Boston's healthcare campuses, university buildings, and dense urban office and residential towers generate sustained high-traffic volumes through commercial door openings. Multi-occupancy buildings with frequent public access, large student and patient populations, and complex egress requirements call for assemblies built to sustain heavy use across long service cycles.
Hollow metal doors for high-traffic Boston applications are typically specified at heavier gauges to resist deflection and wear in high-frequency openings. Hollow metal doors are available in 12- to 18-gauge steel. Hinge grade, closer specification, and exit device selection all contribute to long-term assembly performance in demanding environments.
Door closers are required on many fire-rated openings and are standard on high-traffic egress doors throughout Boston's institutional construction. Exit devices are required on many egress doors in high-occupancy commercial occupancies. Where the opening is fire-rated, exit devices must also be fire-rated and cannot be dogged down. Mortise locksets are commonly specified in high-traffic Boston applications, including healthcare corridors, university building entries, and high-occupancy restrooms. Mortise locks offer a longer service life than cylindrical locksets under heavy-use conditions and are repairable in the field.
When configuring heavy-duty assemblies in ProBuilder, door gauge, hinge grade, closer specification, and exit device selections are reviewed as part of the complete assembly workflow. ProBuilder supports selection of heavy-duty closer and hinge sets appropriate for high-traffic institutional egress doors. Consult with the project's design professional for final compliance verification.
