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.

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.
