We put some fans out on our patio. Over a few years, the blades have
drooped. These blades appear to be some type of luan, about 3/16" wide.
They appear to be either composite plastic, or some form of pulped wood.

Can they be straightened? Maybe put in an oven with some brick weights,
and a pan of water to make a steam chamber out of it? Other suggestions?

If I go buy new ones, are there different materials and grades? The local
ReStore, (the one for Habitat for Humanity) has sets of 5 for $3, and I'll
take them Wednesday when I go to see if the bolt pattern is the same. But
just wondering if these can be salvaged.

For use in an uncontrolled atmosphere like a patio get a set of blades
designed for outdoor use.
Anything else will be a waste.
