The accuracy and quality of the mounting of the panels is ensured by the correct installation of the supporting structure. When installing the panels, according to the project, there is a need to cut the workpieces to the required size. This occurs due to the fact that the manufacturer supplies the workpieces of a certain geometric shape, and the radius or any other irregular shape is given the panel immediately before installation in the construction site. At the end of the work, the panel is cleaned from the safety film (its presence is provided for by the rules for storing and transporting panels), degreased and cleaned of construction dust with a weak solution of chemical reagent.
