Three types of vault were commonly used: the barrel-vault, the groined or four-part vault, and the dome. The barrel-vault was generally semi-cylindrical in section, and was used to cover corridors and oblong halls, like the temple-cellas, or was bent around a curve, as in amphitheatre passages.
Mercantile safes must be equipped with at least one combination-lock, and be fire and burglar resistive. The doors are made of steel (at least 1â³ thick) and the box is also made of steel (at least 1/2â³ thick).Banks and other institutions allow customers to deposit money after hours through night safes.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.
