High labour costs on construction sites increasingly require easier and faster formwork systems. Without exception, the number of components to be moved determines the shuttering times and ultimately the cost of construction. During the development of the TRIO system, PERI engineers placed great importance on reducing shuttering times. Thus a very versatile formwork system was created with a minimum of different components which meets and exceeds the demands of the modern-day job site in a simple way. Fewer individual components for faster forming. TRIO is the versatile panel formwork for all projects, on small building sites as well as for large-scale projects.
