In early 2025, a premium residential compound in Shanghai's Minhang District reached out to our team with a specific challenge. The property management had just completed a major lobby renovation featuring warm bronze tones and natural stone finishes. The existing stainless steel turnstile at the main entrance — functional but visually jarring — clashed badly with the upgraded interior. They needed a replacement that could handle over 2,000 daily transits while matching the architecture.
After three rounds of on-site consultation and finish sampling, we delivered a fully customized swing barrier gate in an antique bronze finish, with an embedded facial recognition terminal. The installation went live in March 2025 and has been running continuously since.
The property management team laid out their requirements during the kickoff meeting:
Standard powder coating could not reproduce the aged bronze look the client wanted. Our finishing team developed a multi-layer process: a dark primer base, followed by a hand-applied bronze metallic coating, then a chemical patina treatment to create controlled oxidation patterns, and finally sealed with an outdoor-grade clear protective coat. The result is a surface that looks like aged architectural bronze but withstands UV exposure and rain without further uncontrolled oxidation.
Three sample panels were produced and shipped to the client for on-site comparison against the lobby panels under different lighting conditions — morning, noon, and evening. The final formulation was locked in after the client signed off on the noon-light match.
The swing barrier gate was built around our SWG-800 series mechanism, chosen for its 0.6-second opening speed and proven track record in high-traffic environments. We integrated a binocular IR facial recognition terminal mounted at 1.45m height, calibrated for the average resident height range. The terminal connects to the community's existing property management database, with local edge storage for offline recognition when the network is interrupted.
Passage logic was programmed in three modes: residents trigger gate opening immediately upon face match; registered visitors get one-time access within a time window after the host approves via the community app; delivery personnel are routed to a separate side lane with QR code verification.
| Specification | Detail |
|---|---|
| Mechanism Model | SWG-800 Swing Barrier Gate |
| Cabinet Material | 304 Stainless Steel (1.5mm thickness) |
| Surface Finish | Custom Antique Bronze (multi-layer hand-applied) |
| Opening Speed | 0.6 seconds |
| Facial Recognition | Binocular IR camera, 99.7% recognition rate |
| Passage Width | 650mm (standard), adjustable to 900mm |
| Ingress Protection | IP54 rated for outdoor use |
| Fail-Safe Mode | Automatic swing-open on power loss or fire signal |
| Daily Capacity | 2,000+ transits |
Installation took three working days. Day one covered mounting plate preparation and cable routing; day two was mechanical installation and power-up; day three focused on facial recognition calibration, passage logic testing, and integration with the fire alarm relay.
We ran a 48-hour continuous cycling test before handover: the gate executed over 10,000 open-close cycles without a single mechanical fault. Recognition testing across 50 volunteer residents achieved a 99.2% first-pass rate under varying lighting — morning sun, overcast, and lobby artificial light after dark.
This project highlights what in-house manufacturing control actually means on a custom job. The finish sampling alone required close coordination between our metal fabrication, coating, and QC teams — something a trading company relying on third-party suppliers cannot realistically manage within a reasonable timeline. Every step from sheet metal cutting to final assembly and testing happened under one roof, which let us iterate on finish samples in under two weeks.
The antique bronze finish has since become a repeat request from other clients in the hospitality and luxury residential sectors. We now keep the formula on file as a standard customizable option.
