Security Grilles
Model Number: ESG10, ESG11 and ESG12


When you need security but don’t want to compromise visibility or air flow, roll down security gates are the perfect solution. All our metal gates are custom manufactured to your specifications and create the safety separation you desire. Safety gates keep valuables, medicines and other desirables safe from unauthorized access while still maintaining a visual appeal.

Multiple sizes, configurations and constructions help protect anywhere from a parts counter security gate to a mall storefront. Overhead rolling gates can be constructed in straight block patterns or brick patterns in various size openings and materials. Commercial security gates require little maintenance as their rugged construction and quality materials assure long security gate life. Storefront gates, counter safety gates or even metal gates used behind plate glass windows all coil above the opening in minimal headroom space for a fuller use of the opening space.

Overhead security gates are the perfect security solutions for schools, government facilities, healthcare, malls, city storefronts and more.

  • Standard construction up to 40′ wide x 20’ high
  • If you need larger size, please contact us

The grilles are constructed for daily use and can withstand operation of up to five cycles per day.  Dependent on curtain configuration and spring selection.

Chain Diverter for MGH Operators
This option moves the auxiliary chain out of the clear opening and to the side of the door – enabling free movement through the door and making a chain bag unnecessary.

Fixed Panels
Grille curtain can be mounted in a fixed frame assembly. It can be installed separately, or installed near a rolling grille curtain to complement the aesthetics. Often used in parking garages.

Hood and Operator Covers
Metal cover to protect the coil or operator from exterior weather, debris or to meet OSHA or UL 325 safety requirements.

Powder Coating Grilles
Powder coat finish in more than 180 colors is available on perimeter components such as the aluminum bottom bar, hoods, wall angles, tubes and fascia. This finish is not available on the grille curtain.

Trim Package
In applications where exterior aesthetics are important, such as hotels, condominiums, convention centers and parking garages, the addition of a trim package can cover unsightly hardware and contribute to the building’s architecture.

VISIONAIRE Open Curtain – Straight
An open curtain design with straight rows and columns.  Available in 9”, 6” or 3” vertical chain spacing. 

VISIONAIRE Open Curtain – Brick
An alternative open curtain design that allows air circulation and full visual access of the area being protected.  Curtain is constructed with offset rows and columns that resemble traditional brick – horizontal 5/16″ diameter solid aluminum rods at 2″ centers. Rods supported by heavy duty aluminum links, held in staggered position by tube spacers throughout the entire curtain assembly.  

VISTAGARD™ Glazed Panel
An option available for increased protection from theft of small articles through the curtain, the VistaGard is constructed of clear 12″ x 3″, 1/8″ thick Lexan® (or equal) panels. The flame retardant poly carbonate panels are secured by bronze color molded nylon links attached to 5/16″ diameter solid aluminum horizontal rods of alloy 5056 H32, creating a barrier against refuse, odors and smoke.

Grille High Cycle Construction
For grilles that will cycle more than 5 times per day, such as parking garages and sally port openings, we recommend Model ESG12 brick pattern configuration. Alternative high cycle options include the Extreme SentryGate® grille and the Extreme 300 Series Grille.

High Cycle Springs
Heavy duty springs manufactured to withstand cycles of 100,000.

Seismic Performance Validation
We can provide project specific seismic calculations for all coiling doors that are mounted Face of Wall to steel or masonry. Seismic performance validation is per ASCE 7-05.

Entrapment Protection
DevicesEntrapment protection devices ensure that a motorized door or grille will not close on an object.  If an object enters path of closure, the entrapment protection device will stop the door or grille from closing and return it to the fully open position.

Guide-Mounted Interlocks
An electrical cutout switch to prevent motor operation if locking device is not first disengaged.

A wide variety of locking options are available to meet your security needs.

Manual Release System
If egress is required on a motorized grille, a wall mounted pull handle disengages the motor to allow the grill to partially open.

Combination Doors
Combine two different slat profiles in the same curtain.  Typically, a standard slat is combined with a perforated slat or even rolling grille for ventilation and security.  

Countertops are available for a complete counter shutter closure solution, and can be UL rated.

There are multiple mullion options –  corner, fixed and removable.

Sloping or Irregular Openings
Our special bottom bar designs can address these conditions.

Superimposed Doors
Combine two different curtains on the same opening. Typically, an insulated door is used in conjunction with an open design rolling grille to provide ventilation. When extreme weather or sound resistance is desired, we can provide superimposed/double insulated curtain assemblies.
