Commercial Security Grilles
San Francisco

Securing an area doesn’t always mean it has to be locked up behind a solid door, in cases such as parking garages and storefronts, having a gate that provides visual access is preferred. Security grilles are the perfect solution for when you want to limit access while still allowing people to see what’s on the other side. If you’re in the market for a security grille, or if you need maintenance performed on your current one, give Union Door a call. We specialize in the installation, maintenance, and repair of all types of commercial doors including grilles, gates, roll-up doors, fire-rated doors, and more. Call today and let us know how we can help!

Commercial Security Grille Benefits and Applications

Security grilles provide the visibility you want and the protection you need. Designed to be durable, customizable, and easy to maintain, these versatile doors can be used in a main entryway, or to partition off particular areas. Because they are not made of solid material, they’re also ideal for places that would benefit from light and air circulation.

Because of their construction and attractive appearance, security grilles are often used for parking garages, storefronts, and other customer-facing areas. If you want to block unauthorized access without creating an “out of sight, out of mind” situation, a security grille may be just what you need.
