The storage shelf was delivered to my house in a very sturdy package. The package included a pair of glove that was very helpful during the shelf installation. The shelf was made from aluminum and unpainted so the "white" color description is not correct. It should listed as "aluminum silver." I love the design of the support  brackets that make the height adjustment of the shelves  a lot easier. the support posts are made of thin aluminum sheets so this shelf should be used as "light duty shelf." It's is perfect for what I need for my storage shed but I have to nail it to the wall to keep from falling if the load is not balance. Anyway, I give it four stars and highly recommend for light duty use.
