Alpine’s Industrial-Grille™ rolling security grilles are designed for protection and easy roll-up operation. The superior construction and quality materials used by Alpine guarantee a long life with limited maintenance. Our trouble-free coiling grilles are built to order, with this intention to fit your opening size. Alpine’s overhead coiling grilles have been proven for use on thousands of installations where coiling grilles and high cycle grilles are required for both business and industry.

Overhead coiling grille curtains consists of solid 5/16″ hot-dipped galvanized steel rods covered with PVC sleeves connected with vertical aluminum links. The coiling grille can have either the standard 6″ brick pattern or an optional 6″ or 9″ straight pattern. Rolling security grilles can be either manually or motor operated and utilize structural angle guides. Either a 24 gauge galvanized or paint-primed hood is available. To take up less space inside, the security grilles roll up to store in an overhead coil. Locking choices on the overhead coiling grille includes either a Hasp-pin type for use with padlocks, optional LOC-TITE, or slide bolts.
