Thread: Gun cabinet - questions

So, finally my FAL application is in (now that I've finally finished building the "shed") during which time I've acquired a home made gun safe, which has been fabricated out of 6mm plate, with external welded on very heavy duty "hinges".

I have a couple of questions for the collective wisdom. Reading through the "safe storage" requirements it says steel cabinets should be 3mm minimum but if they are less than 3mm the door should have internal bracing to stop it being bent or deformed....given that my cabinet is 6mm...do I still need this bracing? The guide is somewhat open to interpretation!

Second Q, the guide also states that hinges should be internal or protected, given that my external hinges are welded on and the smallest dimension of there format is 7mm...what do I protect them with?
Also, cabinet door is secured by one high security padlock that passes through the wall and door of cabinet at the top right corner, is this sufficient or should I add another padlock at the bottom corner?
My aim is to ensure that a: my cabinet will pass inspection and b: make my firearms as secure as possible.
Cheers in advance for your input 👍🏻
