This ultimately depends on the grade of sterile clean room you have in your facility.

Generally, Aseptic cleanrooms require marine grade 316 stainless steel which withstands corrosion and does not rust therefore not contaminating the air.

However, in certain clean environments that are not sensitive to contamination of air with microorganisms, you can use the standard Roll Pallets or Cage Stillages that we supply.

These units are made from mild steel that are electro zinc plated so the chance still exists that they could someday rust especially if they are at a coastal location where the air is saltier. This is why marine grade 316 stainless steel is the best option for an aseptic environment.
