Stainless Line Specifications
Dual-function modular layout combining high-capacity steel coil uncoiling, multi-strand slitting, and synchronized cut-to-length packaging.
Combined Line OverviewIn modern metallurgical lines, the steel coil decoiler (uncoiler) is no longer a static mechanical spindle. It functions as the critical primary tension-control node governing entire slitting, roll forming, and tube-welding operations.
For European and global tier-1 buyers, CE compliance requires rigorous risk assessments under the Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and EN 60204-1 electrical security. Our certified decoilers integrate dual-circuit hydraulic locking, hydraulic snubber rolls with anti-loosening retainers, and interlocking safety enclosures to mitigate rotational coil kinetic hazards.
Advanced AHSS (Advanced High-Strength Steels) and UHSS automotive sheet demand continuous, vibration-free back-tensioning. Our uncoiling systems replace conventional friction banding with pneumatic air disc brakes or AC vector motor regenerative braking, monitored via non-contact ultrasonic coil diameter sensors to ensure consistent line tension without strip scratching.
To maximize line uptime, modern steel processing facilities demand fully integrated hydraulic coil loading cars with V-shaped saddles, motorized traverse drives, and optical centering lasers. This reduces coil changeover time from 20 minutes down to under 3 minutes, significantly improving overall equipment effectiveness (OEE).
Combining over 40 years of metallurgical mechanical expertise with complete in-house fabrication, heavy CNC boring mills, heat treatment facilities, and direct deep-water port proximity in the Yangtze River Delta.

From automotive tier-1 blanking lines in North America to infrastructural structural pipe manufacturing across the Middle East, our steel coil decoilers deliver continuous reliability.
Delivering uncompromised strip surface integrity for exposed automotive panels (CR, galvanized, aluminum alloy 5000/6000 series). Decoilers feature motorized snubber rolls with soft polyurethane lining, peeler knives, and automated edge-centering photo sensors (EPC) to ensure clean uncoiling without strip marring.
Handling thick-wall hot-rolled carbon steel coils up to 25.4mm thickness. High-capacity single-mandrel decoilers with outboard hydraulic support stands bear 35-ton coils, operating in synchrony with strip accumulators and shear welders to sustain uninterruptible 24/7 continuous tube extrusion lines.
Precision micro-tension decoilers designed specifically for silicon steel coils (grain-oriented CRGO / non-oriented CRNGO). Equipped with non-contact laser diameter monitors and magnetic hysteresis brakes to maintain exact strip tension and eliminate thin-gauge edge deformation.
Every machine manufactured in our facility undergoes rigorous stage-by-stage non-destructive testing (NDT), electrical safety checks, and continuous 72-hour full-load dry commissioning before export crating.
Authoritative insights straight from Wuxi Jianfa’s mechanical and electrical engineering departments.
Our decoilers conform to the European Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. Relevant harmonized engineering standards include EN ISO 12100 (Safety of Machinery - General Principles for Design), EN 60204-1 (Electrical Equipment of Machines), and EN 13985 (Shearing & Slitting Machine Safety).
We integrate closed-loop feedback using non-contact ultrasonic distance sensors or laser meters that calculate instantaneous master coil diameter. The PLC (Siemens S7-1500 or Mitsubishi iQ-R) modulates the pneumatic proportional valves or the regenerative AC vector motor torque in real-time, maintaining consistent web back-tension and preventing strip slack or necking.
An outboard support stand (hydraulic pivot bearing) is mandatory when the combination of coil weight (>15 tons) and coil width (>1,250mm) creates high bending moments on the main spindle. The hydraulically locked outboard arm eliminates spindle deflection, protects the main spherical roller bearings, and preserves uniform mandrel expansion.
Standard mandrel expansion covers 480mm to 520mm (nominal 508mm / 20" ID). To accommodate large-diameter mill coils (610mm / 24" or 760mm / 30" ID), our decoilers are supplied with rapid-mount segmented cast-steel expansion shoes or rubber vulcanized spacer rings with mechanical quick-lock toggles.
Standalone hydraulic decoilers require 35 to 50 days; fully automated coil lines with decoilers, straighteners, and slitters take 75 to 90 days. Equipment is coated in corrosion-inhibiting VCI wax, wrapped in heavy multi-layer moisture barrier film, and secured to structural steel skids with heavy turnbuckles in 40ft OT or standard containers.
