Anti-climb is a mesh decision before it is a height decision. A standard diamond aperture gives a climber toe holds; a tighter aperture removes them. On a street frontage that is worth more than another 600 millimetres of height, and it does not change how the yard reads from the road. Height still matters, but a tall fence with a standard aperture and a slack run is easier to defeat than a shorter one specified properly.
Most yard entries happen underneath. Slack mesh can be lifted and crawled under, which is how a great many display-yard entries actually occur — not over the top, where the cameras are pointed. Correct tension, checked rather than assumed, plus a bottom rail or a ground-fixed base on runs where lift-under is a real risk, closes it. That detail belongs on the quote by name.
The fence must not cost you the coverage you already paid for. Existing CCTV is usually positioned for the yard as it is. A new line, and particularly a new gate frame, can cut across a camera's field of view. Chain wire's transparency means coverage generally survives it, but where posts and gate frames land still matters — and moving them is free at set-out and expensive afterwards.
Toppings belong where nobody is looking. Barbed wire on a rear or side boundary is unremarkable. On a customer-facing frontage it reads badly and adds a liability question you did not need. Where a frontage needs more than mesh and height, the answer is usually aperture, tension and gate hardware rather than a topping — and if a topping is genuinely warranted, whether it is appropriate on your boundary is a question for your council and your insurer rather than your fencer.
Appearance is part of the specification on a main road. A fence on an arterial is seen by a lot of people every day, and a rusty, sagging line says something about the business behind it. Black PVC-coated mesh with matched posts is the usual specification on a customer-facing boundary: it reads as a deliberate part of the site, holds its appearance for years, and lets the stock be the thing people look at. Galvanised does the same structural job for less on the rear and side runs nobody sees. AS 2423-2002, 'Coated steel wire fencing products for terrestrial, aquatic and general use', covers chain-link fabric together with its zinc, zinc/aluminium-alloy and plastic coatings.
