A proposal-type solution that shapes your ideas through consistent production. Leave the circular formwork, system formwork, and shoring plans to us.

Our job is to give "shape" to concrete that would otherwise flow away as it is. We can consistently plan, design, and produce everything from circular (arch) formwork, irregular formwork, and special formwork to support materials, large formwork, and system formwork necessary for civil engineering and construction projects. We will propose solutions to shorten construction periods, reduce costs, and address the shortage of skilled workers. [Examples of Projects] ■ System Formwork ■ No-Separation Method ■ Arch Truss Support ■ Custom-Machined Formwork *For more details, please download the PDF or feel free to contact us.

basic information

○ System Formwork A construction method where formwork is assembled in large sections and installed using a crane. This is effective for shortening construction periods and addressing labor shortages. We handle everything from formwork materials to shoring components in-house. We can provide assembly guidance at construction sites anywhere in Japan. ○ No-Separators Method This method does not use separators (formwork support materials) during the construction of the formwork, relying solely on the strength of the steel to withstand concrete pressure. Since there are no separators, there is no risk of water leakage, and the finish is also beautiful. ○ Arch Truss Shoring By bending steel into an arch, we can easily secure complex structural formwork. We will discuss and plan the shoring design with you. ○ Real Wood Grain Processed Formwork This allows for the pouring of concrete with a beautiful wood grain finish. We will plan the project drawing on our past achievements and experience.

Koyo Shokai Co., Ltd. is a comprehensive manufacturer of concrete formwork used in various construction projects. We possess the craftsmanship to produce complex structures such as circular formwork, arched formwork, and special formwork. Additionally, we have our own metalworking department, allowing us to provide one-stop planning, design, and manufacturing services for various support materials, truss materials, and system formwork, from formwork to support structures. We manufacture and sell formwork for construction panels, bridge piers, wagons, box culverts, shafts, tunnels, and various trusses. In recent years, to meet the diverse needs of the field, we developed a transparent resin concrete formwork called "Miere Form" (NETIS registration number KK-080044-VE), and in December 2019, we re-registered it as a new technology under the name "Clear Form" (NETIS registration number KK-190028-VE), which allows for free design and offers proposals for creating safe and secure structures. Furthermore, in 2023, we developed a permeable board formwork called "Aqua Toll" (NETIS registration number KK-230041-A). Koyo Shokai provides not only simple formwork design but also comprehensive planning for formwork and support structures tailored to the needs of the site.
