Up and down, up and down—that wears most doors out, but not ours. High-cycle commercial security grilles from Alumatec offer heavy-duty, commercial-grade security for light to medium-traffic industrial locations that require remote access. This model, the AT-9-HC, is an elevated and motor-operated version of the AT-9. We’ve strengthened it for high-cycle operation by incorporating additional sleeves and axel nuts on rods, zinc-plated copper eyelets, deeper guides, and a full-width top slat for optimal connection to the barrel assembly. Reaping the same airflow and visibility benefits of our standard security grille gate, the AT-9-HC high-cycle commercial security grille also provides a significantly longer lifespan: about 100,000 cycles. This makes it ideal for parking structure applications with up to 50 parking spaces or tenants.
