Durable ASTM A416 Steel Wire Prestressing Strand for Builders

Product Description

Product Description

 

1x7 prestressed steel strand, low relaxation pre-stressed steel strand is composed by 7 wires, it has the features of high tensile strength and very low relaxation, which make it could replace traditional deformed steel bar well, and save a lot of steel material. Meanwhile ,it make long span concrete construction be possible.
