Hey, totally get where you’re coming from — balancing security with aesthetics is trickier than people think. I used to manage a warehousing site in Parramatta, and we went through a similar decision process a couple of years ago. Ended up going with chainwire fencing with barbed wire topping, but only around the back and sides. The front had powder-coated mesh panels, which looked a lot neater and gave us a professional front without compromising security too much. Another big factor is council regulations and site access points — those can affect what’s allowed or practical.
If you’re still researching options, I’d check out LS Fencing Services — we found them super helpful, especially when it came to understanding what’s standard vs. what can be customised. They’ve got a decent breakdown of commercial security fencing Sydney, and they helped us tailor things without just upselling. Ask about integrating sliding gates or even automation early — trust me, doing that after install is a nightmare!
