Wood Types,Characteristics and Identification Guide

Wood is a fibrous and porous structural tissue of wood trees and other wood plans.This organic material made from natural cellulose fibers is found in their roots and stems,growing upward all the way to the tops of their canopy.Wood Structure and Properties SpringerLinkFor structural applications,wood is most commonly found as either sawn timbers,lumber,or glued laminated members (glulams).In the interest of economy and to permit using wood more efficiently,Wood Properties ArchitectureCourses.OrgAs with all materials,the design of wood structures is based on building code regulations.The durability of wood structures must also be considered and increasingly environmental considerations are influencing the choice of structural materials.Compared to masonry,concrete and steel,wood has environmental advantages.

Wood Properties - an overview ScienceDirect Topics

As a further illustration of differences in wood properties,the effects of variability in pit structure is quite striking.This is because,from a physiological perspective,some species have pit structures particularly well suited for more facile fluid transport,such as in the genus Pinus where fenestriform (i.e.,window-like) pit structures dominate ( Figure 58 ).Wood - Utilization of wood BritannicaThis section discusses the products of primary mechanical processing of woodroundwood products (e.g.,poles and pilings),sawn wood (primarily lumber),veneer,plywood and laminated wood,particleboard,fibreboard,and pulp and paper.It also discusses treatments (drying and preservation) that have been devised to improve the performance of wood in use and the chemical products that areWood - Properties of wood BritannicaWood - Wood - Properties of wood Sensory characteristics include colour,lustre,odour,taste,texture,grain,figure,weight,and hardness of wood.These supplementary macroscopic characteristics are helpful in describing a piece of wood for identification or other purposes.Colour covers a wide rangeyellow,green,red,brown,black,and nearly pure white woods exist,but most woods are
