I used sheet aluminum... I procured a large amount of used road signs and some sign vinyl from a D.O.T. shop.

However, if you really want, scrap yards will sell you old road signs for the price of scrap aluminum, very cheap compared to going to a supply house and buying aluminum sheets.

The exposed wood I painted with 5 coats of Dutch Boy deck/floor sealer.
