Chrome Plated Work Rolls for 1450 mm Tension Levelers in Galvanizing Lines
Work rolls are the primary contact elements between the leveler and the strip, and they support the backup or intermediate rolls against deflection under rolling force. Any deviation in roll geometry or surface integrity shows up immediately as flatness, thickness or surface problems on the finished coil.
- Diameter range 9 mm to 68 mm
- Hardened layer around 5 mm
- Chrome plating around 0.05 mm

Key Benefits
Why roll geometry is the control point.
Direct Effect On Product Quality
Because the work roll contacts the strip, its geometry and surface integrity decide flatness, thickness uniformity and surface quality on the finished product.
Deflection Prevented Under Load
The roll supports the backup or intermediate rolls, preventing deflection and deformation under immense rolling forces.
Output Efficiency Of The Line
Work roll performance is directly linked to the output efficiency of the entire plate and strip production line.
Where It Is Used
Where they run.
- 1450 mm galvanizing line tension levelers
- Leveler cassettes on coating lines
- Strip processing lines for automotive and appliance sheet
- Multi roll cassettes across the 9-68 mm diameter band
Who It Is For
- Galvanizing line maintenance teams
- Plants standardising work roll supply
- Machine builders assembling cassettes
- Buyers replacing rolls across several diameters
Problems It Solves
- Flatness deviation from roll geometry error
- Thickness variation across the strip
- Surface defects from damaged roll surfaces
- Deflection under high rolling force
Technical Features
Roll specification.
Wide Diameter Coverage
Rolls are produced across 9 mm to 68 mm, covering the diameters used in multi roll leveler cassettes.
Deep Hardened Layer
A hardened layer of around 5 mm supports repeated regrinding through the roll life.
Chrome Plated Surface
Plating of around 0.05 mm gives the wear resistant low friction contact surface, with plating builds up to around 0.3 mm available for specific duties.
Specifications
Barrel and neck dimensions follow your cassette drawing.
| Line Width | 1450 mm tension leveler |
|---|---|
| Diameter Range | 9-68 mm |

| Thickness Reference | Strip up to around 8.0 mm depending on configuration |
| Function | Primary contact element supporting backup and intermediate rolls |
| Dimensions | Made to cassette drawing |
Materials
- Alloy steel roll body
- Deep hardened working layer
- Hard chrome plated surface
Manufacturing Process
Drawing Confirmation
Diameter, barrel and neck detail are taken from the cassette drawing or a sample.
Machining
Roll bodies are turned with heat treatment and plating allowance.
Heat Treatment
The hardened layer is developed to depth with uniform hardness.
Grinding And Plating
Barrels are ground, chrome plated and finish ground concentric to the necks.
Quality Control
- Hardness and layer depth testing
- Geometry inspection of diameter and straightness
- Plating thickness measurement
- Runout verification before packing
Customization Options
- Any diameter across 9-68 mm
- Plating thickness for the strip material
- Barrel length and neck to your cassette
- Matched sets marked by position
Use Guide
- Fit rolls as a matched set within the cassette
- Regrind before the plating wears through
- Watch strip surface for repeat marks
- Store rolls protected and horizontally supported
How It Compares
Specification choices.
| Standard plating thickness | Around 0.05 mm suits most leveling duty while heavier builds are available where wear is severe. |
|---|---|
| Unplated rolls | Chrome plating lowers friction against coated strip and resists pickup. |
| Single diameter supply | Covering 9-68 mm from one supplier keeps hardness and tolerance consistent across cassette positions. |

Read MoreWork Roll for 1450 mm Tension Leveler FAQ
What diameters do you produce?
From 9 mm to 68 mm, made to your cassette drawing rather than a fixed catalogue.
How thick is the chrome layer?
Around 0.05 mm as standard, with heavier builds up to around 0.3 mm available where the duty requires it.
Why does roll geometry matter so much?
The work roll is the primary contact element with the strip. Any deviation in geometry or surface integrity compromises flatness, thickness uniformity and surface quality straight away.
Can the rolls be reground?
Yes, the hardened layer of around 5 mm supports repeated regrinding. Regrind before the plating is worn through.
Do you supply the full cassette?
Yes, work rolls, intermediate rolls, back up rolls and cassettes are all produced here.
What do you need to quote?
Cassette drawing or sample roll, diameter and quantity per set, strip material and annual usage.
