As part of the 350 million pounds garden project, a 50-meter-tall artificial "super tree" is lighting Singapore's night sky. These super trees have huge concrete trunks and several thousand rebar branches and canopies. These artificial trees have solar panels, suspended gardens, and rain collectors. Artificial trees can also display plants from all over the world. Corrugated Steel Pipe,Spiral Steel Pipe,Spiral Welded Steel Pipe Wanlei Steel Pipe Co., Ltd. , http://www.tjsteelpipes.com
