The shop in question is “ANP Metals” fencing supplier, located at 481-483 Grand Jct Rd, South Australia (Way: 493815547 | OpenStreetMap).
The business specifically focuses on creating fences and enclosures (https://www.anpmetals.com.au/fence-supplies-adelaide/), however shop=fencing
does not seem to be widely used (overpass turbo). I can’t find a lot of information on the topic, and I’m not sure which option to pick:
shop=trade
,trade=metal
,craft=fence_maker
shop=fencing
Additionally, shop=fencing
causes miniscule ambiguity with ‘fencing supplies’ in the context of the sport, but that’s a matter for a different forum thread.
