Stark Coatings

staltec

For us, coatings are not just a layer. They are a strategy.

STARK Coatings are engineered to extend the life of components, reduce maintenance and improve performance across the harshest industrial environments.

Our surface solutions are developed with a precise understanding of wear mechanisms, thermal loads, corrosion behavior and mechanical stress - and are applied using the most advanced thermal spray, cladding and special technologies available.

Industries
we serve

STARK Coatings are trusted in industries where failure is not an option. We design each coating system based on operating conditions, repairability and life-cycle cost. Find out how our coatings can serve your industry.

Steel & Aluminum

Our coatings are specifically designed for:

  • Steel: Pot rolls, snouts, arms, furnace rolls, top rolls, process rolls, hot and cold rolling mill rolls
  • Aluminum: table rolls, process rolls, extrusion tooling

Benefits

  • Reduced roll change frequency
  • Improved strip quality
  • Longer service intervals under extreme temperatures and molten metal exposure
  • Coated surfaces with anti-stick and high wear resistance

Defense & Naval

We apply special techniques and systems for the military and naval-grade conditions.

  • Forging and extrusion tooling
  • High-performance components
  • Protective coatings for marine hydraulic and mechanical systems

These applications require coatings that endure:

  • High load cycles
  • Saltwater corrosion
  • Explosive shock and fatigue

Mining & Agriculture

We provide dense coatings that resist abrasion, impact and slurry erosion - tailored to open-pit and underground mining operations.

  • Pump components
  • Pelletizing rolls
  • Hydraulic rods
  • Classifier roller and conveyor belt drum bearing seat
  • Crusher parts and screens
  • Wear plates and liners

Textile & Paper

Our coatings increase resistance to abrasion, steam exposure and aggressive cycles, improving paper surface finish and reducing downtime.

  • Glue applicator rolls
  • Calendar rolls
  • Corrugator rolls
  • Feed rolls among others

Coating
Technologies

1. Thermal Spray

HVOF & Cold Spray:

High-velocity coatings with exceptional density, hardness and bond strength. Ideal for:

  • WC-Family, CrC-Family, Tribaloy, Stellite, Inconel-based systems
  • Wear, corrosion and fatigue protection

Plasma Spray

A versatile thermal spray technique producing oxide-resistant, tough coatings for high-temperature and chemically aggressive environments. Used for:

  • Ceramic coatings
  • Abradable and thermal barriers
  • Bond coats for multi-layer systems

Arc & Flame Spray

Cost-effective for large-area protection and dimensional rebuild:

  • Zinc, aluminum, steel wires
  • Field repairs and structural elements

2. Welding Technologies

Laser Cladding

A high-precision fusion process where a focused laser beam is used to apply a metallurgically bonded layer of material. Laser cladding allows:

  • Controlled heat input and minimal dilution
  • Complex geometries and localized repairs
  • Application of nickel, cobalt and carbide-reinforced alloys

PTA (Plasma Transferred Arc)

Used for heavy-duty rebuild and surface hardening:

  • High metallurgical bonding
  • Cobalt- and nickel-based wear-resistant overlays

3. Sealant & Hybrid Systems

STARK Sealers & Hybrid Systems

We apply special polymeric or ceramic sealers to:

  • Close porosity
  • Prevent corrosion propagation
  • Enhance performance in wet or chemically aggressive environments

STARK Coating Stack Engineering

Our in-house developed multi-layer strategies allow:

  • Wear + corrosion + anti-stick in one system
  • Optimized thermal behavior
  • Integration of diffusion layers and others for superior bonding and surface hardening
