About chemical resistance

Chemical resistance of wheels and castors

Read about our chemical resistance ratings to find out which wheel or castor will best suit your application.

The castors and wheels we make have worked well for many years in many uses and places around the world. However, sometimes you may want to apply them in places more corrosive than the usual residential, commercial or industrial environment. In the table below, we lay out what can be expected from our castors when exposed to some of the more severe chemicals used.

For castors that are resistant to corrosion or extreme temperatures, see our range of corrosion resistant castors, and our high and low temperature castors.

If you are planning to use our castors in severe conditions, our team will be happy to help you choose the right castor for the job.

Powder-coated

We have powder-coated castors specially designed for corrosive environments (particularly shower chair applications). Our powder coated castors are first zinc plated and then powder-coated so as to better resist corrosion from substances such as alkaline soaps and other cleaning agents. The castors have stainless steel bottom races and twin ball races with stainless steel balls covered by a diaphragm shroud to stop water entering from above (the top race is zinc plated only). The castors are powder coated in Interpon colour "Anodic Natural Matte". The wheels are available with a plain PBT (corrosion free) bush or a stainless steel precision bearing. Thread guards prevent the build-up of hair and lint.

Powder-coated range

Stainless steel

Our stainless steel castors are the premium castors for corrosive environments. With a wide range of styles and load capacities available, we have castors to suit almost all corrosive applications. All castors in our stainless steel range are completely corrosionfree with all metal components made from stainless steel.
