Roll Coaters For Galvanizing and Colour Coating Lines
Finishing equipment that applies paint or passivation solution evenly across the strip surface.
Coating weight that drifts across the width or between coils shows up on the finished panel. Roll pressure has to be measured, not guessed.
Roll Coaters We Supply
Horizontal, vertical and winding configurations for galvanizing and colour coating lines.
Roll Coating Machine for Galvanizing and Color Coating Lines
Horizontal, vertical and winding type coaters for 450-2200 mm strip at 70-260 m/min.

Passivation Roll Coater
Applies trivalent chrome passivation film to protect strip surfaces against corrosion.

Design points.
Measured Roll Pressure
Pressure sensors provide roll pressure feedback and four load cells are configured for the passivation coating rolls.
Quick Opening Top Head
The top side coating head has a synchronised quick opening mechanism for access, cleaning and colour change.
Off Strip Applicator Clearance
Front and back applicator rolls run with a slight off strip contact, which improves coating application and protects the surface.
Application Scenarios
Configurations by line.
Galvanizing Lines
Vertical type coaters applying trivalent chrome passivation for corrosion protection.
Colour Coating Lines
Horizontal, vertical or winding type for primer and finish coat stations.
Wide Strip Processing
Strip up to 2200 mm wide and 3 mm thick at up to 260 m/min.
Roll Coaters Buying Questions
Which configuration suits a galvanizing line?
The vertical type is generally used in galvanizing lines. All three types, horizontal, vertical and winding, are suitable for colour coating lines.
What strip range is covered?
Width 450-2200 mm, thickness 0.15-3 mm and operating speed 70-260 m/min.
How is coating pressure controlled?
Hydraulic cylinders drive the front coating head with pressure sensor feedback, and four load cells are configured on the passivation coating rolls.
What coating does the passivation coater apply?
A thin film of a trivalent chrome compound on the plate surface to protect it against corrosion.
Do you supply the coating rolls afterwards?
Yes, applicator and pick up rolls can be supplied as spares to the same drawing.
Can it be integrated with our paint supply system?
Yes. Tell us the chemistry and supply arrangement and we design the interface accordingly.
