Beson FS concrete shuttering plywood is made of high density dipterocarpus species assembled in auto assembly line for dimensional accuracy, bonded under high temperature and pressure with unextended exothermic synthetic resign in high-capacity densified hot press (2000n) with as minimum compression 30%, used for concrete purpose. Manufactured with select hardware, it withstands the loads and forces encountered during the pouring of concrete and vibrations. It is the result of continuous experiments undertaken at our modern laboratories to meet the growing demand from the construction industry for highly durable concrete shuttering plywood.
