Company Overview
For over 60 years since its establishment, Sanwa Shutter Corporation has been supporting towns and lifestyles by providing a wide range of metal fittings mainly for openings including shutters, doors, partitions, toilet booths, and automatic doors.
Our mission is to “offer products and services that provide safety, security, and convenience to further contribute to the prosperity of society.” We are actively engaged in the development of “disaster prevention products” to protect human lives from natural disasters such as earthquakes, typhoons, and heavy downpours, which have become increasingly severe in recent years.
Climate Change Impacts
The percentage of "strong" typhoons with the maximum wind speed of 33 m/s or higher has been increasing since 2000. Global warming projections towards the end of the 21st century (Note 1) indicate that the number of very strong tropical cyclones with the maximum wind speed exceeding 45 m/s is expected to increase as global warming progresses.
It is important to prepare in advance to prevent the wind damage by strong winds to buildings and human lives.
Adaptation Initiatives
In recent years, strong typhoons have been occurring every year, causing flooding damage due to heavy downpours (Note 2) and frequent damage to buildings and other structures due to windstorms.
In 2018, Typhoon No. 21 crossed the Kinki region, recording a maximum instantaneous wind speed of 58.1 m/s (Kanku Island), causing 14 deaths and approximately 98,000 damaged residences. The East Japan Typhoon (Typhoon No. 19) in 2019, recorded a maximum instantaneous wind speed of 57.5 m/s in Chiba Prefecture, causing many roofs to be blown off from houses.
In this context, countermeasures against typhoons are becoming increasingly important, and better wind resistance is required not only for detached houses and apartments, but also for large openings in commercial facilities, factories, and airports, and openings in coastal facilities, and large distribution warehouses.
We sell our Wind Guard Series (Figures 1-7), which offers the industry's top class wind pressure resistance performance for both new and existing shutters, and have been highly evaluated by our customers.
Effects / Expected Benefits
In order to prevent damage to buildings caused by strong winds, it is important to be prepared in advance. Our Wind Guard Series can be used for a wide range of applications, from high-strength heavy shutters for large openings with high wind pressure resistance, to reinforcement materials that can be installed on existing lightweight shutters. As preparation for typhoons has become more important than ever, our products are expected to contribute to disaster prevention and disaster mitigation through BCP measures in advance.
