Welding of steel sheets or steel plates gives a special resistance to the structural elements. Their application is made by using a two-component epoxy resin between the concrete surface and the metal lamina. The concrete surface must be suitably prepared by grinding, cleaning and leveling before the adhesion.
In special conditions such as welding the metal lamina, the application of an epoxy resin is made by injector, after setting and fixing the lamina so that the resin won’t blast.
