The solution to this inquiry might be summary. It might rely on what are the individual's definition of security is. It would also depend upon what see your face is trying to secure. In the case of padlocks, generally speaking, the greater the cost the higher the security.
high security padlocks
First thing we are going to look at may be the construction of a padlock. What material is a specific padlock crafted from? Is it steel, brass, aluminum or hardened steel, the material the padlock is made away from contributes straight to the safety. The dimensions of the padlock also directly concerns the physical security. Let us take laminated padlocks as an example, they supply very good physical security. They do this by layering one steel plate over the other. This process supplies many different sizes.
The sort of lock cylinder that is utilized also directly concerns security and price. It is important to keep in mind that the type of lock cylinder and hence key, is probably the most critical components. For example, you wouldn't want probably the most physically secure lock having a lock cylinder that does not have key control. As I wrote before, key control is just about the important security item associated with a lock. The padlock shackle is exactly what provides the most physical attacks. So the length, diameter and materials used are very important. You can find padlocks made that do not have visible shackles.
