77mm Widespan 

77mm Widespan Roller Shutter

The 77mm Widespan is LT Doors' widest roll-formed roller shutter profile, suited to residential and commercial garage doors as well as wide commercial windows, shopfronts and doorways, up to 5900mm wide. It's comprehensively engineered for extra strength across Wollongong and the Illawarra.

Built for Wollongong's coastal conditions

Double garage openings on the larger blocks common across Wollongong's newer estates, plus wide commercial shopfronts through the CBD and Port Kembla, are exactly what the 77mm Widespan is built for — the profile rolls smaller than a traditional steel roller door, so it also suits garages with limited headroom.

what LT doors thinks

Once an opening gets close to garage-door width, this is the profile we look at first — the heavier guides, reinforced bottom bar and fully enclosed pelmet with internal rollers are built for that scale, not adapted from a smaller shutter. Given the width and weight involved, we'd generally recommend motorising it rather than relying on manual operation day to day.

Key features

• Construction: high-quality aluminium alloy, foam-filled profile for strength, security and silent operation
• Profile: smooth and curved face, rolls smaller than traditional steel roller doors
• Finish: high-quality painted finish, double-coated plus lacquer for abrasion resistance
• Strength: comprehensively engineered for extra strength, heavy-duty guides and bottom bar
• Pelmet: fully enclosed with internal rollers and reinforcement side plates
• Widespan: suitable up to 5900mm wide
• Made in Australia

What makes the 77mm Widespan different

Wide roller shutters can be prone to sag or a bulky pelmet at this scale. The 77mm Widespan's fully enclosed pelmet with internal rollers and reinforcement side plates is engineered specifically to manage that width without the shutter rolling up larger than a traditional steel roller door would — genuinely useful where garage headroom is tight.

Colours and finishes

Profile options include Cream, Clear Beige, White, Shale Grey, Black, Monument, Silver and Woodland Grey. Pelmets, side frames, guides and bottom bars come in 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 narrower windows and doorways, the 42mm or 55mm profiles are more cost-effective. The 77mm Widespan is the pick for garage doors and the widest commercial openings. For commercial or industrial-grade high security at similarly wide spans, compare the Heavy Duty 36mm Extruded or 50mm IR Extruded.
