Rivet Coatings

Rivet coating is a fundamental part of the riveting process and needs careful consideration before a selection is made.The standard coatings shown in the table below are used in the majority of applications to protect steel self-pierce rivets when applied to steel, aluminium or other products. Coatings are specified generally for corrosion protection but in some cases may be required for decorative purposes.

Anti-corrosion performance associated with low thicknesses has always been a determining choice for the automotive industry. Its requirements regarding anti-corrosion are met with coating weights ranging from 24g/m2 to 36g/m2. This low thickness enables most threaded fasteners to be coated easily. Automotive manufacturers have very specific test methods, particularly cyclic corrosion tests (ACT, SAE/USCAR) and salt spray tests (IS0 9227/ASTM B117).

Commonly Used Coating ;

Ni-Cr

Zinc Silver Coated Steel

Zinc flake

Zinc/Tin Silver Aluminium

Organic on top o f Zinc  Silver or Black Food grade organic finish

Semi-decorative finishes

Painted Head

(on top of coating) Any RAL Colour Colour matched to pre-painted materials

Burnished Silver Used on Stainless Steel rivets for decorative or corrosion resistant

Applications…

New coatings that are compatible with an increasing number of applications and environmental conditions are being researched in our laboratories or as part of customer-specified programmes.

Coatings can be supplied free of hexavalent chrome (Chromium 6) as specified in the “End of Vehicle Life Directive – 2006.” Other specialised coatings are available.
