BridgeFab fabricates and erects structural steel works for clients in and around Brisbane

Structural steel is the heavy steel used as the load bearing member of a structure. This category of steel is used for the construction of transmission line towers, manufacturing sheds, and buildings.

BridgeFab specialises in medium sized structural steel projects ranging from 5T to 300T

Structural steel has a diverse range of applications. It offers a unique combination of guaranteed strength and flexibility of design. Almost any shape can be designed and fabricated because of steel’s capacity or bonding through the welding process. No matter the job, BridgeFab can take preliminary designs from a client, architect or engineer and work up detailed drawings that can then be fabricated into a viable project.

Two examples of this is the refurbishment of Ipswich hospital and the very demanding work required to fabricate and install UQ’s Global Change Institute.

BridgeFab has the demonstrated capacity to create custom one-offs that require attention to detail. This capacity can then be used in any project irrespective of complexity: school halls, portal sheds or industrial premises – indeed anything that calls for steel.

Technology and software to enhance fabrication and erection time

BridgeFab uses a combination of 3D scanning and drafting technology to plan your entire project before we touch a piece of steel. By accurately mapping out your project on your existing site we can provide you with a digitised copy of what the project will look like at the completion of the job without having fabricated any steel. The advantages of this is it allows you to assess the project and change anything you do not like before work commences. From BridgeFab’s perspective, the digitised copy enables our team to see exactly how each steel piece needs to be fabricated and where it is located in the overall design. This technology minimises mistakes and makes installation of the steelwork much more efficient and seamless.

Steel is essentially an element of iron that has been processed to control the amount of carbon in the material. While iron melts at around 1510 degrees Celsius, steel typically melts at about 1370 degrees Celsius. The exact melting point of steel, however, will depend on the specific type of steel being referred to. Most steel is composed of a number of other metals, each of which has an effect on its strength, resistance to corrosion and the ease with which it can be fabricated. These metals will also affect its melting point.

Steel fabrication refers to the formation of metal structures through the processes of cutting, bending and assembling structural steel. During the cutting process, steel is cut in one of three methods: shearing, chiselling or sawing; torching; and numerical control cutters. The bending process is carried out by either hammering or press brakes. With modern technology and software, this process can be done seamlessly. The assembling stage can be done by means of a number of methods, including welding, riveting and threaded fasteners.

The cost of our steel fabrication services will depend on the size of your particular project. If you would like to find out exactly what you can expect in terms of costs, we recommend that you request a quote from us. To do so, we ask that you simply complete our online form and our team will get back to you within two working days. The more details you can give us in terms of your project, site, location and plans, the better we can do at giving you an accurate quote. Alternatively, you are welcome to set up a meeting with us to discuss your project.

Structural steel is made from a combination of iron and carbon, as well as some other components like manganese, which improve its strength and durability. In fact, manganese is one of the most commonly added ingredients to structural steel (after iron and carbon) because it helps to bind the elements of the material to avoid cracking when it is being processed. Phosphorus is also sometimes added to structural steel as it helps to improve the strength of the material. Other possible additives include silicon, tungsten, vanadium, and chromium.


A PFC steel beam, also known as a steel channel, is used in a number of industries, including residential and commercial construction. PFC stands for Parallel Flange Channel, and these types of beams are made from very versatile steel that can be used as both horizontal and vertical supports. PFC steel beams can be also be used in the construction of columns, as support beams above doors, as well as supporting beams in floors. These steel beams are available in a wide range of widths and depths, depending on the intended use.

The first step in making structural steel is to crush and sort raw iron. Through a series of refining processes, the best grades of iron are gathered. Ore is then heated in order to remove any impurities. During the heating process, the pure iron sinks and the molten iron is drawn off and heated further. Other components are then added to enhance the strength and machinability of the material. The main ingredients in structural steel are iron and carbon, while manganese is also often added. Generally, the more carbon there is in the mixture, the greater the strength of the final steel.
