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.

The food and beverage industry heavily relies on printed tinplate sheets for packaging products. Cans made from tinplate are ubiquitous, housing everything from soft drinks and beers to canned fruits and vegetables. The prints not only identify the product but also create a visual appeal that can influence consumer choices. Eye-catching designs and vibrant colors can attract attention on store shelves, thereby enhancing brand recognition and loyalty.
I costi per i tetti in metallo nel 2014 variavano a seconda del tipo di materiale e della tecnologia di produzione utilizzata. Ad esempio, i tetti in lamiera zincata erano generalmente pi economici rispetto ad altre opzioni come quelli in alluminio o rame. Le cifre indicavano che i prezzi oscillavano tra i 20 e i 50 dollari al metro quadrato, a seconda della complessit del design e delle finiture richieste. I produttori cinesi, grazie alla loro efficienza produttiva e ai costi di manodopera relativamente bassi, riuscivano a mantenere prezzi accessibili pur garantendo un buon livello qualitativo.
