Dynamic Closures

Founded in 1975, Dynamic Closures Corporation began as a small company in Ontario with the invention of their side folding security grille for storefront security in shopping malls. During the 1980s, they expanded their product line to include rolling doors and other specialty products. Dynamic Closures expanded into U.S., European, and Australian markets to meet the need for their products on a global scale.

The longevity and durability of Dynamic Closures security closures meant that they could be found increasingly outside of the traditional retail security market in spaces like pharmacies and retail spaces, hospitals, schools and universities, offices, airports, government and public buildings, community centers and churches, stadiums and arenas, museums, and all kinds of public spaces.

Dynamic Closures continues to innovate and offer easy-to-use products like series security grilles and closures which include side-folding, overhead rolling, and other special variations. They are one of Alder’s partner manufacturers for side folding doors with perforated side folding closure, the innovative side folding security door design, and premier roll-up security doors: the Lift Ready® rolling grilles.
