Well, there are several levels to that question. First, we guarantee that the product shows up at your door in perfect condition. We hate it when things that we spend our hard earned money on show up like they've been dropped from a plane. If your guards arrive damaged, please contact us immediately at help@rockfacegear.com or use this form. We will ask to see a photo of the damage before mailing replacements. They're made of steel and have a powder coat finish (not paint!), so they should hold up to typical off-highway driving. Slamming into a concrete block is a whole different story.
