In high-end buildings, commercial complexes, hospitals, hotels, and similar settings, the smooth operation of doors directly impacts user experience. Ordinary door closers often suffer from misalignment, oil leaks, or jamming in cold temperatures, while low-quality floor springs may even cause doors to swing uncontrollably under strong winds or impact, posing safety risks.
3H Building Hardware’s floor springs empower safety through technology, engineered for high-end building entrances, fire exits, and critical access points!
