HARSLE plate rolling machines bend sheet and plate metal into cylinders, cones, and arcs — essential for tanks, pipe sections, and structural fabrication. HARSLE offers four series covering different structures and budgets: the QuadRoll 4-roll for high-precision plate bending, the TriRoll 3-roll for general-purpose plate rolling, the AsyRoll asymmetric design for thin plates and cost-sensitive work, and the AngleRoll profile bender for structural sections like angle iron and channel steel.
| Series | Structure | Best For | Max Capacity | Models Available |
|---|---|---|---|---|
| QuadRoll | 4-roll, hydraulic + CNC | High-precision plate bending, pre-bending both ends | Up to 40mm plate | 0620, 1020, 3020, 4020 |
| TriRoll | 3-roll, mechanical | General plate rolling, cylindrical and conical work | Up to 40mm plate | 0420, 1020, 3020, 4020 |
| AsyRoll | Asymmetric 3-roll, offset lower roll | Thin plate, cost-sensitive, single-setup feeding | Up to 6mm plate | 0210, 0410, 0420, 0620 |
| AngleRoll | 3-roll profile bender | Structural steel: angle iron, flat bar, tube, channel | Up to 500cm³ section modulus | 06, 75, 180, 500 |
What's the difference between 3-roll and 4-roll rolling machines?
4-Roll (QuadRoll) allows pre-bending both ends without repositioning, ideal for precision work with minimal flat ends. 3-Roll (TriRoll) requires repositioning for pre-bending but is more economical for general applications.
How accurate is a HARSLE plate rolling machine?
HARSLE rolling machines with CNC control achieve diameter tolerance of ±1mm, with roundness accuracy of 99%+ on the QuadRoll series. The hydraulic system maintains consistent pressure throughout the rolling process.
What materials can be rolled?
Mild steel, stainless steel, aluminum, copper, and alloy steels. Maximum thickness varies by material — stainless steel capacity is roughly 60% of the mild steel rating, aluminum roughly 150%. Pre-heating is available for thick plates.
What is the typical delivery time?
Standard rolling machines are typically ready for shipment within 3-6 weeks. HARSLE maintains inventory in its China factory for faster delivery on popular models; large-capacity machines may require 8-12 weeks.
What warranty does HARSLE provide?
All HARSLE rolling machines come with a 3-year warranty covering the hydraulic system, electrical components, CNC controller, rollers, and frame structure. Extended warranty packages are also available.
What is the minimum rolling diameter?
Minimum diameter is typically 1.2-1.5 times the upper roller diameter. The QuadRoll series' pre-bending capability allows smaller minimum diameters with reduced flat ends compared to 3-roll machines.
