Steel Framing – What is it?

Steel framing uses steel columns and beams to create the skeleton of a building. It’s commonly used in homes, offices, and warehouses due to its strength, durability, and resistance to environmental factors.

When we decided to build our home, I was keen on using metal wall frames. Our area is known for its termite issues and bushfire risks, so I needed a reliable and safe option. I remember the day we started erecting the steel frames. It was impressive how quickly everything came together. The steel components, precision-engineered, fit perfectly, like a giant, life-sized puzzle. This not only sped up the building process but also ensured a straight and stable frame without the warping issues often seen with timber.

Living in a steel-framed home has been reassuring. We don’t worry about termites, and the fire-resistant properties of steel provide peace of mind during the hot, dry months. Overall, using steel framing has proven to be a smart choice, offering safety, durability, and a streamlined construction process.

Are steel frames prone to warping?

One concern I sometimes hear from homeowners considering steel framing is whether the metal studs and beams might eventually warp, twist, or bend out of shape over time due to environmental conditions. The simple answer is no—steel framing is extremely resistant to warping thanks to the inherent properties of the material itself. 

FactorSteel Frames
Modulus of ElasticityHigh, ensuring resistance to deformation under stress.
Thermal ExpansionLow, resulting in minimal movement or distortion with temperature changes.
Environmental ResistanceUnaffected by humidity, ensuring stability in various conditions.
Personal ExperienceProven stability in diverse projects, including humid conditions.

Steel has an extremely high modulus of elasticity, which essentially means it resists being deformed under load or stress. It also has a very low coefficient of thermal expansion compared to materials like timber. This makes steel dimensionally stable and not prone to warping, bending, or twisting from changes in temperature and humidity.

In my years of working with steel frames, I’ve never encountered a case of steel warping due to environmental conditions. One particular project during Australia’s humid summer demonstrated this perfectly. While other materials showed signs of movement and distortion, the steel frames remained unaffected, providing a solid and reliable structure for the home.

How many years do steel frames last?

From my experience in the steel frame manufacturing industry, I can confidently say that steel frames are incredibly durable and long-lasting. When we built our family home using steel framing, I was reassured by the material’s impressive lifespan. Steel frames can easily last 50 years or more with minimal maintenance, making them an excellent investment for any homeowner.

I recall a project where we revisited a commercial building we constructed with steel frames over two decades ago. Despite the passage of time, the frames were in pristine condition, showing no signs of warping, twisting, or deterioration. This longevity is due to steel’s resistance to common issues like termites, rot, and fire.

Comparing steel frames to other materials, such as timber, the differences are stark. Timber frames, while initially cheaper, are susceptible to pests and environmental damage, often requiring frequent repairs or replacements. In contrast, steel frames maintain their integrity and strength over time, providing consistent support and stability.

Are steel frame houses stronger?

As someone who has worked in the steel frame manufacturing industry for over a decade, I can confidently say that steel frame houses are indeed stronger than their traditional timber-framed counterparts. A particular incident that stands out is a project in Queensland’s northern suburbs. One of our clients chose a steel frame for their home, mainly due to its strength and durability. This decision proved wise when a severe storm hit the area. They had opted for a steel-framed home, and their decision paid off remarkably. During a severe storm that swept through the area, the steel-framed home of my client withstood the onslaught with minimal damage. At the same time, neighbouring houses with traditional timber frames suffered significant structural damage.

This real-life example highlights the inherent strength and durability of steel frames. Steel frames are engineered to withstand extreme conditions, including high winds, heavy snow, and even earthquakes. According to the Metal Building Manufacturers Association (MBMA), steel structures and pre-engineered metal buildings offer substantial benefits compared to traditional wooden buildings. Their research and testing have shown that steel is a superior building material in many ways. Unlike timber, which can warp, twist, or rot over time, steel maintains its integrity and strength. Moreover, steel frames offer superior fire resistance compared to timber frames, providing homeowners with an added layer of safety. In the event of a fire, steel frames can maintain their structural integrity for longer, allowing more time for evacuation and emergency response. This durability ensures that homes built with steel frames are not only stronger but also safer in adverse weather conditions.

Are steel frame homes fireproof?

From my personal experience in the steel frame manufacturing industry, I can confidently say that steel frame homes offer significant fire resistance, although they are not entirely fireproof. Steel’s non-combustible nature makes it an excellent choice for building in fire-prone areas. 

One project that drove home the fire resistance of steel framing was a home I helped construct a few years ago in the bushfire-prone South Eastern Queensland. The clients had retired there after careers in the city, drawn by the natural beauty but also concerned about the potential wildfire risk to the area.

“We want to build a home that can withstand burning embers and radiant heat as much as possible,” John told me when we first met on-site. “The peace of mind is really important to us.”

That’s when I explained how steel framing is non-combustible and doesn’t add fuel to a fire like wood framing.

Studies have consistently shown that steel frames perform exceptionally well in fire tests. According to a study by the National Research Council of Canada, steel structures maintain their load-bearing capacity much longer than traditional materials in fire conditions. This characteristic significantly enhances the safety and durability of steel-framed buildings in the event of a fire.

Dispelling The Most Popular Steel Framing Myths

Myths about steel framing, Tag Steel House Frames

In my years of supplying steel frames for residential projects across Queensland, I’ve encountered plenty of misconceptions about this modern building method. Here are the facts behind some of the most common steel framing myths: 

Myth 1: Steel Frames Are Prone to Rust

One of the most persistent myths is that steel frames rust easily, especially in coastal areas. From my personal experience, this couldn’t be further from the truth. For instance, we completed a coastal project in Queensland where we used galvanised steel frames. Despite years of exposure to salty air, the frames showed no signs of corrosion. The galvanising process provides a robust protective layer, making steel frames highly resistant to rust. According to a study by the National Association of Steel-Framed Housing (NASH), galvanised steel frames have a service life of over 60 years, even in coastal environments, thanks to their protective zinc coating.

Myth 2: Steel Frames Are Not Energy-Efficient

Modern steel framing systems are engineered with energy efficiency as a key consideration. While steel itself is not an insulating material, cavities within the framing can be filled with various insulation products, like batts, rigid boards, or spray foam.

Myth 3: Steel Frames Cause Electromagnetic Interference

Another myth I frequently encounter is the belief that steel frames are susceptible to electromagnetic interference, which could potentially disrupt electronic devices and appliances within the home. However, research conducted by the Steel Framing Alliance (SFA) has proven that steel frames do not cause any significant electromagnetic interference, and their impact is well within acceptable levels.

Myth 4: Steel Frames are Noisy and Lack Insulation

While it’s true that steel is a dense, rigid material that can transmit sound more readily than wood framing, this only becomes an issue if no insulation or sound-proofing measures are taken during construction. A well-insulated, properly built steel frame home shows little to no difference in exterior noise levels compared to timber framing. 

Working on various projects, I’ve witnessed firsthand the incredible durability, cost-effectiveness, and reliability of steel frames. For instance, seeing a coastal home with galvanised steel frames withstand the test of time without rusting, or observing the long-term cost savings for homeowners due to the low maintenance of steel structures has reinforced my belief in steel framing. For anyone considering using steel frames, understanding the facts through real-life examples can help make an informed and confident decision.

The Right Frame for Your Dream Home: Weighing the Options

When choosing between steel or timber framing, it’s crucial to consider the unique requirements of your project. From my experience across dozens of residential builds in Queensland, steel offers exceptional durability, strength, and precision that make it an increasingly popular option for modern homes.
