Fiber cement board dimensions is a stable performance and light weight building & decoration board used cement as major and natural fiber 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 waterproof performance is much better. So fiber cement board is the highest quality product in the domestic and foreign building materials market.

When hand carrying single panels, they must be carried on edge with the short side held vertically.
B. Deliver, store and handle materials to prevent breakage, warping or damage by water.
C. Acclimatize materials by storing on site not less than three days before installation.
D. Materials to be stored indoors on leveled dunnage not exceeding 32" on centers. If temporarily stored outdoors, boards must be elevated above ground, and protected from the weather with waterproof covering.
