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.

Once the materials are prepared, they undergo a meticulous extrusion process where they are shaped into sheets of various thicknesses and sizes. Cutting-edge machinery allows for precise measurements, ensuring that the slip sheets are custom-fit for different roofing applications. After shaping, the sheets are subjected to rigorous quality control tests, checking for durability, flexibility, and the ability to withstand environmental stresses.
