At Ogawa Seisakusyo, we specialize in producing steel formwork for PC girders used in bridge construction. Our range includes various post-tensioned girders such as small girders; composite girders; and hollow girders to meet diverse needs. We also offer consultations for pre-tensioned girders; Wagen formwork; and PC board formwork.
Founded in April 1955, Ogawa Seisakusyo designs and produces steel formwork. Additionally, we provide equipment for bridge girder erection, various crane designs and constructions, inspection route designs and constructions, drainage equipment designs and constructions, anti-falling devices, repair and reinforcement materials, mechanical joints (CS joints), H-beam lateral transfer carts, general bridge components, anti-corrosion technologies, bridge nameplates, historical plates, and various other nameplates.
For instance, in crane design and construction, we can design and produce overhead cranes as well as gantry cranes. We also handle large crane designs and constructions. For inspection routes, we design and produce routes necessary for bridge maintenance, tailored to on-site needs. In corrosive areas, we use highly corrosion-resistant materials and anti-corrosion specifications, ensuring suitable solutions for the environment.
In terms of anti-corrosion technologies, we are developing new methods related to steel structures to contribute to the longevity of infrastructure. We can also propose anti-corrosion measures tailored to specific company needs. Some of our products can be customized based on material specifications, allowing for broad consultations even when existing products do not meet your company's needs.
It is common for enclosed steel formwork to make it difficult to see the concrete filling condition; however, they offer a specification that includes transparent panels on the steel formwork girder products, allowing visibility of the contents. This is suitable for situations where improved concrete filling accuracy is desired.
They have a track record of supplying post-tensioned formwork the Kyushu Shinkansen, Hokuriku Shinkansen, expressways, national and prefectural roads, as well as for overseas projects. Additionally, they have delivered special formwork projects such as extrusion formwork and PC slab formwork. They are a company strong in bridge construction projects.
Ogawa Seisakusyo engages in the production and construction of steel lattice formwork, which does not require removal or disposal. This is suitable for companies that emphasize environmental considerations, cost reduction, and speed. When selecting system formwork, it is essential to consider the type of construction project planned, as the appropriate formwork varies. When selecting a system formwork manufacturer, verify what types of constructions the manufacturer specializes in and ensure it aligns with your objectives.
We have selected formwork manufacturers from 55 companies found through a Google search for 'formwork panel manufacturers' as of February 1, 2022. The selection is based on the following criteria:
Based on construction examples, we have assessed the the number of construction cases handled, and categorized them into residential, commercial buildings, and civil engineering. We recommend those that simplify the installation process the most.
