You’ll find an incredible variety of commercial security closures available to meet the needs of your space.

We offer side folding doors and overhead rolling doors that can fit any opening from the smallest cabinet up to the most massive retail entrances.

If you need a custom door, you’ll find that it’s surprisingly easy to get exactly what you want. We have a long history of innovation that continues today. This innovation shows not only in custom solutions, but in the attention to detail that makes doors easier to install and easier for end users to operate. It also shows in how our doors can keep spaces secured without sacrificing elegance and brand awareness.

Whether it’s for a retail space, a community facility, an industrial space, or an office, our security closures are built to meet your exact needs.

Explore Our Product Line

Our closures fall into two different categories: the ones that fold away to the side and those that roll up.

SIDE FOLDING SECURITY GRILLES

If you want a door with a curved track or have an L-shaped opening to secure, choose a side folding door.  Side folding closures have the ability to fill irregular openings so there is less need to compromise the architectural intent. Available in heights up to 14′ (more with custom orders).

ROLL UP SECURITY GRILLES

If you want a motorized operator, or have limited space at the sides of the opening for storing the door curtain, choose on overhead rolling closure. Our overhead rolling grilles have a just as much selection of materials, patterns, and finishes and colors as our side folding models.
