(Kung Fu) Jin Gang Iron Palms

From the movie Invencible Shaolin (1978) directed by Chang Cheh and the actor is Lu Feng.
I'd like to know what Kung Fu style is this, because although I've made some research, I'm not yet sure if it's the style written on the title.
So if anyone could tell me I would really apreciate it.

The style with the use of hands is a form of iron palm or could be sand palm technique. The use of the pole is the light skill technique. I am not sure of the leg technique.
