Warranty and Product Quality

Orsi provides a 3-year warranty on cast metal parts, underscoring the durability and reliability of their steel cast components.

Anti-Corrosion Treatment Processes

• Shot Blasting: Surface preparation using SA granulation at 2.5 mm diameter.
• Primer Application: Zinc phosphate epoxy powder primer with 60-80 μm thickness.
• Finishing Coats: Extra polyurethane powder coating resistant to UV rays, polymerized at 180°C for 20 minutes, with a final dry thickness of 120-160 μm.

These treatments comply with C5-I class standards (DIN55633 and DIN EN ISO 12944-6), ensuring high corrosion resistance including 2000 hours of salt spray exposure. Mechanical and hydraulic components receive additional liquid anti-corrosive treatment.

Advanced Coating Options

• Epoxy bi-component zinc CT90 primer.
• Expo primer CT113 in grey RAL 7035.
• Extra bi-component polyurethane enamel with UV resistance, available in dry thicknesses of 180-200 μm or 350-400 μm.
