Visionaire Rolling grilles can be used to protect both interior and exterior openings in malls, as well as in commercial and institutional buildings. The open design of the rolling grille allows for full visual access to the areas being protected and also allows for the free circulation of air. The grille is comprised of a series of 5/16" diameter solid aluminum (stainless or
galvanized optional) rods of alloy 5056 H32 at 2" on center (11/2" optional).
Supporting the horizontal rods are vertical chains formed of eyeletted
aluminum (stainless optional) spaced at 9" apart. For added security, the
chains may be specified to be spaced at 6" or 3". At the bottom of the
curtain and housing the various locking mechanisms is the extruded aluminum
tubular aluminum bottom bar. Retaining the curtain at each end are the
extruded aluminum guides that are equipped with polypropylene pile runners.
The guides are supported with either structural steel tubes or wall mounting
angles. Many grille installations utilize structural steel tubes for support
which allows for installation prior to the walls being built. The tubes are
factory prepped for the attachment of all grille components. Tubes are
attached to the slab below and the joists above, thereby becoming
Vistagard: Offers the same features as the VISIONAIRE but adds G.E. Lexan
(or equal) panels to the design. The panel modules are 12" x 3", 1/8" thick,
clear, flame-retardant polycarbonate material that provides for additional
protection from theft of small articles through the curtain and creates a
barrier against refuse, odors, and smoke. The panels are secured by bronzed
molded nylon links.
Finish: Aluminum grilles are available in mill finish, clear or color
anodized. Stainless steel is factory polished and galvanized steel is
Operation: Push-up, hand crank, hand chain (face of wall mounted exposed
guides only) and motor operation. Push up is not recommended for grilles
over 10'-6" in height or widths greater than 16'-4".
EZ Lift: Recently added to the rolling grille line is the EZ Lift package
which extends the maximum width limit for push-up operated aluminum grilles
from 16'-4" to 22'-0". This results in added savings for building owners.
Manual Release System: To meet building exit requirements and ADA compliance
measures, a wall mounted pull handle is supplied which will disengage the
motor drive and allow for the grille to open partially for egress. By
releasing the pull handle, the grille returns to normal motor operation.
