Segments
On-site services, workshop services and surface engineering for demanding industrial equipment
Industrial equipment operates under very different conditions depending on the process.
A paper machine dryer cylinder, a steel mill roll, a hydropower turbine component and a food processing drum may have little in common at first sight. But from a maintenance and surface engineering perspective, they often face many of the same challenges:
Wear. Corrosion. Erosion. Damaged surfaces. Dimensional changes. Vibration. Contamination. Difficult-to-maintain large components.
PR Rolls provides specialised on-site services, workshop services and surface engineering solutions for critical industrial equipment across a wide range of industries.
Our roots are in the pulp, paper and board industries, where we have developed extensive expertise in machining, grinding, coating, balancing and maintaining large production-critical components.
Today, the same expertise, technologies and problem-solving approach are applied across other process and manufacturing industries.
Our capabilities include:
- On-site machining
- Grinding and precision finishing
- Industrial coatings and surface engineering
- Thermal spray coatings
- On-site and workshop component refurbishment
- Dynamic and field balancing
- Measurement and alignment
- Dimensional restoration
- Maintenance of large industrial components
- Application-specific solutions for production-critical equipment
The industry may change. The objective remains the same: restore, protect and improve critical equipment while minimising production disruption.
Industrial Services Built Around the Application
Different industries – similar maintenance challenges
PR Rolls does not approach industrial maintenance by offering the same predefined service to every customer.
The appropriate solution depends on the component, process and operating environment.
A component may require intervention because it has become:
- Worn
- Corroded
- Eroded
- Damaged
- Out of round
- Dimensionally incorrect
- Misaligned
- Unbalanced
- Contaminated
- Difficult to clean
- Unable to provide the required friction or release
- No longer suitable for changed production requirements
The solution may involve machining.
It may require a new functional coating.
It may require mechanical refurbishment, grinding and balancing.
Or the most effective solution may be to perform several operations as one coordinated project.
PR Rolls therefore starts with the industrial problem and component condition, then determines the appropriate combination of technologies and services.

On-Site Services Across Industries
When moving the component does not make sense
Large industrial components are often expensive, difficult or impractical to remove from the machine.
PR Rolls specialises in bringing machining, coating, measurement and balancing capabilities directly to industrial production sites.
On-site services can include:
- Grinding
- Turning
- Milling
- Line boring
- Drilling
- Grooving
- Honing and finishing
- Industrial coating
- Brush plating
- Measurement and alignment
- Field balancing
On-site execution can reduce:
- Dismantling
- Transportation
- Crane requirements
- Maintenance time
- Production downtime
This approach is particularly valuable for large, fixed and production-critical industrial equipment.
Workshop Services Across Industries
When the component can be brought to PR Rolls
Not every maintenance project should be performed on-site.
When a component can be efficiently removed and transported, PR Rolls' workshop provides a controlled environment for more comprehensive refurbishment.
Workshop capabilities include:
- Inspection and condition assessment
- Mechanical maintenance
- Precision machining
- Grinding
- Industrial coating
- Surface restoration
- Precision finishing
- Dynamic balancing
Suitable components can range from industrial rolls and cylinders to pumps, hydraulic components, valves, moulds, tools and other industrial machine components.
This gives customers two complementary service routes:
Large or fixed component → PR Rolls comes to the equipment
Removable component → Equipment comes to PR Rolls
Industrial Coatings & Surface Engineering
Engineer the surface around the operating environment
Across industries, many component failures begin at the surface.
Wear, corrosion, erosion, adhesion, insufficient friction and chemical attack can gradually reduce component performance.
PR Rolls provides functional surface technologies designed around different requirements, including:
- Wear resistance
- Corrosion resistance
- Chemical resistance
- Release and non-stick performance
- Controlled friction and traction
- Reduced contamination
- Dimensional restoration
Technologies include thermal spray coatings, carbide coatings, polymer-based solutions and selective brush plating for suitable applications.
The appropriate solution is selected according to:
Component → Substrate → Operating environment → Failure mechanism → Required surface functionality
Repair, Refurbish or Replace?
Extend the life of existing industrial equipment where appropriate
A worn or damaged industrial component does not automatically need to be replaced.
Depending on its structural and mechanical condition, PR Rolls can evaluate whether the component can be:
Repaired – correct a local defect.
Machined – restore dimensions or geometry.
Recoated – renew or change the functional surface.
Refurbished – combine several maintenance operations.
Modernised – modify an existing component for changed production requirements.
Replaced – when continued refurbishment is no longer technically appropriate.
This lifecycle approach is relevant across industries.
The component may be a paper machine cylinder, steel-industry roll, pump component or power-generation shaft – the decision should be based on condition, function and future operating requirements.
One Industrial Service Partner – Multiple Technologies
PR Rolls combines capabilities that are often sourced from several different specialists:
On-site machining + Workshop refurbishment + Grinding + Surface engineering + Coating + Measurement + Alignment + Balancing
This combination allows the maintenance solution to be built around the component rather than around one individual service.
Our experience originates in some of the most demanding continuous-production environments in the pulp, paper and board industries. Today, these capabilities are applied to production-critical equipment across a growing range of industrial segments.
Different industries. Different equipment. The same objective: restore critical components efficiently and keep production running.
