Extend the service life of critical production equipment
PR Rolls provides advanced on-site coating services for rolls, cylinders and industrial machinery operating in demanding production environments.

Using proprietary coating technologies, thermal spraying expertise and decades of experience in industrial maintenance, we help customers improve wear resistance, corrosion protection, cleanliness, release properties and operational reliability.

Unlike traditional workshop-based coating solutions, PR Rolls performs coating directly at the customer’s premises whenever possible. This significantly reduces downtime, eliminates unnecessary transport and allows maintenance work to be completed during planned shutdowns.

Our coating solutions are used by customers in:

  • Paper mills
  • Board mills
  • Tissue mills
  • Pulp mills
  • Steel mills
  • Power plants
  • Food industry
  • Marine industry
  • Process industries

The objective is simple:

Longer component life, lower maintenance costs and more reliable production.

PR Rolls already highlights that on-site coating is one of the fastest and most cost-effective ways to extend roll life and ensure trouble-free operation.

What Is Industrial Coating?

Industrial coating is a process where a protective surface layer is applied to a component in order to improve its performance and durability.

Modern coating technologies can significantly improve:

  • Wear resistance
  • Corrosion resistance
  • Release properties
  • Friction characteristics
  • Surface hardness
  • Surface cleanliness
  • Chemical resistance
  • Service life

Thermal spray coatings are widely used in the pulp, paper and process industries because they can protect components from wear, abrasion, corrosion and aggressive operating conditions while extending equipment lifetime.


Why Choose On-Site Coating?

For large industrial components, transporting equipment to a workshop is often expensive and time-consuming.

On-site coating allows maintenance work to be performed directly where the equipment operates.

Benefits include:

  • Reduced downtime
  • Lower transportation costs
  • Less dismantling
  • Faster maintenance shutdowns
  • Reduced production losses
  • Lower lifecycle costs
  • Faster return to operation

Many industrial coating providers now emphasize on-site thermal spraying specifically because it minimizes downtime and total maintenance costs.


Problems Solved by Industrial Coatings

Industrial environments expose machinery to continuous wear and harsh operating conditions.

Typical challenges include:

Wear and Abrasion
Continuous contact, friction and mechanical loading gradually wear down surfaces.

Coatings can provide significantly higher wear resistance than the original substrate and extend component life.

Corrosion
Moisture, chemicals, process liquids and aggressive environments cause corrosion that reduces component lifetime.

Specialized coatings can improve corrosion resistance and protect critical equipment.

Build-up and Contamination
Paper mills frequently struggle with:

  • Resin deposits
  • Stickies
  • Dirt accumulation
  • Process contamination

Advanced surface technologies can reduce build-up and improve cleanliness.

Release Problems
Poor release characteristics affect paper quality and machine runnability.

PR Rolls' fluoroplastic composite coatings were specifically developed to improve paper release from cylinders.

Frequent Roll Replacement
Coating existing rolls is often significantly more economical than purchasing new components.

PR Rolls already positions coating as an alternative to replacement, especially with TecnoDiamond and Tecno Diamond FS.


Components We Coat
PR Rolls provides coating solutions for a wide range of industrial components.

Typical applications include:

  • Paper and Board Machines
  • Drying cylinders
  • Yankee cylinders
  • MG cylinders
  • Calender rolls
  • Press rolls
  • Guide rolls
  • Suction rolls
  • Vacuum rolls
  • Lead rolls
  • Reel drums
  • Winder drums

These are among the most commonly coated components in the pulp and paper industry.

Power Generation Equipment

  • Shafts
  • Turbine components
  • Bearing journals
  • Flanges
  • Heat exchanger components

Steel Industry Equipment

  • Rollers
  • Guide systems
    Bearing surfaces
    Process equipment exposed to wear

Food Industry Equipment

  • Drum dryers
  • Drying cylinders
  • Food processing surfaces

PR Rolls recently expanded its coating expertise into food-industry drum dryer applications through Tecno Diamond FS.

The main products in our coating range are our long-life carbide coatings and our fluoroplastic carbide composite coatings that make it easy to remove the paper from the cylinder. We have been actively involved in developing new coating materials and methods that can be completed on site. The newest of these is our carbide and nano fluoride composite coating for cylinders. Its operating characteristics are better than those of the furnace-manufactured fluoroplastic coating known as Teflon. No other company in the world has a corresponding coating – we are the only company to have created a coating that can be applied on site.                  

  • TecnoClean and TecnoClean Cera Hybrid composite coatings prevent dirt and sticky build-up
  • TecnoGrip anti-slip coating                          
  • TecnoGuide coating prevents corrosion and dirt build-up                              
  • TecnoDiamond hard coating                       
  • TecnoMicro coating prevents dirt build-up

Cylinder and roll coatings applied on site are the easiest, quickest and most cost-effective way for you to prolong the life of your rolls and ensure their trouble-free operation. Our coating technology and expertise allow paper mills to make considerable savings in both operating costs and investments. Faultlessly functioning machines ensure uninterrupted production and excellent paper quality. Our coatings are wear-resistant and, given the right circumstances, can extend the roll’s operating life many times over.
