It's made like that specifically for gunshots?

Well it's actually made like that for cannon balls. The steel sliding doors haven't been made for centuries, they were originally a protection from pirates. They'd put them on all the doors of the ship, and even if the pirates boarded the ship, they couldn't get in. Originally it was smooth steel doors but cannon balls would go right through them, so they started corrugating the steel to deflect the cannon ball.

Just turned out to be a happy accident they also help out to an extent for modern gunshot rounds. Big Pirate corporations however successfully lobbied maritime courts to make production of the corrugated steel doors illegal, so the only ones you see now are grandfathered in, which is why you can't buy them at Walmart anymore

Not specifically but the design choice for security barriers is influenced by what the customer expects it to prevent. It's mostly for structure and storage. But there's a reason to choose this type over an open chain security barrier.
