Building a residential structure in Australia using steel beams and columns can effectively ensure its structural integrity and durability. Structural steel is a popular choice for residential construction due to its strength, versatility, and resistance to fire and pests. Let’s explore the benefits and costs of using steel beams in residential construction and how structural steel is used to build homes across Australia.
Structural Steel & Residential Construction
As Australia’s leading steel supplier to the domestic housing market, it’s no secret that structural steel plays a massive role in building homes, buildings and all sorts of infrastructure in Australia. Using steel beams for residential construction offers several advantages over other materials:
- Stronger: steel has the highest strength-to-weight ratio of any current building material
- Stiffer: steel does not twist, warp, shrink or buckle
- Fire resistant: steel can reduce the risk of fire.
- Sustainable: steel is 100% recyclable.
It’s so good; it gives timber structures a run for their money. And thanks to computer technology, cutting and fabricating steel for construction is more cost-effective and efficient.
The Australian Steel Sector
The Australian Steel Institute (ASI) offers excellent insight into the nation’s steel sector, revealing the steel value chain's structure, capabilities and capacities. Approximately 1.5 million tonnes of steel are used in residential construction in Australia each year. Residential structural steel accounts for roughly 20% of the total steel used in the construction industry in the country.
The ASI notes that steel is popular for residential construction due to its strength, durability, and versatility. Steel beams and columns are commonly used in residential building construction to support walls, floors, and roofs. They can also be used to create large open spaces and to support heavy loads, such as in the case of multi-storey buildings.
Additionally, steel is often used in residential construction for its fire-resistant properties. It can withstand high temperatures without weakening or collapsing, which can help to prevent the spread of fires and protect the occupants of the building.
Overall, the use of steel in residential construction is a growing trend in Australia. The ASI expects this trend to continue as more builders and architects recognise the benefits of using structural steel in their projects.
Cost of Using Structural Steel in Residential Construction
While steel is a durable and versatile building material, steel beams for residential construction cost more than traditional materials such as wood or concrete. But wait, didn’t we just say structural steel is more cost effective and efficient? Well, the cost of using steel beams and columns in residential construction will depend on several factors, including the size and complexity of the project, the type of steel used, and the current market price.
However, it's essential to consider the long-term benefits of using steel in your building. Because steel is more durable and requires less maintenance than other materials, it can save you money in the long run.
Beams and Channels vs Columns and Posts
While steel beams, channels, columns and posts are commonly used in construction projects, these structural steel products have some critical differences.
Steel Beams and Channels
Steel beams and channels are typically used to provide horizontal support in a building's framework. Steel beams for residential construction are designed to carry loads across long spans and are commonly used in constructing walls, roofs, and floors. Steel beams are often used to support large openings, such as windows and doors, and can be used as columns in some applications. On the other hand, channels are mainly used for framing and can be used to support walls or as a track for sliding doors or other fixtures.
Steel Columns and Posts
Steel columns and posts are vertical structural members used to support the weight of a building's framework. Steel columns in residential construction are typically used in areas with large vertical loads or a need for additional support. Steel columns and posts can support the weight of the roof or the upper floors or reinforce walls. They are often used in multi-story buildings where the structure's weight requires additional support.
Steel beams and channels provide horizontal support in a building's framework, while steel columns and posts provide vertical support. Structural steel products are essential in construction projects and are chosen based on the project's specific needs.
Structural steel products are dependable and will provide structural strength and integrity for a lifetime. Furthermore, because our steel is hot dip galvanised, the risk of corrosion is eliminated.
Types of Steel Used For Residential Construction
Several types of steel beams are commonly used in residential construction in Australia. Here's a closer look at some of the most popular options:
W-beams are also known as wide flange beams and have a wide profile with a vertical web and two horizontal flanges. These beams are often used in residential construction to support large openings, such as doors, windows, and load-bearing walls and roofs.
H-beams are similar to W-beams but with a thicker vertical web and thinner horizontal flanges. They are commonly used in residential construction for load-bearing walls and roofs and for columns and beams in multi-story buildings.
I-beams have a narrow, vertical web and two horizontal flanges of equal size. They are often used in residential construction for load-bearing walls, roofs, columns, and beams in multi-story buildings.
T-section beams have a T-shaped profile with a vertical stem and a horizontal flange at the top. They are commonly used in residential construction for lintels, providing structural support for load-bearing wall openings.
L-section beams have an L-shaped profile with a vertical stem and a horizontal flange at the top. They are often used for multi-story buildings' lintels, columns, and beams in residential construction.
Channel beams have a C-shaped profile with a vertical web and two horizontal flanges. They are commonly used in residential construction for framing walls, as well as for lintels and other structural supports.
Steel beams are generally valued for their strength, durability, and ability to support heavy loads. Using different types of steel beams in combination with other building materials, residential construction projects can be designed and built to withstand the specific demands of the environment and climate in Australia.
How to Incorporate Steel Beams and Columns in Residential Construction
Hire a Professional Engineer or Architect
Collaborating with a professional engineer or architect with steel construction experience is essential when incorporating steel beams and columns in your residential construction project. They can help you design a structure that meets your needs and is structurally sound.
Determine the Optimal Steel Beam and Column Size
The size of your steel beams and columns will depend on the size and design of your building. Collaborating with a professional engineer or architect is crucial to determine the optimal size for your steel elements.
Consider the Connections
The connections between the steel beams and columns are critical for ensuring the structural integrity of your building. Several connections are available, including bolted, welded, and riveted connections.
