The udeveloped area of the film faced plywood is the contact area between the formwork and the concrete. The developed area of film faced plywood is 2 to 3 times of the building area.
The developed area of the film faced plywood is the contact area between the formwork and the concrete, including the area of the bottom of the slab and the side formwork. The developed area of the formwork of the slab is the sum of the area of the bottom formwork and the partial side formwork; the beam formwork is installed on three sides, the bottom and the sum of the three-sided formwork; and the surface area of the concrete column and wall is the sum of the area of the four sides.
After calculated the developed area of the film faced plywood, it is necessary to measure the usage of the film faced plywood according to the type of the film faced plywood and the number of turnover times.
