partially dismantled to remove damaged slats and install replacements. This avoids removing the entire shutter system.
9. Do damaged slats affect shutter security?
9. Do damaged slats affect shutter security?
Yes. Bent or damaged slats can weaken the curtain and create gaps that reduce security. Replacing damaged slats helps restore the shutterโs strength and correct operation.
10. Should I repair or replace my roller shutter curtain?
10. Should I repair or replace my roller shutter curtain?
If only a few slats are damaged, replacing those slats is usually the most cost-effective option. If the curtain has widespread damage or corrosion, replacing the entire curtain may be recommended.
