I bought the stainless steel box so I shouldn't need to worry about paint or corrosion.

I'm quite disappointed with the quality of construction.
Many of the edges are sharp and it cut my hand when trying to retrieve the keys from inside the locked box.
some of the spot welds are also unfinished and have sharp points.
The lock was installed upside down also.

I spent a nearly one hour filing all the edges to make it safe.

I would like a better lock. If it is placed on a rough surface (stone wall), it requires careful installation because otherwise it becomes crooked and the door does not close.

Very good choice.
Well-designed, ergonomic, high-quality construction, seems to be durable over time.
I would easily recommend it to a friend.

Perfect! Made of galvanized steel with anti-corrosion - electrostatic paint, includes screws and a lock with 2 keys. Spacious enough to fit a larger folder, magazines, and newspapers. Weather-resistant as it claims (time will tell) and a Greek product.
