Advantages of Galvanized Corrugated Sheet

1. High Toughness

Galvanized corrugated sheet combines steel strength with corrugated design, which makes it high in strength to withstand extreme weather, like heavy snow, wind, etc. Thickness will greatly influence the strength and durablity. Generally, the common thickness for roofing is 0.4- 0.6 mm. You can choose according to the location weather condicition and your use purpose.

What Is Galvanized Corrugated Sheet?

Galvanized corrugated sheet is also known as corrugated galvanized iron sheet, abbreviated CGI sheet or GI corrugated sheet. It is a building material, which combines steel and zinc coating, which makes it corrosion resistant. The corrugations increase the bending strength of the sheet, which is profiled using the process of roll forming. Through different rolling dies, it will form different corrugations. After the steel sheet passes through the rollers, it will be sheared off at a desired length. Below is a video of profiling process of color corrugated steel sheet for your reference.

Wanzhi Steel has different rollers to profile different corrugations to meet your requirements. Also, we have a special quality inspection department. All products will be inspected before delivery. You can find more videos on our YouTube. Also, you can come to visit our factory on-site.
