Headquartered in Wuxi, Jiangsu—the core metallurgical engineering hub within China's Yangtze River Delta—Wuxi Jianfa Machine-Building Co., Ltd. has spent over four decades driving innovation in heavy-duty coil processing. Designated as a National Key Developing Enterprise in the metallurgical machinery sector, our production facility houses in-house casting, high-precision gantry milling, CNC heat treatment, and specialized multi-axis drive integration.
We solve the most persistent challenges in sheet metal decoiling: internal residual stress buildup, transverse cross-bow, edge curling, and shear burr propagation. By engineering custom mechanical-hydraulic linkages with Siemens and Beckhoff automation backbones, Jianfa delivers automated turnkey Cut to Length Lines, Rotary Slitters, and Flying Shears that meet strict European CE standards and global ASME structural demands.
Integrated Supply Chain Hub
Direct expressway access to Shanghai Deep-Water Sea Ports facilitates reduced container staging lead times and lowers ocean-freight risks for overseas steel service centers.
Verified Process Audits
Every individual sub-assembly undergoes geometric static verification, dynamic continuous vibration damping analysis, and full-load running tests before ocean export.
Technical Roadmap & Future Outlook: Next-Gen Coil Shearing
The industrial shift toward ultra-high-strength automotive steels (AHSS), thin-gauge solar arrays, and high-purity electrical steels demands adaptive, intelligent coil processing.
AI-Driven Closed-Loop Adaptive Leveling
Next-generation Jianfa lines integrate laser profile sensors at the leveling exit that continuously measure sheet curvature. A closed-loop predictive algorithm automatically adjusts hydraulic cylinder roll intermesh in real time, compensating for yield variances across hot-rolled coils.
Dynamic Rotary Servo Shears
Replacing traditional stop-and-go hydraulic drop shears, our advanced direct-drive servo rotary shears travel in non-linear synchronization with high-speed lines, boosting throughput up to 120 cycles per minute while eliminating strip surface friction and hydraulic fluid dependency.
Automated Aerodynamic & Robotic Stacking
To eliminate stacking scratches on class-A automotive, mirror stainless, and pre-painted architectural coils, Jianfa combines air-cushion floatation chambers with high-speed gantry magnetic and vacuum robotic arms for automated bundle tying and digital barcode labeling.

Supply Chain Resilience, In-House Machining & Cost Efficiency
How Wuxi Jianfa's vertical manufacturing structure delivers superior quality machinery with up to 35% lower total capital investment compared to Western counterparts.
100% In-House Vertical Machining
We eliminate subcontractor margins and schedule bottlenecks. All base frames undergo thermal annealing stress-relief in our large furnaces, followed by single-setup CNC machining on five-face gantry centers to ensure rigid mechanical alignment.
Yangtze River Delta Industrial Density
Wuxi houses the world's most concentrated metallurgy engineering cluster. Sourcing premium alloy rolls (60CrMoV, Cr12MoV), induction drives, and hydraulic valves within a 50km radius enables us to achieve 90-120 day delivery timelines.
High Capital Efficiency & Proven ROI
Combining globally recognized components (Siemens PLC, Schneider electrics, Rexroth hydraulics) with cost-effective Chinese heavy mechanical fabrication gives buyers Western-grade reliability at a competitive capital expenditure.
Addressing Global Procurement Requirements: Quality, Safety & Delivery
Procurement teams require verifiable milestones, transparent FAT/SAT procedures, and risk mitigation across all project stages.
Factory Acceptance Test (FAT)
Before shipment, every line is assembled in our Wuxi facility and run using client-supplied test coils. We evaluate leveling flatness (I-units), length repeatability, hydraulic line pressure, and full-speed synchronized shearing.
Export-Grade Heavy Packaging
All precision roll surfaces receive anti-rust coatings and vacuum foil packaging. Solid steel-frame anchoring inside 40ft open-top and flat-rack containers prevents moisture exposure and motion damage during rough ocean voyages.

Frequently Asked Questions: Cut to Length Engineering
Key technical, commercial, and operational insights addressed by our senior metallurgical systems engineers.
How does a 6-Hi leveler differ from a 4-Hi leveler in CTL lines?
A 4-Hi leveler features top and bottom work rolls supported directly by backup bearings, which works well for standard hot-rolled carbon plates where small contact scratches are acceptable. A 6-Hi leveler introduces intermediate rolls between the work rolls and backup rolls. This setup distributes bending loads evenly and prevents strip marking, making it essential for processing stainless steel, aluminum, pre-painted coils, and high-yield cold-rolled metals.
What coil processing equipment does Wuxi Jianfa manufacture?
We build complete coil handling installations, including high-speed slitting lines (rotary shears), stop-and-go Cut to Length Lines, continuous flying shear lines, heavy-plate 4-Hi leveling machines, straightening units, and continuous galvanizing lines. Systems can be configured as complete turnkey setups or standalone retrofit stations.
What are the key differences between a stop-and-go CTL line and a flying shear?
In a standard CTL line, the steel strip halts for each cut, which works well for heavy-gauge plate (up to 25mm) but limits speed (usually 20-40 m/min). A flying shear moves the cutter alongside the strip at an identical forward velocity, cutting during continuous motion without deceleration. This approach delivers speeds up to 100-120 m/min while protecting the sheet from feed-roll marking.
Which raw material alloys and coil types can Jianfa lines handle?
Our systems process hot-rolled coils, pickled & oiled (P&O), cold-rolled carbon steel, hot-dip galvanized (GI), Galvalume, stainless steel (200, 300, and 400 series), titanium, copper, and lightweight aluminum alloys (1000 through 6000 series), with yield strengths ranging from 235 MPa up to 1200+ MPa.
How do you control and eliminate edge burrs during shearing?
We use precision shear blades forged from Cr12MoV, H13, or high-tungsten alloy steels, heat-treated to 58-62 HRC. Automated hydraulic blade gap adjustment lets operators change clearances directly via the HMI based on material thickness and yield strength, maintaining burr heights under 5% of nominal sheet thickness.
What parameters are needed to provide an accurate proposal?
To help us configure the right line, please provide: maximum coil weight, inner (ID) and outer (OD) coil diameters, strip thickness range, maximum coil width, material grade and tensile/yield strengths, desired cut lengths, daily or annual throughput targets, and your plant's power supply characteristics (e.g., 380V/50Hz/3P or 480V/60Hz/3P).
What international installation, commissioning, and warranty support is provided?
We send dedicated installation teams overseas to supervise foundation installation, mechanical leveling, hydraulic commissioning, and operator training. Our systems come with a comprehensive 12-month structural and mechanical warranty, supplemented by lifetime engineering support, rapid spare parts shipping, and remote IoT diagnostics.
Can buyers review equipment during manufacturing and perform an on-site FAT?
Yes. We encourage technical teams to visit our 40,000 m² factory in Wuxi, Jiangsu—located approximately 30 minutes from Shanghai via high-speed train. Clients can inspect machining tolerances, review assembly progress, and take part in full-load trial runs before final packing and dispatch.
