3/16" thick sheet metal curved

This came off from a big tank. Total weight is around 4500# There are 9 sheets total. 3 are 69" wide x 10 feet long. 6 are 80" x 10 foot. 1st picture shows what they look like on the inside part. Outside surface is in good condition also. There are a couple holes where there were pipe bungs that I cut out. All are in good condition and very suitable for use except 1 has alittle rust pitting (part that was inside tank) It is the top piece with the bent corner shown in the pics. All sheets are curved. Would work good for a cattle tub as there were curved. (tank was like 10-12 dia.) or be flatted for a trailer deck etc. I have the ends which are flat 3/16" thick also if interested in those.
