I tend to agree with Dennis. There is another aluminum vs steel thread that I posted on earlier today. I have been in the aluminum extrusion business for 20 years and know a little about it . The steel wall pools are "1 piece" , where the aluminum are several individual self mating pieces. If something happened to that die while the extrusion was being run like, if it broke where the extrusions snap fits together and it wasn't caught before being painted it could very well weaken the whole structure significantly and all it would take is one bad extrusion to make a huge mess out of your yard. Even though this senario is very unlikely I have seen many scary things with extrusions before. Our main business is architectual shapes, curtainwall and store front shapes, which is the same alloy that pool walls are....6063. We have looked at the pool wall business but decided not to pursue it. It's not really "gravy" material even though we could do it. I have a 24' AG steel pool and it is 5 years old now. I replaced the liner for this season and the walls are in perfect shape.

I have been running my pool following the instructions of this website and for the last 4 years I have had perfect water throughout each swimming season, while my neighbors running baquastuff have fought algae each year. They must have deeper pockets than me. My pool has been a joy to maintain following the simple rules and advice of the wonderful people who has figured it out..Thanks to Ben and all the other who have contributed. I wouldn't have nearly as beautiful water as I do if it wasn't for poolsolutions!!
