4off tower saddle casting asembles for the Hardanger suspension bridge in Norway.
EN 1.6982 GX3CrNi13/4 alloy steel, 26,000Kg, finish machined, fabricated & assembled
4off splay saddles which anchor the cables into the bed rock at each end of the bridge. The 13Cr 4Ni alloy castings were welded to the carbon steel fabrication with the welded joint incorporating a nickel alloy 625 intermediate layer.
EN 10340 G20Mn5 low alloy steel, 289Kg - 1,130Kg, finish machined & painted
Over 350 cable clamp bands were manufactured for the Hardanger Bridge.
EN 10340 G20Mn5 low alloy steel, 289Kg - 1,130Kg, finish machined & painted
Cable clamp bands are supplied with 100% ultrasonic testing, the zone around the pin hole is class 1 with no weld repair allowed.
Oakland Bay Bridge, San Francisco
The Oakland Bay Bridge is a pair of bridges spanning San Francisco Bay of California, in the United States. It carries approximately 270,000 vehicles per day on its two decks. The eastern span of the bridge underwent a seismic proof retrofit, opening in 2013. It has one of the longest spans in the US and is the worlds widest bridge.

The Jiangyin Yangtze River Highway Crossing, China
Consisting of a long span six-lane suspension bridge. The main span of the bridge is 1,385m, making it the fourth longest in the world when constructed.
Carbon Steel, 2,100Kg, finish machined & painted
A 12-bolt, 1,800mm cable band assembly undergoing dimensional inspection prior to packing.
Carbon Steel, 860Kg, finish machined & painted
Corrosion protection of cable bands is vital to the long-term life of a suspension bridge. Metal spraying with zinc is followed by further protection from sea water corrosion with a multi-coat two-pack epoxy resin paint system. Both metal spraying and painting is carried out at the Goodwin facility.
The Tsing Ma Bridge, Hong Kong
The Tsing Ma Bridge carries two three-lane carriageways on top of another twin lane carriageway next to a twin track railway line. At 2.2km long with a 1,377m main span it is the world's longest suspension bridge carrying both road and rail traffic.
