Dywidag tie bars are discontinuously threaded rebars. It is a type of hot-rolled concrete tie rod. Among the hot-rolled dywidag tie rod, the sizes of dw 15 and dw20 are the most popular sizes.
Hiscaffold’s dywidag type concrete tie rods are made from 830 and 930 steel grades. The ultimate load of the 15mm hot-rolled dywidag bars is reaching 201KN. Thus, the dywidag threaded concrete tie rod is also called heavy load capacity construction rebar. Discontinuous threaded make the concrete tie rods self-cleaning in construction after working from the concreting.
2. Cold rolled tie bars
Compare to hot rolled dywidag bars, the cold-rolled concrete tie rods are threaded from a steel round bar structure. According to the steel grade, Hiscaffold can supply S235, S450, and 42CrMo cold roll steel coil rods for your construction. The different steel structure grade brings your different grade of concrete tie rods. Take D16(15/17mm) sizes for an example:
