Choose Commercial Shelving That Fits Your Storage and Your Space
Shelving is the part of the kitchen that holds everything else. The right system keeps stock off the floor, makes ordering easier and helps the team find what they need quickly.
Use this guide to compare wire, polymer and solid shelving, choose the right type for dry storage, coolers and freezers, and plan the sizes, loads and extras before you buy.
Start With What You Store and Where
Walk through your storage areas and list what goes where: dry goods, cans, smallwares, paper, chemicals and cold stock. Different areas have different needs for cleaning, airflow and moisture.
Then measure the space, including the height, the depth and any pipes, vents or sprinklers that limit where shelves can go.
Best-Fit Operations
This guide is for any foodservice operation with dry, cold or frozen storage.
Which Type of Shelving?
Match the shelf to the area it sits in.
Wire shelving is open, which lets air move around stock. It is common in walk-ins and dry storage and is easy to clean. Polymer shelving resists moisture and rust and suits humid or wash-down areas. Solid and stainless steel shelves hold small items and spills, and suit prep areas. Mobile units sit on casters and move stock where you need it.
Many kitchens mix types: wire in the walk-in, polymer in wet areas, solid in dry storage and mobile units for the line.
Quick guide
- Wire: open, airy, easy to clean.
- Polymer: moisture and rust resistant.
- Solid or stainless: holds small items and spills.
- Mobile: moves with the work.

| Type | Best for | Strengths | Trade-offs |
|---|---|---|---|
| Wire | Walk-ins, dry storage | Airflow; easy to clean; good load capacity | Small items can fall through without liners |
| Polymer | Wet, humid and cold areas | Resists moisture and rust; easy to clean | Check the load rating for heavy items |
| Solid / stainless | Prep and dry storage | Holds small items; wipes down | Less airflow; can cost more |
| Mobile | Lines, prep and banquet | Moves stock and equipment | Casters and floor condition matter |
Shelving by Storage Area
Dry storage, coolers and freezers have different needs.
Dry storage should keep stock off the floor and allow airflow. Walk-in coolers and freezers need shelving that handles cold and moisture and allows air to circulate. Wet and wash areas need materials that stand up to water and chemicals.
Many local health authorities set minimum clearances for stock above the floor, and for the space around walls and ceilings. Check what applies to you.
Check for each area
- Moisture, temperature and cleaning needs.
- Minimum clearance from the floor and walls.
- Load and shelf depth for what you store.
| Area | Good fit | Consider |
|---|---|---|
| Dry storage | Wire, solid or stainless | Airflow, floor clearance and labelling |
| Walk-in cooler | Wire or polymer | Corrosion resistance and airflow |
| Walk-in freezer | Wire or polymer rated for freezers | Check the cold rating and the finish |
| Wet or wash area | Polymer or stainless | Water, chemicals and drainage |
| Prep and line | Solid, stainless or mobile | Reach, height and cleaning |
Size, Height and Load
Measure first. A shelf that does not fit costs more than one that is a little small.
Shelving is sold in standard lengths and depths. Measure the wall or floor space, and subtract anything that limits the space, such as pipes, vents and sprinkler heads. Check the load rating for each shelf and for the whole unit, and plan to put the heaviest items low.
Leave space between shelves for the tallest item you store, and for staff to reach safely.
Measure and check
- Length, depth and height of the space.
- The load per shelf and per unit.
- Clearance for sprinklers, vents and doors.
| Item | What to check | Why it matters |
|---|---|---|
| Footprint | Length and depth, including door swing | Shelving that blocks a door is unusable |
| Height | Ceiling, sprinklers and reach | Staff need to reach the top shelf safely |
| Load rating | Per shelf and per unit | Overloaded shelves can fail |
| Shelf spacing | Height of your tallest item | Wasted space or items that do not fit |
| Aisle width | Room for carts and people | A crowded room slows everything down |
Accessories, Casters and Safety
A few extras make shelving much more useful.
Dividers, wall mounts, liners, dunnage racks and labelling systems keep stock tidy. Casters turn shelves into mobile units, and brakes keep them still. Choose casters that suit the floor and the load.
Secure tall units to the wall or to each other where the manufacturer recommends it, especially in busy areas and where there may be seismic activity.
Consider adding
- Casters with brakes for mobile units.
- Liners for small items.
- Dunnage racks for heavy sacks and cases.
- Labels and a stock rotation system.
Common Mistakes to Avoid
Most shelving regrets come from skipping a measurement.
Not measuring first
Measure the space, including pipes and vents.
Ignoring the load
Check the load rating per shelf and per unit.
Using the wrong material
Wet, cold and dry areas need different shelves.
Stock on the floor
Keep stock off the floor, as your local rules require.
Blocking airflow
Packed shelves make coolers work harder.
Skipping casters or brakes
Mobile units need the right casters for the floor.
No labels or rotation
Shelving works best with a clear system.
Forgetting growth
Leave room for more stock.
Frequently Asked Questions
Short answers to the questions we hear most about commercial shelving.
Wire or polymer?
Wire suits walk-ins and dry storage. Polymer suits wet and humid areas. Check each product's rating.
How high should stock be off the floor?
Local health codes set the minimum, so check yours.
Can I use shelving in a freezer?
Yes, if it is rated for the cold. Ask or check the listing.
How much weight can a shelf hold?
It depends on the model. Check the load rating per shelf and per unit.
Do I need liners?
Liners help hold small items on open wire shelves.
Can a specialist help me plan?
Yes. Share your measurements and what you store, and we will help match shelving.
When to Involve a Specialist
Some storage plans are easier with a specialist.
A specialist can review your storage areas and help match shelving to each one.
