Good thing it’s painted with our International coatings. Facts and figures 503 meters long 6,000,000 rivets 180,000 vehicles use it daily 10,000m2 of steel coated with our International products Affectionately known as the Coathanger, the bridge features our Interzinc, Intergard and Interthane products. More about International Painting the world’s biggest coathanger Sydney Harbour Bridge is one of the world’s most recognizable landmarks. Spanning 503 meters, it took nearly nine years to build and features 52,800 tons of steel. Back in the year 2000 – shortly after it was the centerpiece for the city’s spectacular millennium fireworks – the organization in charge of the bridge decided that it needed a fresh coat of paint. But not any paint. The existing coating was based on old technology and was in urgent need of an upgrade. What the bridge really needed was a high performance coating that not only looked good, but could also offer rugged corrosion resistance. This would help to maximize the time interval between recoats and provide long-term aesthetic durability, while remaining cost-effective. Coatings expertise And it was AkzoNobel that provided the necessary expertise when the bridge (affectionately known as the Coathanger) was painted in 2003. The company supplied an International coatings system made up of Interzinc (a zinc-rich epoxy primer), Intergard (a high build, high solids intermediate coat) and Interthane, a polyurethane topcoat. Corrosion resistant The system – which was applied to 10,000m² of steel – proved more durable and corrosion resistant than the previous coatings and was far more environmentally friendly, with only 25 percent of the level of VOC emissions. So if you should find yourself on the bridge one day, you might want to take a closer look.
