In timber residential construction, as the name suggests, timber elements are the primary structural components used in the build. However, if you’ve ever walked past a timber residential construction site or perhaps visited one, you might have noticed steel elements such as steel beams and columns integrated into the structure (see the image below).
So, why is that?
Before we dive into the details, take a moment to think about it.
Why would structural engineers opt to include steel elements in what is essentially a timber-framed construction?

Got Your Guess? Let's Go Through It.
When you compare the mechanical properties of timber and steel, you'll quickly realise that steel is significantly stronger. For an equivalent size, a steel element can carry a much higher load compared to timber. To achieve the same structural capacity using timber, you'd need a considerably larger section, which could pose architectural challenges.
Imagine trying to fit large timber beams and columns within the walls, roof, or floor spaces—this is often impractical in residential designs. When space is at a premium, and timber elements won’t meet the design criteria, structural engineers turn to steel. That's why you often see steel beams and columns in timber residential builds; they provide the necessary strength without consuming much space.
Working as a structural engineer in the residential construction field, understanding why and when to use steel alongside timber is essential. But that's not all—you also need to be familiar with the typical column sections and sizes used in these projects. Not sure about the common sections and sizes? Well, that's a problem.
To be truly job-ready, you must bridge these gaps in your current skills and knowledge and what the industry requires you to have. Structural engineering isn't just about theory; it’s about knowing the right applications and being confident in your decisions.
So, back to the question raised at the start of this blog "Why Steel Beams and Columns Are Used in Timber Residential Construction?", did you have the answer to a standard question as such at your fingertips?
If not, it might be the right moment to start building that essential skillset and knowledge through targeted structural engineering courses.
