Q:According to the Chinese standard, what are the specification and size of PC steel strand?

According to Chinese standard GB/T 5224-2014, the diameter range of PC strand wire is usually 3.0mm to 12.5mm. The common diameter specifications include 3.0mm, 4.0mm, 4.8mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, 9.53mm, 11.11mm and 12.5mm. The ordinary PC strand wire's construction is made up of 7 wires and this is the most common form of construction. Other construction forms can be used depending on specific requirements, such as stranded wire with 2, 3, 19 or more wires.The tensile strength of PC strand wire is the maximum tensile force that the strand can withstand. The common tensile strength grades include 1770MPa, 1860MPa, 1960MPa and 2000MPa.
