Janni Lipka volleyed the Steelmen into a 24th minute lead with Matt Griffin acrobatically adding the second five minutes later.

Phil Reynolds curled in a fine 22-yard effort to restore parity just before the hour mark.
With the game finely balanced it was Parkgate that grabbed the decisive goal on 73 minutes with the help of some sloppy defending that allowed Nathan Swindells a run in on goal where the striker held his nerve to guide a low shot past Martin Taylor and inside the far post.
The Steelmen had to play out the last 10 minutes with ten-men after full-back Daniel Cardwell was sent-off for a second yellow card.
