Applications/Examples of results

【Feature 1】 - Fewer components (approximately 30 fewer than conventional methods using steel pipes and supports) ↓ <Advantage> Less labor-intensive (Example: A difference of 5 minutes per square meter = 50 minutes difference for 10 square meters) ↓ <Benefit> Contractors can increase their productivity accordingly 【Feature 2】 - Can learn the assembly procedure in 2 to 3 hours ↓ <Advantage> Requires fewer skilled workers and technicians ↓ <Benefit> Contractors can use newcomers and trainees for assembly and demolding, stabilizing the process for the main contractor For specific implementation examples, please refer to the related YouTube video. At Perry Japan, we conduct product exhibitions of system formwork, study sessions, assembly experiences, and product seminars at our Ibaraki stockyard, based on the concept of "Listen, See, Touch/Ride, and Assemble" to meet customer needs. *We welcome inquiries regarding applications and case studies.

Detailed information

(Performance Introduction) "New Construction of a Paid Nursing Home in Ie Island" In the construction of a nursing home on Ie Island, Okinawa, our lightweight resin formwork (DUO) and aluminum slab formwork (GRIDFLEX) were used.
RC 1-story building Construction area: 1,364 square meters Total floor area: 1,359 square meters Formwork construction area: Foundation part approximately 1,500 square meters, above ground floor: approximately 3,500 square meters (total: approximately 5,000 square meters)
The needs on site were mainly identified as the following three points: reduction in the number of materials, reduction in the number of workers, and a higher work efficiency. To address these issues, Perry Japan proposed the lightweight resin formwork system (DUO) and the aluminum slab formwork (GRIDFLEX), which were newly introduced to the Japanese market in 2019. These solutions contributed to the reduction of materials, shortening of work time, and labor-saving.
Customer comment: "The number of formwork components per square meter has been halved, simplifying construction, improving work efficiency, and leading to a reduction in construction time. The amount of wood used has decreased compared to traditional methods, achieving resource conservation. The amount of materials transported to the site has decreased, reducing transportation costs. Since there is no need for tasks such as steel compaction and nailing, noise has been reduced."
By using the lightweight resin formwork system (DUO) and aluminum slab formwork (GRIDFLEX), it is possible to reduce material transportation costs, decrease the number of workers, and cut unnecessary expenses through labor-saving measures.
