Coiling Grille
Overview:
Rolling grilles offer a versatile solution for security and crowd control, combining visibility with a sleek aesthetic compared to solid coiling doors. These grilles can be customized with various features to suit a wide range of applications. Whether used in enclosed retail shopping malls, airports, train stations, behind glass for ‘smash and grab’ protection, cafeterias, office lobbies, loading docks, or schools, rolling grilles provide effective security for diverse environments.
Colors:
- Straight Lattice or Brick Pattern available
- Grille-style doors allow for full ventilation, promoting airflow and maintaining a comfortable environment inside the secured space
- Constructed with strong steel rods, these doors offer a sturdy and reliable protective layer
- Advanced locking systems, such as the Titan Locking System, with thick lock rods. This adds an extra layer of security to prevent breaches and unauthorized access
- Particularly beneficial in retail settings where product displays and storefronts need to remain visible even when security is a priority

Brick pattern doors wider than 5′-0″ require a straight link running full height of door to prevent sagging.

PARTIAL SOLD SLATS
Combine grille section at eye-level with solid slats in the same curtain. Allows for ventilation with added security, while still being able to see into the next space.
PASS DOOR
Hollow metal doors are ideal in applications where space is too limited for the installation of a standard entry door. A pass door conserves energy by allowing building access via a smaller opening versus opening the entire door.
FAST ACTING DOORS
For high traffic openings or where air flow or temperature control is critical, doors can be designed to operate at more than twice the speed of typical doors, or up to 2 ft/sec
HIGH CYCLE SPRINGS
High Cycle performance available up to 100,000 cycles at an additional cost (i.e. parking garages, sally ports).
SLOPING FLOOR
Bottom bar design can be sloped to accommodate floor conditions that are not level. This allows for the opening to be entire secure and touch the floor at all points.
SAFETY EDGE
Addition of a safety edge to the bottom bar prevents damage to an object in the door’s pathway in addition to minimizing damage to the closure itself. If trying to close the door, the door will stop and open again.
