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.

One of the primary determinants of the friction factor is the roughness of the inner surface of the pipe. Galvanized iron pipes often exhibit a relatively high level of roughness compared to other materials, such as PVC or copper. This rough surface can lead to increased turbulence in the fluid flow, resulting in a higher friction factor. Suppliers need to pay close attention to the manufacturing processes that can influence the surface finish of their pipes. Techniques such as improved galvanization methods or surface treatments could significantly reduce the internal roughness and thereby lower the friction factor.
