Short answer
Use shelving built for cold, wet conditions: epoxy-coated wire, polymer or stainless steel. Chrome wire shelving is made for dry storage and tends to rust in the constant humidity of a walk-in cooler or freezer. Open shelves also let cold air circulate around the product, which helps the unit hold temperature.
Epoxy-coated wire resists moisture at a moderate cost, but a chipped coating exposes steel that can rust. Polymer shelving resists rust, and on many systems the shelf mats lift out for washing. Stainless usually costs the most.
Measure the walk-in's interior and door opening before ordering, and leave space at the evaporator so shelves and product do not block its airflow.
Keep the bottom shelf high enough off the floor for the floor to be cleaned underneath. For heavy cases and sacks, a dunnage rack is sturdier than a low shelf.
