Excellent workability and maintenance-free! The pursuit was for the best balance of price and performance.
"GVA II" is a basic seismic control system that absorbs repeated vibrations using a uniquely developed phenolic resin. Even after experiencing repeated major earthquakes, it enables homes to remain livable. It disperses and absorbs seismic energy, minimizing deformation of the home. The newly designed arm, integrated with a friction damper, features a simple structure that does not interfere with the connections (junctions between columns and foundations/beams) or intermediate columns. Since there is no need to consider interference, it can be installed either on the inside or outside when installing hold-downs. 【Features】 ■ Absorbs repeated vibrations with phenolic resin ■ "Diamond structure" that minimizes deformation of the home ■ Simple structure that is easy to design and construct ■ Effective seismic control with minimal installation *For more details, please download the PDF or feel free to contact us.
