Timber formwork is the most traditional formwork.
It commonly includes wooden board, wall tie accessories, Beams, etc.
Wooden boards are widely replaced by plywood boards. Plywood boards could be black film, brown film, red film, or anti-slip film with popular thicknesses in 9mm, 12mm,15mm,18mm, and 21mm.
Compared to traditional wooden boards, plywood boards have more high bending strength, little linear expansion coefficient, and strong nail holding, which solve the problems of leaking and rough surface during the construction process.
