Why Structural Steel is Mostly Used in Construction

Structural Steel Construction

According to Wikipedia, structural steel is a category of steel used for making construction materials in a variety of shapes. Structural Steel stands out as the most used structural material in the construction industry along with concrete both in Australia and all other parts of the world. Ranging from the most popular buildings and famous skyscrapers to magnificent bridges that fly over the oceans and connect the islands, down to the most beautiful modern homes, structural steel is widely used in all of these structures regardless of the design they originate from. Structural steel is used more in the construction industry because it provides building professionals the liberty to bring their designs to life. Irrespective of the kind of construction project, you will most likely be using structural steel in one form or another to complete the project for a longer lifespan. Structural steel comes with amazing and distinct qualities from other construction materials making it undeniably the material of choice among construction professionals like the architects, engineers and many building contractors across Australia. Below are some of the most recognisable reasons structural steel is a preferred choice for construction.


Beyond doubt, structural steel is the strongest construction material here in Australia and all over the world. Even concrete structures need steel reinforcements to attain stability. Concrete has high compressive strength but poor tensile strength while structural steel has high strength both under the action of tension and compression forces. It has the highest strength-to-weight ratio than any other building material, making it more favoured for the building and construction of both large-scale and small-scale structures like long and high bridges like the Sydney Harbour Bridge and skyscrapers.

In Australia, national standards are followed in the production of structural steel. Structural steel plates like the XLERPLATE® steel produced is produced according to Australian Standards. With grades ranging from medium to high strength steel plate products with varying nominal yield strengths.


Another major reason structural steel is mostly used in so many construction projects is that of its durability. Durability is the ability of structural steel to withstand extreme forces – whether from natural or human sources – for a long time. Steel structures have proven over time their ability to withstand extreme weather conditions like heavy snow and tornadoes and severe natural disasters like earthquakes, hurricanes, and tsunamis. These natural forces may seem small but they have caused large-scale catastrophes in Australia in the past affecting the sturdiness of many structures. Structural steel is not an organic material like wood, so it doesn’t rot, split, crack, warp, twist, or break. Unlike structures built with timber, steel is resistant to rust or termites, bugs, fungi or mildew. Steel is also fire-resistant will not burn, and will not provide fuel when there is a fire outbreak.

Adaptability and Elasticity

Adaptability is the ability of structural steel to be hammered and adjusted to fit any required size that the owner wants while elasticity is the ability of steel to be distorted, cut, rolled or stretched into any shape and size without changing its other physical properties. Using steel has proved better than other materials because it does not warp, clink or splinter. Fabrication of structural steel is achievable because of steel’s adaptive and elastic properties.

In Australia, structural steel is not only used as structural members of a building but can also be used for aesthetics, storage tanks, and general fabrications. For instance, steel plates like XLERPLATE®, made from structural steel by BlueScope Plate Supplies, are used not just for structural stability but also for aesthetical purposes or even both at the same time. This ability to adjust and adapt to the required shape and size surely makes steel a preferred choice amongst designers and their clients.


These many qualities and benefits of structural steel contribute to steel being a very affordable option for construction projects. Structural steel is often made of partially recycled materials and it is built to last. Any project that involves steel will be more cost-effective over time than one that uses other metals, or wood because other materials involve a high maintenance cost.

It doesn’t matter if your proposed project is a residential, commercial, or industrial building, steel is a worthy investment. If you are looking at using such material for a construction project, make sure you consult with top suppliers in Australia to get structural steel at its best form.
