Question Solar reflector material types?

Greetings from Rough & Ready, Ca.
I am wanting to build some double involute solar reflectors to go behind a 6" stainless tank, 10' long... (stainless steel exhaust pipe; don't ask me what it cost!)
If you're not familair with 'double involute', it's a reflector desiged to concentrate the sun's rays to the centered tank, no matter where the sun is.
Figuring the geometry for the involute is not my problem. What I need is some mirror-like metal/plastic sheeting thin enough to curve, yet thick enough to 'hold it's own' weight. It will be supported by the edges only.
I need four panels about 3'+ x 5'+.
Do they make a mirror reflective Mylar, mirror polished stainless (I'm sure cost prohibitive)?
I hope you guys see what I'm a tryin' to do.... I was even thinking of using some heavy costruction paper/cardboard, and trying to 'line' it with tinfoil. I'm sure that there's something more durable out there...
Thank you much...
