Steel Fabricators Australia
What is steel fabrication?
The idea of fabricated steel may seem complicated when you first hear about it, but it’s actually very straightforward. It’s simply the process of making various types of steel metals into the shape of a final product or just a piece of one. Of course, you can’t trust just anyone with your steel fabrication. It’s important to use experienced technicians who know exactly how to handle the technical processes of cutting or burning, forming, machining and welding – which is where we come in.
What are the basic raw materials involved with metal fabrication?
Every steel fabricator in Australia needs to have a certain amount of raw materials on hand for most steel fabrication projects, these include:
- Formed and expanded metals
- Flat metal
- Sectional metal
- Welding wire
- Plate metal
Who needs steel fabrication services?
Any industry or business that requires the use of steel metal products needs the services of a steel fabricator in Australia. For residential and commercial construction businesses, as well as industries like mining, manufacturing and shipbuilding, fabricated steel in the form of things like bar joists, platforms, and universal beams and columns are an essential element of their successful operations.
What is the process of structural steel fabrication?
Transforming steel into a product or a range of shaped components is the essence of structural steel fabrication, but what’s the step-by-step process?
- Creation: Before anything can be made it has to be thought of first. This stage is all about figuring out exactly what specifications you need
- Blueprint: Once all the details are ironed out they’ll be imputed into a computer system that outputs the requirements
- Shop drawings: After the finalisation of the blueprint, the shop drawings are created to finish the process
History of portal frames
One of the most popular kinds of structural fabricated steel is steel portal frames, a type of structural frame most commonly used for building sheds in Australia. First developed during World War II, this technique is used in the creation of factories, aeroplane hangars, warehouses and other wide-span structures.
Advantages of portal frames
One of the greatest advantages of using a steel portal frame is that they’re inexpensive and are a cost-effective option in the creation of large and wide structures. They’re also simple and quick to build, can be used for multiple needs, and are relatively low maintenance.
Galvanised Steel FAQ:
Q: What is fabricated structural steel?
A: Structural steel fabrication is the bending, cutting and shaping of steel to make a product or a component of a product. Structural steel fabrication is used across construction, manufacturing, automotive, shipbuilding and other industries.
Q: What is a girder in a bridge?
A: A box girder is made of two concrete slabs that are connected by a web of vertical bridge stems. A Box girder bridge is a bridge in which the main support beams are constructed of girders shaped like a hollow box.
Q: What are girders used for?
A: Girders are primarily used to build bridges. There are several types of girders, the most common include box girders, plate girders and gantry girders.
Q: What is the difference between a beam and a girder?
A: The main difference between a beam and a girder is the size of the component. All girders are beams but not all beams are girders. If it is the chief horizontal support in a structure, it is a girder. However, if it is a smaller structural support, it is a beam.
Q: What is a steel portal frame?
A: Steel portal frames are a common and cost-effective framed structure that supports buildings.
Q: Where are portal frames used?
A: Portal frames are very efficient in providing support for spaces that require a large amount of unobstructed floor space. They are often used for industrial, storage, agricultural, retail and commercial industries.

Why use retaining wall steel posts?
For a straight and stable steel retaining wall, using steel posts is essential. After all, your walls are only as durable as the elements that keep them upright. We use galvanised steel posts to ensure that your walls can withstand pressure, as well as making sure that your concrete sleepers remain perfectly in place. This secures the overall stability of your wall. Depending on your wall or fencing needs, we offer several steel post designs including SHS steel posts, steel lintels, reinforcing steel, retaining wall steel, T bars, galvanised angle steel and more. Plus, we can also provide metal retaining wall post brackets, which will allow you to connect your fence post to the retaining wall post.
What are the benefits and features of retaining wall steel posts
One of the main benefits of retaining wall galvanised steel posts is that they’re light and easy to install, making them much more convenient than other material variants like timber. This also makes them easy to store, handle and transport no matter the size of your operation. Their simple design, which can include both solid and ribbed angles, is cost-effective, durable and long-lasting – so you can rest assured that your walls and fences are as safe as possible.
What is galvanising and why is it better?
Galvanising is the process of using a layer of zinc to coat steel and other materials. Passing the steel through a molten batch of zinc creates a strong protective layer that prevents steel from being exposed to corrosion and other elements. You can generally identify galvanised steel products by spotting the crystalised pattern on their surface known as a spangle. Items that are galvanised must be completely clean so that the molten hot zinc can bond properly to the material. Steel with heavy mill scale and other rust issues may need to be acid-cleaned to ensure that the galvanisation process will work.

A: Yes, if the surface of the steel is prepared properly galvanised steel can be painted.
QA/QC and Non-destructive Testing Services
QA/QC and Non-destructive Testing Services
What is Non-Destructive Testing (NDT)?
NDT is an engineering technique used to test, analyse and detect flaws in the structural properties of materials, components and whole structures. The benefit of NDT is that it allows you to evaluate structures and materials without causing any damage or impacting the serviceability of the structure.
When should Non-Destructive Testing be used?
NDT provides an extensive investigation into the safety and reliability of your materials and structures. NDT technicians are often called to conduct tests on things like trains, aircraft and motor vehicles, as well as power stations and reactors, pipelines, oil rigs and other working sites where structural failure would be a major problem.
What methods of Non-Destructive testing are there?
There are multiple methods of NDT, these include:
- Radiographic Testing (RT)
- Ultrasonic Testing (UT)
- Leak Testing (LT)
- Acoustic Emission Testing (AE)
- Electromagnetic Testing (ET)
- Penetrant Testing
- Visual and Optical Testing (VT)
- Magnetic Particle Testing (MT)
- Ultrasonic Testing (UT)
- Radiographic Testing (RT)
Why should you use Non-Destructive testing?
The main reason you should use NDT is that it doesn’t cause any adverse effects to your materials or structure during the testing process. However, aside from ensuring structural integrity, there are several other advantages to the process:
- Operational safety: NDT is a harmless technique for humans to perform, ensuring the safety of the engineers during the process
- Worker safety: As well as being safe for operators to conduct, NDT also ensures that any flaws are caught before they can cause harm or fatalities to your employees
- Accuracy: NDT is repeatable, so it allows you to correlate evaluations for clearer results
- Cost-effective: Conversely to destructive testing, NDT allows you to catch issues early and prevents you from having to pay for destroying materials
What is Welder Qualification Testing?
Before the final welding of a product, a sample will be taken to do a Weld Qualification Test. This is done for quality control to ensure that the welding process has met the correct specifications on the project. Welder Qualification Testing can include different types of Non-Destructive Testing, including Ultrasonic Testing, Radiographic Examination, Liquid Dye Penetrant Testing and Magnetic Particle Testing. At Instant Steel Solutions, we test the full range of steel products that we supply so that you know you’re getting the best quality products.
Welder Qualification FAQ:
Q: How do you conduct a welder qualification test?
A: Codes detail the requirements for performance qualifications of welders and there are five types of tests for Welder Performance Qualification, these include:
- Visual Inspection (VT)
- Bend Test
- Macro Etch Test
- Fillet Weld Break Test
- Radiographic Test (RT)
The welder is required to weld a test coupon in accordance with the qualified welding procedure to pass and be qualified.
Q: What is the major difference between a qualified welder and a certified welder?
A: Certified welders are technicians whose qualification is documented by the company the welder works for. Qualified welders are technicians who demonstrate their skills with a particular material or process and bring those skills with them.
Q: What is the highest level of welding?
A: The 6G certification is considered the gold standard of the welding profession. This qualifies technicians to weld 360 degrees around a pipe that doesn't move.
Cold Formed Hollow Section
What is cold rolled steel and how is it different from hot rolled steel?
The key difference between hot rolled steel and cold rolled steel is the process with which they are made. You can probably tell from their names, but hot rolled steel is created with heat while cold rolled steel is crafted at around room temperature. It’s important to understand the difference between the two applications because they impact the performance of your steel products. Also, certain types of steel are better suited to a particular type of application.
Hot rolled steel
Hot rolled steel is a lot cheaper than cold rolled steel as it needs less processing time. It’s created by roll-pressing steel over 1,700˚F, which makes it easy to mould into a final product. Also, because it’s allowed to cool naturally it’s not subject to internal pressure that can result from quick-hardening techniques.
Hot rolled steel is best used on products where material strength is more important than the dimensional tolerances or surface finish. However, if the surface finish is important to you, any scaling can be removed and then we can apply a mirror or brush finish for a nicer overall look.
Hot rolled steel has the following characteristics:
- Minor distortions due to natural cooling
- Mildly rounded corners and edges on some products from shrinkage and natural cooling
- A slightly scaled finish that occurs as the hot temperature cools
Cold rolled steel
Cold rolled steel is essentially a finishing process used to modify hot rolled steel into a more exact or refined state. Once hot rolled steel is completed, it can then be re-rolled at normal room temperature to create more exact dimensions and finishes. This further process is more expensive, however it also provides a more refined product. Cold rolled steel is also generally harder and more durable than hot rolled steel. Cold rolled steel has the following characteristics:
- Smooth, oily surfaces
- Refined finish with closer tolerances
- Uniform tubes with better concentric straightness
- Well-defined bars
LSAW steel pipes vs SSAW steel pipes
Longitudinal Submerged Arc-Welding pipe (LSAW), also known as SAWL pipe, is made through the process of raw steel plates being machine moulded and then undergoing double-sided submerged arc welding. LSAW steel pipes gain weld strength, plasticity, great ductility and excellent sealing from this process. LSAW pipe diameter ranges are larger than ERW steel pipe (approx. 16–60 inches). Two benefits LSAW steel pipes offer are low-temperature erosion resistance and high-pressure resistance.
Spiral Submerged Arc-Welding Pipe (SSAW), also known as HSAW pipe, is created using the same welding technique as the LSAW pipe. However, while LSAW pipes are longitudinally welded, SSAW steel pipes are spiral welded to create a welding line shaped like a helix. SSAW steel pipe diameter ranges are about 20–100 inches and their key benefit is that they have a wide application and are stress-resistant.
Hot and Cold Rolled Steel FAQs:
Q: What is cold rolled steel used for?
A: Cold rolled steel is used for projects where precision is essential because the metal can be formed to exact specifications.
Q: Is cold rolled steel stronger?
A: Yes, cold rolled steels are usually stronger and harder than standard hot rolled steels. The process of shaping at lower temperature increases the steel’s hardness and resistance capabilities.
Q: Can cold rolled steel be welded?
A: It depends on the thickness of the steel. Cold rolled steel is typically less malleable than hot rolled steel so it’s best to consult an expert on the cold rolled steel's ability to be welded.
Q: What is the difference between hot and cold rolled steel?
A: Hot rolled steel is formed at a high temperature and the surface finish is less exact. Cold rolled steel is shaped at room temperature and is more precisely finished.
Q: What is an ERW steel pipe and where are ERW pipes used?
A: ERW steel pipes are round pipes welded from steel plates with longitudinal welds. They are manufactured by low-frequency or high-frequency resistance and are used to transport oil, natural gas and other vapour-liquid objects.
Q: What is ERW pipe specification?
A: ERW pipe maximum OD is 24” (609mm). Larger dimensions pipe will be made in SAW.
Q: What is the difference between ERW and seamless pipe?
A: Seamless pipe is made by extruding the metal to the desired length while ERW steel pipes are manufactured by rolling metal and then welding it longitudinally across its length. ERW steel pipes have a welded joint on their cross-section but the seamless pipe has none.
Reinforcing Steel Bars & Mesh
Types of Reinforcing Steel Mesh Products
To significantly improve the tensile strength of concrete and prevent avoidable damage in structural elements, reinforcing steel mesh provides a handy solution. Manufactured from welded wire fabric or prefabricated steel reinforcement material, these products are easily identified by their rectangular or square grid pattern and are produced in flat sheets.
The four main types of reinforcing steel mesh products include square mesh, trench mesh, rectangular mesh and ute mesh.
- Square mesh – D500L grade ribbed wires
Mostly utilised for reinforcing flat concrete or concrete floor slabs and walls, as well as gates, trailers, shelving and more, square mesh is considered a general-purpose reinforcing product.
- Trench mesh – D500L ribbed reinforcing wires
Trench mesh is a specific type of reinforced steel mesh product used for residential footing trenches and concrete beams. It can be employed in commercial, industrial and residential footing trenches.
- Rectangular mesh – D500L grade ribbed wires
Rectangular mesh is used when additional strength is required for a chosen direction. This type of reinforced steel mesh is used across precast concrete sections, patio slabs, pavement, driveways, shed slabs, warehouses and more.
- Ute mesh
Ute Mesh manufactured to fit safely onto utes and trucks without any illegal or dangerous overhang. Their small size also allows the sheets to be transported easily and by one person if necessary. This type of reinforced steel mesh is perfect for jobs with tight access.
Types of Reinforcing Steel Bars
Just like reinforcing steel mesh, reinforcing steel bars increase the overall tensile strength of the concrete being used. The patterned surface of the bar helps it to bond with the concrete in its compressed state and secures fortification. There are five types of reinforcing steel bars, these include deformed reinforcing bars, threaded bars, pool steel, plain round reinforcing bars and footing bars (Z bars).
- Deformed reinforcing steel bars
Available in diameters of 12mm to 36mm and made from type D500N, deformed reinforcing bars can be cut and bent to meet all project needs.
- Threaded bars
The threading on these reinforced steel bars is specifically designed to be utilised for mechanical splices. It allows for nuts, bolts and various fasteners to be attached to the bar.
- Pool steel
Available in either 6m or 9m diameters, pool steel is an easily shaped and cut bar used in the installation of pools.
- Plain round reinforcing steel bars
Manufactured from type 250N and available in diameters of 6mm to 20mm, our plain round reinforcing bars are made to Australian quality standards AS4671-2001.
- Footing bars (Z bars)
Shaped like the letter Z, these reinforced steel bars create a positive connection point between concrete slabs and their corresponding footing beam reinforcement.
What are the Benefits of Reinforcing Starter Bars?
Available in a variety of lengths, reinforcing starter bars can be used to secure footings or concrete slabs to walls. The main benefits of starter bars are that they’re easily manufactured to suit project requirements, have readily available stock lengths, are great for smaller construction projects, and come in a wide range of diameters and lengths.
Reinforcement Starter Bars FAQ:
Q: What is reinforcement in steel?
A: Reinforcement is a tension device used to strengthen and support the concrete under tension.
Q: What are the types of reinforcing steel?
A: There are several types of reinforcing steel, however, the two main types of reinforcing steel are reinforcing steel bars and reinforcing steel mesh.
Q: What is deformed reinforcing steel bars?
A: Deformed reinforcing steel bars have a rougher or ribbed surface that improves the bond between the concrete and the steel, which improves the overall tensile strength of the concrete..
Q: How do you calculate reinforced steel bars?
A: The density of mild steel is 7850kg. Adding up the unit weight of each bar will allow you to calculate the weight of your steel bars. The formula should be:
- Weight of steel bar = volume of steel bar x density of steel
- Weight of steel flat bar = (length x width x thickness) x 7850
Q: What are starter bars in construction?
A: Starter bars are defined as steel reinforcing bars embedded into concrete and projected through a construction joint to bind adjoining masses of concrete together.
Welded Beams and Welded Columns
Wielded Beams & Columns
The Benefits of Welded Beams
For a structure that’s robust and optimised for performance, high-quality welded beams provide remarkable support. Welded beams are produced from a web and two flanges that are combined through deep penetration fillet weld to create a formidable product that can handle extraordinary loads. With a dramatically improved strength-to-weight ratio, welded beams are up to 20% stronger than their standard counterpart.
Part of what makes welded beams so effective for construction is how they can be used on a vast range of projects. From large-scale engineering work and residential jobs to general manufacturing operations, welded beams are an adaptable material for projects where a high strength grade is paramount. When planning the fabrication of welded beams, the particular dimensions of a beam’s flanges and web will be determined by the load requirements spread across the beam’s length.
Welded Columns Provide Maximum Strength
Welded columns feature virtually the same advantages as beams, but there are a couple of significant differences. Like beams, welded columns are made from three individual parts that have been fused together to create a resilient final product. However, the three sides of a welded column are all equal in length compared to the wider web plate typically seen in beams.
With both welded beams and columns often referred to as I-beams or H-beams depending on their orientation, these essential construction materials provide amazing weight-bearing benefits. Alongside commercial and residential projects, welded columns are often used in the mining and transport industries. For example, you can find welded columns forming a supportive base for building cranes.
Welded Beams FAQ:
Q: What is a welded beam?
A: A welded beam consists of three individual sections of steel – a web, a top flange and a bottom flange. These segments are merged together with deep fillet welds to create an incredibly robust building material.
Q: What are H-beams used for?
A: H-beams are a highly adaptive structural element that can be used across a vast range of construction and industrial purposes. From extensive commercial projects to bridges and trailers, H-beams are excellent for carrying extra-heavy loads due to their thick central web and wide flanges.
Q: What is the difference between an S-beams and AW-beams?
A: While AW-beams have standard parallel flanges, S-beams are designed with tapered flanges to provide additional strength. S-beams can be used for a variety of projects, but are especially common in residential projects, commercial construction and other high-performance products such as truck bed frames.
Q: Can you join steel beams together?
A: Yes, steel beams can be joined together either through welding or bolting. However, this choice is going to be heavily dependent on the precise circumstances of your worksite. To do so, a splice plate can be connected to the flange or web to link two steel beams.

Australian standards for hot rolled steel
The dual Australian–New Zealand standard includes:
- AS/NZS 1594: 2002 (reconfirmed without changes in 2016)
- Hot rolled steel flat products
- AS/NZS 3678:2016: Structural steel – hot rolled plates, floor plates and slabs/li>
- AS 1548-2008 (R2018): Fine grained, weldable steel plates for pressure equipment.
The aim of the standard is to ensure that the needs of the product are met correctly in terms of dimensional tolerances and material requirements. For instance, to meet the standard, hot rolled steel must be produced at a continuous mill in up to 2 m widths and 8 mm thickness for formability and extra formability grades (16 mm for any other grades).
The benefit of the standard is that it allows for a number of different grades of steel to be produced by hot rolling, as long as certain requirements regarding structural grades and formability, chemical composition and mechanical properties are met.
