Our Plasma Cutting Capabilities.
At Colstan Profiles, our plasma cutting service is ideal for both steel profiling and the etching of parts and components.
- We operate a CNC machine with a cutting bed of 9m x 3m, allowing us to handle larger workpieces with precision.
- Our equipment is capable of cutting material thicknesses ranging from 0.5mm to 300mm, making it suitable for both thinner sheets and thick steel sections.
- We maintain tolerances of +/- 1.0mm on the top face, depending on the thickness and length of the steel.
Additionally, we stock a wide variety of steel in different grades and thicknesses, ensuring competitive lead times for all projects.

Plasma Cutting Frequently Asked Questions:
Plasma cutting is a process that uses a high-temperature jet of ionised gas (plasma) to cut through electrically conductive metals. By heating gas to extreme temperatures, the plasma jet can melt and blow away metal, creating precise cuts. Plasma cutting is widely used in industries such as automotive manufacturing, construction, and metal fabrication, thanks to its efficiency and ability to handle a variety of metals like steel, aluminium, copper, and brass. Compared to other methods like laser or water jet cutting, plasma cutting is faster and more cost-effective, especially for thick materials.
For more information on What is plasma cutting?, click this link for more.
A plasma cutter works by using electricity to heat compressed air into plasma, the fourth state of matter. The cutter generates an electric arc between the electrode inside the machine and the workpiece. This arc ionises the gas, turning it into a plasma jet that reaches temperatures of up to 30,000°C. As the plasma jet contacts the metal surface, it melts the material, and the force of the jet pushes the molten metal away, creating a clean and precise cut. Plasma cutters can be operated manually or integrated with CNC systems for automated, highly detailed cuts.

- Speed and Efficiency: Plasma cutting is much faster than other metal cutting methods like oxy-fuel, particularly on thinner materials. It’s also efficient on thicker materials, cutting faster than laser in many cases.
- Precision: Plasma cutters deliver clean, precise cuts, even on intricate designs or detailed metal components, making them useful for applications ranging from industrial manufacturing to artistic metalwork.
- Versatility: Plasma cutting works on a wide range of metals, including steel, stainless steel, aluminium, copper, and brass, making it suitable for various industries.
- Cost-Effective: Compared to other cutting methods like laser or water jet, plasma cutting is more affordable. Both the machinery and the operational costs (energy consumption and gas) tend to be lower.
- Portability: Many plasma cutters are compact and portable, allowing for on-site cutting in construction, repair, or salvage operations.

- Limited Material Types: Plasma cutting can only be used on conductive metals. It won’t work on non-conductive materials like plastics or ceramics, unlike water jet cutting, which can handle almost any material.
- Rougher Edges on Thick Metals: While plasma cutting is precise, it may leave a slightly rougher edge on thicker materials, particularly if the machine isn't adjusted properly. Additional finishing may be required for smoother results.
- Noise and Fumes: Plasma cutting can be noisy, especially when cutting thicker materials, and it generates fumes, particularly from certain metals. Adequate ventilation or a fume extraction system is required in indoor environments.
- Energy Consumption: While it’s more efficient than oxy-fuel in terms of speed, plasma cutting consumes more energy, particularly on larger or industrial machines.
The primary difference between laser cutting and plasma cutting lies in the precision, method of cutting, and the materials each process is suited for.
Laser cutting: uses a concentrated, high-powered laser beam to cut materials. This beam is extremely precise and capable of cutting intricate patterns and fine details, making it ideal for thin materials or applications where tight tolerances are essential. Laser cutters typically have a smaller kerf, which refers to the width of the cut, meaning they leave a cleaner and narrower cut line compared to plasma.
Plasma cutting: on the other hand, uses a high-energy plasma jet to melt through metals. Plasma cutters are powerful and capable of cutting through thicker materials much faster than lasers, especially on conductive metals like steel, aluminium, and copper. However, plasma cutting tends to have a larger kerf and may produce a rougher edge, particularly on thicker metals, which can require additional finishing for smoothness. While plasma cutting is less precise than laser cutting, it is more cost-effective and versatile when it comes to cutting thicker materials.
Key differences:
- Precision: Laser cutting is more precise, making it better suited for fine, intricate cuts. Plasma cutting is powerful but less focused, resulting in a larger kerf.
- Speed: Plasma cutting is generally faster when cutting thicker materials, while laser cutting excels in speed for thin materials and delicate designs.
- Materials: Laser cutting can work on both conductive and non-conductive materials, such as metal, plastic, and wood. Plasma cutting is limited to electrically conductive metals.
- Cost: Plasma cutting is often more affordable for thicker materials and large-scale projects. Laser cutting tends to be more expensive, particularly when cutting thicker metals.
Each method has its strengths, and the best choice depends on the material, precision requirements, and the specific application. Contact us to see which service best suits your needs.
