Wooden pallets are an essential element of modern logistics infrastructure, allowing to facilitate and standardise the processes of moving, storing and transporting a wide variety of goods. Their use has become so ubiquitous that it is difficult to imagine the efficient operation of large distribution centres, manufacturing plants and retail chains without the use of this simple but very functional element. Convenience of warehouse operations, economic efficiency and reliability of the logistics chain directly depend on the types and types of pallets.
Choosing the right pallet is not just a matter of aesthetics or formal standards. It is important to understand the differences between the different types, the most common types of wooden pallets in different countries, and the differences in size, construction and load capacity.
In addition, when purchasing both new and used variants, their grade should be taken into account. The grades of pallets (e.g. grade 1, grade 2 or grade 3) determine their condition, strength, service life and appearance. Knowing how pallets look and are classified according to these parameters, you can optimise costs, improve turnover and increase safety when handling goods.
In this article we will look in detail at the main types of wooden pallets, consider their belonging to different standards, typical sizes, features of sorting, as well as pay attention to the criteria for classification by design and load capacity. Understanding this information will help you make an informed choice based on specific logistical challenges and industry requirements.
Types of pallets
There are several types and kinds of pallets that are most widely used in international logistics. These categories have been formed over the years, based on the standards of specific regions and industries. Let’s consider the main ones:
Europallets
- Dimensions and standards : Euro pallets comply with the 1200×800 mm standard and are considered one of the most unified formats in the world.
- Advantages :
- Universal application in Europe and many other countries
- Ease of integration into automated warehouse systems
- Optimization of logistics thanks to strictly regulated dimensions
- Areas of application : Suitable for most product groups, used both in manufacturing plants and in retail chains.
- Important point : Euro pallets are often purchased as new or used options, which allows you to choose the optimal balance between price and quality.
Finnish pallet/American pallet
- The main difference : The overall dimensions of Finnish pallets are most often 1200×1000 mm.
- Difference with the Euro : The Finnish format is wider, which in some cases ensures more rational placement of certain types of cargo.
- Features of application :
- Widely distributed in Scandinavia and Russia
- Suitable for warehouses with non-standard shelving equipment
- Used for goods with special logistics requirements
Non-standard pallets
Manufactured according to individual customer orders in accordance with technical specifications.
It is important to note that the choice of pallet standard depends on the company’s logistics strategy, geography of deliveries, available warehouse equipment and the size of the cargo compartments of vehicles. Understanding what the main types are, it is easier to adapt the work to the specifics of your business.
Types of used pallets
The key criterion for choosing wooden pallets is often their condition, clearly reflected in the grade. Different grades allow you to determine the degree of wear, the number of acceptable defects and the scope of application of the pallets. In general, the following types of sorting can be distinguished:
- 1st grade :
- Almost new pallets, no chips, cracks, no darkening, no signs of use (no dirt, paint, oil stains)
- Maximum service life and better aesthetics (important if pallets are visible to customers or used in open areas)
- Ideal for sensitive cargo requiring careful handling
- 2nd grade :
- Minor defects are allowed: minor chips, darkening of wood, traces of use
- Strength characteristics remain at a high level
- Ideal choice for indoor operations where appearance is not as critical but reliability is important
- 3rd grade :
- Visible signs of wear, possible uneven color range of the wood, small cracks or darkening in places
- Suitable for secondary tasks, temporary storage or intra-warehouse movement of secondary loads
- Affordable price.
Types of new pallets
1st grade:
- Manufactured in full compliance with GOST 33757–2016.
- Precise parameters and shape: maximum permissible deviation ±2 mm.
- Planed edged board is used.
- One-sided peeled blunt wane is allowed provided that in total it does not exceed 50% of the thickness (height) of the board and no more than 25% of its width.
- In the total mass of material in the cassette, the proportion of boards with wane is a maximum of 30%.
- Elements with blue stain, bark, sharp wane, rot or mold are prohibited for use.
2nd grade:
- Complies with GOST 33757–2016.
- Focused on high geometric accuracy: permissible dimensional deviations are ±2 mm.
- Application of edged board.
- Double-sided blunt wane is permitted provided that it does not exceed 50% of the thickness and in total does not occupy more than 20% of the board width.
- A maximum of 30% of the material in a package (cassette) may contain wane.
- Prohibited characteristics include bark, sharp wane, rot, mold and blue stain.
3rd grade:
- Permissible dimensional variations: in height – up to ±5 mm, in board width – ±10 mm.
- Unedged boards are used.
- Double-sided blunt wane may cover no more than 40% of the board width.
- One-sided debarked sharp wane should not exceed 20% of the width.
- A slight manifestation of blueness is allowed (both on the wane and on the clean surface), but not more than 15% of the area of one of the sides.
- Bark, sharp wane and blue stain can be neglected on a small scale, but rot and mold are unacceptable.
4th grade:
- The board undergoes a full cycle of additional processing: sanding, planing, and trimming.
- Excess humidity, deviations in thickness, width and length beyond the specified standards are permissible.
- Geometry may be distorted.
- Double-sided blunt wane is permitted within a total of 40% of the width.
- One-sided sharp wane – no more than 40% of the width.
- Minor traces of blue stain present on both the wane and clean parts of the board (up to 15% of the surface of one side) are acceptable.
- Mold and blue stain are allowed, but rot is not acceptable.
A comparative analysis of varieties may look like this:
- 1st grade – for expensive, fragile and important goods, where impeccable aesthetics are important, for food and pharmaceutical production;
- 2nd grade – for everyday logistics in warehouse operational areas;
- 3rd grade – for economical solutions, when the appearance of the pallets and their ideal condition are not important.
Knowing the differences between grades allows you to flexibly plan your budget, using pallets where they are really needed and saving by purchasing cheaper options for secondary tasks.
Classification of pallets by design
The design features of wooden pallets directly affect their functionality, ease of use and compatibility with certain equipment. Let’s consider the main types of designs:
- By number of forklift passes :
- Double-entry : have openings for forklift forks on two opposite sides only.
- Four-way : The forks can enter from four sides, making it easier to maneuver when stacking and loading.
- By flooring location :
- Single deck : decking boards are located only on the top.
- Double-deck : there are decking boards on both the top and bottom.
- Difference : The double-layered version provides additional rigidity and even load distribution, but can be heavier and more expensive to manufacture.
- By the presence of reinforcing elements :
- Some types of pallets are equipped with a central beam or metal inserts.
- This increases their strength, resistance to bending loads and allows for an increase in load capacity.
- By wood type and processing :
- Pallets can be made from coniferous or deciduous wood.
- Heat treatment is possible to increase resistance to moisture and pests (e.g. HT treatment).
- Special impregnations are often used to protect against fungi or mold.
Additional factors influencing the design :
- The presence of cuts for slings, hooks or other fasteners.
The presence of entry and corner chamfers. - Planing quality.
- Type of finishing treatment to prevent delamination of boards
Standard sizes
Standard pallet sizes play a key role in planning warehouse operations, selecting rack systems and calculating logistics routes. Despite the fact that the already mentioned standards – Euro (1200×800 mm), Finnish pallet (1200×1000 mm) – are the most well-known, there are other formats on the market.
Main types and their popularity :
- Europallets (Euro) :
- Size: 1200×800 mm
- Application: in almost all areas where unification and standardization are important
- Finnish pallet :
- Size: 1200×1000 mm
- Application: ideal for warehouses and production facilities where a large base area for placing cargo is important
Other size options :
- 1100x1100mm, widely used in Asia
- 800×600 mm – more compact pallets used for some types of retail
- Special formats made to order for non-standard equipment
When choosing standard sizes, it is important to consider:
- Compatibility with existing racking systems (shelf, front, deep racks)
- Dimensions of doorways, ramps and cargo compartments of transport
- Possibility to efficiently use the internal space of the warehouse: the right choice of size helps to reduce “voids” and increase the overall efficiency of the logistics system
The more accurately the pallet sizes are selected for specific conditions, the easier it is to organize cargo flows and optimize the use of warehouse space. Understanding the options and recognizing the differences between standards, you will be able to make more informed decisions when purchasing and developing logistics infrastructure.
Classification by load capacity
An important criterion when choosing pallets is their load-bearing capacity – the ability to withstand a certain weight of cargo without deformation and loss of strength properties. Different types of wooden pallets are designed for different types of load, which determines their scope of application.
To make an accurate choice, you should consider:
- Maximum load weight : Some pallets can withstand up to 1000 kg, others – 1500, 2000 kg and more. Correct assessment of this parameter minimizes the risk of breakage.
- Load distribution : It is important that the load is evenly distributed across the entire surface of the pallet. If the load is concentrated in one point, even strong pallets can fail.
- Material and thickness of boards : The better the quality of the wood (for example, carefully selected coniferous wood, without knots and cracks) and the thicker the boards, the higher the strength of the structure.
- Reinforcements available : A central beam, metal corners or additional support blocks increase the load capacity.
- Grade : What do the pallets look like and what condition are they in? If we consider grade 1, the probability of withstanding the maximum load is higher. Pallets of grade 2 or grade 3 may have hidden defects and a reduced safety margin.
- Degree of wear (used pallets) : Used options, even if of good quality, will have less predictable strength characteristics. This is especially true when it comes to critical cargo. It is important to understand the difference between new and used material to avoid overloading.
The final choice of load capacity should be based on a thorough analysis of the type of cargo, its storage and handling conditions, the frequency of pallet use, as well as an understanding of the design features, grades and size standards. This comprehensive approach will ensure the reliability, safety and efficiency of the entire logistics chain, while reducing costs and risks of damage to goods.
