Very true, Vicegrip. The material you are refering to is Alucobond and they are one of our competitiors. Pretty much the same product with the main difference being the paint method and paint system.
This material is everywhere and you just don't know it. It is big in the sign industry but it is even biger in the architectural arena - the building designers love it because it can be routed in the shop, shipped flat and then assembled on the jobsite. Not to mention, it is as maintenance free as you can get. It is used frequently on gas station canopies and the exteriors of buildings. All of the major oil companies have run programs with Alpolic - Mobile, Citgo, BP, Shell, Amoco, etc. Dairy Queen, 7-11 and Honda also have spec'd Alpolic for their structures. Alpolic carries a 20 year warranty on the paint for color hold out and gloss. Take that, Alucobond!
