When people never stop coming and going, you need more than a high-cycle door. Alumatec’s extreme high-cycle security grilles offer the same heavy-duty, commercial grade security as our normal high-cycle doors, but with an even longer lifespan. The AT-9-SHC features the same specifications as our AT-9-HC parking garage security grille, but also provides a significantly increased cycle life—250,000 cycles to the AT-9-HC’s 100,000—for parking structure applications with over 50 parking spaces or tenants. Our extreme high-cycle security grille will be a lasting investment.
