Import Bgzl-40b3 Rib Peelling Thread Rolling Machine — Buy in wholesale FOB from Supplier in China

The BGZL-40B3 is a dedicated rib peeling and thread rolling machine for processing structural steel bars prior to mechanical splicing. It first strips the longitudinal ribs and transverse ribs from the bar end, then cold-rolls parallel metric threads onto the reduced diameter section. This creates a straight screw thread connection compatible with standard couplers, eliminating the need for upset forging or welding. Hebei Yida Reinforcing Bar Connecting Technology Co., Ltd. positions this unit as the exclusive processing equipment for their straight screw thread connection system, with application to reinforced concrete structural elements. The machine handles bars up to 40 mm nominal diameter, though buyers should confirm the exact bar grade and yield strength range supported.

The BGZL-40B3 employs hardened cutting tools for rib removal, followed by thread rolling dies that form threads by plastic deformation rather than material removal. This preserves material continuity and typically achieves higher fatigue resistance than cut threads for rebar applications. Standard industry practice for such machines specifies rolling dies with thread profiles matching ISO metric coarse or fine series, with pitch commonly 2.5 mm or 3.0 mm for 25 to 40 mm bar. The peeling head must be adjusted to remove only rib height without excessive reduction of core diameter, as this affects thread engagement length and connection strength. Hydraulic or electric power drive options are typical in this machine class, with foot pedal or automatic cycle control. The supplier should clarify the BGZL-40B3 drive type, motor power and control system details.

Construction contractors, precast concrete manufacturers and rebar fabrication shops use this equipment to prepare bars for mechanical connections in columns, beams and pile cages. The rib peeling process is particularly valued in seismic zones and for large-diameter bars where lapped splices are impractical. Buyers should verify that the thread profile produced conforms to their national structural code and coupler supplier requirements, as thread form tolerances directly affect connection performance. Hebei Yida Reinforcing Bar Connecting Technology Co., Ltd. indicates the machine is for structural steel bar top-end processing, suggesting primary use in vertical element splicing where access to bar ends is available.

Hebei Yida Reinforcing Bar Connecting Technology Co., Ltd. is located at No.66 Qingyuan Street, Shijiazhuang, Hebei Province, China, with postal code 052160. The company holds a harbor trust tier and imported supplier tier on the platform, with a response rate of 0.00 percent and no recorded average response time. This profile indicates the supplier has passed certain verification checks but may not actively monitor enquiries through the platform. The business specialises in rebar connection technology, suggesting core competence in mechanical splicing systems and the equipment required to prepare bars for such connections.

The supplier's stated product, the BGZL-40B3, is described as an exclusive-use machine for straight screw thread connecting, with primary application to structural steel bar end processing. No additional machinery models, manufacturing area, employee count, annual turnover, or client references are provided in the source data. Buyers should conduct independent due diligence, including requesting business registration documents, factory audit reports, and video evidence of machine operation. The proximity to Shijiazhuang, a major steel and heavy machinery centre in northern China, offers potential logistics advantages for domestic steel supply and technical service access.
