Introducing a shelter with a staircase for elevation that can be installed in places like gardens without roofs!
The 'Square' is an underground yard-type residential disaster prevention shelter. It uses 6mm thick steel exterior wall panels and 150mm wide U-shaped steel reinforcements. By burying the corrosion-resistant coated shelter underground, it creates a safe underground space completely isolated from outside air. Additionally, it prevents the intrusion of hot air and radioactive materials into the shelter with a blast valve and an overpressure relief valve that control the isolation from outside air. 【Features】 ■ Air filtration system ■ Power jack ■ Folding two-tier bed ■ Folding sofa ■ Underfloor storage *For more details, please refer to the PDF materials or feel free to contact us.
