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.

In addition to cost-effectiveness, fillers can improve the mechanical properties of plastics. For instance, the addition of glass fibers or carbon black can enhance the tensile strength, impact resistance, and stiffness of polymer composites. This makes fillered plastics suitable for a wide range of applications, from automotive components to electronic housings. In particular, glass fiber-reinforced plastics (GFRP) are increasingly used in lightweight construction, as they combine low weight with high mechanical strength, thus offering improved fuel efficiency in transportation.
