A system of hangers made of steel with a protective coating applied by the Sendzimir method is a product on which the protective zinc coating was applied to the sheet steel before manufacturing. The thickness of the protective coating varies from 10 to 22μm. Climate execution of the products is UHL2, which provides for operation indoors and under a canopy, at an operating temperature from -80 to +150°C. This is a load-bearing element of the structure, attached directly to the wall. The advantage of this element is its versatility; a KNS line can be assembled on its basis both vertically and horizontally.
