Water Jet Cutter

One of the most versatile manufacturing technologies today, our abrasive waterjet cutting machine allows fast and extremely accurate cutting of metals, composites, glass, ceramics and more.

What is Water Jet Cutting?

Water Jet Cutting involves using a jet of water under very high pressure (50,000 psi) through an ultra-fine nozzle to cut through virtually any material. Abrasives are added to the water to increase the power of the jet of water allowing it to cut through 100mm steel plate. The cutting is controlled by sophisticated software that can guarantee cutting to an accuracy of 0.1 of a millimetre. The machine will cut as accurately as it can be drawn. This means sophisticated and complex parts drawn using CAD software can be produced with ease. The level of accuracy can also be controlled so that applications that don’t need a very high level of finish can be done at a faster speed and lower cost.

What materials/ sizes can be cut?

The Water Jet machine can cut through all metal plates stocked by Steel Industries, being Carbon/Mild Steel plate (1.5mm – 90mm), stainless steel plate (0.55mm – 16mm) and Aluminium Plate (0.6mmm – 12mm). In addition to metals other materials such as rubber (for gaskets etc), wood, stone (kitchen bench tops etc) and glass can also be cut.
The machine can take plates up to 1500mm x 3000mm in size. Any shape that fits within this size can be cut.

What are the benefits?

  • Accuracy - Material can be cut accurately to intricate designs and shapes.
  • Speed - Thinner softer materials can be cut extremely quickly.
  • No Heat - Unlike traditional flame, plasma or laser cutting processes, there is virtually no heat in the water jet cutting process. This preserves the integrity and also avoids any warping and distortion of the material being cut.
  • Finish - The Water Jet Produces a smooth finish meaning no further machining or grinding is required.
  • Environment - No hazardous waste, heat or gases are produced, substantially reducing any impact on the environment.

What do I need?

  • Design - CAD files can be accepted directly into the machine software. Drawings can be scanned to PDF files which can be converted into drawing files. CAD files can be created from sketched details by Steel Industries.
  • Materials - Materials to be cut can be supplied by Steel Industries. Specialist and other materials can be provided by the customer.

How Much does it cost?

The cost of cutting using the Water Jet machine is directly related to the time the machine takes to perform the cut. The time taken depends on the material being cut and the finish required. These parameters are entered into the machine and the machine will then determine the speed it needs to travel at and therefore the time required.

A quotation can be provided once the material and design has been specified. Setup costs will vary depending on complexity and what has been provided by the customer.

Steel Building Frames

Our FRAMECAD® system is the fastest way to design and build strong, durable steel framed buildings easily and efficiently.


The Process begins with a concept, an architects design or engineering drawings.


The entire building or frames are detailed using FrameCAD Software to comply with relevant building codes. The completed file is electronically sent to the FrameCAD manufacturing equipment.


The FrameCAD manufacturing equipment then creates each component of the building frame individually, labeling them according to their location in the frame for error free construction.


The assembly process usually takes place at the factory. Each component is screwed together to form the panels and trusses. For remote sites components can be pre-packed for on-site assembly.


The completed panels and trusses are then transported to site. Due to the light weight, all assembled panels and trusses can be easily handled manually without the need for expensive lifting equipment.


Once on site the panels and trusses are unloaded and positioned for rapid and accurate assembly using semi-skilled labour.


FrameCAD Computer Aided design software allows for fast Production - including pre-punched, dimpled fastening holes, notched lips, punched web holes, punched services holes, and all parts individually labeled. All components are preassembled in the factory allowing very fast erection on site by semi-skilled labour.


FrameCAD Computer controlled production is accurate to +/- 0.5mm. This ensures fames are straight and square. As well as providing a well built building, this makes it easier for later tasks such as installation of the linings, windows and doors.

Durability & Materials

Light weight steel framing is long lasting and will not warp, bend or rot. It is also termite proof and is not combustible. Steel Industries stocks galvanized coil stock of .75mm, .95mm, and 1.15mm.  Our .75mm is the most popular and lowest cost being suitable for single story walls and trusses for homes and light industrial buildings as well as internal walling for apartments and office complexes.  Our .95mm is used to meet design requirements for longer span trusses as well as multi storey buildings.  The 1.15mm is also used in multi storey buildings and in making floor panels which gives a lower cost option than using purlins as joists.


Light weight steel framing is a low cost solution compared to timber. It requires less material to achieve the same strength and there is minimal wastage due to the design and manufacturing process. It can be installed at a lower cost by semi-skilled labour and is more economical to transport.
