Why do you use stainless steel instead of plywood or particle board to make cabinets?

We have a wet kitchen concept; 

People tend to use a lot of water and liquids to clean their kitchens. 

Plywood, particle Boards (third generation wood) and the fronts made of medium density fibreboard (MDF) gets soggy and degenerates in short period of times. Whereas, steel modules last forever; water or liquids of any kind never affect steel.

The need of the hour was to innovate and invent ready to assemble stainless steel cabinet modules.
