It's sturdy, heavy enough gauge metal, and appears to be durable.  Not to say there were not frustrations... most of corners were bent, making parts difficult to align and once bent back into place with pliers a little dented looking - but only on the bottom corners.  If we paid more than we did, we would've been upset and given a bad review.  It would've been nice if they made this clear, that parts were bent up, but since we got this for maybe half what it could be worth (if the parts were all in pristine condition and unbent), it's okay.  If you're prepared to do a little DIY, this box is great and decent value.  We'd buy it again - but this wasn't one of our best Wayfair purchases.
