Extra-D Decking (outdoor decking) Extra-D? Bamboo Decking is a solid, high density decking board, made from compressed bamboo strips. Bamboo is highly dense and strong. Extra-D? Bamboo Decking is heat treated and pressed. The unique manufacturing process provides the decking a very hard product with an excellent hardness, stability and highest durability. Extra-D? Bamboo Decking is so dense and rots proof which is not easy to be bending or cupping, like most wood planks, also does not split or crack with time in opposition to wood planks. The decking is available in 4 ribbed surface types and 2 side shapes. The special hidden fastener system allows for quick installation with HuiHuang? fasteners. Like any untreated tropical hardwood species, when exposed to outdoor circumstances, Bamboo Decking will turn grey over time creating a very natural look. http://www.ajhhbamboo.com/
