We have launched new product D15/17 TIE ROD (diameter 15mm, yield strength 830MPA, tensile strength 1030MPA) for customers.
The length of the finished thread reinforcement is usually 9Â m and 12 m.
the THREAD BAR diameter is from 15MM to 50MM
The grade of yield strength tensile strength post-fracture elongation is as follows:
PSB830, yield strength 830MPA, tensile strength 1030MPA, elongates after fracture 6%
PSB930, yield strength 930MPA, tensile strength 1080MPA, elongates after fracture 6%
PSB1080, yield strength 1080MPA, tensile strength 1230MPA, elongates after fracture 6%
There are no ribs on the threaded bar which means the hex nut or coupler can be used at any point.
