Stainless Steel Casters for Washdown, Marine & Corrosive Environments

Corrosion does not start at the wheel — it starts at the fork and the bearing. in washdown kitchens, pharma cleanrooms, and coastal plants, a zinc-plated caster rusts at the raceway until the swivel locks and the whole unit has to be scrapped. we build these casters from 304 and 316 stainless steel with full stainless ball bearings and raceways, so the swivel keeps turning through saline, steam, and chemical wash instead of seizing.

Grade choice is the decision that protects the order. SS304 handles standard food-prep, lab, and hospital washdown at lower cost. SS316 adds molybdenum for chloride resistance, which is what stops pitting corrosion in marine, coastal, and high-salinity service where 304 would eventually fail. matching the grade to the environment is the difference between a caster that lasts and a warranty return.

Wheel material then tunes the behaviour. PU treads roll non-marking and quiet for hospital and lab floors; nylon shrugs off humidity, steam, and chemicals; elastic rubber runs silent under lighter loads. the range covers 50–250 mm diameters and loads to 600 kg, in top-plate, threaded, and expanding-stem mounts, all to ANSI/ICWM and ISO 22883 requirements. for a distributor, that grade-and-wheel logic is exactly the advice your buyers need before they order.
