Upon completion, most artificial trees are placed outdoors, with their lifespan primarily related to the quality of the materials used and the internal structure of the tree. Xi'an Jinsen, a manufacturer of artificial trees, commonly uses glass fiber reinforced plastic (GFRP), GRC cement, and solid wood rod materials. Generally, outdoor trees are made of GFRP and GRC cement materials, which are dense, even, and robust with excellent texture, and are also environmentally friendly. The materials we use are highly stable, resistant to sun and cold, UV-proof, and have excellent fire resistance; they can withstand outdoor weathering very well, with an average lifespan of 10-15 years.
