Founded in 1975, Dynamic Closures traces its roots to the invention of the side folding security grille.

Manufacturing began in a modest three thousand square foot manufacturing facility in Brossard, Quebec. The company primarily manufactured and supplied side folding products for storefront security in shopping malls. Quickly building upon their early successes, Dynamic Closures expanded into to the US market and moved operations to Cornwall, Ontario in 1978 which provided a closer proximity to the US border.

Fast Growth

In 1981 Dynamic moved to our present day picturesque location just off the banks of the St Lawrence River in the Township of South Stormont, west of Cornwall, Ontario. In the 80’s, Dynamic Closures also expanded their product line to include rolling doors, and other specialty products.

During that time the Company expanded their presence into Europe and established a manufacturing facility in Australia providing the sale and distribution of Dynamic’s unique high-quality products on a more global scale.

Ongoing Innovation

Dynamic Closures continued to grow, by bringing to market industry-leading products, such as the perforated side folding closure, the innovative side folding design of the EZ Grille® and the amazing Lift Ready® rolling grille. Over the years, the effectiveness and flexibility of these products began to see them used increasingly outside of the traditional retail security market, including areas such as schools, airports, government and public buildings, medical facilities, stadiums and arenas, museums, and a multitude of others.

Years of day-in-day-out performance with integrity, tremendous customer care, and innovative designs that are constantly improved upon has positioned the Company as the leader in the aluminum security grille/door industry.

Dynamic Closures has been able to form long term partnerships with several high-profile retail chains and multinational door manufactures. The Company operates through a network of distributors throughout North America and around the globe and is a member of the International Door Association (IDA).
