Softwood is wood from gymnosperm trees such as conifers. The term is opposed to hardwood , which is the wood from angiosperm trees. The main differences between hardwoods and softwoods is that the softwoods completely lack vessels (pores). [ 1 ]
The wood from conifers (e.g. pine) is called softwood, and the wood from dicotyledons (usually broad-leaved trees, e.g. oak) is called hardwood. These names are a bit misleading, as hardwoods are not necessarily hard, and softwoods are not necessarily soft. The well-known balsa (a hardwood) is actually softer than any commercial softwood.

Despite these disparities, softwoods and hardwoods share a cellular similarity – the majority of cells are non-living at maturity, even within the sapwood.
The main advantage is that softwood can be used for applications that require high durability. Durability class 1–3, according to European Standard EN 350-2, can be obtained out of non durable (class 5) softwood species. [13] The main disadvantage is that the strength is decreased as a result of the high temperatures.
