The following is a list of Japanese manufacturers that specialize in plastic formwork for concrete, primarily used in residential and commercial building construction. Plastic formwork is lightweight, easy to handle, and resistant to corrosion, even when exposed to water.
When choosing a formwork manufacturer, it is important to consider not only the type and purpose of the building, such as residential construction, commercial buildings, or civil engineering projects, but also whether the formwork system is easy to assemble and can be reused. Assess whether they provide formwork that meets your specific needs.
