Corrugated galvanized roofing sheet begins as carbon steel sheet and is then pressed into a three-dimensional pattern by a series of rolls during the cold roll forming process, which is known as corrugation. Different roll die arrangements produce different types of corrugation, including waves, squares and angles. Cold rolling results in a product that is thicker, stronger and has a better appearance than hot formed steel. The finished sheet is then cut to the desired length.

Corrugated Roof Sheet
Corrugated roof sheet is also called roof sheet. It uses colored coated steel sheet, galvanized steel sheet and other metal plates to roll and cold bend into various wave profiled boards.It has the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake resistance, fire prevention, rain proof, long service life and maintenance free.It has been widely popularized and applied.
