Grading is an important part of the timber selection process – for both our team and yours. It provides key information on the quality of specific batches of timber products and goes a long way to ensuring your project is paired with the right timber for the job. In short? It is a good idea to understand more about timber grades and how they impact your project.

In this guide, we will take a look at visual grading, exploring what it is and how different grades impact the aesthetics of your project. Let’s dive into it!

What is Timber Grading?

Visual grading is a process of inspecting timber, using visual cues to get a better idea of the natural features of the wood. This is not down to personal opinion – the professionals who carry out visual grading follow strict industry standards, making it easier for everyone to understand exactly the qualities of timber they are getting.

Graders look for characteristics such as:

  • Knot size and frequency
  • Grain direction and slope
  • Colour variation
  • Resin pockets and small defects

While this is geared towards aesthetics, visual grades can give us an idea of the timber’s structural integrity. A board with a lot of knots, for instance, will have more weak points and could bring less strength and durability to your project.

Types of Visual Grades

In the timber industry, there are typically three types of visual grades. These are:

  • Prime grade: This is the timber with the least visual defects.  Prime boards have minimal knots, even colouring and a smooth, refined appearance, giving them a uniform look. As fewer boards meet this standard, they tend to be more expensive but if you are on the hunt for a sleek timber, then this is what you will want.
  • Character grade: Character grade includes timber with a few knots, colour variations and a more uneven grain. These boards tend to have a bit more character while still looking fairly neat for a perfect middle ground between prime and rustic timber.
  • Utility grade (or rustic grade): If you are looking for a timber with a lot of personality, you will want utility/rustic grade. This contains much larger knots and a more varied grain which, though it can have poorer structural integrity, has a wonderfully rustic look.

How Grading Influences Aesthetics

When it comes to aesthetics, prime-grade timber tends to be favoured by contemporary architects and designers who love a clean, modern finish. Few knots and even colouring lend it well to detail-oriented design, and it is in high demand for projects such as cladding, where aesthetics take centre stage.

Character and rustic grades are better suited to a look which embraces charm and originality. Each board will be slightly unique, bringing a whole lot of variation to your overall style, which many find to be warm and welcoming when used in construction.

Whilst common species, such as Oak, are sold specifically in these visual grades, other species may not be so readily “labelled”. Speak to our team of experts to learn more about what to expect and where in these scales the species you are considering would sit.
