Steel frames and trusses have gained immense popularity in modern construction because of their durability, versatility, and sustainability. Despite the benefits associated with steel frames, however, several myths still exist.
Such myths discourage people from opting for steel frames for their construction projects even when it might be the best option for them. Let’s try to address some of the most common myths surrounding steel frames and put the record straight.
Myth 1: Steel Frames Rust
Reality: Among the most widespread myths surrounding steel frames is that they are prone to rusting, especially in moist or coastal environments. But that’s not true today since the modern steel frames receive a protective coating through galvanisation or specific paints.
These coatings ensure that steel remains strong and resistant to moisture, even in challenging conditions. Even more, maintenance of a regular basis can ensure prolonged life for steel frames for decades without rusting.
Myth 2: Steel Frames Are Not Energy-Efficient
Reality: Some people think that steel frames are poor insulators and, therefore, cannot be used in energy-efficient buildings. While steel is a good conductor of heat, the construction techniques used today mitigate this problem.
Thermal breaks and advanced insulation materials can be used to minimize heat transfer and eliminate the possibility of thermal bridging. Steel frames, when properly used, can lead to highly energy-efficient buildings with minimal indoor temperature fluctuations and lower energy consumption.
Myth 3: Steel Frames Are Too Expensive
Reality: While at first glance, a steel frame might appear to be more expensive than other traditional materials like timber, the cost benefit is only for the long run.
Steel frames are also strong, low-maintenance, and have a long lifespan compared to other materials. Steel is also less prone to pest and environmental damage and fire damage; thus, the repair and replacement costs are relatively cheaper. The lifecycle cost analysis often proves that steel frames are more cost-effective.
Myth 4: Steel frames are weak against fire
Reality: This myth is so far from the truth. Steel does not ignite, and neither does it add to the spread of flames. It is a fire-resistant material, in fact, that is widely used in building construction for such properties.
Comparing to that of timber, which would catch fire really fast, the strength in structure is seen in steel when its temperature attains much higher levels of heat. Combining some fireproofing measures that include cladding or application of intumescent paints, steel-framed construction offers great safety against building fires.
Myth #5: Steel Frames Rattle and are Noisy.
Reality: There are many opinions that steel-framed constructions are noisy and creaky. Again, in most cases, this might be a misnomer based on obsolete construction strategies.
Modern steel-framed buildings apply sophisticated engineering skills to reduce noise. For example, the design is integrated with soundproofing materials and insulation to reduce noise transfer between rooms and floors. Well-constructed steel-framed buildings are as silent as those built with other materials.
Myth 6: Steel Frames Are Difficult to Modify or Expand
Reality:: Some believe that steel-framed buildings are difficult to change or extend once they are built. The truth is that steel frames are highly flexible when it comes to design.
Their modular construction makes them easier to modify than other materials. Adding an extension, opening up larger windows, or making structural changes is easier with steel frames if a professional is working on it.
Myth 7: Steel Frames Are Not Applicable for Residential Buildings
Reality: Steel frames are so much associated with large-scale commercial or industrial buildings, but that’s changing in residential applications.
Steel frames are really suited for homes because they come strong and durable and accommodate many modern design features such as open-plan layouts and the installation of large windows. In addition, steel frames are quite light, thus easier to transport and assemble, which, therefore, saves construction time.
Myth 8: Attract Lightning
Reality: It is believed that steel-framed structures are more prone to lightning strikes. Fact: This is a misconception because of the conducting nature of steel.
Lightning does not target steel-framed structures more than any other type of building. Additionally, steel frames can safely conduct the energy from a lightning strike to the ground, reducing the risk of fire or structural damage. In fact, steel frames often enhance a building’s safety in lightning-prone areas.
Myth 9: Steel Frames Are Not Eco-Friendly
Reality: It’s an untrue notion that the steel frame is harmful to the environment, for it involves the usage of so much energy in production. Yet, steel happens to be one of the most eco-friendly construction materials there is.
Steel is 100% recyclable and can be reused multiple times without losing its structural properties. Buildings with steel frames often utilise recycled steel, which significantly reduces the environmental impact of construction. When combined with energy-efficient building designs, steel frames contribute to more sustainable construction practices.
Myth 10: Steel Frames Are Vulnerable to Earthquakes
Reality: On the contrary, steel frames are very resistant to seismic activities. Their strength and flexibility make them a perfect choice for earthquake-prone regions.
Steel can bend without breaking, which enables it to absorb and dissipate the energy produced by an earthquake. This flexibility decreases the chances of structural failure, which in turn provides a safer environment for occupants.
Myth 11: Steel Frames Are Too Cold for Living Spaces
Reality: Another misconception is that steel frames make homes cold and unwelcoming. While steel itself can feel cold to the touch, this does not translate to the overall comfort of a building.
Proper insulation and thermal barriers ensure that steel-framed buildings maintain comfortable indoor temperatures year-round. Additionally, steel frames can support energy-efficient HVAC systems, making them as warm and cosy as homes built with other materials.
Conclusion
Steel frames and trusses are one of the most versatile and reliable modern forms of construction, yet misconceptions sometimes cloud their value. Fears over rust and fire resistance to being too costly and damaging the environment seem to come out of some outdated information or a simple lack of knowledge.
Builders and owners will only be able to take full advantage of the potentials of steel frame construction and enjoy all its durability, energy efficiency, flexibility, and sustainability benefits if they accept realities in that regard. As a matter of fact, steel frames are practical and forward-looking choices for the future.
