Market Forms of Timber
Timber is a versatile and widely used construction material in civil engineering due to its strength, durability, and sustainability. It is derived from trees and is a renewable resource, making it a popular choice for building projects. Timber is available in various forms in the market, each with its own unique characteristics and uses. In this article, we will discuss the market forms of timber and their properties.
1. Solid Timber
Solid timber is a basic form of timber obtained by sawing logs into rectangular or square shape. It is the most commonly used form of timber in construction. Solid timber is further classified into three types – softwood, hardwood, and engineered wood.
a) Softwood: Softwood includes timber from coniferous trees such as pine, spruce, and fir. It is easy to work with, lightweight, and has good load-bearing capacity. Softwood is commonly used for the construction of frames, walls, and roofs.
b) Hardwood: Hardwood is obtained from deciduous trees such as oak, teak, and mahogany. It is strong, durable, and has a high resistance to wear and tear. Hardwood is used for flooring, furniture, and decorative purposes.
c) Engineered Wood: Engineered wood is a composite material made by binding or fixing two or more wood layers together. It is more stable and has better strength compared to solid wood. Engineered wood is often used for beams, columns, and trusses in construction.
2. Laminated Timber
Laminated timber, also known as glulam, is made by gluing together several layers of solid timber with the grains parallel to each other. This process increases its strength and stiffness, making it suitable for long-span structures such as bridges and roof beams. Laminated timber is also used for architectural purposes as it can be shaped into various curved forms.
Plywood is a manufactured wood panel made by bonding together three or more thin layers of wood veneer with the grain of each layer at right angles to each other. This cross-graining technique results in a strong and stable sheet that does not shrink or warp. Plywood is widely used in flooring, roofing, and wall sheathing.
4. Particle Board
Particle board is a panel product made from wood particles such as wood chips, sawdust, and wood shavings. It is manufactured by mixing these particles with resin and pressing them into a sheet under high heat and pressure. Particle board is used in furniture, flooring, and as a base for other wood veneers.
5. Medium-density fibreboard (MDF)
MDF is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres. These wood fibres are then combined with wax and a resin binder to form a strong and dense panel. MDF is widely used for furniture, cabinets, and mouldings.
In conclusion, timber is available in various forms in the market to cater to different construction needs. Each form has its own unique properties and applications. As a civil engineer, it is essential to select the right form of timber based on the specific requirements of a building project to ensure its structural integrity and longevity.
In conclusion, timber is a highly versatile and valuable resource that is used in a wide range of industries and products. The market forms of timber can vary greatly, from raw logs and sawn lumber to processed wood products and by-products. The ten different market forms of timber discussed in this article showcase the diverse uses and applications of this natural resource. It is important for businesses and consumers to understand the market forms of timber and their respective advantages and disadvantages in order to make informed decisions. As the demand for sustainable and eco-friendly materials continues to rise, it is crucial to carefully manage and utilize timber resources to ensure their availability for future generations. By understanding the various market forms of timber, we can promote responsible and sustainable practices that will benefit both the environment
