Heavy Duty 36mm Extruded
Heavy Duty 36mm Extruded Roller Shutter
The Heavy Duty 36mm Extruded is a commercial-grade roller shutter built from a precision extruded (rather than roll-formed) aluminium profile, installed by LT Doors across Wollongong and the Illawarra for high-security commercial and industrial applications. It's the same base profile used to build LT Doors' bushfire-rated FireSafe shutter.
Built for Wollongong's coastal conditions
Commercial strips through Wollongong CBD, Port Kembla and the industrial areas around Unanderra and Kembla Grange call for a shutter built to a higher duty cycle than a standard residential profile — the extruded double-wall construction on the Heavy Duty 36mm is built for that level of daily use, factories, warehouses and shopfronts alike.
what LT doors thinks
We reach for this shutter over the standard roll-formed range whenever a commercial client needs genuine heavy-duty strength — factories, warehouses, pubs, clubs, arcades and shopfronts all get real use out of the extruded profile's extra rigidity. If your property also carries a bushfire risk, ask about the FireSafe, which is CSIRO-tested and BAL-40 rated on this exact same base profile.

What makes the Heavy Duty 36mm Extruded different
Most residential and light commercial shutters use a roll-formed profile, which is cost-effective but lighter duty. The Heavy Duty 36mm Extruded uses a genuinely extruded, commercial-grade double-wall profile instead — the same manufacturing process behind LT Doors' CSIRO-tested FireSafe shutter — built for factories, warehouses and high-traffic commercial doorways rather than just domestic windows.
Colours and finishes
Profile options include Cream, Magnolia Cream, Clear Beige, White, Shale Grey, Black, Monument, Anodised Silver and Woodland Grey. Pelmets, side frames, guides and bottom bars come in Cream, Magnolia Cream, Clear Beige, White, Shale Grey, Brown, Black, Monument and Woodland Grey, with powder-coated options available at extra cost.
Which roller shutter should you choose?
For standard residential windows and doorways, the roll-formed 42mm or Widespan profiles are the more cost-effective option. For commercial or industrial-grade strength, the Heavy Duty 36mm Extruded is the pick — and for bushfire-prone commercial sites, its FireSafe counterpart adds BAL-40 certification on the same profile. For even larger commercial or industrial openings, compare the 50mm IR Extruded.
Installation, warranty and upgrades
Measured, supplied and installed by LT Doors' licensed local team, backed by a written workmanship guarantee. Can be manually operated (steel cable winder, spring loaded with key lock) or motorised, including with the PowerSmart or SolarSmart automation systems.

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.
I called Luke from LT Doors in Wollongong yesterday and he had John out the very next day – such quick and professional service! John was on time, friendly, and got everything sorted with no fuss. Really impressed – highly recommend!
