Locally procured cedar or pressure treated posts are required. Rails are horizontal members which capture the panel body material. The body material for the Yucatan Bamboo Fence is formed of compressed bamboo branch material. Pickets are vertical members which do not support the panel and exist between the posts. They may capture the body material, but are always a part of the artistic design.
Whole poles are full round poles used just as they are harvested, cured, and cleaned.
Half rounds are formed by ripping the whole poles from end to end. Half rounds are often used as pickets and rails. Treatment in the case of the Yucatan Bamboo Fence system post is a saturation of the woody material with pentachlorophenol to resist insect and rot attack. If you thought that the stuff above was boring, the following will have you asleep in 30 seconds. The Maya fence panel has three or more horizontal rails on each side.
