External type brace hardware.
● Seismic reinforcement hardware that can be installed directly from the outside without damaging the building's exterior walls, an external type of brace hardware. ● The material used is stainless steel (SUS304, 303). The concrete foundation and beam (girder) are connected with a 13mm thick stainless steel shaft. ● Since it acts on tensile force but not on compressive force, a cross-bracing installation is standard. ● Available in half-space (3 shaku) and one-space (6 shaku) sizes. The 6 shaku size is cut for a 4 shaku 5 sun opening.

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.
