All you need to know about American Softwoods

摘要

American Softwoods has published a new brochure to provide importers, architects and specifiers with information on the range and diversity of American softwood species, and which are best suited to a wide variety of different applications. A Guide to American Softwood Species presents details of the botanical names, properties and uses of the commercially important American softwood species. Physical and mechanical properties are described and each species is given a durability rating according to BS EN 350-1 (European Durability Classes). Architects and structural engineers can also refer to tables which list and compare mechanical properties, such as the specific gravity, modulus of rupture, modulus of elasticity and compressive strength of American softwood species with the properties of European species such as Scots pine (Pinus sylvestris), Whitewood (Picea abies) and Sitka spruce {Picea sitchensis). Southern yellow pine and Douglas fir perform particularly well on these measures.
