Advantages and the disadvantages of Light gauge steel construction

Light gauge steel construction is a modern construction technique that uses lightweight steel framing for buildings. This method has gained popularity in recent years, thanks to its numerous advantages. However, like any construction technique, light gauge steel construction has its share of advantages and disadvantages. In this article, we will discuss the benefits and drawbacks of light gauge steel construction in detail, with a particular focus on its quality and cost advantages, especially when combined with lightweight concrete or aerated concrete.

Advantages of light gauge steel construction

Quality — Light gauge steel construction is known for its high-quality finish. The use of lightweight steel framing enables the production of highly accurate and precise building components. This ensures that the final product meets the exact specifications and delivers excellent structural integrity. Additionally, light gauge steel construction is highly durable and can withstand harsh environmental factors, making it an ideal option for a wide range of building applications.

Cost — The cost of light gauge steel construction is another significant advantage. The use of lightweight steel framing reduces the need for expensive structural support, such as concrete and steel beams. This, in turn, reduces the overall cost of construction, making it a cost-effective option for building projects. Furthermore, the lightweight nature of the materials used in light gauge steel construction makes it easy to transport and handle, further reducing construction costs.

Speed — Light gauge steel construction is also known for its speed of construction. The lightweight steel framing used in this method can be easily and quickly assembled, reducing the overall construction time. This is especially beneficial for commercial building projects, where time is of the essence.

Disadvantages of light gauge steel construction

Sound insulation — One of the most significant disadvantages of light gauge steel construction is its poor sound insulation. The thin walls of the lightweight steel framing do not provide adequate soundproofing, making it challenging to create an acoustically sound building. However, this can be addressed by adding additional insulation layers or soundproofing materials during the construction process.

Fire resistance — Lightweight steel framing used in light gauge steel construction is also not as fire-resistant as traditional building materials. This is because the steel framing can weaken and lose its structural integrity when exposed to high temperatures. However, this can be addressed by adding additional fireproofing materials during the construction process.

Light gauge steel framing: The cost of light gauge steel framing for a building project can range from $2 to $10 per square foot, depending on the size and complexity of the project.

Lightweight concrete or aerated concrete: The cost of lightweight concrete or aerated concrete used in light gauge steel construction can vary depending on the type and amount used. For example, the cost of lightweight concrete can range from $70 to $120 per cubic yard, while the cost of aerated concrete can range from $70 to $90 per cubic yard.

Labor: The cost of labor for light gauge steel construction can vary depending on the size and complexity of the project. However, the lightweight nature of the materials used in this method can significantly reduce the need for manual labor, resulting in lower labor costs overall.

Conclusion

In conclusion, light gauge steel construction is a promising option for the construction industry, thanks to its numerous quality and cost advantages. When combined with lightweight concrete or aerated concrete, light gauge steel construction can provide even more benefits, such as enhanced durability and sound insulation. However, this method does have its share of disadvantages, such as poor sound insulation and fire resistance. Despite these shortcomings, the cost-effectiveness, speed of construction, and durability of light gauge steel construction make it an attractive option for building projects of various sizes and complexities.

The Pros and Cons of Lightweight Steel Framing

Things to consider before choosing lightweight steel frames

In every building construction project, framing is a process that should be taken seriously. For many years, builders have widely used steel framing for reasons that are hard to ignore. Yet, despite its reliability, some homeowners prefer to use wood instead of steel.

However, in order to use the best materials and products, consider the pros and cons using steel frames. Just like any other building strategies, lightweight steel framing has its pros and cons that you should consider when building but it does save a lot of time and labour if appropriately used.

The pros of using lightweight steel framing

There are many advantages of using steel in a building project that can’t be ignored and the positive points can ease your worries throughout your construction process.

1. Steel frames are lighter

When framing, the top choices for most construction companies are steel, concrete, and wood, depending on the type of construction being built. Steel frames are lighter than wood and concrete and are more durable. Despite it being light, it still serves its purpose like any other framing alternatives.

2. Steel frames are fire resistant

We all know that Australia is prone to bush fires, so steel framing is a good solution for your building. Steel is not flammable, and some manufacturers use a special steel coating for the frames to outlast extreme temperature. Steel frames become an essential advantage for reducing building damage in the event of a fire.

3. Steel frames are customisable and waste-free

Lightweight steel frames can be easily modified to fit a building structure, plus there are different sizes of steel available to fit any construction. Steel is easy to adjust, to fabricate the correct size and weight to bear the build load.

Steel is also an efficient material that is 100% recyclable and resistant to corrosion, to minimise any worry about frame deterioration, unlike wood, for example.

4. Steel doesn’t attract pests and insects

This is one of the deciding factors – with steel frames, building owners have one less thing to worry. Termites won’t be able to damage the property in the long run.

5. You don’t need to worry about water and moisture too!

Most of the time, structural steel is built with other components to withstand extreme weather conditions, like carbon. Some steel frame manufacturers add extra components such as hot zinc or excess powder for rust resistance to overcome heavy water exposure. So, weatherproof frames are a good investment.

The cons of lightweight steel framing

1. Price

If your project is on a tight budget, using steel frames might be problematic. This type of frame doesn’t come cheap, unlike wood and concrete alternatives. The key is to consider additional expenses such as the cost of specialised materials for upgrade requests. Also, self-tapping screws for fastening to your electric boxes and outlets are one thing to keep in mind with steel framing, and they can double up your labour costs.

2. On-site adjustments can be tricky

Wood frames can be adjusted on-site should you accidentally missed the correct sizing. However, this case is not the same with steel frames. Since these lightweight steel frames are manufactured with specialised materials, they cannot simply be cut to fit if a measuring error occurs.

3. Rust and Strength

Some steel frames may not include the extra rust preventing components. Once your frame begins to rust, it will become an issue that cannot be ignored because rust can create structural hazards.

Even though steel has its different advantages, it cannot function as heavy support to cabinetry and other heavy hanging structures. Drywall, sheathing, insulation, and other supplementary woods are required to build to support.

4. Steel frames have greater heat conductivity

Steel may be fire-resistant, but it also tends to attract extreme heat, due to its thermal conductivity, and home interiors can be affected during the hot summer. Fortunately, you can address this problem with centralised air-conditioning.

5. Steel framing needs professional steel fabrication and installer support

Steel framing is not to be done as a DIY project, a professional tradie should carry out the relevant work, if it is the right material. Installation of steel framing can be tricky too, with specific screw sets being required, so hiring steel fabrication and installers is practical and wise.
