Greatcity Thread Rolling Machine

The Greatcity Thread Rolling Machine is designed to form screw threads on rebars for construction and manufacturing applications, enabling the use of threaded splices, couplers and other rebar connections without cutting or welding.

The machine accommodates a wide range of commonly used construction rebar diameters and typical carbon-steel rebar grades. Exact supported diameter ranges and special-material compatibility (e.g., stainless or high-alloy steels) depend on tooling and configuration — please consult the specification sheet or contact sales for your required sizes.

The machine can produce standard thread profiles used in rebar splicing. Thread form and pitch are determined by the rolling dies/tooling. Standard and custom thread profiles can be supplied — confirm required thread standard (metric, custom coupler profile, etc.) when ordering.

Machine dimensions are 2150 mm x 1800 mm x 1600 mm (L x W x H). For shipment each unit is securely packed in a wooden case to ensure safe transportation.

The machine is equipped with core components including an engine, bearing and motor. Exact motor power, fuel/electric requirements and drive options vary by model and configuration — please request the electrical/power specification for the model you are purchasing.

Production rate depends on rebar diameter, thread length, material and operator workflow. The machine is engineered for high efficiency, but for expected throughput estimates provide your typical rebar sizes/production targets and we can supply performance data or cycle-time examples.

Yes — the Greatcity machine is designed for user-friendly operation with straightforward controls to minimize operator training time. The purchase includes video technical support; on-site training or additional instruction can be arranged if required.

Regular preventive maintenance includes lubrication of bearings, inspection and replacement of rolling dies/tooling, and periodic checks of the drive system and safety devices. Maintenance intervals depend on usage intensity; a recommended maintenance schedule is provided with the machine and technical support is available.

The Greatcity Thread Rolling Machine is CE certified, indicating compliance with relevant safety and machinery directives. It also includes standard safety measures (guards, emergency stops and interlocks). Specific safety features are detailed in the machine manual and can be confirmed prior to purchase.

Each unit ships with a machinery test report and a video of the outgoing inspection. Technical documentation, operation manuals and video support are provided to help with commissioning and operation.

Yes — spare parts and after-sales technical support are available. The machine purchase includes access to video technical support, and genuine replacement parts can be supplied through the manufacturer or authorized distributors.

Yes — the machine can be customized to meet specific requirements such as special thread profiles, different power configurations, or integration with automation and feeding systems. Contact the sales team with your specifications to discuss options and pricing.

Warranty terms and delivery lead times vary by sales agreement and destination. Standard warranty and estimated delivery schedules are provided at time of quotation — contact the sales representative for current lead times and detailed warranty information.
