Cold Storage Pallets: Types, Sizes & How to Choose

Most pallet problems in cold storage don’t show up on day one — they show up six months later when a pallet cracks under load, or when mold starts appearing on goods that were supposed to be safely stored. By then, the damage is already done.

The right cold storage pallet prevents all of that. In this guide, we’ll walk you through materials, sizing, cold storage pallet racking compatibility, and how to match the right pallet to your actual operation — so you’re not finding out the hard way.

What is a Cold Storage Pallet？

A cold storage pallet is specially designed for low-temperature environments and is widely used for storing and transporting goods like fruits, vegetables, meat, seafood, pharmaceuticals, and chemicals. These goods are highly sensitive to temperature fluctuations, so cold storage pallets must remain stable in environments between -20°C and -30°C, without becoming brittle or deformed. 

This is why cold storage pallets are crucial for industries like food, pharmaceuticals, and seafood—they ensure your goods are well-protected and prevent damage during storage.

What Features Should a Cold Storage Pallet Have?

Low temperature resistance and structural stability are important — but they’re not the whole picture. Here are the key features your cold storage pallet should have:

1. Moisture and Mold Resistance: Cold storage environments tend to have high humidity. If moisture gets into your pallet material and reaches your goods, mold becomes a real problem. Your pallet needs to keep that moisture out.

2. Chemical Resistance: Pallets should be able to handle exposure to acids, alkalis, and salts without breaking down — especially if you’re storing or transporting chemicals or certain food products.

3. Easy to Clean: For operations with strict hygiene requirements, look for pallets with smooth, seamless surfaces. They’re much easier to wash down and are more likely to meet FDA or EU food contact material standards.

One note: you’ll find many vented-surface pallets marketed as “hygienic.” They’re not wrong — but vented pallets are better suited for environments that need airflow to prevent mold, like short-term storage of fruits and vegetables. They’re not the first choice for most cold storage applications.

4. Load Capacity: Cold storage pallets are typically used in racking systems and for stacked storage, so they need to handle the weight reliably without flexing or failing over time.

5. Durability and Service Life: If you’ve been running your cold storage operation for over ten years, the last thing you want is pallets slowing you down. A good cold storage pallet should last at least 5-8 years at minimum — because replacing pallets also means reorganizing your warehouse around them. Material quality and build structure are still the two biggest factors that determine how long a pallet actually lasts.

Here’s a quick comparison of typical service life by pallet type:

Tipo de palet	Service Life	Durabilidad	Notas
Virgin HDPE	10–15 years	Alta	Excellent cold resistance, chemical resistance, and moisture resistance. Holds up well under frequent, long-term use.
PP	8–12 years	Media	Good cold resistance, but slightly less durable than HDPE under high loads over time.
Steel	10+ years	Alta	Very strong load capacity. Needs anti-corrosion treatment to stay reliable in cold, humid conditions.
Madera	5–8 years	Baja	Absorbs moisture easily. Without proper treatment, mold and damage are common — especially in high-humidity cold storage.
Aluminum	15+ years	Alta	Outstanding cold and corrosion resistance. Higher cost and lower load capacity than steel, but ideal for specialist cold chain needs.

6. Weight: Lighter pallets are easier to move and stack, which matters more than people often expect in a busy cold storage operation. Here’s how common materials compare:

• PP pallets are among the lightest options available — a good fit for fruits, vegetables, seafood, and other lighter goods.
• HDPE pallets are slightly heavier than PP due to higher material density, but still manageable for most operations.
• Wooden pallets are generally heavier than plastic — the added weight comes with better support for heavier loads, but at the cost of handling ease.
• Aluminum pallets are the lightest metal option, though still heavier than plastic pallets.
• Steel pallets offer the highest load capacity of any material — but they’re also the heaviest. If you need steel-level strength, weight is the trade-off you’ll make.

Which Pallets Are Suitable for Cold Storage Use?

Not every pallet is built for the cold storage. Temperature swings, moisture, and constant freezing cycles can crack, warp, or weaken the wrong material fast. Here’s a quick breakdown of the main types for your operation:

1. HDPE Plastic Pallets 

Among all plastic pallet materials, the HDPE pallet has the widest temperature range — stable from -40°C to 70°C without any additives. In practical terms, that means your pallets won’t go brittle or warp in deep freeze conditions the way wood pallets often do. They hold up well under heavy loads on cold storage racking, and with proper use, you can reasonably expect 10+ years of service life.

HDPE is also naturally moisture-resistant, which helps prevent mold and bacteria buildup over time. If you’re in food storage or pharmaceutical distribution — where hygiene standards are non-negotiable — that’s a real advantage that’s easy to overlook until you’re dealing with a contamination issue.

2. PP Plastic Pallets (Polypropylene) 

PP pallets are a reliable option for cold storage environments that stay above -20°C. Because PP has a lower material density than HDPE, a PP pallet made from the same mold and process will come out lighter — and that difference adds up when your team is moving pallets frequently throughout the day. 

PP doesn’t handle extreme cold as well as HDPE, but it still outperforms wood pallets in most real-world cold chain settings. If you’re in food refrigeration, pharmaceutical storage, or similar industries where loads aren’t extremely heavy and temperatures don’t drop too low, PP is a practical and cost-effective choice worth considering.

3. Steel Pallets 

Steel pallets are the right choice when you need to store heavy goods like machinery or industrial equipment. They stay solid between -30°C and 70°C, and they don’t bend or break down under heavy loads over time.

Just keep in mind that bare steel can rust in cold, humid conditions. Getting pallets with a galvanized or powder-coated finish takes care of that — it’s worth checking before you buy.

4. Aluminum Pallets 

Aluminum pallets work well in temperatures from -40°C to 100°C, and because aluminum doesn’t rust, you won’t need much maintenance over the long run. They’re also lighter than steel, which makes a real difference when your team is moving pallets around regularly.

The one limitation is that aluminum can’t handle very heavy loads as well as steel can. But if you’re in biopharma, deep-frozen food, or similar industries where weight isn’t the main concern, aluminum is a strong option.

5. Treated Wooden Pallets 

Wooden pallets are the most affordable option here. If your cold storage stays between -10°C and 30°C and your loads aren’t too heavy, treated wood gets the job done — and you can usually get them made to fit your specific storage layout.

The downside is that wood absorbs moisture over time, which can lead to mold in cold, damp conditions. So wood pallets work best in places where hygiene requirements aren’t too strict, or when you only need them for short-term use.

The right pallet depends on your temperature range, load weight, and hygiene requirements. If you’re not sure which material fits your setup, we’re happy to help you work through it.

What Are The Sizes Of Cold Storage Pallets?

There’s no single universal standard for cold storage pallet sizes. The table below is based on actual requirements from our customers across different industries — think of it as a practical starting point, not a fixed rule.

Industria	Common Pallet Size	Notas
Meat Processing	1200 × 1000mm	Handles high load capacity and frequent movement. Stays stable in cold storage conditions.
Fruits & Vegetables	1200 × 1000mm, 1200 × 800mm	The larger size works better for bulk storage. Both sizes suit cold storage for perishable goods.
Seafood	1200 × 1000mm, 1200 × 800mm	Hygiene and moisture resistance are the priority here. Both sizes are widely used in seafood cold chain.
Dairy	1200 × 1000mm	Good fit for bulk dairy storage where moisture resistance and low-temperature stability matter.
Beverages & Beer	1200 × 1000mm	Works well for both bottled and canned products. Needs solid cold resistance and moisture protection.
Farmacéutica	1200 × 1000mm, 1200 × 800mm	High hygiene standards apply. Both sizes are commonly used and meet typical pharmaceutical storage requirements.
Logística de Cadena de Frío	1200 × 1000mm, 1200 × 800mm	Covers most cold chain scenarios. Size can be adjusted based on cargo type and how goods are stored or transported.
Chemical Storage	1200 × 1000mm	Needs strong load capacity and chemical resistance. This size handles heavy chemical products well in cold environments.

The right size for you depends on your racking system, cargo weight, and how your warehouse is laid out. If you’re not sure where to start, feel free to reach out — we’re happy to help you match the right pallet size to your actual setup.

How to Choose the Right Cold Storage Pallet?

Cold storage pallets are used in three main situations: on the floor, on racking systems, and in regular handling operations. Each situation has different requirements, so let’s work through them one by one.

How to Choose a Pallet for Frequent Handling

As a general rule, if your pallets are being moved 3–5 times or more per day, that counts as frequent handling — and your pallet choice needs to reflect that.

Two things matter most here:

• Weight: For manual handling, the pallet itself should weigh under 10kg. Anything heavier puts unnecessary strain on your team over the course of a full shift.
• Impact resistance: For forklift operations, bumps and scrapes are unavoidable. You need a pallet that can take repeated impact without cracking or breaking down. Wooden pallets don’t hold up well here.

Our recommendation: HDPE pallets. They’re light enough for manual handling, tough enough for forklift use, and resistant to the kind of surface damage that comes from daily cold storage operations. PP pallets are a reasonable second choice for lighter loads, though they’re not quite as durable under heavy, frequent use.

How to Choose a Pallet for Floor Storage

Cold storage floors are often used for temporary staging — holding goods while they wait to be moved to racking or shipped out. For floor use, two things should guide your decision:

• Moisture resistance first. Cold storage floors tend to have higher humidity than the rest of the facility. Your pallet must not absorb water, or you risk mold growth and structural damage to both the pallet and your goods.
• Load capacity second. Make sure the pallet can handle the full weight of whatever you’re stacking on it. A pallet that flexes or fails under load creates a safety risk and potential product loss.

If your cold storage stays around 10°C and handling requirements are low, a moisture-treated wooden pallet can work as a cost-effective option. But for food or pharmaceutical storage — or anywhere the floor stays cold and damp for long periods — wood isn’t a reliable long-term solution.

For most cold storage floor applications, HDPE or PP nine-leg pallets are the better choice. The nine-leg structure distributes weight evenly across the floor, avoiding concentrated pressure on any single point. A good nine-leg plastic pallet typically offers a static load capacity of around 4 tons, which covers most floor storage needs comfortably.

How to Choose a Pallet for Cold Storage Racking

Cold storage racking systems make the most of vertical space — but they also put sustained, long-term pressure on your pallets in a way that floor storage doesn’t. And if your pallet size doesn’t match your racking system, you’re either wasting space or creating a safety risk. Both problems are easy to avoid if you know what to look for.

What Makes Racking Different from Floor Storage

A pallet sitting on a rack beam with a full load may stay in that position for days or weeks at a time. That kind of sustained pressure causes creep — a gradual, permanent deformation that happens even when the pallet isn’t technically overloaded. To slow this down and get the most out of your pallets on the rack:

• Choose high-density materials. Higher density resists long-term deformation better.
• Look for steel-reinforced pallets. An internal steel tube significantly slows creep and extends the pallet’s usable life. Both HDPE and PP pallets can be reinforced this way, typically bringing static load capacity up to around 6 tons.
• Don’t exceed the rated load. Running pallets over their stated limit is the fastest way to shorten their lifespan.

For most cold storage racking applications, HDPE is our first recommendation — strong load capacity, good dimensional stability, and reliable performance at low temperatures.

As a general guideline, we recommend:

• Static load: at least 2 tons
• Dynamic load: over 1 ton
• Rack load: at least 1 ton

One practical tip: in low-temperature environments, buy to a higher load rating than your actual requirement. Cold affects material performance. If you need a 0.5-ton rack load at -30°C, specify a pallet rated for 0.75–1 ton to keep a safe buffer.

3 Racking Parameters You Need to Know Before Buying

Pallet size has to match your racking system — not the other way around. Before you place an order, measure these three things:

Upright Depth This is how deep your rack is from front to back. Your pallet length needs to match this. Too short and the pallet sits unstably; too long and it overhangs the beam. Most racks run 1000–1200mm deep, which corresponds to standard pallet lengths of 1000mm or 1200mm.

Beam Length This is the distance between the two upright columns on each rack bay. It determines how many pallets fit side by side in one row. For example, a 2700mm beam length typically fits two 1200mm-wide pallets with a small gap between them for clearance.

Rack Height Total rack height tells you how many levels you can stack. But the usable height per level isn’t the full tier spacing — it’s the tier spacing minus the beam thickness. Your pallet plus cargo must fit within that clearance, or your forklift won’t be able to operate safely.

Which Pallet Works Best for Your Rack Type?

Selective Racking The most common rack type in cold storage. Each pallet is individually accessible, and sizing is fairly standard. A 1200×1000mm four-way entry HDPE pallet works well here and covers most food and pharmaceutical cold storage setups.

Drive-In Racking Forklifts drive directly into the rack to place and retrieve pallets — good for high-volume, single-SKU storage. Pallet width must match the rail spacing precisely. Even a small mismatch can cause pallets to jam or tip. Before ordering, send your rack rail dimensions to your pallet supplier and confirm the fit before committing.

Narrow Aisle Racking Higher storage density, but tighter operating space. Because the aisles are narrow, even slight pallet deformation can cause problems during forklift operations. Choose dimensionally stable HDPE pallets and make sure the pallet width is at least 100mm narrower than the aisle clearance.

Pallet Flow Racking Pallets move on built-in rollers from the loading end to the picking end by gravity — a natural fit for FIFO inventory management. The pallet base must be flat and smooth, or the rollers won’t distribute load evenly and the pallet will jam or drift. Use flat-deck HDPE pallets here. Nine-leg or complex-base designs don’t work well on flow racking.

High Rise Racking Often paired with automated storage and retrieval systems (AS/RS), with rack heights reaching 10 meters or more. Automated systems run on fixed parameters, so dimensional accuracy matters a lot — a pallet that’s slightly out of spec can trigger equipment errors. Choose HDPE or steel pallets with tight dimensional tolerances, and confirm the exact pallet spec with your automation system supplier before ordering.

Rotary Racking The rack itself rotates to bring pallets to the operator. Pallet size must match the carrier dimensions of the rotation mechanism exactly. Don’t source pallets independently and try to make them fit after the fact — confirm the required spec directly with your rack supplier before purchasing.

Block Stacking No racking involved — pallets are stacked directly on the floor. The bottom pallet carries the full weight of everything above it, so load capacity and deformation resistance matter more here than in any rack application. Choose high-capacity HDPE pallets and set a firm limit on stacking height to avoid long-term compression damage to the bottom layer.

How Do You Maintain Your Cold Storage Pallets?

Pallets in cold storage face more wear than pallets used at room temperature — mold, frost buildup, and cracking are all more common in low-temperature, high-humidity environments. Here are some straightforward maintenance steps to keep your pallets in good shape:

Remove ice and frost regularly. When frost or ice builds up on a pallet, move it to a slightly warmer area to handle it — don’t try to chip ice off inside the freezer. For plastic pallets, use a dedicated scraper or warm water to clear the surface. Forcing frozen buildup off with the wrong tool can crack the pallet.

Clean mold promptly. Use a disinfectant or sanitizing solution to deal with any mold growth. Plastic pallets can handle high-pressure washing, which is the most effective way to remove mold and odor. Avoid harsh chemicals that leave residue — they can contaminate your goods and break down the pallet material over time.

Inspect pallets every 1–2 months. Plastic pallets are moisture-resistant, but extended exposure to cold, damp conditions does affect the material over time. Check for cracks, warping, or any visible deformation on a regular basis. If you spot damage, replace the pallet rather than continuing to use it — a compromised pallet under load is a safety risk.

Use proper stacking practice on racking. If your pallets are used on a racking system, make sure they’re always positioned correctly on the beams. Uneven support — where the pallet overhangs or sits off-center — causes stress to concentrate in one area, which speeds up deformation and shortens the pallet’s life.

FAQ About Cold Storage Pallets

Can I use a regular plastic pallet instead of a cold storage pallet?

No. Cold storage environments typically run between -30°C and 10°C, and regular plastic pallets often contain a high percentage of recycled material that becomes brittle and cracks below -10°C. Cold storage pallets are made from virgin HDPE or PP, which stay stable down to -40°C. It’s not a small difference — using the wrong pallet in a deep freeze environment is a real safety and product loss risk.

Are plastic pallets better than wooden pallets for cold storage?

Yes, plastic wins here. Plastic cold storage pallets handle low temperatures, moisture, mold, and chemical exposure much better than wood. Wooden pallets absorb moisture over time, which leads to mold growth and structural weakening — neither of which you want in a cold storage environment, especially for food or pharmaceutical goods.

How long does a cold storage pallet last?

A virgin HDPE or PP cold storage pallet typically lasts 10–15 years. With regular cleaning and basic maintenance, you can reasonably extend that by another 2–3 years.

Which certifications should I look for in a cold storage pallet for food use?

For food-grade cold storage, look for pallets with FDA, EU food contact, or ISO certification. These confirm the material is non-toxic, odor-free, and safe for use around food products. Note that CE and REACH certifications serve different purposes — they don’t qualify a pallet for food contact use, so don’t let those labels substitute for the right ones.
