Crimsafe Bi-Fold Security Doors:
Open Up Your Home - Minimise the Risk
Wide alfresco openings and stacker-style doors are where most homes are most exposed. Crimsafe Bi-Fold security doors let you fold your space wide open when you want to entertain — and lock it down completely when you don't.
A Crimsafe bi-fold security door is a multi-panel, hinged security screen built to protect large openings — patios, alfresco areas, and stacker doors — without bars, grilles, or a compromise on airflow. Each panel is fitted with the same 0.9mm Tensile Tuff® stainless steel mesh and Screw-Clamp® fixing used across the full Crimsafe range, so a wide-open entertaining area gets the same forced-entry protection as a standard door. Panels fold away to the side when open and lock down as one continuous barrier when closed.
Why Bi-Fold Doors Need Their Own Security Solution
The Problem with 'wide openings'
Bi-Fold doors and alfresco openings are usually the largest unsecured span in a home — and often the first thing left open on a warm evening. Standard flyscreens offer no real resistance to forced entry, and retrofitting bars or grilles across a large opening ruins the exact indoor-outdoor flow the space was designed for.
Crimsafe bi-fold doors solve this without sacrificing the openness that made you want a bi-fold door in the first place.
How It’s Built
- Multi-panel, hinged design — custom configured for your exact opening.
- Fold in or out — panels can concertina from the middle or from the side, depending on your outdoor space and how the panels need to stack away
- Multiple locking points — spreads security across the full width of the opening rather than relying on a single lock
- Same Crimsafe strength — 0.9mm 304-grade Tensile Tuff® mesh, Screw-Clamp® fixed, tamper-resistant screws throughout
- No bars, no grilles — full, unobstructed views across the opening whether the doors are open or closed

FAQS
Yes. They can be installed to complement your existing glazed bi-fold doors, or fitted as a stand-alone security screen solution if you don’t have doors there already.

No. The Tensile Tuff® mesh is designed to maintain airflow and natural light while stopping forced entry — you get the same breeze through a closed bi-fold security door as you would through an open window.
Yes and stronger again. It uses the same 0.9mm 304-grade stainless steel mesh and Screw-Clamp® technology as every other product in the Crimsafe range, with multiple locking points spread across the full width of the opening.

Crimsafe uses 0.9mm 304-grade Tensile Tuff® stainless steel mesh, fixed into the frame with a patented Screw-Clamp® system rather than a glued or wedged rubber seal. When impacted, the load spreads across the whole frame instead of concentrating on one weak point, which is why Crimsafe consistently outperforms standard screens in independent impact testing.
No. The Tensile Tuff® mesh is designed to maintain airflow and visibility while still stopping forced entry — you get the security without turning your home into a cage.
