Corrugated sheets are thin metal panels that feature a repetitive wave-like pattern. This unique corrugation increases the structural strength and load-bearing capacity of the material, making it much stronger than flat sheets of the same thickness. They are typically made from galvanized steel, aluminum, or pre-painted steel, depending on the intended use.



The most common types include steel corrugated panels for industrial roofing and PPGI or GI corrugated sheets for decorative and weather-resistant projects.
