Customizable Security

Commercial doorways, windows and serving counters vary in width, height and depth — which means one size is not going to fit all. Our grilles are custom-made for a precision fit, providing maximum security. Request a quote for a personalized estimate. We’ll help with finding measurements and choosing the right solution for your space. You can even customize your closure with optional features for increased durability, functionality and visual appeal, such as:

  • Automatic controls: Automate your grille or gate with door controls built for remote operation.
  • Hoods: Protect your door with an attractive hood, designed to conceal and shield your hardware.
  • Durable metals: Galvanized steel links and rods use a protective layer of zinc to guard against premature rust and corrosion.
  • Design options: Security grilles are available in varying patterns made from different materials, which will help you create the right match.
  • Etching: Place your logo directly onto your grille to turn your security door into an attractive billboard.

If you’re not sure which direction you’d like to go, you’ll be happy to know that we offer professional Architectural Design Support. Our designers can help you find a closure that will meet or exceed your requirements. They’ll help you with drawings and specifications, or you can use our drawing generator in the Architect Portal. Upload your sketch to our team and receive drawings in a matter of days, keeping your project moving forward.

When to Replace a Security Grille

Facilities with existing security grilles may need to replace them with new ones to positively impact appearance and function. Older grilles can act up over time, leading to difficulties rolling up or down and a diminished aesthetic appeal. If you’re taking over an existing structure or planning a remodel, remember that it may be time to replace a security grille if it is:


  • Damaged: Whether by accident or by a break-in, if your security grille is damaged, it’s compromising the level of security being provided. It’s also bad for business — it looks sloppy and invites undesirable behavior.
  • Broken: If your grille is slowing down, getting stuck or failing to operate at all, your property is at risk. Replace your security grille to regain your barrier of protection.
  • Outdated: If your grille is very old, using outdated technology or just looking worn out, it’s time to upgrade.
