50mm IR Extruded
50mm IR Extruded Roller Shutter
The 50mm IR (Intruder Resistant) Extruded is LT Doors' heaviest-duty roller shutter, built from a precision extruded aluminium profile for high-security commercial and industrial applications across Wollongong and the Illawarra. It's motorised as standard and suitable for widespan widths up to 7600mm.
Built for Wollongong's coastal conditions
Port Kembla's industrial precinct, mining-related businesses and larger commercial premises across the Illawarra call for a shutter built to a genuinely industrial spec — the 50mm IR's commercial-grade double wall extrusion and choice of single or 3-phase, high-cycle motors are built for exactly that kind of daily, heavy-duty use.
what LT doors thinks
This is the shutter for factories, warehouses, mining sites and large commercial premises where security and duty cycle matter more than budget — it's a step up again from the Heavy Duty 36mm Extruded in both scale and motor options. For a standard shopfront or smaller commercial doorway, the 36mm Extruded will usually do the job for less.
Key features
- Construction: high-quality, strong aluminium alloy, commercial-grade double wall extruded profile
- Finish: high-quality powder-coated finish or natural anodise
- Design: flat face profile on both sides, allows for sign writing
- Motor options: tubular motor or side motor (SIMUBOX), single phase and 3 phase (high-cycle) options
- Safety: safety brakes fitted as standard
- Widespan: suitable up to 7600mm (6100mm anodised)
- Made in Australia
What makes the 50mm IR Extruded different
Most commercial roller shutters top out well under 7600mm and rely on a single motor type. The 50mm IR Extruded's extruded profile and choice of tubular or SIMUBOX side motors, in single or high-cycle 3-phase options, are built specifically for the largest commercial openings and the highest daily cycle counts, with a flat face on both sides that doubles as sign-writing space.
Colours and finishes
Profile finishes include White, Black and Anodised Silver, with matching Guides/Bottom Foot options, plus powder-coated finishes available at extra cost.
Which roller shutter should you choose?
For standard commercial shopfronts and doorways, the Heavy Duty 36mm Extruded is the more cost-effective option. The 50mm IR Extruded is the pick for the widest openings, the highest security requirements, or high-cycle industrial use.
Installation, warranty and upgrades
Measured, supplied and installed by LT Doors' licensed local team, backed by a written workmanship guarantee. Motorised control only, with SIMU controller options (SD100 Hz, S-30 or SD510 depending on motor type) and add-ons including key ring transmitters, radio keypads and wall transmitters. Note: the 50mm IR Extruded isn't supplied with a pelmet — LT Doors can advise on suitable options at quote stage. Photo Safety Cells and a Safety Edge System are recommended for compliance in egress areas and doorways.

I recently had LT Doors in Wollongong install a new garage door, and I couldn't be more pleased with the entire experience. From the start, their communication was excellent—clear, responsive, and professional every step of the way. The price was very competitive for the quality of the door, and they were upfront about all costs, with no hidden fees.
Very happy with the garage door installation. Luke from LLT Doors in Wollongong was prompt with the quote and gave sound advice about the most appropriate door for our property. The price was reasonable. The door was installed on the organised date.
