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.

One of the key benefits of galvanized iron square pipes is their durability. The zinc coating acts as a sacrificial barrier; even if the surface is scratched or damaged, the underlying iron will still remain protected. This characteristic is especially vital in construction projects where pipes are exposed to harsh weather conditions or corrosive substances. By choosing galvanized iron square pipes, builders and manufacturers can reduce maintenance costs and replace pipes less frequently, leading to more economical and sustainable practices.

2. Manufacturing and Transportation Costs The processes involved in manufacturing concrete and steel can be energy-intensive, contributing to the overall cost. Moreover, transportation costs, which have risen due to fuel price fluctuations, also affect the prices of these materials, as moving heavy goods over long distances can become expensive.
