Narrative:

We (2) a&P's work for air carrier. We were sent from ZZZ to WWW to fix a right engine problem. We accomplished a high power run and were returning (taxiing) to our parking spot. We were not familiar with the airport so we had lots of help from the tower. When we entered the parking area we noticed that there were no taxi lines to follow. We spotted our guide man several hundred yards ahead. He indicated where we should park by pointing his wands to a park line. We saw the end of the park line and headed for it. We were just about to turn on the line when our left wingtip hit a blast fence. We immediately stopped and shut down. We called for a tug. The fire department and airport authority/authorized showed up and took over removing the airplane from the fence. There was no fuel leakage, or fire danger. The wingtip was completely severed at the point where it attaches to the wing. We later found out that this is a deicing area and overnight parking. They do not normally taxi aircraft to this area. They tow them.
