WHY DYNAMIC CLOSURES?

Innovation
is our cornerstone

A security grille or door for a store, office, or kiosk needs to be a fortress – but doesn’t need to look like one. The right design can showcase products to window shoppers, harmonize with site architecture, and even add prestige to your client’s brand.

Founded on innovation, we continue to advance our designs every year for better usability, durability, security, affordability, fast delivery time, ease of installation, and aesthetics.

We invest in new technology and in employee development. Providing an environment of empowerment with accountability allows every employee to share in the Company’s success.

Easy to Design.
Easy to Install.

We make it easy to design security doors to fit your space by providing ready-made and custom CAD files. Our expert customer service team will help you keep your focus where it should be: on your vision. Our closures are designed for easy installation – that means no delays and money saved for your clients.

Our downloads of BIM and CAD files are ideal for architects and designers. We also can create custom security gate solutions on request.
