Auxiliary Roll Coating Specialists
Top Tier Auxiliary Rolls Coating Mills Solution
Tough coatings that help your mill rolls last longer and keep your line running.
Longer Roll Life - More hours between changes
Less Downtime - Fewer unplanned stops
Wear & Rust Proof - Handles heat and abrasion
Fast Turnaround - Planned around shutdowns
- All Auxiliary Roll Types
- Carbide, Ceramic & Metal Coatings
- Coating + Grinding In-House
- Quick Technical Support
WHY COAT YOUR ROLLS
Bare Steel Wears Fast.
Coated Rolls Last.
Auxiliary rolls face constant friction, heat, water and chemicals. Over time the surface wears, the strip slips and the roll must be changed. A hard coating protects the surface and keeps it working longer.
- Stops surface wear
- Keeps the right grip
- Fights rust and build-up
- Saves money

What industries benefit most from HVOF coatings?
Industries like aerospace, automotive, oil & gas, power generation, and marine greatly benefit from HVOF coatings due to their superior durability, corrosion resistance, and ability to handle harsh operating environments.
How does thermal spray coating compare to purchasing a brand-new roll?
Coating an existing roll core typically costs 30% to 50% of the replacement price for a new forged alloy roll. Furthermore, applied tungsten carbide or ceramic surfaces offer 2x to 4x longer operational wear life than un-coated OEM tool steel cores.
What is HVOF coating, and how does it work?
HVOF (High Velocity Oxygen Fuel) coating is a thermal spray process where fuel and oxygen create a high-velocity flame that melts and accelerates powder particles onto a substrate, forming a dense, durable coating.
Do you handle precision cylindrical grinding and superfinishing in-house?
All grinding, crowning, and finishing operations are conducted in-house on heavy-duty CNC cylindrical grinders fitted with diamond wheels. We hold strict dimensional tolerances, profile geometry, and continuous surface roughness across the entire roll face.
What surface roughness (Ra) tolerances can be achieved post-coating?
Depending on your process requirements, we can provide mirror finishes down to Ra < 0.05 µm (2 µin) for critical surface-sensitive strip processing, up to textured traction profiles of Ra 3.0–6.0 µm for high-grip bridle rolls.
What are your facility's maximum roll diameter, length, and weight capacities?
Our high-capacity lathes and robotic spray cells handle rolls up to 1,800 mm in diameter, 7,500 mm in total length, and individual workpieces weighing up to 12 metric tons.
