Belzona® Makes Grit Trucks Fit For The Winter



General Industry (GIND)



Solids Handling Machinery (SHM)


Customer Location:

Local Authority Switzerland


Application Date:

2003 and October 2009


Application Situation:

Screw auger from a road gritting truck



Auger screws from salt gritting trucks get worn due to the abrasive effect of the salt grit and corrosion resulting in shorter than desired life expectancies.



Belzona® 1321 (Ceramic S-Metal)





Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet SHM-14. Two coats of Belzona® 1321 were applied to the grit blasted steel substrate.


Belzona Facts:

The pictures show the coating of a new screw auger. This particular application resulted through the success in 2003 of a smaller version of this auger screw, similarly protected with Belzona® 1321. After 6 years the screw was still in service and in good condition and exceeding the customer’s expectation.
