Precision Straightening Machine for Shaped Metal – Perfect Geometry for Complex Profiles

- 2 min read
Advanced multi‑axis straightening technology delivers flawless linearity, twist correction, and surface integrity for square, rectangular, hexagonal, channel, angle, and custom‑shaped tubes and bars.
Why Shaped Metal Needs Specialized Straightening
Shaped metal (non‑round sections) suffers from combined defects: camber (bending in multiple planes), torsion (axial twist), and cross‑sectional distortion. Standard round‑bar straighteners cannot correct these without damaging edges, rounding corners, or marring flat faces.
Our Solution – Precision Profile Straightening
Feature | Benefit |
Contoured, independently adjustable rolls | Custom‑machined to match the exact section – pressure applied only where needed |
Multi‑plane correction | Horizontal rolls fix camber; vertical rolls fix bow; twist station eliminates rotation – all in one pass |
Closed‑loop laser feedback | Real‑time straightness verification; auto‑adjusts for material variations |
Surface‑protective coatings | Polyurethane, nylon, or polished steel – no scratching, no galling |
Quick‑change tooling | Switch between shapes (square, hex, channel) in under 10 minutes |
Shapes & Typical Results
Profile | Size Range | Achievable Straightness |
Square / rectangular bar/tube | 6–200 mm | ≤0.2 mm/m |
Hexagonal bar | 8–50 mm AF | ≤0.25 mm/m |
Channel / angle | Up to 150 mm | ≤0.3 mm/m |
Custom extrusion | Variable | ≤0.3 mm/m |
Materials Processed
Carbon steel, alloy steel, stainless steel
