In public buildings, more intensive uses of the elements that compose them are foreseen, so that the hardness and durability of materials to be used must be greater than for particular uses.
And the accessories that compose them are not those for private use: push-pull hinges, anti-hook handles, aluminum sockets, aerators, anti-pillars, etc. In addition, the legislation requires different certifications for doors, windows, sectorizations, etc. and distinctions are made between schools, nurseries, institutes, clinics and hospitals.
Whether they are Melamines (with resins that reinforce their hardness) or HPL (High Pressure Laminate) the works for this type of projects are always tailored to the architect or the designer, so the color range has to be very wide.
