The "NAV-G Method (UV Specification)" allows for the formation of a highly transparent FRP on concrete surfaces by applying and impregnating acrylic resin adhesive onto a special fiber sheet, enabling the observation of new crack occurrences and serving as a new method for preventing peeling. It ensures transparency that is not found in conventional peeling prevention methods, with expectations for sustained visibility over the long term. 【Features】 ■ Visibility ■ Shortened construction period ■ Weather resistance ■ Mechanical properties ■ Applicability in construction *For more details, please refer to the PDF materials or feel free to contact us.

"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.

All of our factories have received registration for the new JIS certification, promoting thorough standardization and quality management, and have obtained ISO 9001 and 14001 certifications. The factory products manufactured through well-equipped facilities and consistent production processes are always of high quality and high performance. The introduction of new equipment, such as the automatic steam curing management system, contributes to the development of social infrastructure and economic efficiency. The main manufacturing items include civil engineering, bridges, underground structures, and building components, with factories located in "Kanto," "Shiga," and "Fukuoka." 【Main Factory Equipment】 ■ Batching Plant ■ Plant Control Room ■ Production Line (Reinforcement Assembly) ■ Tensioning Device ■ Steam Curing Device ■ Steam Curing Management System *For more details, please refer to the PDF materials or feel free to contact us.

The "floating pier" consists of a main PC floating body (pontoon), a connecting bridge that links the shore to the pontoon, a bridge that connects pontoon to pontoon, and mooring lines that anchor the pontoon. Since the floating pier rises and falls with the tide, there is no change in height difference with vessels, making it easy to load and unload cargo and passengers. Additionally, the PC floating pier is highly stable due to its weight, enhancing convenience. In recent years, there have also been examples of larger constructions. 【Features】 ■ Capable of constructing large floating bodies ■ Can reduce the height of the floating body ■ Controls cracking ■ Uses high-quality concrete ■ Superior durability compared to reinforced concrete *For more details, please refer to the PDF materials or feel free to contact us.

"JB-HABIS" is an inspection path for bridges made from high corrosion-resistant steel material ZAM(R) in the form of steel plates, shapes, and pipes. Performance verification tests and impact loading tests in accordance with NEXCO testing methods have been conducted on the walkway beams and handrails, confirming sufficient safety. Additionally, since the materials are processed (cut and drilled) by the material manufacturer and assembled solely with bolt connections, welding during production is unnecessary. This eliminates distortion due to thermal effects during manufacturing, allowing for the provision of products with high dimensional accuracy. 【Features】 ■ Excellent corrosion resistance ■ Uses ZAM(R) treated with pre-galvanization for rust prevention ■ No post-galvanization rust prevention treatment required during manufacturing ■ High dimensional accuracy and lightweight ■ Low lifecycle cost * "ZAM(R)" is the product name for a molten zinc-aluminum (6%)-magnesium (3%) alloy coated steel sheet developed by Nisshin Steel Co., Ltd. * For more details, please refer to the PDF document or feel free to contact us.

Transparent concrete coating. A coating that allows the concrete surface to be seen through. The 'NAV-G method (UV specification)' enables the formation of a highly transparent FRP on the concrete surface by applying and impregnating an acrylic resin adhesive onto a special fiber sheet, allowing for the observation of new crack occurrences and other issues, making it a new type of peeling prevention method. It ensures transparency that is not present in conventional peeling prevention methods. Long-term visibility is expected. 【Features】 ■ Visibility ■ Shortened construction period ■ Weather resistance ■ Mechanical properties ■ Applicability in construction *For more details, please refer to the PDF document or feel free to contact us.

The SCBR method (Smart Connected Bridge) is a construction technology for concrete bridges that offers benefits such as alleviating labor shortages, reducing on-site work, and ensuring high quality through factory production. By using this method, it is possible to replace deteriorated RC hollow slab bridges in a short period while utilizing existing bridge piers, such as two-column types. It is also adopted to reduce noise through jointless bridge construction and simplify maintenance management. 【Features】 ■ Shortened construction period ■ Reduced regulations and costs ■ Easier maintenance management ■ Preservation and consideration of landscape, etc. *For more details, please download the PDF or feel free to contact us.
