Product review (4 stars): Yep, it's stainless steel.
This is a nice product for a great price from the seller I purchased from. The biggest issue I've experienced is the same as others: sellers package this in flat cardboard and the ends are absolutely going to be bent. This is going to most likely be your experience, too. I knew this going in and expected that I would need to pound the edges flat with a rubber mallet. If you're like me, you're going to purchase this anyways. Just make sure you have a rubber mallet.
