Steel sheet piling is a rolled structural steel section with interlocks on the flange tips which enable the joining of sections to form a continuous wall. Gerdau sheet piling has been successfully used in both permanent and temporary applications that cover the entire range of projects in the construction industry:
The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are descaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.
The coldrolling mill produced 80,000 tonnes of coldrolled steel products in March, with an operation rate of 80%—20% higher than projected. Since the beginning of April, the plant has been in full operation, producing 100,000 tonnes of steel.
