Why Choose Our
Heavy-Duty Security Shutters?

Built for Security

Our shutters are custom-made with either extruded aluminum or steel. That means only maximum protection for your inventory, equipment, and staff.

Weather-Tested & Storm-Ready

Don’t just secure your business against criminals—secure it against the elements. Our rolling shutters are rated for hurricane-force winds, sea spray, and impact damage, making them a reliable line of defense in storm-prone areas.

Employee-Friendly, Yet Criminal-Proof

Security shouldn’t slow you down. Our shutters come with custom access features, allowing you to manage who gets in and out without compromising safety. Even during a power outage, manual override options ensure operations continue smoothly.

Every business is different—so are our shutters. Choose from a range of:

Sizes and color options
Strength levels and finishes
