Most safes contain three primary layers of protective metal: 1  The outer mild steel skin. 2  A hard plate barrier material to protect the lock. 3  A mild steel layer to which the lock is affixed.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.
