What materials are best for a Medium Sized Safe?

When choosing materials for a Medium Sized Safe, focus on the steel used for the cabinet/door panels, and then pay attention to the internal accessories. The choice should be based on your specific needs.
Cold-rolled steel is the mainstream material. A door panel thickness of 8-12mm and a cabinet thickness of 4-6mm are recommended, with increased pry resistance with increasing thickness. Avoid hot-rolled steel, as it is prone to deformation and offers poor theft protection.
High-end models use alloy steel (with added manganese and chromium), which is harder and more impact-resistant, suitable for valuables, but it is 20%-30% more expensive than cold-rolled steel. If your budget is limited, cold-rolled steel is sufficient.
Internal accessories: Choose thickened steel plates for shelves (good load-bearing capacity) or environmentally friendly ABS plastic (lightweight); choose stainless steel around the locks to prevent rust from affecting unlocking.
Suitable scenarios: For home use, choose cold-rolled steel with stainless steel accessories for documents and jewelry; for commercial use, prioritize alloy steel for documents and cash. Regardless of the type of Medium Sized Safe chosen, always check the welds at the steel joints for strength; the smaller the gaps, the harder it is to pry.
