International Paint Supports ZPMC to Build San Francisco's Oakland Bay Bridge
March 16, 2010
AkzoNobel protective coatings supplied by the company’s International Paint Protective Coatings business will be used to paint the 45,000-ton steel structures being used for the new east span of San Francisco’s Oakland Bay Bridge, to be built by Shanghai Zhenhua Heavy Industry Co., Ltd (ZPMC). The first batch of steel structures were fabricated and coated in Shanghai and shipped to San Francisco on December 29, 2009. The self-anchored suspension bridge has a number of state-of-the-art seismic safety features that are the first to ever be used in bridge construction. The bridge’s west span has already undergone a significant seismic retrofit, while the east span on the Oakland side is being completely replaced. In concurrence with the California Department of Transportation, ZPMC chose International Paint protective coatings because they are manufactured with the same quality standards in all of their 20 worldwide locations. A total of 100,000 gallons of Interzinc 22 Inorganic Zinc Rich Silicate and Interfine 979 Acrylic Polysiloxane will be used in the project to provide anti-corrosion, abrasion, impact-resistance, and gloss and color-retention protection. The coatings meet California’s rigorous building requirements and will extend the performance life-cycle of the bridge, providing further savings on long term maintenance costs.
