what kind of steel are safes made of
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.
