However, there are scenarios where a rougher surface may be beneficial. In construction applications, for example, a rougher galvanized surface can provide improved bonding with paints and other coatings, ensuring durability and protection against corrosion over time. Moreover, in certain industrial applications, increased roughness can enhance mechanical properties such as resistance to wear and tear.

Different applications necessitate different thicknesses of corrugated steel sheets. For roofing applications, sheets must be engineered to withstand various environmental factors, including wind, rain, and snow. Generally, a thickness of at least 0.5 mm (approximately 26 gauge) is recommended for residential roofing to ensure durability and longevity. In commercial settings, thicker sheets (0.7 mm or 24 gauge and above) may be favored for added strength and resistance against heavy loads.
