Outokumpu bridge project

Outokumpu Stainless Hot Rolled Plate has received an order from Hong Kong for stainless steel to be used in the construction of a bridge. The order is for a total of 2000 tons of stainless steel individually hot rolled plate. The stainless steel will be used in the production of the Stonecutters Bridge in Hong Kong, to clad its two pole towers, or pylons, with a special stainless steel skin. The pylons will reach a height of 300 metres, and the use of a stainless steel skin for the top 120 metres is designed to improve their strength and stability. Upon completion, the bridge will be one of the longest single-span cable-stayed bridges in the world, with a span of around one kilometres. The order will be produced at Outokumpu’s facilities in Degerfors, Sweden, and is estimated to be worth around SEK 90 million. “The stainless steel plates will be delivered with a special surface finish. The high quality surface finish will improve corrosion resistance and enhance the aesthetic appeal of the structure,â€? says Anders Finnås, the man responsible for developing new applications for the Hot Rolled Plate business. Following tests by Ove Arup & Partners and Anconin the UK, a duplex grade was chosen for its combination of high strength and corrosion resistance. The bridge will need to be able to withstand very harsh environmental conditions, including high atmospheric humidity with high salinity and a severe climate, with high winds that often reach hurricane force.
