Rebar Thread Rolling Machine

Overview

The HGS-40 Rebar Thread Rolling Machine from Gongda (China Rebar Machinery, chinarebarmachinery.com) is built for thread-rolling 14–40 mm reinforcing bars for mechanical splices. It is designed for B2B buyers who need consistent, repeatable thread geometry on site or in a fabrication shop. Gongda is based in Hefei, Anhui, China, with a factory rooted in the electromechanical works of Hefei University of Technology. The HGS-40 is exported worldwide, including to Russia, Spain, Latin America, the Middle East, Southeast Asia, and Africa.

Key specifications explained

• Processing range: Ø 14–Ø 40 mm — covers the common rebar diameters used in mechanical splicing, reducing the need for multiple machines on one project.
• Main motor power: 5.5 KW — provides the torque required for thread rolling across the full 14–40 mm range.
• Spindle speed: 60–80 rpm — a controlled speed range that supports stable thread forming and repeatable results.
• Maximum thread length: 90 mm — accommodates standard mechanical splice thread lengths within the machine’s rated capacity.
• Power supply: 380V 50HZ — standard industrial three-phase supply; confirm site power compatibility before ordering.

Applications

The HGS-40 is used for preparing rebar ends for mechanical splices in reinforced concrete construction. Typical applications include:

• Building construction — columns, beams, slabs, and walls requiring rebar connection.
• Infrastructure projects — bridges, tunnels, and civil works where reliable rebar splicing is specified.
• Prefabrication yards — producing threaded bar ends in batch for later assembly.
• Projects using mechanical couplers — where thread quality and dimensional consistency matter.
