The chromium in stainless steel serves the same purpose as the zinc on galvanized steel, except that the chromium is mixed throughout the steel. Galvanized steel is coated with a thin layer of corrosion-resistant zinc that may eventually wear away due to rust caused by moisture that may penetrate through a deep scratch caused by environmental impact or mechanical damage. Modern steel siding may be made from galvanized steel or stainless steel – a distinction that influences its vulnerability to rust. Barn designs have since evolved based on aesthetics and available resources, but most of them still incorporate steel as a siding material, and many modern barns are constructed almost entirely from steel. The buildings proved extremely durable, as they still dot the rural American landscape today. One popular result was structures known as pole barns, which used debarked, de-limbed sections of tree trunks to support the outer walls and roof, which were composed of galvanized, corrugated or grooved sheet steel siding.
