Laser Cutting
Mild Steel
We laser cut steel sheet in thicknesses between 0.7mm and 40mm.
For 35mm and 40mm, our tolerances are + / -0.50mm, this is in line with ISO guidelines.
Steel is made up of carbon and iron, with much more iron than carbon. It contains a low amount of carbon making it very strong, with a high resistance to breakage. Mild steel, as opposed to higher carbon steels, is quite malleable, even when cold, meaning it has high tensile and impact strength compared to higher carbon steels which usually shatter or crack under stress, while mild steel bends or deforms.
Mild steel is widely used in construction because it can be easily machined compared to harder steels and is also easy to weld, both to itself and to other types of steel. It takes on a nice finish and is polishable. It cannot be hardened through heat treatment processes whereas higher carbon steels can.
Maximum Sizes
The maximum sheet size for most materials is 3000mm x 1500mm, a 10mm border is required around the outside, so the maximum part size we can cut is 2980mm x 1480mm. There are exceptions to this rule – these are marked in the materials tables.

We laser cut steel in these grades
Cold Rolled Steel is known for being extremely ductile. Often abbreviated to CR or CRS, it is excellent for applications requiring high precision, it holds tight tolerances and retains few surface imperfections. It is non-shrinking and non-creeping at ambient temperatures.
CR4 contains a maximum of 0.08% carbon, a maximum of 0.4% manganese, 0.03% of Sulphur at most and a maximum of 0.02% phosphorous with negligible impurities.
Applications for laser cut CR4 Steel
CR4 is ideal for use in home appliances and metal furniture. Items such as metal filing cabinets and school lockers are commonly made of this grade of mild steel before being powder coated or painted to provide a robust, corrosion resistant coating. In construction, Cold Rolled Steel is a common material for building industrial units, and garages.
S275 is a low carbon steel. Low carbon steels are defined by having less than 0.3% carbon content. Low carbon content prevents heat treatment from having much of an effect, meaning that S275 steel is excellent for machining, welding, and forming, making it extremely useful as a general purpose steel.
S275 steel usually has small amounts of other alloying elements, including manganese, sulphur, phosphorus, and silicon. These elements influence the metal’s strength, ductility, corrosion resistance, and machinability. S275 contains very little nickel or chromium, so it lacks corrosion resistance.
Our S275JR Material from 4mm to 10mm is pickled and oiled as standard. All parts cut in 6mm and below are nitrogen cut to give you a clean, oxide free finish, ready for welding, painting or coating.
Applications for S275 Steel
S275 steel is used in many industries for a variety of applications because of its relatively low cost. The mechanical properties of S275 steel make it particularly suited to industrial and structural applications such as bridges and buildings because of its strength and toughness. S275 steel is also popular for automotive, construction and heavy equipment applications.
S355 structural steel is a high-strength low-alloy European standard structural steel the chemical and mechanical properties are ideal for machining and forming.
All of our S355 material is certified to JR and J2 as standard and all material certificates are available.
The following letters and numbers explains the steel grade S355 meaning.
S – stands for “structural steel”
355 – refers to the minimum yield strength value in thicknesses up to 16mm. The yield strength reduces in thicknesses greater than 16mm for flat products.
JR – means the impact energy value is minimum 27 J at room temperature (20˚C).
J2 – the minimum impact energy value is 27 J at -20˚C.

Applications for S355 Steel
S355 is often used in the most demanding environments. Typical applications include: Structural steel works, bridge components, offshore structures components, power plants, mining and earth-moving equipment.
Laser cut steel sheet
Laser cut steel components make up 81% by weight of the components we produce.
Laser cutting is a fast and cost-effective way to obtain very accurate steel components.
Our turnaround times mean that you can quickly put together prototypes for testing and product development until you perfect your product.
It is also the perfect process for high volume production of identical, precision steel components. The high tolerances of laser cutting mean that the last component off the machine will be identical to the first.
As laser cutting specialists, we always make sure that we source the best material and our equipment is set up to achieve the best laser cut steel results. Corrosion can affect the quality of the cut, so steel must be stored carefully to avoid this. We only source the best quality materials and our stock is stored indoors until it required. Any laser cut steel will have a slight burr but a precise setup will reduce this.
