HAIHUI · REBAR PROCESSING GUIDE
A rebar thread rolling machine prepares bar-end threads for compatible mechanical couplers. Start with the connection specification, then choose the machine and tooling. The Haihui HGS40 and HGS50 listings have different published bar ranges; the model name is not a substitute for those specifications.
HGS40 and HGS50 published ranges
Haihui lists HGS40 for 16–28 mm reinforcing bar with a 4 kW motor. HGS50 is listed for 16–40 mm bar with a 7.5 kW motor and an 80 mm processing length. Both list machine dimensions of 1100 × 600 × 1100 mm. These are machine dimensions, not export packing dimensions. Material grade and thread requirements still need application review.
Define the connection before ordering rollers
Provide the coupler drawing, thread pitch, thread length, required engagement and bar specification. Clarify whether different coupler systems will be processed on the same machine. Tooling and gauges must correspond to the approved connection. Do not assume that matching nominal bar diameter alone proves compatibility with a coupler.
Plan the upstream and downstream operations
Discuss how bar ends will be cut, supported, inspected and identified. Confirm which end-preparation operations the selected setup performs and which remain separate. A useful production trial starts with the same incoming bar condition as the workshop will use. Include handling and inspection when assessing output rather than timing only the threading head.
Agree a sample inspection record
Ask for sample threads made using the intended material, rollers and coupler specification. Record the setup and agreed inspection method, including the specified gauges where applicable. Connection approval and any required testing follow the project requirements; a machine demonstration alone does not certify a completed structural connection. List rollers, gauges, couplers and other accessories individually in the quotation.

Frequently asked questions
Is HGS40 automatically suitable for 40 mm bar?
No. The current Haihui HGS40 sheet lists 16–28 mm. HGS50 lists 16–40 mm, subject to the application and tooling review.
Are couplers and thread gauges included?
Confirm them separately in the written quotation. A machine listing does not establish accessory inclusion.
