A typical wooden garden shed having wooden slats or a thin metal garden shed is not a bear proof structure.
If black bears can get their claws under or in between wooden slats they can then tear that wood off the structure. And we have seen numerous metal garden shed doors easily crumpled by a bear trying to gain access to a garbage bin stored in a metal shed.
Pictured above is a DIY version of a bear proof container using metal flashings around a solid wood construction with metal crossbars to latch the doors: any gaps should be less than 3/8". See the document below for more ideas on making an enclosure bear resistant.
