In the world of construction, the choice of materials depends on a number of factors. While some constructors will make use of wood, others will make use of metal or better still ceramic. Notwithstanding all the factors, there are massive advantages of steel trusses over wood.

Over the years, materials used in construction have gained s+everal forms of modifications to suit our modern-day life. Others also have a concept that old materials are best to use in this era.

From the concepts of Material Science, every material in the world is basically made of either metal, polymer or ceramic or perhaps a combination of any of them. Trusses are structural members made from straight pieces of metal or wood to form a series of triangles lying in a single plane.

Trusses have been in existence for centuries as a remedy to solve the rapid failures of structures due to their ability to withstand and support large loads. One worry that engineers faced in their construction works was the instability of the materials. They then designed a triangular-shaped structure called a truss to be used in place of the weak unstable materials. 

The major materials used in the construction of trusses are wood and metals. These materials have a great effect on the strength and life span of the building and thus metallic trusses are the best. Wood trusses are inferior to metallic trusses in all aspects as metallic trusses have proven to be more advantageous. The advantages of steel trusses over wood cannot be overlooked.

What Are The Advantages Of Using Trusses?

Trusses provide a great variety of functions and advantages. Some of the advantages include the following: 

  • Trusses are extremely strong.
  • Trusses have high stability.
  • They withstand extreme weather conditions.
  • Trusses are easy and quick to install
  • Trusses have a long lifespan.
  • Trusses create the best load distribution.
  • The flexibility of design is high in trusses.

What Are The Disadvantages Of Roof Trusses?

Roof trusses, whether made of steel or wood, have some shortfalls. The only major disadvantage of roof trusses is their inability to leave enough space for a usable attic. On the occasion where the roof designer tries to create his own space for the attic, it leads to a reduction in the lifespan of the roof trusses.

What Is The Purpose Of A Truss?

Trusses serve a very great purpose in the world of construction. Trusses play a very great role in the construction of roofs, bridges, towers and other materials. The purpose of a truss is to provide sufficient stability, strength, and proper distribution of loads in construction materials.

A truss is environmentally friendly, energy-efficient,  as well as provide support to materials and structures.

What Are The Uses Of Trusses?

As the main purposes of trusses have been spelt out, there are other important uses of trusses in construction. Amongst them are:

  • Trusses are used in other civil construction aspects such as the construction of a scaffold.
  • Some forms of cranes are built from trusses. Moreover, the cantilever beams of cranes are made of trusses.
  • Trusses are useful in the construction of power pylons or transmission towers.
  • Trusses are used in designing railway platforms.
  • Some sections of sports stadiums are made of trusses

What Makes A Truss Strong?

The basic structural unit of a truss is a triangle. Trusses are strong due to the triangular arrangement of the structural elements. The triangular nature of trusses makes them resist a much larger load in tension or compression. Moreover, the proper load distribution of trusses improves the strength of structures due to the uniform distribution of the load.

What Are The Advantages Of Wood Roof Trusses?

Although it is generally accepted that steel trusses are more advantageous than wood trusses/ Here is a list of some of the beneficial aspects of wood roof trusses:

  • The wood roof trusses are eco-friendly.
  • Wood Roof trusses are flexible.
  • They are durable and strong.
  • They are energy efficient.
  • Wood Roof Trusses are cost-effective.

Advantages Of Steel Trusses Over Wood

Although both steel and wood can be used in the construction of trusses, the overall performance of the steel trusses is better than that of the wood trusses. Steel is ahead of wood in the construction of trusses with respect to the weight, eco-friendliness, durability, fire-resistance, resistance to mould and mildew growth and design nature.

Advantages Of Steel Trusses Over Wood With Respect To Weight

In terms of weight in the advantages of steel trusses over wood, let us assume a square length of a building is to be roofed using either steel trusses or wood trusses. When steel trusses are used, their weight on the building is quite lighter than when a wood truss is used. 

Advantages Of Steel Trusses Over Wood With Respect To Fire-Resistance

The way and manner in which woods are destroyed by fire are higher as compared to steel. As a result of this, it will be advantageous to use steel trusses over wood trusses.

Advantages Of Steel Trusses Over Wood With Respect To Durability

One of the important deciding factors used in the selection of materials is the lifespan of the material. The strength, resistance to mould and mildew, are factors that prove that steel trusses provide more advantages than wood trusses. Steel trusses can last longer than wood trusses. Steel can withstand high-stress situations under scenarios of both tension and pressure.

Advantages Of Steel Trusses Over Wood With Respect To Ease In Transportation

It is easier to transport steel trusses than to transport wood trusses of the same size.

Advantages Of Steel Trusses Over Wood With Respect To Susceptibility To Mould and Mildew Growth

Wood is susceptible to mould and mildew growth and damage. Steel, on the other hand, is not susceptible to mould and mildew and thus cannot be damaged by the growth of mould and mildew. As a result, steel trusses are recommended.

How Do Trusses Work?

The wonderful load-bearing nature of wood trusses is still not fully understood by many. In terms of stability, a triangle provides it at maximum. When you impose a load at either side or joints of trusses, the load is uniformly transmitted through the other parts of the truss, thereby, supporting the load. 

Are Steel Trusses Cheaper Than Wood?

Generally, wood trusses are cost-effective as compared to steel trusses. Notwithstanding that, additional costs are accrued for chemical treatment of the wood to prevent insects and other organisms from destroying them. It is more convenient to transport steel trusses as compared to wood trusses. So in a broader sense, steel trusses are cheaper than wood trusses.

The advantages of steel trusses over wood trusses are very clear and need to be understood. Stability and strength are very vital in all construction works. Domod Roof provides quality and durable steel trusses that make construction better.
