In contrast, the safe box of the semi-steel safe is a relatively thin steel plate wrapped into a box shape, and then safety box manufacturer filled with a mixture of cement, sand, gravel, etc. The cost is much lower; safety performance, Naturally, is also low, and falling from a height may cause the cabinet to crack.
