QRC

STAUFF manufacture QRCs for the majority of the World’s leading construction and agricultural machinery

companies, sold either directly or through third party distribution companies.

As standard, STAUFF QRCs are manufactured from carbon steel which is then zinc nickel plated resulting in a

minimum of 7 times increased corrosion resistance when compared to the more commonly used trivalent chromium

plating.

Please contact your local sales team for the complete range of products available and the options in stainless steel.

• ELV compliant according to 2000/53/EC (End of Life Vehicles Directive)

• REACH compliant according to 1907/2006/EC (Registration, Evaluation, Authorisation and Restriction of Chemicals)

• RoHS compliant according to 2002/95/EC (Restrictions of the Use of Hazardous Substances)
