Commercial Security
Secure Vestibules
& Walkways
A locked front door is no longer enough
Schools, campuses, and businesses now need a secure secondary barrier that holds visitors in a controlled space until staff verify who they are. Whether you call it a vestibule, a mantrap, or a secure entry, it has become a standard part of modern safety design.
Built for the Way Your Building Works
Security Vestibules
Create a controlled holding area inside your main entrance. Visitors are seen and verified before they ever reach student or staff areas.
Mantraps
Two sets of secured doors with a buffer zone between them. Only one set opens at a time, so no one slips through behind an authorized visitor.
Secure Walkways
Enclose covered walkways between separate buildings, portable classrooms, or wings. Students move between spaces without stepping outside your secure perimeter.
Barriers & Hallway Partitions
Close off corridors, wings, or outdoor areas after hours or during events, with lockable doors where you need access.
Made in the USA · Manufacturing since 1997 · 144,000 psi stainless steel mesh · ADA-compliant egress
Why Steel Mesh?
144,000 PSI tensile strength. Our 304 stainless steel security mesh is woven for strength and built to stand up to forced-entry attempts.
- Nearly impervious to forced entry. High-tensile woven mesh, framed in extruded aluminum and locked in place by a proprietary mesh retention system.
- Open, not closed off. Staff keep clear sightlines to visitors, and natural light carries through. Spaces feel welcoming, not fortified.
- Airflow stays intact. The mesh doesn't trap air, so existing HVAC keeps working and you avoid costly mechanical upgrades.
- Retrofit-friendly. Designed for existing buildings, with less construction, less downtime, and lower total cost than a glass or wall-built vestibule.
- Safe exit, every time. ADA-compliant egress hardware and layout keep emergency exits clear.
- Matches your building. Custom powder-coat colors and custom-engineered layouts for any entrance.

Frequently Asked Questions
Adding a secure entry raises practical questions, from how it works with your existing building to what it means for daily traffic and emergency exits. Here are answers to the ones we hear most from schools, facility managers, and architects. Don’t see yours? Reach out using the form below and our team will help.
What's the difference between a vestibule and a mantrap?
A vestibule is a secure holding area inside the entrance where visitors wait to be verified. A mantrap adds a second set of doors so only one set can open at a time, preventing tailgating.
Can a vestibule be added to an older building?
Yes. Steel mesh enclosures are built for retrofits. Because they keep air moving, they typically avoid the HVAC and electrical upgrades a glass or framed-wall vestibule can trigger.
Will it make our entrance feel like a cage?
No. The woven mesh stays see-through, lets in natural light, and can be powder coated to match your building’s colors.
Can these be used outdoors?
Yes. Stainless steel mesh and aluminum framing are suited to exterior walkways and covered entries.
Do the doors meet ADA and egress requirements?
Each system uses ADA-compliant egress hardware and is designed so exits stay clear in an emergency.
Can the doors work with our access control system?
