Five years ago, Hsi Hu Yuan, a prestigious apartment complex in Neihu, Taipei, called Waterson for help because their main gate was stuck by its rusted hinges. After fitting Waterson self-closing hinges, their gate regained the smooth closing with self-closing ability.Three years later, Waterson launched a new hydraulic model with buffering capacity. This customer immediately contacted us again for purchase.While our team was on the premises, something interesting caught our eyes. The original Waterson hinges were still functioning normally like day 1. Certainly the hinges were mildly stained by dust and dirt, but it kept deliver stable closing power as it should do.To remedy the noise from slamming gate, we replaced one hinge with a new hydraulic model. The customers were all satisfied with the soft close effects.
