How Do We Make Corrugated Steel Sheets?

Galvanized corrugated sheet is a metal sheet that combines strength and corrosion resistance, with its core advantage being the perfect combination of galvanized layer and corrugated structure. The sheet is made of high-strength cold-rolled steel plate as the substrate, and a uniform and dense zinc layer is formed on the surface through galvanizing process, with a thickness usually between 0.12-2.0mm. The weight of the zinc layer can be selected from 60g/m ² to 275g/m ² according to the needs, which can effectively resist the erosion of atmosphere, rainwater and various corrosive media, greatly extending the service life. ​ The corrugated shape endows the board with unique mechanical properties. Common waveforms include V-shaped, U-shaped, and trapezoidal, with wave heights ranging from 5mm to 75mm. By dispersing stress through a wavy structure, the load-bearing capacity of the board is increased by more than 30% compared to a flat plate at the same thickness. The surface of the board is smooth and flat, presenting a uniform silver gray metallic texture. Some products can also be color coated, combining decoration and functionality. In addition, galvanized corrugated sheet has good processability and can be cut, bent, punched and processed according to actual needs, meeting diverse installation requirements.
