At the construction sites of high-rise buildings, tens of thousands of steel rebars need precise connections. Workers use wrenches to quickly butt two rebars via threaded ends — this is the revolutionary construction method brought by the rebar thread rolling machine. Each joint only takes one minute to finish, with no open flame, zero pollution, and round-the-clock operation. Compared with traditional welding, this threading machine for steel rods not only greatly shortens the construction period but also eliminates potential safety hazards. YG Machinery supplies a full line of rebar thread rolling machines to meet diverse demands from small construction sites to large precast factories.

What Is a Rebar Thread Rolling Machine?
rebar rolling machine, namely a rebar thread rolling machine, is professional equipment for machining straight thread ends of steel rebars. It adopts rib peeling and rolling technology, which applies plastic deformation to rebar ends through rolling dies to form standard straight threads. Unlike cutting processing, rolling technology will not damage the base material of rebars. Instead, the cold-hardening effect raises the tensile strength of threaded parts by 20%-30% and fatigue resistance by 40%-60%. Rebars processed by this rebar thread rolling machine have connection strength even higher than the rebar base material itself, making it the preferred connection solution for high-rise buildings, bridges, tunnels, and other projects.
4 Advantages of YG Rebar Thread Rolling Machine
1. Complete the whole process with one-time clamping
YG threading machine for steel rod features a unique automatic opening and closing cutter mechanism. It can finish rib peeling and thread rolling continuously after the rebar is clamped once. Unlike traditional machines that require repeated adjustments, our equipment cuts processing time by over 50%. The fully automatic YGA-40 model supports one-touch forming, finishing one thread end in only 8 seconds.
2. Compatible with both forward and reverse threads
YG machines easily handle both right-hand and left-hand threads. This flexibility delivers greater convenience for precast component factories and complex structure construction. One single machine satisfies all kinds of rebar connection requirements.
3. No cutting on base material for higher strength
Unlike low-cost cutting-type rebar threading machines, YG applies rolling craft without destroying the fiber structure of rebars. Processed thread ends have a smooth surface and full tooth profile, with dimensional accuracy compliant with ISO standards. Its connection reliability far exceeds welding and binding methods.
4. Easy operation & low maintenance cost
The machine boasts a compact overall structure and intuitive control system. New operators can master skilled operation after simple training. YG provides a full range of portable rebar threading machine spare parts and wearing parts to guarantee long-term stable operation of the equipment.

FAQ about Rebar Thread Rolling Machine
Q1: What factors affect rebar threading machine price?
A: The price mainly depends on machine model, processing capacity, automation level, and configuration. Standard YGS-40 fits small and medium-sized projects, while fully automatic YGA-40 is ideal for mass production. YG’s direct sales model helps customers get the most competitive rebar threading machine price.
Q2: Is a portable rebar threading machine suitable for on-site construction?
A: Absolutely suitable. YG machines are compactly designed with moving wheels at the bottom for easy transportation to different working stations. The weight of 320- 400 kg balances stable performance and mobility, making it the optimal choice for on-site rebar processing.
Q3: How long does it take to process one thread end?
A: Around 15 seconds per piece for standard YGS-40, 8 seconds for upgraded YGT-40, and one-touch automatic completion for fully automatic YGA-40. Its efficiency is 3-5 times higher than traditional welding.
Q4: What maximum diameter of rebars can the machine process?
A: All models of YG rebar thread rolling machines can process ribbed rebars with diameters from 16mm to 40mm, covering over 90% of common specifications in the market.
Q5: What to do if threads fail to roll out or get disordered during processing?
A: Common causes include the wrong rotation direction of the rolling head, mismatched rolling head specifications with rebar, incorrect order of positioning sleeves, or faulty installation sequence of rolling heads. Check the above items first when problems occur, and replace damaged rolling dies or positioning sleeves if necessary.
Q6: What advantages does rebar rolling machine have over traditional rebar connection methods?
A: Compared with traditional welding, the connection made by a thread rolling machine is purely mechanical. It is not affected by construction seasons, is free of open flame and pollution, safe and reliable. Each rebar joint only takes about one minute to complete, greatly shortening the structural construction cycle. Moreover, the rolling process does not cut the rebar base material, so the thread end strength exceeds the base material, with guaranteed connection performance.
