Sanwa Shutter Corporation (Headquarters: Itabashi-ku, Tokyo / President: Meiji Takayama) will expand the design range of its “Water Guard Waterproof Shutter” and release it on March 27th.
The “Water Guard Waterproof Shutter,” launched in October 2014, is a panel-type shutter with waterproofing capabilities that can withstand submersion up to 3 meters. While normally used as a management shutter, it has been adopted as a waterproofing facility to prevent inundation into buildings during floods caused by large typhoons or sudden torrential downpours at entrances of subways, financial institutions, factories, drainage pump stations, and other locations.
To better meet customer needs, the design range has been expanded while maintaining the highest waterproofing performance (Ws-6). The previous maximum dimensions of Wmax 6,000mm and Hmax 4,000mm have been increased to Wmax 8,000mm and Hmax 5,250mm. This allows installation in locations requiring high waterproofing performance with larger openings, such as entrances for large special vehicles at fire stations and waste treatment facilities, or large equipment搬入口 (equipment loading/unloading entrances).
Sanwa Shutter Corporation provides customers with various products and services related to disaster prevention and mitigation, including waterproofing, windproofing, fireproofing, and earthquake resistance. We will continue to contribute to society by providing safety, security, and comfort to everyone through our efforts in disaster prevention and mitigation.
