This document provides an overview of wood, including its classification, properties, and common types. It discusses that wood is a porous, fibrous material found in trees and plants. Wood is classified as either natural wood or engineered wood. Natural wood includes softwoods and hardwoods. Softwoods grow more quickly and are less dense, while hardwoods have a more complex structure and are denser. Common softwood types include pine, cedar, and redwood, while common hardwood types include oak, maple, mahogany, cherry, and rubber wood. The document outlines characteristics and uses of different wood types.

Characteristics
HARD WOOD VS SOFT WOOD
SOFT WOOD
 Cheap comparative to hard wood
 Faster rate of growth
 Lower density
 Softer than hardwood
 Light in color
 Light in weight
 Poor fire resistant
 Strength in tension but week in sheer
HARD WOOD
 Hardwoods have a more complex structure
than softwoods
 Dark in color
 Expensive
 Slower growth rate
 Higher density
 Heavy in weight
 More fire resistant than soft wood
 Strong in compression and tension

9. Hard wood
 Hardwood is wood from dicot angios
perm trees
 The term may also be used for the
trees from which the wood is derived;
these are usually broad-leaved.
 In temperate and boreal latitudes they
are mostly deciduous, but in tropics
and subtropics mostly evergreen.
 Hardwoods are not necessarily
harder than softwoods.

Oak
 Light in colour.
 Heavy.
 Ring porous.
 Open grain.

Types of hard wood
Maple
 Maple is so hard and
resistant to shocks that it is
often used for bowling alley
floors.
 Its diffuse evenly sized
pores give the wood a fine
texture and even grain.
 Maple that has a curly
grain is often used for
violin backs.
 Burls, leaf figure, and
birds-eye figures found in
maple are used extensively
for veneers.

Types of hard wood
Rubber wood
 light color
 Medium density
 Usually from the tree of rubber
 plantation
 Advertised as eco-
friendly wood Because It
is not grown specially for
timber but instead have
timber as by product

15. Soft wood
 Softwood is wood from gymnosperm
trees such as conifers
 Softwood is the source of about 80%
of the world's production of timber
 Softwoods are not necessarily softer
than hardwoods
 The woods of long leaf pine, douglas
fir, and yew are much harder in the
mechanical sense than
 several hardwoods
