Timber in Construction

Hello Engineers welcome back to Expertcivil.com, let’s know all about  the timber, which are used as a construction materials.

In this post the following topics will be covered, 

  • What is timber
  • Used of timbers
  • Classification of timbers

Do you know all about the common timbers in India? if no then please go and read our recent articles,

What is Timber?

As we know that, Timber denotes wood, which is suitable for building or carpentry or various other engineering purposes like for construction of doors, windows, roofs, partitions, beams, posts, cupboards, shelves and many mores.

We seems many things in daily life which is made by timber for example, wooden gate, window partition walls etc. 

What is Timber Used for?

As discussed, timber or woods is generally used in every construction or carpentry works like, construction of bridges, piles(Wooden piles) Scaffolding, frame work, temporary structures etc.

Classification of Trees 

Depending upon their mode of growth trees may be divided in the following two categories.

  1. Endogeneous trees
  2. Exogeneous trees

Endogeneous Trees

These trees grow inwards and fibrous mass is seen in their longitudinal sections. Timber from these trees has very limited engineering applications Ex: bamboo, cane , palm etc 

Exogeneous Trees

These increases in bulk by growing outwards and used for engineering purposes. Exogeneous trees are further sub-divided into two groups 

  • Conifers 
  • Deciduous
Conifers Trees

These trees having pointed, needle like or scale like leaves and yield soft wood. this tree is also known as evergreen tree.

Deciduous Trees

The trees having flat broad leaves and leaves of those trees fall in autumn and new ones appear in spring season.

Timber for engineering purpose is mostly derived from deciduous trees. These trees yield hard wood. 

Example: ash, beach, oak, sal, teak, shishum and wallnut.
