Our panels are not designed specifically for trucks going on the tracks, or vehicles that only see daylight every now and then. We built them as a complete alternative replacement for OEM or other steel aftermarket panels. Which means they need to stand up to extreme temperatures, hard work, and all terrains. Our panels have a thickness of 1/8th inch with a weight to match OEM Steel, with the same material used in semi-truck day cabs. Our products are built to handle the coldest temps, toughest terrain, and hardest jobs. This is why all EGP® products have 30 day return after delivery, and a 3-year warranty!
