Commercial & Multifamily Security Gates in San Antonio
Duncan’s Services designs, builds and installs security gates, controlled-entry doors and access systems for apartment communities, businesses, schools and shared facilities across San Antonio and the Hill Country. We combine custom metal or wood construction with practical keyless-entry options selected for the people who use the property every day.
SECURITY SOLUTIONS FOR APARTMENTS AND COMMERCIAL PROPERTIES
Mailbox-area security gates
Custom steel gates and enclosures create a controlled barrier around apartment mailbox areas while keeping daily access convenient for authorized residents.
Pool and shared-facility access
Pedestrian gates and keyless locks help property managers control entry to pools, courtyards, amenity spaces and other shared areas.
Vehicle gates and access control
Options include automatic swing and sliding gates, LiftMaster operators, keypads, remotes, smartphone controls, photo eyes and free-exit vehicle sensors.
FLEXIBLE ENTRY FOR RESIDENTS, STAFF AND VENDORS
Depending on the entrance and environment, access options may include keypad codes, fingerprint entry, keycards, mechanical push-button locks or app management. Keycards can be a practical choice for residents who prefer not to remember a code or use a fingerprint reader.
SAN ANTONIO APARTMENT MAILBOX SECURITY PROJECT
One apartment community had three open mailbox areas where unwanted visitors could walk directly up to residents’ mailboxes. Duncan’s Services built and installed custom security-gate enclosures with keypad, fingerprint and keycard access. The project added a physical barrier while preserving convenient entry for residents, including older residents who preferred keycards.
