We will protect the precious lives and property of the residents and bring new vitality to the building.
The "ORS External Frame Method" is a construction technique that enhances the seismic resistance of buildings by creating a seismic frame using columns and beams (precast components) manufactured in a factory and newly installed outside the building. This method combines the advantages of precast components and prestressed concrete, allowing for high seismic performance in buildings. Since the construction is completed on the exterior of the building, residents can continue their daily lives while the work is being done. Additionally, it eliminates the need for relocation compensation for residents, reducing costs and effort. 【Features】 ■ Can withstand large earthquakes ■ Allows continued use of the building during construction ■ Can shorten on-site construction time ■ Can change the exterior appearance ■ Minimally impacts the internal space *For more details, please refer to the PDF materials or feel free to contact us.
