What Is Graded Timber And Why Is It Used?

What is the difference between unseasoned and graded lumber? It doesn't matter whether you purchase pre-cut wood, pre-finished timber or recycled wood. It is only the type of wood you purchase as well as the method by which it was taken. Unseasoned timber is generally sold as un-seasoned, softwood that is wet and often combined with non-seasoned softwood typically oak. It has a smooth, un-matured surface. Its measurement can range from 3mm to 5.5mm wide. It has a natural wavy edges and a rough sanded finishes.

However graded lumber undergoes various treatments to give it the highest durability and strength. In the beginning, the wood is divided into pieces, and sections are then placed in annealing ovens to improve the toughness and resist the wear and tear. In the process of annealing the grade is altered as the sections are put back together to form a new block. Graded timber, specifically ones made by the companies of Western Australia, New South Wales and Victoria are renowned for their strength in load bearing and stability. This is due to the fact that the load bearing blocks grade a constructed from Australian Kauri are mostly used for flooring, walls and roofs.

In addition to the advantages that were mentioned earlier, another advantage of unseasoned lumber as compared to graded lumber is its aesthetic and practical qualities. When you have unseasoned timbers the grain pattern is straight, even and smooth. It does not also show any obvious flaws or knots. The timber that is not seasoned has a straight grain. The graded timber, however, when exposed to water or treated by preservatives, tend to create a honeycomb pattern that appears uncut irregular, irregular and has large gaps and impurities inside the grain. If this defect is not eliminated, may compromise the structural integrity of the timbers.

Although the two types of timber are different in appearance they are both equally useful and practical. Graded timber has better structural strength and durability since it is stronger and more durable than timber that is not seasoned. It is also stronger when exposed to high temperatures and is more resistant to impacts due to the changing temperatures. Another benefit of graded lumber is that when it has been used for a long time it becomes less prone to shrinkage and swelling which is a typical occurrence with unseasoned carcass timber.

Additionally, the grade of the product will also determine the degree of structural flexibility that it has. In the absence of a proper treatment, carcasses can crack easily, especially around the pins that connect them. But, the quality of the carcass will determine how flexible it is i.e. how well it can adapt to changes in temperature or humidity.

The benefits of graded lumber over unseasoned timber are numerous. It helps to make shipping and storage more efficient. Wood products that are graded are generally lightweight and require only minimal physical effort and make storage, transportation and shipping much more efficient. Additionally, c24 boards are safe from fire and are not combustible. They can even be totally recycled after usage.

Graded lumber has distinct advantages that makes it a sought-after choice for construction. For one, since it's more durable than unseasoned lumber and requires less screws and nails. This makes it simpler to set up. Another advantage of using graded wood in construction is that it has more durability compared to dimensional wood and a corresponding increased the capacity to bear load (FLC) which in turn leads to higher strength for the structure.
