Chrome Plated Working Roll for 1450 mm Tension Levelers in Galvanizing Lines
On a 1450 mm galvanizing line the working roll is a consumable that decides strip flatness and surface finish. Working together with the intermediate and back up rolls it resists deflection under high load, which is what keeps flatness deviation and surface defects out of the finished galvanized coil.
- Built for 1450 mm tension levelers in galvanizing lines
- Hard chrome plated contact surface
- Deep hardened layer for repeat regrinding
- Made to the roll drawing of your cassette
Key Benefits
Why the roll specification pays back on a coating line.
Flatness And Finish Held Together
Because the roll contacts the strip directly, its geometry and surface decide flatness accuracy and surface finish on the galvanized coil.
Fewer Roll Changes
Wear resistance and extended service life lower the roll replacement frequency, which is the main hidden cost on a continuous line.
Stable Coating Uniformity
Consistent roll condition keeps the leveling result stable over a campaign, so coating uniformity does not drift.
Where It Is Used
Where this roll is fitted.
- 1450 mm continuous galvanizing lines
- Tension leveler cassettes on coating lines
- Strip leveling for appliance and construction sheet
- Lines processing carbon steel, stainless and aluminum strip
Who It Is For
- Galvanizing line maintenance planners
- Plants standardising roll spares on 1450 mm lines
- Buyers replacing imported consumable rolls
- Service centres operating leveler cassettes
Problems It Solves
- Strip flatness deviation caused by roll deformation
- Surface defects printed by worn or damaged rolls
- High equipment failure rate from roll related stoppages
- Frequent roll replacement raising comprehensive production cost
Technical Features

Cooperates With Intermediate And Back Up Rolls
The roll is dimensioned to work as part of the cassette so deflection and structural deformation are avoided during high load operation.
Chrome Plated Surface
Chrome plating around 0.05 mm gives the wear resistant low friction contact face against the strip.
Dimensional Accuracy To Drawing
Precise dimensional accuracy is what allows the roll to be dropped into an existing 1450 mm cassette without adjustment.
Specifications
Dimensions follow your cassette drawing. Values below describe the standard build for 1450 mm line service.
| Line Width | 1450 mm tension leveler |
|---|---|
| Application | Galvanizing line strip leveling |
| Surface Treatment | Hard chrome plating, around 0.05 mm |
| Hardened Layer | Around 5 mm deep |
| Material | High quality carbon steel or stainless steel |
| Strip Materials Served | Carbon steel, stainless steel, aluminum |
| Dimensions | Made to customer cassette drawing |
Materials
- High quality carbon steel roll body
- Stainless steel option for wet line areas
- Hard chrome plated working surface
Manufacturing Process
Drawing Confirmation
Cassette position, diameter, barrel and neck dimensions are confirmed against your drawing or sample.
Machining And Heat Treatment
The roll is turned, then heat treated to build the hardened layer.
Grinding
The barrel is ground to profile and roughness before plating.
Plating And Finish Grinding
Hard chrome is deposited and the roll is finish ground concentric to the necks.
Quality Control
- Hardness and hardened layer verification
- Diameter, barrel and neck dimensional inspection
- Plating thickness measurement
- Runout and straightness check before packing
Customization Options
- Roll diameter and barrel length for your 1450 mm cassette
- Neck detail matched to existing bearing housings
- Plating thickness adjusted to strip material
- Set marking per cassette position
Use Guide
- Fit rolls as a matched set to keep diameters inside cassette tolerance
- Regrind before the chrome breaks through
- Inspect the strip surface for repeat marks to catch roll damage early
- Store rolls protected and horizontally supported
How It Compares
Against other roll options on a 1450 mm line.
| Unplated hardened rolls | Chrome plating lowers friction against zinc coated strip and resists pickup that would mark the surface. |
|---|---|
| Original equipment spare rolls | Made to the same drawing with documented hardness and plating, usually at a shorter lead time. |
| Reground worn rolls beyond limit | A new roll restores the cassette diameter band instead of running an out of tolerance set. |

Read MoreChrome Plated Working Roll for 1450 mm Tension Leveler FAQ
Does this fit our 1450 mm leveler?
It is built for 1450 mm tension levelers in galvanizing lines, but the exact fit depends on your cassette drawing. Send the drawing or a sample and we confirm before production.
What is the chrome plating thickness?
Around 0.05 mm, then finish ground so the plated surface is concentric with the roll necks.
Which strip materials can it level?
Carbon steel, stainless steel and aluminum strip within the range your leveler was designed for.
Can it be reground?
Yes, the hardened layer is deep enough for repeated regrinds. Regrind before the chrome layer wears through.
Do you supply the complete cassette?
Yes. Working rolls, intermediate rolls, back up rolls and cassettes are all made here so the set stays consistent.
What is needed for a quotation?
Roll drawing or sample, cassette position, quantity per set and how many sets per year.
