We installed handrails on stairs in Ichikawa City, Chiba Prefecture. Since the handrails were to be installed later, we first installed the support frame for the renovation, then created a base to prevent the handrails from coming off and then installed the handrails. We also installed an I-shaped handrail at the base of the stairs to allow smooth descent. The customer, who had previously had difficulty going up and down the stairs, was very pleased.
