To "strike a deal" is an idiom, and its meaning is only tangential to that of the much larger and broader term to establish.
Moreover, it's probably more common to talk about "making a deal" rather than "striking" one. And I have never actually heard anyone talk about "establishing" a deal; it would not be impossible to do that, but it would point in another direction, away from the common meaning you're looking for.
