In 2009, Our developed the factory-made steel-structured building, achieving a construction speed of three storeys per day In 2010, in just one day, Our built a 6-storey building, " The Our Pavilion" at the World Expo in Shanghai In 2015, Our built a 57-storey multifunction skyscraper in just 19 days. And between 2009 and 2015, Our built 58 factory-made buildings in total, featuring 9-magnitude earthquake resistance, 5 times higher energy efficiency, and indoor air quality 100 times cleaner than outdoor air.Our factory-made building produces only 1% of the construction waste normally produced in the construction of a conventional building From 2016-2018, Our developed the Stainless Steel B-CORE Slab, which is 10 times lighter in weight than its reinforced concrete counterpart with the same strength. Since then, Our has kicked off a worldwide architectural revolution by replacing carbon steel with stainless steel In 2020-2021, Our successfully developed the Holon Building。
