グランデータ Company Profile

The GD seismic reinforcement system improves the seismic resistance of wooden houses from both the outside and inside, enabling low costs and short construction periods with minimal burden on customers.

Since shortly after the Great Hanshin-Awaji Earthquake, our company has been working on the seismic retrofitting of existing wooden houses, and we are currently involved in numerous seismic assessments and retrofitting projects. The GD seismic reinforcement system was developed to alleviate the burden on homeowners and promote the seismic retrofitting of houses, and we manufacture and sell products such as GD Walls, GD Braces, and GD Anchors.
