Manufacturing of various metal structures is a multi-stage process that takes place in a factory. Before assembly, the products must be treated with paints and varnishes. Although hardware is extremely strong in structure, its main disadvantage is its susceptibility to corrosion.
Proper cleaning and painting will prolong the life of metal structures.
Correct painting of metal structures is done according to generally accepted technology. Professionals can use special tools and paints and varnishes. Industrial paints differ from household paints, since the main purpose of their use is to reduce the risk of damage to metal structures. Paints and varnishes are also used in the production of steel enclosures for equipment such as generators, pellet boilers and production machines.
Professionals use three methods of painting, with which you can protect the surface from corrosion and change the appearance of the structure. The most popular method is spraying. This is an affordable and cheap method of applying paint. In large industries, a special powder coating is used, along with which it is recommended to carry out the galvanizing procedure. Due to the automation of the painting process, hand painting, that is, the third method, is used only at the stage of decoration. In the process of painting, various identification marks and inscriptions can also be applied.
The metal surface to be treated must be cleaned before the paint is applied in any of the above forms. During the repair, areas with rust are removed. If the structure is completely new, it must be free of any dirt, dust and other debris that appears on the surface during processing. Cracks and irregularities are also removed. The metal must be completely dry, only after that it is allowed to apply the first coat of paint. It is required as a primer. In most cases, you will need a few more layers to solidify the color.
