Thickened profile Aluminum Alloy Floor Spring Door

The aluminum alloy floor spring door uses a hydraulic floor-mounted pivot mechanism as its primary operating hardware, enabling the door to swing in both directions from a central pivot point and return automatically to the closed position after each use — without any manual latching or closing effort from the user.

The hydraulic floor spring provides a consistent, controlled closing speed that brings the door quietly and smoothly to the fully closed position without slamming, regardless of how quickly the door is released. This controlled-close characteristic significantly reduces noise impact in high-traffic environments and eliminates the risk of door-slam injury. Single-leaf and double-leaf configurations are both available, with tempered glass infill providing a visually open, welcoming appearance for entrance applications.

Multi-layer sealing at the frame perimeter provides effective sound and thermal isolation when the door is in the closed position. The floor spring mechanism is rated for high daily cycle volumes and is designed for long service life under the operating conditions typical of commercial entrances. This door is the standard specification for office building lobbies, hotel and hospitality entrances, retail stores, shopping center access points, and other high-footfall commercial spaces where hands-free, self-closing operation is a functional requirement.
