source for .020 inch sheet steel ?

[fairchild]

Have been hunting for 25 ga. sheet steel to fab up some rudder ribs---
No one seems to have that thickness--- does not have to be 4130---
Just cant find any sources------
Has anyone used any lately and remember where it came from ?
(have not tried metric sources yet---)

I just used 22ga mild steel. Got it at a local steel supplier.
