From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or door) secured by a lock.ault Walls: They are made of a mid-layer of strong material sandwiched by two layers of mild steel. In some vaults, glass panels are inserted to trigger relockers if they brake. Vault Doors: They are heavy doors (many tons) formed by many layers of steel and other barrier materials optimized to resist forced entry.
In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determine the properties of each steel grade. The carbon content in steel can range from 0.1-1.5%, but the most widely used grades of steel contain only 0.1-0.25% carbon. 1  Elements such as manganese, phosphorus, and sulfur are found in all grades of steel, but, whereas manganese provides beneficial effects, phosphorus and sulfur are deleterious to steel's strength and durability.
