Corrugated aluminum sheet is a popular category of non-ferrous metal. Convex patterns are applied on the surface of rectangular plates. The corrugation gives prefabricated structures an anti-slip effect. Resistance to mechanical stress. Due to the peculiarities of processing blanks, plates with protruding patterns are 7 times harder than smooth metal. Low cost. Corrugated aluminum sheet, the price of which is low, replaces more expensive building, finishing, and decorative materials. Easy processing. Hot-rolled, cold-rolled plates are subject to welding, stamping, cutting, profiling. In addition, the polymetallic material is resistant to corrosion and temperature extremes. Environmentally friendly constructions have a long service life.
