Special screws with a wall multiplier of 5 times and a floor multiplier of 5 times to prepare for unexpected earthquakes!

Prepare for massive earthquakes with the 'GH5 screw,' which realizes high-strength walls with increased design flexibility, and the 'Nedazero 5 screw,' developed for seismic floors using a joist-less construction method.

Are there measures in place for an unexpectedly large earthquake? In the 2016 Kumamoto earthquake, wooden houses that were not very old collapsed, and two unexpected events occurred, including two instances of seismic intensity 7. 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 according to ministerial certification, and the Nada Zero 5 method, which has the highest floor strength ratio of 5 times according to 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), it creates a solid box-like structure (super monocoque structure) that can withstand significant seismic forces. Would you like to create 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! (Thick structural plywood 24mm, 28mm)
