Special screws with a wall ratio of 5 times and a floor ratio of 5 times to counter unexpected earthquakes!

Prepare for massive earthquakes with the 'GH5 screw,' which achieves high-strength shear walls and increased design flexibility, and the 'Neda Zero 5 screw,' developed for seismic-resistant floors without joists.

Are there measures in place for an unexpectedly large earthquake? During the Kumamoto earthquake in 2016, wooden houses that were not very old collapsed, and two instances of seismic intensity 7 occurred, highlighting two unexpected events. Simply adhering to building codes does not guarantee safety. In response, a construction method called 'Seismic 55 Method' has been developed to prepare for unexpected earthquakes! Seismic 55 combines the GH5 method, which has the highest wall strength ratio of 5 times as certified by the Minister, and the Nada Zero 5 method, which has the highest floor strength ratio of 5 times under the Housing Quality Assurance Act. By adopting the GH5 method for the outer walls and the Nada Zero 5 method for each floor (or roof), we create a solid box-like structure (super monocoque structure) that can withstand significant seismic forces. Would you like to build a higher-level seismic-resistant house with Seismic 55, which consists of walls and floors with a maximum strength ratio of 5 times each? 【Screw Features】 ■ GH5 Screw Achieves high-strength walls with increased design flexibility! ■ Nada Zero 5 Screw Developed for seismic-resistant floors using a no-joist method!
