New electric rebar threading machines for rebar diameters 12-50 mm list from US$980 per set at 1-unit MOQ on Made-in-China as of 2026-05-31, with three-roller thread-rolling configurations dominating the entry tier [S6]. Mid-range CNC automatic rib-peeling and thread-rolling machines from Hebei Xushi Weiye target higher-cycle rebar mills and are quoted on direct inquiry [S1]. GM350-class units suited to anchorage production carry a published reference price on Okorder with a 20-unit-per-month supply capability from Tianjin [S5].
For a process engineer building a coupler-line budget, the realistic 2026 spread — entry electric to large hydraulic thread-rolling — runs roughly US$980 to US$5,000+ per set on China B2B platforms, before tooling, spares, and freight. Diameter range, motor power, roller count, and whether the line includes rib-peeling and upset forging are the four levers that move a quote more than brand alone. The threads produced are rolled rather than cut, which preserves the grain flow of the rebar and is the reason couplers spec rolled threads.
Price Tiers Observed on China B2B Platforms (June 2026)
Three reference price points anchor the 2026 market. A three-roller electric thread-rolling machine, 1-set MOQ, CCC/ISO9001/CE certified, is listed at US$980/set on Made-in-China, with OEM/ODM and sample availability confirmed [S6]. A rebar bending and threading package from a Mainland supplier carries a US$1,799/set, 1-set MOQ, with L/C, T/T, D/P, PayPal, Money Gram, and Western Union accepted as payment terms [S3]. GM350 anchorage-class units are quoted on Okorder under reference-price terms, with Tianjin as the loading port and TT or LC as the standard instruments; monthly supply capability is 20 units [S5].
The CN-side spread is wide because the machine category covers a roll-form threader for #4 (12 mm) bar, a CNC rib-peel-and-roll line for #8 (25 mm) construction bar, and a hydraulic upsetting/threading cell for anchorage components [S1][S5]. A buyer who only sees the US$980 anchor will over-spec on a small jobsite; a buyer who anchors on a US$5,000 line will under-spec a mill running 40Cr/45# rebar couplers at high cycle.
What Drives the Quote: Motor, Roller Geometry, Diameter Range
Three specifications move a rebar threading machine price more than any other. First, motor class: small single-phase units for 12-25 mm bar sit at the bottom of the range; three-phase 4-7.5 kW motors for 25-40 mm bar move the quote up one tier; hydraulic thread-rolling heads for 32-50 mm bar sit at the top [S1][S4]. Second, roller count: a two-roller threader is the lowest-cost geometry, while a three-roller thread-rolling machine distributes forming force more evenly and is the dominant OEM choice for #6-#8 rebar at 1-set MOQ US$980 [S6].
Third, the diameter window and the inclusion of upstream rib-peeling and downstream upset forging. BARTECH lists full-size standard rebar couplers plus positional and transition couplers, with 40Cr and 45# carbon steel as the standard material pair for the mating threads — that material pairing is what the threading machine's roller hardness and feed geometry have to be tuned for [S4]. A line that only rolls threads will be cheaper than a line that peels ribs, rolls threads, and upsets the bar end in one pass; the latter is the configuration typically specced for high-cycle rebar-processing mills [S1]. A useful sibling reference for the upstream cutter side is the Rebar Cutter 2026 Price and Cost Guide, which covers the diameter and drive levers that pair with a threader on the same line.
FOB vs Landed Cost: Freight, Duties, and Spare Rollers
The published US$980 and US$1,799 figures are FOB China, with freight and estimated delivery to be confirmed with the supplier [S3][S6]. Sea freight from Tianjin or Shanghai to a Middle East port typically adds 8-15% to a single-machine order, and Dubai-destined showroom listings confirm that regional buyers price against the CN-side figure plus CIF markup [S2]. For a one-line buyer, the spare-roller and rib-peeling-disc set is a recurring cost: rollers for 40Cr/45# coupler threads wear and must be resupplied, and a buyer who treats them as consumable rather than CapEx will land closer to the true lifecycle figure [S4].
Payment-instrument choice is part of landed cost as well. L/C adds 1-2% bank charges but unlocks larger OEM credit lines; T/T 30/70 is the most common middle path on Made-in-China listings; PayPal and Western Union appear on smaller-MOQ offers and are typical for sample or single-unit shipments [S3][S6]. A 2026 buyer comparing two CN suppliers at the same headline price should normalize the quote to the same Incoterm, the same payment instrument, and the same roller/spare package before declaring a winner.
Who This Category Is For — and Who It Is Not
A roll-form rebar threading machine is the right tool for any operation that produces mechanical splices — rebar couplers, anchor bars, and threaded continuity bars in concrete — at a cycle rate that justifies a dedicated cell. That includes precast yards producing 40Cr rebar couplers, bridge and metro projects using transition couplers, and mining/tunneling operations threading anchorage bars at 32-50 mm [S4][S5]. It is also the correct upstream tool for any line that needs rolled threads to mate with rebar couplers — cut threads remove material and weaken the bar, which is why rolled threads dominate the spec.
It is the wrong tool for a small jobsite that only needs a few hundred threaded ends per month. A hand-held rebar threading die on a brace-and-socket setup is cheaper per end and faster to deploy for that volume, and it leaves no machine to store, ship, or maintain. It is also the wrong tool for a buyer who needs a linear guide or a crossed-roller guide for a CNC machining center — those are motion-control components, not rebar-processing machines, and the two categories are frequently cross-searched but should not be cross-spec'd.
Selection Criteria and a Side-by-Side Comparison
Four criteria line the main options up against each other. A buyer ranking a 12-25 mm entry electric threader, a 25-40 mm CNC rib-peel-and-roll line, and a 32-50 mm hydraulic upset-and-thread cell should score each on diameter range, thread geometry (two-roller vs three-roller), cycle rate, and price band. The entry tier wins on price and footprint; the CNC tier wins on thread profile consistency and reduced operator skill; the hydraulic tier wins on diameter window and on integration with upset forging for anchorage [S1][S4][S6].
For buyers who need a deeper process spec on the threading side, the Rebar Threading Machine 2026 Buying Guide covers spec, sourcing, and cycle in more detail and pairs cleanly with this cost guide. For buyers who also need the upstream cutting cell on the same line, the Rebar Cutter 2026 Price and Cost Guide covers the drive, diameter, and sourcing levers on the cutter side. For buyers sourcing the bar itself, the Rebar encyclopedia entry covers grade, standard, and diameter selection.
Standards, Materials, and Sourcing Discipline
Two material specs govern the threading geometry. Standard rebar couplers are produced in 40Cr and 45# carbon steel, with positional and transition variants in the same material family [S4]. That is the material pair the roller's hardness and surface finish have to be tuned for; a machine specced for 304/316 stainless will not deliver the same cycle life on carbon-steel couplers. For the upstream and downstream cells, the rebar bender and rebar threading machine encyclopedia entries cover the bend-radius and thread-rolling parameters that have to match the coupler spec.
Three sourcing rules hold in 2026. First, normalize every CN quote to the same Incoterm, payment instrument, and roller/spare package; FOB prices on Made-in-China and Okorder are list prices, not delivered prices [S3][S5][S6]. Second, verify that the supplier holds CCC, ISO9001, and CE where the destination market requires them; these are listed on the entry-tier three-roller offer and should be a baseline filter [S6]. Third, confirm the diameter window against the actual job mix — a 12-25 mm machine on a 32 mm rebar will not produce a usable thread, regardless of price.
Trackable signals to watch: any revision of CCC certification scope for thread-rolling machines, any change in the Tianjin/Shanghai FOB spread against CIF Dubai/Jeddah benchmarks, and any shift in the entry-tier US$980 floor on 1-set MOQ offers. A buyer running a tender in 2026-Q3 should re-quote at least two of the three reference suppliers — Made-in-China three-roller, Xushi CNC rib-peel line, and Okorder GM350 — before placing a PO.
