How to choose commercial food storage and shelving

Quick answer. Standardise everything on gastronorm, then pick shelving by area: stainless for cold rooms and wet zones, wire or chrome for dry stores, polymer or antimicrobial for high-care. Add sealable GN containers with clear date labels and lay the room out so FIFO and raw-below-cooked are the easy option, and most storage and hygiene problems solve themselves.

Storage and shelving decide how fast your team moves, how much stock you waste and how a hygiene inspection goes, so it is worth planning rather than buying whatever fits the gap. Get the module size, the materials and the layout right once and everything after that just slots in.

The questions to ask before you buy

Should I standardise everything on gastronorm?

Yes, and it is the single most useful decision you will make. Gastronorm (GN) is a fixed international size system built around the 1/1 pan at 530 by 325mm, then divided down (1/2, 1/3, 1/6, 1/9) and up in depth (65, 100, 150, 200mm). When your containers, prep pans, fridge runners, combi trays, bain marie wells and shelf pitch are all GN, a pan of diced onions moves from cold room to prep bench to service line to blast chiller without ever being decanted. Buy odd tub sizes and you lose that, plus you waste fridge space around the gaps.

Which shelving material belongs in each area?

Match the material to the environment, not to a single bulk order. Stainless steel for wet, cold and heavy areas (cold rooms, wash-up, anywhere hosed down) because it shrugs off moisture and takes weight. Chrome or epoxy-coated wire for dry stores and general back of house, as it is cheaper, lets air circulate and is easy to reconfigure. Polymer or polypropylene shelving where you want to dismantle and dishwash the shelves themselves. Antimicrobial-treated shelving (polymer with a built-in biocide, or antimicrobial-coated wire) for high-care and ready-to-eat zones where you want an extra barrier against bacterial growth on the surface.

How much weight will each shelf actually carry?

Check the per-shelf load rating before you buy, not the marketing figure for the whole bay. A case of tinned tomatoes or a full 1/1 by 200mm GN of stock is heavier than people expect, and dry stores get overloaded fast. Look for the rating stamped per shelf (commonly 150 to 350kg evenly distributed on good commercial bays) and site the heavy, low-turnover stock on the lower shelves. Overloaded domestic or light-duty shelving bows, then tips, and that is how you lose a pallet of stock and possibly a member of staff.

Do I need adjustable shelving?

Almost always, yes. Fixed-pitch shelving wastes the vertical space above short items and cannot cope when your product mix changes. Look for shelves that reset on a 25mm or so increment without tools, so you can retune a bay in minutes when you switch supplier or seasonal range. In cold rooms especially, adjustable posts let you run tall GN containers on one run and flat trays on the next, squeezing far more usable capacity out of the same footprint.

How do I lay out storage so FIFO and raw-below-cooked actually happen?

Design the layout so the correct behaviour is the easy behaviour. FIFO (first in, first out) only works if staff can load new stock from the back and pick from the front, so leave access or use gravity/rotation racking rather than deep static shelves people load from the front. For raw below cooked, the rule is raw meat and unwashed produce always sit on shelves beneath ready-to-eat and cooked food, so any drip cannot contaminate what is eaten as is. Set fixed zones and label them, because a system that depends on everyone remembering will fail on a busy Friday.

Where does vacuum packing fit in?

Vacuum packing (and sous vide prep) earns its place when you are batch-prepping, protecting expensive proteins, or trying to cut waste from short-life items. Removing air slows the oxidation and aerobic bacterial growth that spoil food, so correctly chilled vac-packed portions can hold noticeably longer than the same food loosely wrapped, and they store flat and stackable. It is not a substitute for temperature control or for your date-code discipline, and anything vacuum packed for extended chilled storage needs a documented process and often an EHO-agreed shelf life, so treat it as a tool within your HACCP plan rather than a shortcut around it.

The main types, and who each suits

Stainless steel shelving (solid or perforated)

Cold rooms, wash-up areas, wet prep and anywhere that gets hosed or sees constant moisture and weight. The default for high-care and cold storage. Perforated or slotted versions improve air circulation around chilled stock; solid shelves are easier to wipe for spillage-prone zones.

Chrome and epoxy-coated wire shelving

Dry stores, ambient back of house and general reconfigurable racking. Airflow through the wire keeps stock dry, it is quick to adjust and it is the sensible value choice away from wet areas. Choose epoxy or powder-coated finishes for chillers and humid corners where bare chrome would eventually pit.

Polymer / polypropylene shelving

Cold rooms, high-care and any area where you want to lift the shelves out and put them through the dishwasher. Fully corrosion-proof, warm to the touch and easy to deep clean, often sold with antimicrobial versions for ready-to-eat zones.

Gastronorm containers and lids (food-grade, sealable)

Standardised prep, decanting and cold storage that interchanges across fridges, prep counters and combi ovens. Clear polycarbonate for visibility, food-grade and sealable to lock out cross-contamination and odours, sized 1/1 down to 1/9 with matching lids for airtight, stackable storage and clear date labelling.

Mobile / adjustable bay systems and cold room kits

Cold rooms and busy stores that need to flex. Adjustable posts retune shelf pitch in minutes, and castored bays let you wheel a whole run out to clean the floor beneath, which is where audits are usually lost. Specify the layout to keep clear walkways and nothing stored directly on the floor.
