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.
