More than 1700 tons of Ansteel’s bridge steel has been delivered recently from Bayuquan Branch of Angang Steel Co., Ltd. They will be soon after used for the world’s largest-thrust steel arch bridge - Guantang Bridge in Liuzhou, Guangxi. Ansteel made mass production of the supplied Q370qd bridge steel for the first time. Ansteel’s Production, Marketing and Research Team for bridge steel kept following up in time the progress of the project during the bidding period. They eventually won all the contracts in a total of 13000 tons of steel for the box beams for main part of Guantang Bridge.
