To ensure that a vault is safe, it must be inaccessible from every direction i.e. walls, floors and roof slabs. Godrej Tang Bars, when used in construction, reinforce the vault room against attacks from any direction. Tang Bars are made of MS sheets. The strips are punched to form a double combed structure. The long strip is twisted before it is laid in the wall, floor or roof. They are used to reinforce the high security vaults.
