Overview

Pearson Manufacturing supports the production of bent tubular components through CNC rotary draw, mandrel, and roll bending processes. Some tubing jobs are fulfilled at our Ontario facility, while others — particularly large-format or high-volume — are handled through our Canadian supplier network.

From tight-radius bends for hydraulic lines to complex structural tube profiles, we coordinate quoting, tooling, QC, and logistics to ensure accurate and repeatable results across mild steel, stainless, aluminum, and more.

Quick Specs

Processes
Rotary draw (mandrel), roll bending, compression (by review)
Size Range
OD ≈ 0.25″–4″+ (wall & radius dependent)
Typical CLR
≈ 2–3 × OD (tighter with mandrel & thicker walls)
Angle Tolerance
±1° typical (tighter by engineering review)
ProcessBest ForThroughputNotes
Rotary Draw (Mandrel)Tight radii, precise geometry, minimal ovalityMedium–HighFixed-radius dies; best for hydraulic lines, frames
Roll BendingLarge, sweeping arcs; long parts & sectionsHighAdjustable radius; structural & aesthetic curves
Compression BendingSimple bends on thicker wallsHighLower tooling cost; less control on thin walls

Our Tube Bending Capabilities

  • Rotary draw & mandrel bending for tight-radius control and reduced ovality
  • Roll bending for long, gradual curves and structural profiles
  • Round, square, and rectangular tube profiles
  • Pre-/post-bend services: cutting, coping/notching, end-trim
  • Fixture welding or assembly-ready prep on request
  • In-process verification: angle checks, go/no-go, barcode/traceability

Design for Manufacturability (DFM)

  • Choose a standard centerline radius (CLR) when possible — ~2–3× OD is a good starting point for many materials; tighter radii often require mandrel tooling.
  • Leave straight length between bends at least ≈ the bend radius (R) or ≈2×OD; more space improves clamping and consistency.
  • Call out allowable ovality/flattening on critical sections; tighter ovality may require mandrel and thicker walls.
  • Provide full bend data: OD, wall, material/temper, CLRs, degrees, distances-between-bends (DBB), end lengths, and bend direction/plane.
  • Keep holes, slots, or notches away from bend tangents; place features after bending when feasible or allow generous distances.
  • Use one common CLR across a part when practical to reduce tooling and lead time.

Figures are guidelines. We’ll review your drawing/CAD and confirm achievable specs with the best routing (in-house or partner) before kickoff.

Typical Applications

  • Hydraulic and pneumatic routing lines
  • Automotive/off-highway frames & guards
  • Architectural handrails and railings
  • Industrial racks, ladders, and supports
  • Furniture tubing & curved members
  • Motorcycle/powersport & bike components

FAQs

What’s the max tube size you support?

We support round tube bending up to ~4″+ OD and structural square/rectangular tubes up to ~6″ width, subject to radius and wall thickness.

Do you offer end forming or welding?

Yes — trimming, coping/notching, and welding are available through our integrated fabrication services.

What information should I include for a quote?

Material/temper, OD, wall, bend radii and angles, end lengths, DBB, tolerances (angle/ovality), quantity, and any finishing or assembly requirements.

Need Precision Tube Bending?

Upload your tubing specs or CAD files and we’ll coordinate CNC bending — whether at our facility or via our national supplier network.
