Smooth or embossed

This particular panel has a smooth finish, and it's non-embossed, so this would be your typical clean room, and if a customer really prefer to have a smooth surface. A lot of places, they opt to go into the embossed finish, which is on this side, and it's a 26 gauge. When we do go to the smooth finish, we highly recommend going to a heavier gauge because of the oil canning. The oil canning is any undulations in the foam that's foamed in place in the manufacturing segment of the panel, so it kind of washes out that undulation and the panel finish.

When you buy a flat, smooth panel, they will do a QA on it to make sure that it meets the industry standards, but if there is an undulation in it, that's acceptable to some point because that's a smooth, flat surface. One of the reasons they do a shadow line profile on the panel is you take those undulations out in the sheet, and you also, with the embossing, you can't see that if you look across the face of the panel.
