Preservative-treated pinewood is mildewproof, anticorrosive and mothproof, with the long durability and environmental protection as its fine performance. It has become an important material for landscape construction for the wide pine material sources, low price, less deformation, moderate density, good fl exibility and strength, fine texture and good integration with the natural environment. On the basis of introducing pinewood species, preservatives and production process of preservative-treated pinewood, this paper focuses on the application of preservative-treated pinewood used in log cabin, pavilion, service buildings and other garden timber architecture, as well as roads, platforms, bridges, rails, gallery frames, pergolas and other opuscules.
