We are C-TPAT and PIP Certified

We are proud to be part of international trade programs that help enhance border security and combat organized crime and terrorism.

Partners in Protection (PIP) is a Canada Border Services Agency (CBSA) program that enlists the cooperation of private industry to secure the trade chain, one partnership at a time.

Custom-Trade Partnership Against Terrorism (C-TPAT) partners work with CBP (Customs Border Patrol) to protect their supply chains from concealment of terrorist weapons, and global supply chains are more secure today as a result of C-TPAT. In exchange, CBP provides reduced inspections at the port of arrival and expedited processing at the border.

Our San Francisco Commercial Security Gates & Grilles

The EZ Series

The aptly-named EZ Series is easy to install and easy on the budget. These solid aluminum side folding grilles offer their own pocket doors, and the curtain itself is preloaded in the pocket. This means the whole apparatus is delivered to your San Francisco location already 90 percent assembled, so you can save money and time on the security grille installation process.

EZ series doors offer high standard security and a number of important options, including ADA compliance and emergency egress doors. Add the fact that it sits flush with your facility’s wall studs for a sleek appearance, and you’re looking at a sure winner.

The Slim Line Series

The Slim Line series side-folding security doors offer your business a great deal of flexibility. These security grilles are readily adapted to provide L-shaped or curved pockets. What’s more, they can be produced in different options to suit – and even enhance — the design aesthetic of your San Francisco business. 

Featuring sleek vertical lines to maximize air circulation and visual access even when the door is closed, the Slim Line series fits any application. For maximum security for a new or retrofit, these ruggedly constructed grilles are a great selection for any secured area.

Elite Series

With the launch of the Elite Series security grilles, we presented the world’s first side folding door. Still one of our most popular models, the Elite has been fine-tuned and updated to make it stack as much as 40% tighter. This model is ideal when you want to retrofit, replace an old door, or install a security gate in an extra tall or wide entrance.

Achieve a sleeker look or compensate for construction/installation error with the built-in capability to fine tune curtain height. Create the degree of curve you need to suit your San Francisco facility’s entrance and add safety features as required.

No matter what the size of your San Francisco premises, you’ll be able to easily direct the public away from areas which are off limits or currently under renovation, and reposition the barrier as required.
