New Shougang Bridge – Beijing

The design of the bridge is from the Belgian architect Nicolas GODELET of Beijing Gejian Architectural Design Consulting Co Ltd and living in Beijing It is an entirely welded steel structure with 45 000 tonnes of steel plates (more than for the National Stadium “Bird’s Nest”).

Coating with ZINGA started in 2017. In total 182 tons of ZINGA was used (internal and external of steel structure). It is the world’s first twin tower cable stayed steel composite bridge. 1 354 meters in length and 54 9 meters in width. It is the highest bridge in Beijing City with two distinct steel arch towers of 125 and 90 meters, 4 lanes in both directions, and it is the widest bridge in China. The bridge opened to trafic on 29 September 2019.

The external was coated with ZINGA 1 x 60 µm DFT and topcoated with AkzoNobel I.P. mid- and topcoats. The internal application was a ZINGA-unique system of 1 x 80 µm DFT.

The Sierhierkowski Bridge in Warsaw

The application took place in September and October of 2008. The investor for the renovation of the complete 500m long and 35m wide bridge was the General Directorate for National Roads and Motorways. The contractor was GS-STEEL from Gdansk. In total, 1.322 Kg of ZINGA were used to protect this magnificent bridge against corrosion.

The anti corrosion protection technology before renovation was:

  • Metallisation 120µm
  • Sealer, Intermediate coat and Topcoat; Total 200µm DFT

Surface preparation: Grit blasting

ZINGA 1 x 120µm DFT application by brush where the metallisation was removed (30% of the complete surface). Over the complete surface Sealer, Intermediate coat and Topcoat; Total 200µm DFT

 

 

 

El Salaam Bridge

The treatment of the El Salaam Bridge in Egypt, was part of the Bridge Maintenance Program in 2007. This bridge carries a gas pipeline of the Egyptian Natural Gas Company (GASCO). The bridge had suffered severe corrosion.

Burdekin Bridge

The Burdekin Bridge (known as the Silver Link) spans the Burdekin River between the towns of Ayr and Home Hill, Queensland, Australia. Located on the Bruce Highway which is part of Highway 1, it is an important link in the national road network.
It is a road-rail bridge which provides high flood immunity link between north and south Queensland. The Bridge was completed in 1957. Construction began 10 years earlier in 1947. 1103 meters in length, it is one of the longest multi-span bridges in Australia.

ZINGA has been used since 2005 for patch repair. During 2010/2011 the under road areas of the 22 approach spans have been coated with ZINGA.

In the beginning of 2013, the road support structures were coated with ZINGA specified as a class Sa2½ abrasive blast clean followed by 2 coats of ZINGA to an average dry film thickness of 180 μm. The coating system for the rail support structure required a decorative silver finish, and the coating system was therefore as described but incorporated a coat of AluZm. A dry film thickness of 40 μm was specified.
