The TOUGHNESS series is a product line that pursues high robustness to withstand the building winds and sudden gusts unique to cities.
Wind tunnel tests by external organizations have demonstrated wind resistance that prevents damage even in environments with wind speeds of 30m/s. Our unique design, which reinforces the structure, has achieved reliable quality that can be used with peace of mind even on windy days.
* "Strongest" refers to our company's wind resistance standard, which has cleared wind speeds of 30m/s in wind tunnel tests conducted by external organizations.
