What are steel house frames?
Steel framing uses vertical columns and horizontal beams to create a building’s structural framework. For houses, light-gauge steel—thin sheets ranging from 1 to 3 millimetres thick—get bolted or welded together to form the interior frame. The steel used often has a galvanised or corrosion-resistant coating for increased durability when exposed to weather elements. Steel house frames have revolutionised the construction industry, offering a robust and versatile alternative to traditional wood or timber frames. Unlike their wooden counterparts, steel frames remain hidden behind cladding, brickwork, or renderings, creating a harmonious blend of strength and subtlety.
Why use steel frames for homes?
Steel house frames have emerged as a revolutionary and life-changing alternative to conventional wood framing. These lightweight yet robust frameworks have garnered worldwide recognition for their amazing impact on the home-building industry. As an experienced steel house frame builder in the field, I’ve witnessed firsthand the remarkable advantages steel frames bring, and I’m very happy to share them with you!
Durability Like No Other
When you’re talking about durability, steel reigns supreme over its wood-frame counterpart. From what I’ve seen in my years of working in the trade, steel’s resistance to warping and expansion outshines wood’s durability. Because Australia is home to crazy weather and climates, steel house frames can withstand natural forces like earthquakes, storms, and hurricanes without cracking or bending. Plus, you’ll be happy to know that steel can last over 150 years, which gives it a winning edge when choosing house framing materials. At Tag Steel House Frames, we ensure your steel frame house complies with Australia’s National Construction Code.
Timeless Power of Steel
Steel, a material renowned for its exceptional strength, has long been a cornerstone of the construction industry. Its ability to withstand immense loads and harsh conditions makes it an ideal choice for building structures that can endure the test of time. I remember one project I worked on years and years ago, which involved the renovation of an old warehouse into a modern apartment complex. The original structure, dating back to the early 20th century, was horrible and unmaintained, with its wooden frame showing signs of irreversible deterioration. We made the decision to replace the existing wooden frame with steel, which would reinforce the structure and extend the building’s lifespan. The transformation was incredible! With its sleek lines and unwavering strength, the new steel frame breathed new life into the old warehouse. The once dilapidated structure was now ready to withstand the rigours of time and provide safe, comfortable living spaces for generations to come.
Resisting Weather Like a Boss
Steel framing systems offer inherent properties that make them well-suited for a wide range of environmental conditions. Unlike other building materials, such as wood, steel exhibits consistent strength across a broad spectrum of temperatures, humidity levels, and precipitation exposure. Properly treated and maintained steel frames resist issues like warping, rotting, cracking, or infestation over their long lifespan. These durable qualities have made steel an increasingly popular choice for architects and engineers seeking to design resilient structures you can enjoy for years to come.
Value for Money
Steel-framed structures often prove to be more cost-effective than their wood counterparts. This is primarily attributed to steel’s inherent strength and durability, which allows for the use of smaller and lighter components compared to wood. Additionally, the precision of prefabricated steel components reduces construction time and labour costs, further contributing to decreasing your overall expenses and allowing you to save thousands of dollars in the long run.
Swift Assembly: Efficiency at its Peak
We love building materials that are highly effective and efficient at the same time! Steel frames and trusses are easier to assemble than wood. Prefabricated steel components arrive at the construction site ready for installation, eliminating the need for extensive and time-consuming on-site fabrication. Having a streamlined process and system such as this can reduce building time, allowing projects to be completed earlier without sacrificing quality or structural integrity.
Design Flexibility and Compatibility
Steel’s versatility extends to its ability to seamlessly integrate with other building materials, such as concrete, wood, and glass. This design flexibility and its ability to be moulded and shaped into the desired shape and size allow architects and engineers to create unique, stylish, and functional structures you will love. One project we had years ago tasked us to build two different structures: an art gallery and a historical museum. The contemporary art gallery required us to imbibe a modern and minimalistic look, while the latter required a more conventional design approach. Although their designs and vibe differed, we completed the project using our durable steel wall frames, trusses, etc. The gallery used exposed steel beams for an industrial chic look, while the museum had steel frames concealed behind concrete walls.
How does climate affect the choice of building materials?
The choice of framing materials for house construction is intricately tied to regional climate variations. Through my years building steel frames for homes in Queensland, I’ve learned to navigate the complex interplay between climate and optimal structural materials. Seasonal temperature changes, precipitation patterns, wind profiles, and humidity levels all shape how we choose building materials, construction timelines, and a building’s resilience to the climate.
- Rainfall: Historically wet regions may require updated rainwater runoff calculations. To withstand heavy rains, your homes should be built with weather-resistant, anti-corrosive, highly durable materials like zinc, steel, and Colorbond.
- Temperature: The primary concern is heat gain and thermal insulation in hot and arid climates. Materials like wood or concrete, which retain heat, may not be ideal. Steel frames, with their low thermal conductivity, can help regulate indoor temperatures and reduce energy consumption for cooling.
- Humidity and Moisture: In regions with frequent rainfall, moisture resistance is essential. If not properly treated, wood can be susceptible to rot and decay. With their inherent corrosion resistance, steel frames can better withstand moisture exposure
- Strong Winds: Wind, a silent adversary, holds immense power in its destructive capabilities. My firsthand encounters emphasise the importance of considering average wind speeds and prevailing directions during design. In regions prone to strong winds, such as coastal areas or mountainous regions, the framing material must be able to withstand high wind loads. Steel is a strong and lightweight material that can effectively resist wind forces. On the other hand, wood house frames may require additional bracing to ensure their stability in windy conditions.
How do wood and steel frames for homes adapt to changing climates?
| Climate Factor | Wood Frame | Steel Frame |
|---|---|---|
| Temperature Extremes | Wood can expand and contract with temperature changes, leading to warping and cracking in extreme climates. | Steel is more dimensionally stable and can better tolerate temperature swings, making it a more suitable choice for regions with hot summers and cold winters. |
| Precipitation | Wood is susceptible to rotting and decay when exposed to water, making it less suitable for areas with high precipitation. | Steel is non-combustible and will not rot, even when exposed to moisture. Additionally, steel frames can be treated with corrosion-resistant coatings to further protect them from moisture damage. |
| Wind Loads | Wood frames may require additional bracing to ensure their stability in windy conditions, especially in coastal areas or mountainous regions. | Steel is a strong and lightweight material that can effectively resist wind forces, making it a better choice for windy regions. |

Steel House Frames FAQ
The cost of steel house frames in Australia varies depending on the frame’s size, design complexity, steel grade, and project location. Industry estimates approximate an average all-inclusive installation price between $1,300 – $2,000 per square metre. This price can go higher and lower! Steel house frames also cost more than their timber counterparts, but this slight difference in price reflects in their durability.
Steel house frames are a durable and long-lasting solution for construction. Galvanisation provides significant corrosion resistance, but there are certain factors that can increase the risk of rust, such as scratches, abrasions, coastal environments, and chemical exposure. To counteract corrosion, there are several ways to protect the steel from rust, such as powder coating, hot-dip galvanising, and regular maintenance. By following these simple guidelines, you can keep your steel house frames in pristine condition, safeguarding your investment for years to come.
Steel house frames are a popular choice for home and commercial construction due to their strength, durability, and ease of assembly. However, one common concern is the potential for rust and corrosion. While steel is naturally resistant to corrosion, it can be susceptible to rust if the protective layer is damaged. Steel house frames are galvanised, meaning they are coated with a layer of zinc, which protects the steel from corroding.
