The IS-KA Wooden Beam Formwork System, created with H20 wooden beams, steel straps, and plywood, is a formwork system widely used in construction sites today. In the system, the vertical H20 wooden beam elements are produced according to the EN 13377 standard. The formwork system can be adjusted to any height with the static design of the H20 wooden beams used in columns or walls (vertical load-bearing elements).

In the design of wall formworks, a maximum fresh concrete pressure of 50 kN/m² is considered, while in column formworks, a maximum fresh concrete pressure of 90 kN/m² is taken into account. Additionally, by changing the arrangement of the H20 wooden beams and the design of the steel straps, project work is possible according to high concrete pressures and pouring speeds.
