  • Product Description
  • Thread rolling is a metalworking process primarily used to cut helical threads on the external surfaces of cylindrical metal workpieces—such as reinforcing bars, steel pipes, and bolt blanks—to enable mating and fastening with internally threaded components like nuts and pipe fittings. In construction engineering, thread rolling is extensively employed for rebar connections (e.g., straight‑thread sleeve couplings) and pipeline installation, serving as a critical operation that ensures the strength and dimensional accuracy of jointed assemblies.

The primary function of the reinforcing cage is analogous to that of the longitudinal reinforcement in columns: it primarily resists tensile forces. Concrete exhibits high compressive strength but very low tensile strength.
