AK/Apple Shuttering Plywood

AK/APPLE film faced shuttering ply is manufactured by using selected hardwood species with phenol formaldehyde resin (BWP grade) in high pressure hot press. AK/APPLE film faced plywood is a product for high end construction use. This plywood withstands the corrosive action of cement, water and sunlight as well as the distortion that occurs under exterior weather.
Due to its reliability film face plywood is used in so many applications, it is widely used in so many construction building projects, in vehicle industry and other exteriors as well. It is also used for shuttering purpose-especially with regard to surface films. They have improved resistance to abrasion, swelling, shrinkage, moisture penetration, chemicals, insects, fungi and borers.
It comes with 3 variants
  1. 18mm - 50kgs
  2. 12mm- 34kgs
  3. 12mm- 30kgs
