Flame cutting is a type of thermal cutting method based on a combination of oxygen and fuel, such as acetylene or natural gas, which generates an intense heat. This flame is directed onto the surface of the steel plate, causing the exposed metal to be split into two.

The flame cutting process starts with marking the metal areas that you want to cut, which is a necessary step to establish the cutting lines of the desired shapes. Next, the flame cutting machine is pre-programmed to follow pre-established cutting lines.

The technique of flame cutting is renowned for its ability to precisely slice through thicker steel materials, making it possible to produce complex shapes with intricate designs. It is often used to produce structural parts and heavy plates because it has the ability to make precise and clear cuts hence reducing the need for any subsequent rework.

Another hallmark of flame cutting is its versatility. As a matter of fact, this technique is compatible with a wide range of steel grades and alloys.

Plasma cutting is a fabrication process which uses the heat and pressure generated by a constricted electric arc to melt and cut metal. During this process, an inert gas, usually nitrogen, is passed through a nozzle at high speed generating a jet of hot plasma.

This plasma can reach temperatures of up to 20,000 degrees Celsius, and when it hits the workpiece, it melts and blows away the metal, making a precise and clear cut.

One renowned advantage of plasma cutting is the ability to make precise and clear cuts. This reduces the need for any subsequent rework and allows for the creation of ready-made items, hence reducing lead time and labour costs.

Type of cleaning process aimed at removing contaminants and oxides from the surface of the metal. It is a chemical treatment that is carried out before any other subsequent process such as galvanising and painting.

The most widely used technique consists in immersing coils in an acid solution (normally sulfuric acid or diluted hydrochloric acid) for a specified time. Once the process has been completed, the coils are accurately rinsed to remove any impurities. In some cases, it may be necessary to apply a passivation solution to protect the material from future corrosion.

Coils are the starting point of CTW processing. During this process, steel coils are pulled by a recoiler to create narrower strips.

Finally, a suitably sized recoiler winds the different strips into separate coils.

The flattening process starts by feeding the steel coils into the straightening press. This machine is equipped with high precision rolls or cylinders which apply pressure onto the coils, crushing them and levelling them uniformly.

The flattening process eliminates any potential deformations or corrugations that may affect the coil strips, thus achieving a perfectly flat surface. This flatness is an essential requirement to carry out any subsequent types of processes, such as rolling, mechanical processing, and sheet processing.

The flattening of steel coils is a crucial step for the creation of high-quality steel sheets that can be used in a wide range of industry, such as automotive, construction, electronics, and many others.

The blanking process starts by feeding the steel coils into a press and die. This machine has the ability to produce steel sheets with tighter tolerances in terms of thickness, width and angles.

The flatness of steel components is an essential requirement to carry out any subsequent types of processes, such as rolling, mechanical processing, and sheet processing.

The blanking of steel strips is a crucial step for the creation of high-quality steel sheets that can be used in a wide range of industry, such as automotive, construction, electronics, and many others.

Sandblasting is a mechanical surface treatment consisting in the cleaning of metallic surfaces in preparation for painting. This process involves removing any impurities, corrosion and dirt that may have accumulated on the steel plate to improve coating adhesion and ensure a longer lifespan of steel framed structures.

The sandblasting process starts by preparing the heavy steel plates which are placed inside a professionally equipped chamber known as sandblaster. A stream of sand and abrasive material is then forcibly propelled against all metallic surfaces.

The abrasive nature of sand means that it can effectively remove layers of oxides, old paint and rust thus creating a clean and rough texture which ensures optimum adherence of the protective coating. After the sandblasting is finished, it is essential to thoroughly clean the surface to eliminate any remaining dust or dirt.

The first step of the welded tube profiling process consists in selecting the tubes, which can be made through spiral welding or longitudinal welding. These tubes have a high resistance and are ready to be converted into custom-made profiles.

Subsequently, the tubes are fed into the profiling machine as they pass through a series of rolls and special blades. These gradually bend the tubes moulding them into the desired shape. During the profiling process, the workpiece is altered by controlled plastic deformation, thus acquiring a specific cross-section.

It is possible to adjust the profiling machine to create a wide range of profiles, such as C-beams, U-beams, L-profiles, and many others. Profiling is a versatile technique that can create steel shapes ready to be used in a range of structural and decorative applications. It also reduces the need for additional mechanical rework because the tubes are directly converted into the desired shape.

• Scotch brite → involves the use of abrasive pads to achieve a satin and homogenous finish on steel surfaces. This technique improves the aesthetic quality of the metal sample, thus making it less prone to show marks and stains, while also increasing corrosion resistance.
• Satin finish with sandpaper on coils/plates → consists in using sandpaper to achieve an opaque and uniform finish on steel surfaces.
• Flowering finish on plates → involves the use of specific pads to create a decorative repeat pattern of overlapping circles.
• PVC coating on coils/plates → consists in adding a protective PVC coating on the metal surface. This coating protects the material from scratches, damage, and corrosion agents during shipment and fabrication.

This is a combined process which results in the removal of the internal thickness of the metal layer from a welded or unwelded tube to produce a dimensionally accurate workpiece as well as reducing surface roughness down to Ra: 0,4my and below.

Compared to other types of technology, this process ensures the creation of high-quality products, compliance with industry standards, and increased productivity.
