What is a steel truss frame?
A steel truss frame is a structural framework composed of interconnected steel components arranged in triangular units. These frames are predominantly used in building construction to support roofs or floors. The triangular configuration provides stability and strength, enabling the frame to bear various loads, including snow, wind, and maintenance activities.
Steel frames are particularly advantageous for roofing due to their excellent strength-to-weight ratio. They can support longer spans without the need for intermediate supports, offering greater flexibility in architectural design. This allows for expansive, open interior spaces and innovative design solutions. Furthermore, steel trusses can be customised to meet specific construction requirements, making them suitable for residential, commercial, and industrial applications.
What makes steel frames the best choice for roofing projects?
Steel truss frames offer a multitude of benefits that make them an ideal choice for roofing projects:
Strength and durability
Steel framing systems are renowned for their resilience and ability to withstand extreme weather conditions such as wind, rain, and snow. Unlike other materials, steel does not deteriorate over time, ensuring longevity and minimal maintenance. In fact, well-maintained steel structures can last for decades, providing a reliable solution for long-term projects.
Cost-effectiveness
Although the initial cost of steel may be higher than some other materials, the long-term savings are substantial. Steel trusses require less maintenance, reducing ongoing repair costs. Plus, by using steel framing, it’s possible to cut down the construction timeline by 5-6 weeks, amounting to savings of $5,000 per week—totalling $25,000 per project.
Design flexibility
Steel is suitable for a variety of architectural designs and structural configurations. Steel framing is adaptable to different building shapes and styles, ranging from traditional to contemporary architecture. The versatility of steel extends to interior spaces, allowing for open floor plans and large spans without the need for additional support columns.
Ease of installation
Steel trusses are manufactured to precise specifications, ensuring a perfect fit on-site, which reduces construction time and labour costs. Time-related savings from steel frames can amount to between 3% and 5% of the overall project value, reducing the building owner’s requirements for working capital and improving cash flow and return on investment.
Environmental sustainability
Steel trusses are highly recyclable and can be reused multiple times without losing their benefits, which makes them an environmentally friendly element in construction. Recycled steel maintains its strength, durability, shape, and quality and steel frames have a significantly lower impact on the climate when compared with other roofing materials.
Fire resistance
Steel’s high melting point of around 1,370°C makes it a non-combustible and highly fire-resistant building material. This property reduces the risk of fire-related damage, enhancing the safety of the building and its occupants. Steel frames become especially handy for construction projects in fire-prone areas as they provide a secure solution.
How do steel truss frames compare to other roofing options?
Wooden truss frames are a more traditional selection by home builders and owners when it comes to building houses, appreciated for their aesthetic look and flexibility in modification. They have a classic appearance that many homeowners and builders love. However, while steel frames are less traditional, they are becoming increasingly popular due to their numerous advantages.
Steel frame trusses outperform wooden truss frames significantly in strength, durability, and robustness. Wooden trusses can support up to 6,000 pounds of load, whereas steel trusses boast a significantly better strength-to-weight ratio, supporting up to 24,000 pounds. Steel truss frames can last for more than 50 years while wooden roofs have a shorter lifespan of around 20-30 years before they need replacement due to wear and tear from exposure.
In terms of cost-effectiveness, wooden truss frames are cheaper initially, but require more maintenance over time. They can easily get affected by rot, pests, and warping that demand constant repairs or replacements. Steel frames are stronger and last longer without needing as much care—reducing the total long-term expense while offering a more economical choice for homeowners and builders.
Steel frames vs. wooden truss frames
Steel frames vs. Concrete trusses
Concrete trusses are generally used in commercial and industrial buildings due to their exceptional strength and ability to resist fire, providing a level of safety. Their robust quality ensures they are highly durable. That said, steel trusses also provide excellent strength and resistance against fire, and are lighter and simpler to handle, which makes steel frames a versatile and efficient option for various construction projects.
When it comes to the ease of installation, concrete presents challenges due to its heavy weight, leading to higher transportation and handling costs. The lengthy installation process for concrete is more labour-intensive and time-consuming. In contrast, steel frames are much lighter, making them easier and quicker to install. This not only reduces overall building overheads but also shortens construction timelines, providing significant advantages in both residential and commercial projects.
Steel trusses also win in design flexibility, because concrete, being heavy and rigid, usually needs extra support structures. Steel frames allow for longer spans without needing columns for support, which opens up a more innovative and modern design approach.

FAQs
Can steel frames be integrated with renewable energy systems?
Yes, steel frames can support the installation of solar panels or green roofs, enhancing a building’s energy efficiency and sustainability. Their robust structure provides a stable platform for renewable energy applications.
How do steel frames enhance architectural aesthetics?
Steel frames offer architectural flexibility, allowing for unique designs and expansive, open spaces that are not easily achievable with traditional building materials. Their sleek profiles and ability to span large distances without obstructive columns enable striking architectural statements in modern buildings.
What role do steel frames play in disaster resilience?
Steel frames are resilient against extreme weather events such as hurricanes and tornadoes. Their ability to withstand high wind loads and minimise damage helps protect buildings and their occupants, contributing to community resilience and disaster preparedness.
