I am comfortable with using ext grade plywood for decks and floor. I've used it on other projects and very happy with results. I could handle doing sheet aluminum, but only with standard fastners, since I don't have the welding equipment or tallent. I am not concerned about wood rot. Primarily interested in calculating the amount of weight savings if going through the extra work (for me) of going to sheet aluminum. I couldn't find any info on minimum aluminum thickness for span length recommendations. My floor spans are 14" on center, and would like similiar span for casting decks. Does anyone have what the minimum and/or recommended sheet aluminum that should be used? and its corresponding square foot weight? If there is a specific thread on that here, a link would be much appreciated.
Note: Support framing would primarily be aluminum.
Also: Floor covering will not be carpet. Some form of paint, possibly bedliner type will be used.
