One of the primary advantages of tin lunch boxes is their durability. Unlike plastic alternatives, tin boxes are capable of withstanding significant wear and tear, making them ideal for daily use. They do not break, and their sturdy construction ensures that the contents remain intact during transportation. Additionally, tin is an excellent material for preserving food quality, as it is non-toxic and does not leach harmful chemicals into food, a concern often associated with plastics.

Galvanization involves coating iron or steel with zinc to prevent rusting. While this treatment extends the life of pipes, it also alters their surface texture. The roughness created by the galvanization process can increase the friction factor compared to smooth-walled pipes. This increase implies greater energy requirements for pumping fluids through galvanized pipes, particularly in systems that rely on water or other low-viscosity fluids.
