Why choose Corrugated-tube metal grille?
A closure designed around your needs
The waved-tube grille (known as the Cobra grille) closes the access with a very open curtain body that maintains sightlines and airflow. Its construction, guide rails, threshold bar and operating system are adapted after the survey to the passage and frequency of use.
What makes this model different
- High-resistance galvanised steel tubes
- High visibility — shopfront visible 24/7
- Natural ventilation
- Modern aesthetic — wave pattern
- Anti-break-in & anti-glass-smashing barrier
This model is right for you if
Choose the Cobra grille when the shop window, airflow and sightlines must remain widely open behind a physical barrier.
- Shopping centres
- Car parks and ventilated passages
- Shopfronts needing maximum visibility
- Accesses requiring open sightlines
Consider another solution if
Compare a slatted curtain when you need a continuous enclosure, filtered visibility or total blackout.
Security designed for its use
Tubes, links and staples create an open barrier that keeps the access visible and air moving through it. The lock, floor anchoring and reinforced guide rails add restraint; user-safety measures are then defined according to the motorisation and chosen control method.

Frequently asked questions about Corrugated-tube metal grille
What is the difference between the Cobra grille and a slatted curtain?
The Cobra grille is an articulated grille made of open-work steel tubes: it offers high visibility and natural ventilation, keeping your shopfront visible 24/7. A slatted curtain, by contrast, blacks out partially (micro-perforated) or completely (solid slats).
Is the Cobra grille strong against break-ins?
Yes. Its high-resistance galvanised steel tubes reinforced by double staples form a formidable barrier against break-in attempts and glass smashing.
Does installation require major building work?
No. The Cobra grille is installed without heavy masonry work, by our teams in Paris and across Île-de-France.
Can it be motorised and made to measure?
Yes. Manual or motorised operation, made to measure and installed by our teams across Île-de-France. Consult our technicians for the motorisation suited to your needs.
How quickly do you respond in the event of a breakdown?
In the event of a breakdown or a jammed grille, our teams respond within 20 minutes in Paris and across Île-de-France.
Which tube and mesh constructions are available for a Cobra grille?
The compatible construction is specified in the quote after the site survey, according to the access dimensions, required sightlines and site usage.
Which motor suits the dimensions and frequency of use?
The motorisation is selected according to the grille dimensions and operating frequency, then specified in the quote after the site survey.
Which safety and locking options should be specified?
The lock, floor anchoring, reinforced guidance and motorisation-related devices are adapted to the access, then specified in the quote after the site survey.
