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.

2. Lightweight Construction Compared to traditional roofing materials, such as tiles or concrete, trapezoidal sheet metal is considerably lighter. This characteristic reduces the load on a building's structure, making it easier to install without requiring extensive reinforcement. Consequently, this can lead to lower construction costs and faster project completion times.
