Fiber cement board is a stable performance and light weight building &decoration board used cement as major and natural reinforced, with the process of pulping, emulsion,forming, pressing,
autoclaving ,drying and surface treatment.The color is gray. With the sanding surface, thickness uniformity is better and grain is clearer. And because of the cement , the strength is higher, and water proof performance is much better.So fiber cement board is the highest quality product in domestic and foreign building materials market .
