For the installation of steel in any structure, there is a complex prior process of working on the materials.
In this post we will explain to you what the treatment of steel sheets is like, from its manufacturing to the final installation, through its transformation and the different ways in which it is worked.
Now, let's start at the beginning: What is the first step in creating steel sheets?

Manufacture and transformation of steel sheets

of the process of creation of steel We already talked in detail in a previous post. We also know that the sheets are flat and have measurements that range between 0,15 mm to 10 mm thick. Now him target is to convert them into parts and structures of different shapes such as, for example, chassis, casings or supports, among other elements.

The first thing that has to be done is the removal of material. It involves cutting pieces of the raw material (steel) to produce the shape you want. To obtain a product with high precision and quality, traditional cuts and advanced technology are usually used.

laser cutting

It's a laser beam high-density that is directed at a specific piece to melt, vaporize or burn it, thus cutting the material. Therefore, laser cutters are used to cut, drill and engrave.

There are three types of laser:

  • CO2 (carbon dioxide). High energy efficiency, It is used when you want to cut thin material, as well as engrave and drill.
  • Nd (neodymium). It has a high energy, however, it has a low repetition efficiency. It is used for engraving, drilling and welding.
  • Nd-YAG (doped yttrium aluminum garnet). It has very high power, therefore, it is suitable for cutting thicker materials.

Laser cutting is used to cut sheets that are made of steel, however, it is also suitable for other types of materials. We recommend using it to cut thin pieces with a thickness of 6 mm.

Water jet cutting

A nozzle is used to focus a stream of water with a very high pressure to cut a piece. For materials such as steel, a mixture of water and abusive granular substances is used.

This type of cut is ideal for cutting sheets of different thicknesses and all types of materials. Furthermore, it is the most accurate, with tolerances between 0,005 mm and 0,1 mm.

One of its most notable advantages is that it does not generate heat compared to other types of cuts.

Plasma cutting

It works by applying heat and energy to a gas so that it can be converted into plasma. Subsequently, a very hot plasma jet is accelerated by means of an inert gas that leaves the cutting nozzle to reach the piece. The plasma makes an electric arc with the piece, melting it and cutting it. As it is an electrical procedure, plasma cutters can only work with materials that are electrically conductive.

This technique can cut very thick materials, up to 200 mm for steel.

Deformation

The controlled application of force to bend or shape sheets made of steel until you get the shapes you want. The deformation process includes: bending, forming, stamping and stretching. For this, dies, hydraulic and magnetic brakes are used.

Mounting methods

The last step is to join the pieces that have been processed to form a final product. Assembly processes include welding (including brazing), riveting, and the use of adhesives.

The assembly of the structure with the Steel sheets It has to be carried out in accordance with a previously established installation program, ensuring stability and security at all times.

All the  structures with plates of steel  They do not require special techniques regarding installation. However, special attention must be paid to the sheet metal manufacturing process so that the elements are straight and there are no distortions in the welds. Furthermore, it must also be safe against assembly loads, always maintaining the shoring until its removal is safe.

Aspects to consider

Each part of the sheet steel structure has to be aligned once it has been assembled. Therefore, permanent connections cannot be made between the sheets until they have been aligned, level and connected temporarily with a sufficient part of the structure. The objective is to ensure that no element can be displaced during subsequent assembly or alignment of the rest of the structure.

El sheet alignment It can be done with wedges. These must be secured when there is a danger of them coming loose; however, the wedges must also be made of steel. They must be of similar duration to that of the structure and with a minimum thickness of 2 mm if used in an outdoor environment. If shims are used for the alignment of structures with a coated material they must be similarly protected to provide a specific life.

If the installation requires welding on site specific procedures must be followed for this (guidelines EN 1090-2 y EN 1011-3 ).

In summary, the Steel sheets They follow an entire process that ranges from its creation to the final installation in the corresponding structure. If you need sheets made of steel or any type of advice, do not hesitate to contact us. contact us.
