These are a very flexible option for installed shelves. They are actual pipes! We bought longer pieces of pipe to make taller shelves. Not sure if plumbing pipes would have been cheaper since you also have to buy the shelves separately. But it suits our needs to a tee and look great. Very sturdy when attached to wall studs or ceiling cross beams.
