Frequently Asked Questions
Answers to what builders and homeowners most often ask us about steel framing.
What are the benefits of using structural steel in construction?
Structural steel provides excellent strength and durability, making it ideal for large and complex building projects. It offers design flexibility, resistance to pests and rot, and a longer lifespan compared to traditional materials like wood. Steel is also recyclable, making it an environmentally friendly choice.
What types of projects are steel roof trusses suitable for?
Steel roof trusses are suitable for residential, commercial and industrial projects. They are particularly beneficial for buildings that require large, open spaces without internal support, such as warehouses, factories and sports facilities. Steel trusses provide enhanced durability and load-bearing capacity compared to timber.
What are the advantages of steel floor joists over timber?
Steel floor joists are stronger and more durable than timber, providing a longer-lasting solution for flooring systems. They resist warping, termites and moisture, making them ideal for areas with high humidity or termite risk. Steel joists also allow for longer spans, which can mean fewer load-bearing walls and more open-plan designs.
Are frames made of steel more expensive than traditional timber frames?
While the initial cost of steel wall frames may be higher than timber, the long-term benefits often outweigh the price difference. Steel frames require less maintenance, are resistant to termites and fire, and have a longer lifespan — making them more cost-effective over time. They also reduce construction time thanks to precision and pre-fabrication.
How are Global Steel Frames’ products designed for earthquake and wind resistance?
Our structural steel, roof trusses and wall frames are engineered to withstand high loads and stress, making them ideal for areas prone to earthquakes and strong winds. Steel’s inherent strength and flexibility allow structures to better absorb and distribute forces during seismic activity or storms, reducing the risk of damage.
Can steel frames be used in residential home construction?
Yes — steel frames are popular in residential home construction. They provide a strong, durable and environmentally friendly alternative to traditional timber frames. Steel-framed homes are fire-resistant, termite-proof and offer greater design flexibility, especially for modern architectural styles.
Do steel frames offer better insulation than timber?
Steel frames themselves don’t offer insulation properties, but they work in conjunction with high-quality insulation materials to create energy-efficient buildings. Properly installed insulation around steel frames can minimise heat transfer and help maintain indoor temperatures, offering better insulation performance than timber-framed structures.
What is the lifespan of Global Steel Frames’ products?
Our structural steel, roof trusses, floor joists and wall frames have a long lifespan, exceeding 50 years. Steel’s resistance to corrosion, termites and other damaging factors contributes to its durability and long-term reliability in construction.
Are steel wall frames faster to install than timber?
Yes — steel wall frames are faster to install than timber because they’re prefabricated to precise measurements in our factory. This precision reduces on-site labour, speeds up construction time and minimises waste. The lightweight nature of steel also simplifies handling and installation.
How environmentally friendly are steel building materials?
Steel is one of the most environmentally friendly building materials available. It’s 100% recyclable, and steel construction generates less waste compared to other materials. Steel frames also often lead to more energy-efficient buildings due to their precision and compatibility with modern insulation systems, reducing the overall carbon footprint of a project.
