These machines cold-roll a parallel thread onto a rebar by first stripping its ribs and then rolling threads onto the end. This method preserves the bar's strength and produces high-precision threads for couplers—ideal for constructing reinforced concrete structures

Rebar thread rolling machines use cold-forming to strip ribs and roll external threads onto TMT bars without cutting—which preserves the steel’s strength and creates durable, high-integrity threads Most work with diameters from 12 mm to 50 mm, producing thread lengths up to 100–120 mm with motor power around 4–5 kW and speeds of 40–80 r/min.

📌 Key advantages:

• Maintains tensile strength (cold-forming vs. cutting)

• Fast operation (≈30 s per bar) 

• Compact and site-friendly

A rebar threading machine is used to apply threads to the ends of reinforcement bars (rebars). The threaded ends of the bars are then used in conjunction with mechanical couplers to connect and strengthen concrete structures without the need for welding.

These machines are a crucial part of the construction industry as they allow for quick, secure, and cost-effective connections between rebars, making them highly suitable for large-scale projects, especially in reinforced concrete construction like bridges, high-rises, and foundations.
