[QUOTE="LonLB, post: 186833, member: 4391"] C channel. That way you can use the bottom flat section to bolt the tubes to, and the top to bolt the deck too. And it's what pontoon builders use. 3/16" thick, and approximately 3" tall. That is what we used at Bennington. However that was done because of the BIG engines used, and they could cause flexing of the floor. So I would find some happy medium between thinner and shorter than the above. FWIW the height adds as much or more strength than thickness. When we switched we stayed at the same thickness, but went to a taller C channel. [/QUOTE]
