Well turns out louver's in aluminum is a pain in my a**. Not mater what I do the aluminum splits at the corners. I even tried to aneal the aluminum half way, it helped but still split. So here is an example of what I can do with the aluminum. The dimple dies and bead and step rolls work really good. I can also cut slots or drill holes with no problems. here is one I whipped up tonight.
it is super light too!
and here is a little sample piece of aluminum beside a steel louvered one.
thanks again all
