Grille and Padlock are the most common combination used at the front or back door. From our experience, we found out the following:
Welded padlock bracket is actually not that strong
Why do we say so? Our technician learned some welding before, and we have also cooperated with plenty of grille welder, both stainless steel and steel. The process of welding itself actually melts some of the metal body in order to create bonding. Thus the welded part is a thinner part. (thinner metal cannot be welded due to this; welding will instead make holes to the thin metal sheet).
Frankly we are not welding specialist. There might be someone or some other welding methods out there that do not melt and make the metal become thinner. But from experience we’ve seen a huge number of padlock break-in cases in Kuching that happens just like this case:
Very frequent happened. Padlock was not attacked. Instead thief attacked the bracket. In all cases, the broken part is randomly bent. Means the thief us forcing the bracket to move left-right-left-right till it breaks. And it breaks at the welded part.
Not one case, not two cases, but plenty. Welded bracket is simply a weak point at the grille.
Our suggestion? Use a full body wrap bracket. Or use a thru-fixing bracket. So much stronger, and so many times harder to break. Below is an example of thru-fixing bracket, which is also our locksmith’s favourite:
In the above cases, we use Hardened Steel (Steel and Stainless Steel are saw-able, Hardened is not saw-able) Bracket. The screws are non removable, and there are no welded part. So in order to defeat the bracket, you need to rip the whole metal grille body apart. This is really tough to do.
Now, what type of bracket are you using?
