Overcoming the weaknesses of concrete! Copper material, which has 5 to 6 times the strength of rebar, secures the concrete.
"Prestressed Concrete (PC)" literally means "concrete that has been pre-stressed." PC structures are composed of concrete members reinforced by applying compressive stress with high-strength steel, resulting in lightweight, high-quality, and durable structures. Our company is committed to the development of construction techniques for the "Prestressed Concrete Method." We have a wide range of expertise in various structures, including bridges, buildings, containers, port structures, and underground structures, and we have constructed many PC structures. [Our Achievements] - We have handled over 20,000 PC structures. - We have constructed a wide range of projects, from small to large scale. - We have built many PC structures, including bridges, buildings, containers, port structures, and underground structures. - In addition to construction, we have developed various technologies for investigating, repairing, and reinforcing PC structures to protect and utilize them. *For more details, please refer to the PDF materials or feel free to contact us.
