I have always read that any type of sump or tank of a respectable size should be made out of cast. Is there any reason that I couldn't make the following prop tray out of extruded?

Dimensions: 48"x36"x12"H -

Thanks

for flat sheet I always use cast.. I don't think there is to much of a savings in sheet using extruded but I am not sure as I have never priced extruded sheet.
