What is CNC Plasma Cutting?
CNC Plasma cutting is a technique used to cut contours and shapes through plate metal, flat metal sheets, pipes, and structural beams.
In basic terms, plasma is gas heated up by an electric arc to form a beam capable of melting metal upon contact.
The high heat of the plasma combined with the intense pressure of the gas stream forms the precise cutting mechanism. While the plasma melts through even thick materials, the gas pressure removes excess molten material.
What Other Processes Are Typically Used Alongside Plasma Cutting?
Plasma cutting can be employed alongside the following processes:
Machining
Plasma cutting can act as the bulk material removal operation for machinists. Thanks to the high level of cutting accuracy offered by plasma devices, it is possible to reduce the amount of machining required for processes such as tapping and drilling.
Fabrication: Welding, bending, and rolling
Plasma cutting can be used in fabrication processes such as bending, welding, and rolling. If you’re manufacturing a pipe with a large diameter, for example, it is possible to cut pipe end profiles with a plasma cutter, as well as cut junctions and holes in flat plate material. This can reduce the need for further shaping when the flat profile is rolled and welded.
Edge Preparation
CNC plasma cutting machines are capable of creating contours, bevelled edges, and countersinks in stock materials, including three-dimensional and flat sections. This could prove useful in projects where weld preparations are needed, or you want to form angular junctions from plasma-cut pipes.
Cleaning & Reservation
Sometimes, you need to cut a crust or skin from processed materials. In such cases, plasma cut profiles can be cleaned using abrasive blasting or pickling techniques to create a refined finish.
Why Choose Plasma Cutting Over Laser Or Flame Cutting?
Plasma cutting has a range of fantastic benefits that make it preferable to flame and laser alternatives, including:
- It produces cleaner edges
- It can cut smaller holes
- It can cut through thicker materials compared to lasers
- It can be used to cut highly reflective or polished materials
Designing Custom Fabrication Products
Custom fabrication is invaluable for a huge variety of projects. Whether you need precision-produced joists or frames for construction, railings or steel deck, or structures for a garden project our team can help you bring your vision to life.
We offer computer-assisted design (CAD) for all our projects and will deliver a full set of CAD drawings in the first stages of design. This means you can be confident we understand your vision and that the finished product will meet your expectations.
Cutting To Shape And Size
The next stage of your project is to cut the steel to shape and size. For most projects here at Hardrok Engineering we use plasma cutting. This is a process that uses heated plasma gas to create cuts with clean edges and minimal ingress. It’s good for all materials and especially good for highly polished surfaces.
Because we’re a family firm we are able to be completely flexible and our years of skill mean we will use alternative methods if the project needs it. We can use a range of techniques including machining, bending and rolling.
Welding & Fabricating

We use plasma cutting to enhance our welding. We can create precision-shaped end profiles for pipe welds and junction holes, with minimal need for additional shaping.
Plasma cutting can also be used to create bevels or countersinks to form angular junctions with plasma-cut pipes. Plasma cut profiles can be cleaned using traditional pickling or abrasive blasting techniques.
Adding Finishing Touches
Finishes are used to prevent corrosion. There are various types of finishes available, each with different properties.
Machining
This type of finish is a zinc phosphate paint that is applied in two layers for maximum longevity. It reduces corrosion by inhibiting the formation of anodes on the surface of the fabricated steel.
Galvanisation
Galvanised steel is immersed in molten zinc, which then forms a paintable protective coating. It’s a process that is very reliable and can be used on a wide range of objects of all shapes and sizes.
Powder Coating

Using an electric charge, dry powder is fused to fabricated steel. The coating is then heat treated to create a dry finish. It’s an excellent choice to disguise imperfections.
Installation of Steel Products
As well as creating, HardRok Engineering will deliver and install your steel product. We’ll discuss the whole project as part of our design visits and undertake all the necessary logistics to get everything perfectly in place.

Professional Steel Fabrication Tailored for the Plumbing Industry
Steel fabrication plays a vital role in the success of modern plumbing projects. From custom brackets and frames to specialised pipe supports, having access to high-quality steel solutions ensures plumbing systems remain secure, efficient and built to last. By working with a team that understands both steel and plumbing, clients gain the benefit of seamless integration across all project stages.
Clients looking for custom steel fab in Mount Isa expect reliable turnaround times, accurate workmanship and solutions tailored to the real-world challenges of site-based work. With fabrication services purpose-built for the plumbing sector, each product is made to support long-term system integrity and reduce future maintenance needs—saving time and money over the life of the project.
Save Time & Costs with Plasma Cutting
Precision is everything when it comes to fitting fabricated components into a plumbing system. CNC plasma cutting and machining services provide unmatched accuracy, helping to eliminate costly on-site adjustments and reduce the chance of installation delays. Every cut is clean and consistent, meaning materials arrive ready to install—streamlining the overall construction process.
Beyond accuracy, these services allow for faster turnaround and greater efficiency. When components are machined to exact specifications off-site, projects stay on track and labour costs are minimised. For plumbing contractors working on tight schedules, this level of readiness can make a real difference to project delivery. It also reduces the reliance on on-site tools or improvisation, which helps ensure installations are safe, compliant and done right the first time. With fewer errors and stronger consistency, both time and material usage are optimised—benefits that directly impact your bottom line.
Fabrication That Fits Your Scope
Every plumbing site presents unique challenges—tight spaces, unconventional layouts and varying access requirements. Custom steel fabrication allows each piece to be crafted to fit its exact environment, ensuring installations are safer, faster and more reliable. Whether it’s a one-off bracket or an entire support framework, tailored fabrication removes guesswork and reduces on-site improvisation.
Plumbers and builders benefit from knowing their materials have been prepared specifically for the job at hand. With access to custom steel fab in Mount Isa, clients enjoy the convenience of local support combined with the precision of made-to-measure steelwork. This not only saves time but also minimises errors, helping every project progress with fewer setbacks.
Enhanced Durability Through Edge Preparation
In plumbing, longevity is just as important as performance. Proper edge preparation, cleaning and surface finishing play a major role in how steel components hold up over time. These processes reduce the risk of premature corrosion, ensure smoother joins and create better bonding surfaces for coatings or welds—leading to stronger, longer-lasting installations.
For clients managing ongoing infrastructure or large-scale commercial plumbing jobs, investing in quality finishing upfront helps prevent issues down the track. Partnering with a provider of custom steel fab in Mount Isa means knowing every detail—from the cut edge to the final finish—has been handled with care. That level of precision contributes directly to a system’s resilience and lifespan.
Protection with Galvanisation & Powder Coating
Plumbing systems are often exposed to moisture, chemicals and temperature fluctuations—making corrosion resistance essential. Galvanisation and powder coating offer a protective barrier that keeps steel components in better condition for longer. This added durability means fewer breakdowns, less frequent replacements and more reliable performance over time.
