Now that aeroplanes no longer land within inches of bedroom windows, cars probably constitute the greatest source of noise in Hong Kong. Hence the importance of noise barriers, particularly where people are living cheek by jowl with transport. At Wong Chu Road, engineer Scott Wilson Kirkpatrick designed an enclosure using 2,400 tonnes of steel made up from a variety of sections. Jotun Coatings came up with a way of protecting the steelwork from corrosion and fire that didn't involve on-site coating.
It arranged for all coating to be done in the UK. Intublast Protective Coatings applied Jotun's Barrier zinc-rich epoxy primer, followed by Steeelmaster 60 intumescent coating, and finished it with Steelmaster Top Sealer. The steel was shipped in containers to Hong Kong. Only 2 per cent need any repair to the coating after erection.
