Floor Spring Applications and Quality Requirements

Floor springs are widely used in commercial glass doors, self-closing office doors, department store entrances, hotel lobbies, and high-traffic public buildings. Due to high usage frequency and significant load-bearing demands, a floor spring must not only provide smooth door opening and closing — it must maintain stable closing performance and structural durability over extended periods of use.

The EN 1154 certification achieved by the S275 and S280 is a direct reflection of CHIEN CHIN's ongoing commitment to product design, structural integrity, and quality control.
