    Try a search for metal dealers in your area, or yellow pages. Check with welding and fabrication shops for their suppliers.

    it looks like a 4x8 sheet of .25 weighs about 113#. 3/4" ply is about 75#. Also, I can't imagine what the aluminum would cost, but even at $2 a pound it would be quite expensive. Cheap small boat hulls are really thin like .068 and the nicer ones .100 and .125.

    Wow you would think a 4x8 sheet of aluminum would out weigh 3/4 marine board .

    I actually only need 1/4 inch for the flooring and maybe 1/8 or possibly 1/16 for the rest which would just be cosmetic anyway to hide wires and such .

    I can get diamond plate (aluminum) in 4x8 sheets for $99 in St.Louis and thats the best deal I have found so far .

    For the record, there is no need for 3/4" plywood in a boat for a floor.
    It's not a house nor does it have the same live load or dead load a house would require.

    I use 1/4 and 1/2 for all my flooring needs. A little bit of epoxy and glass goes a helluva long ways. I build canoes and kayaks out of 3/16" that are capable of handling a 1/4 ton load.
    Weight will depend on what species of plywood you use. I mean you can spring for Okoume 1088 marine plywood which is 40 pounds a sheet for 1/2" or A Meranti 1088 at 50 pounds a sheet.
    I don't have the weight of an onshore fir marine plywood but it's going to weigh more then those. Somewhere in the 70's would be my guess based on having worked with it.

    And then you have other options that aren't in the metal or wood realm. True, the sticker price seems high but in the end when it's all said and done the price difference between all of them is going to be in the same ball park installed as they should be.

    I think if you can get 4x8 sheets of diamond plate you better buy a truckload of it @100.00 /sheet. The last time I checked that stuff ran about 65.00 for a 2'x3' hunk .065

    I am still trying to figure out why you think you need 1/4" for the floor. My floor in my jonboat is made of old street signs. It flexes a little between the ribs, but in several years has yet to break (and i weigh 250 on a good day). I would think 1/8" would be more than enough.

    If I were set on having aluminum flooring....I would check with these guys about the perforated sheets if you are wanting to save weight.....

    I have seen boats with it, but have not used it personally...FYI
