Securing St. Louis Industry Since 1999
Gateway Perimeter Systems is a commercial & industrial perimeter security contractor serving the St. Louis metro. We engineer high-security fencing, automated gates, and code-compliant enclosures for the facilities that keep the region moving.
Licensed · Bonded · Insured
Missouri-classified commercial contractor with full general liability and workers' compensation coverage. OSHA-10/30 trained crews on every install.
A Defensible Line Around Every St. Louis Facility
Industrial sites and logistics centers face real perimeter risk — theft, trespass, and liability exposure. We close that gap with engineered enclosures that meet code the first time and hold up to industrial demand for decades.
From a 9-gauge fabric spec to a 40-foot cantilever gate, our work is documented, inspectable, and built to the standards your facility's auditors expect.
Three Principles
Built to Code, Not to Guesswork
Every spec is checked against St. Peters commercial building codes and OSHA perimeter standards before a post is set.
Industrial-Grade Only
We don't do residential picket. Our fabric, posts, and operators are specified to industrial load and access demands.
St. Louis Through & Through
Two-plus decades securing industrial zones and logistics centers across St. Peters, Earth City, and the metro.
Codes & Standards We Build To
Our specs are aligned with the authorities that govern commercial perimeter construction in the St. Louis metro.
City of St. Peters Commercial Building Codes
Setback, height, and material requirements governing commercial perimeter enclosures.
OSHA Perimeter Safety Standards
29 CFR 1926 Subpart C & M — fall protection, perimeter guarding, and gate operator safety.
