Generally the domestic pipes are in galvanized iron, or in mild steel, materials with a good relationship between quality and price.
However, the use of synthetic pipes for plumbing and copper pipes for gas and heating is becoming increasingly common.
Copper and synthetic materials, in fact, have excellent characteristics of strength, practicality and ease of processing. The traditional galvanized iron pipe, however, continues to offer undeniable advantages due to its strength, ease of connection and low cost.
Attention must be paid because hygienic standards suggest the use of synthetic or metallic pipes, provided they are specially treated for home-food use.
