2.asbestos free 
3.Durable 
4.can be used for exterior
5.Wooden Grained
6. Reinforced Fiber
7. Cement Board
Wood grain fiber cement siding board is a plank for building external cladding application that the featuresis the cedar finishing.
wood grain fiber cement board are high quality building materials. The board contains inorganic raw materials
such as cement, silica powder and reinforced cellulose fiber as the main materials.
HBD boards are autoclaved to become stable product.
HBD fiber cement board does not contain any of asbestos, however, it has strong bending strength like those with asbestos.
HBD fiber cement board can be applied not only for the interior use but also for the outdoor wall system. It has low water absorption rate and high impact resistant ability.
These good advantages make it suitable for any purposes of applications.
