shaped load - carrying structures are fabricated using bamboo linear fibers with a compatible bonding material and synthetic polymers such as polyesters , epoxies , and polyolefins . the structures are manufactured by coating at least one of bamboo culms , split bamboo culms , bamboo fiber tape , or prepared bamboo fibers with a bonding material to produce a core . the core is then combined with a polymer matrix and extruded or molded to form a structure having the desired shape . the structures compare favorably with wood , steel , and concrete regarding strength , longevity , price and ability to withstand earthquakes . the structures may be used as beams , columns , telephone poles , and marine piles .
