Wooden playground: The wood used in our factory is imported rosewood, which is the best material for playgrounds in the market. This is a very heavy, dense and strong wood! Most of the products on the market are made of fir or Finnish wood. The disadvantage of these woods is that the density is not enough, the hardness of the wood is not enough, and the screw position is easy to loosen, which is not safe! We will also scrape 2 layers of environmental protection paint to protect the wood and increase the service life!
