Material comparison can be conducted based on the needs and requirements of the clients who need the safe. A material based comparison could be done, and it is also possible to do a comparative study based on the resistance against an active burglar attempt, environmental issues and more.The raw materials that are used in safe construction would vary based on time and the current needs. In the past, safe construction was mostly done with steel doors. However, then, as the security of these safe construction, came under scrutiny because of the breach in the form of cutting of doors with acetylene torches, and it was necessary to use cast iron with concrete or other materials. Minimum reinforcement concrete, hearth steel, and steel are some materials used, and in specific steel of different forms is the most used for bank vault and safes. For instance, “Body walls of material equivalent to at least 1″ open hearth steel with a minimum tensile strength of 50,000 P.S.
I” is the description of one of the material used as per the required burglary defence classification. These classifications will lead to the selection of specific tensile strength and ultimately the final work is formed. Underwriter Laboratories standard if often used worldwide, so different forms of steel classified into different class strengths by UL standards can be applied based on the need. In the concrete reinforced steel materials, the safe walls and doors are mainly made of concrete. This was probably the only form of safe or vault construction in the past. This form of construction is cheaper, uses traditional construction materials and can hence be achieved at a much lower cost. Now this form of material used in construction was challenged because of strength. Strength issues arise because unlike a normal construction, a safe construction is expected to be more long lasting and versatile.
