• Phosphate degreasing.
This includes cleaning and subsequent multi-metal phosphate dipping to increase paint adherence and resistance.
• Net water cleaning.
• Demineralized water cleaning.
• Rinse pieces to neutralize phosphates and degrease.
• Dry water.
The piece goes through a drying tunnel at high temperature (150º) to eliminate water and humidity traces.
• Electrostatic paint.
This includes the use of automated equipment to apply polyester powder paint.
• Polymerization furnace.
Paint is polymerized at 200ºC to ensure perfect adherence before being hardened by means of a controlled, calibrated layer (ranging between 80 to 120 microns).
All processes are automated.
• Standard colors: green and white
• We have a large color portfolio
on request, as shown in RAL chart.
• Degreasing of parts.
Galvanizing only occurs when material surfaces are chemically cleaned; to ensure that, phosphoric acid is used.
Hydrochloric acid dipping.
Water rinsing after acid treatment.
Salt dipping to favor zinc adherence onto the pieces.
Pieces are hot dipped in zinc at a temperature of 450º. Immersion in melted zinc causes a diffusion reaction between zinc and steel, favoring formation of the different layers. When the pieces are extracted the layers move to the outside, resulting in excellent corrosion resistance.
Hot galvanizing complies with the UNE EN ISO 1461:2009 standard.
