Shanghai Zhenhua Heavy Industries, the world’s largest crane and steel structure manufacturer, supplied 250,000 incorrecly-sized bolts for the new eastern span of the San Francisco-Oakland Bay Bridge in California, reports the financial news website of financial market software developer Shanghai Great Wisdom.

The company, which manufactured and supplied the bridge’s deck and towers, said the bolts were purchased from a contractor. They decided to check the bay bridge project’s structure after a California senate report indicated that the incorrect size of blots had been supplied by the company for the US$6.3 billion Carquinez Bridge to Vallejo.

The report said the California Department of Transportation hired a group of quality-assurance specialists to audit the Chinese company and have suspended it from continuing to work on the new bay bridge. The specialists found over a hundred cracks in the bridge welded by the company. The group leader, engineer James Merrill, said the California state agency took a great risk in letting the Shanghai company do the work. The agency said the cracks have mostly been repaired, however, and stressed that the bridge is now safe.

The California Department of Transportation decided to rebuild the San Francisco-Oakland Bay Bridge after the original one was damaged by two earthquakes. In June 2006, the Chinese company obtained the right to manufacture all steel structures on the new bridge from US general contractor ABF Construction. The new bridge was completed in July 11, 2011 and the San Francisco mayor dedicated the day to Li Jianghua, in honor of the Chinese manager who oversaw the project, according to Shanghai Zhenhua’s statement.
