Types of Pallets

Stringer Pallets

Stringer pallets are one of the most common types of pallets used in shipping and logistics. They are called stringer pallets because they have stringer boards that run perpendicular to the deckboards, providing strength and stability. Stringer pallets are often made from softwood like pine or fir and can be easily repaired or replaced when damaged.

Block Pallets

Block pallets are another popular type of pallet design. Unlike stringer pallets, block pallets have blocks that extend vertically between the top and bottom decks, providing additional support and load-bearing capacity. Block pallets are typically made from hardwood like oak or beech, which gives them extra strength and durability. These pallets are often used for heavy-duty applications or when extra stability is required.

Euro Pallets

Euro pallets, also known as EUR pallets or EPAL pallets, are widely used in Europe and other parts of the world. They are standardized to have dimensions of 800mm x 1200mm and are designed specifically for compatibility with European handling equipment. Euro pallets are typically made from softwood and have 3 bottom deckboards with 9 blocks supporting the top deckboards.

Plastic Pallets

Plastic pallets have gained popularity in recent years due to their durability, hygiene, and ease of cleaning. They are made from high-density polyethylene (HDPE) or other plastic materials, which make them resistant to moisture, chemicals, and insects. Plastic pallets are generally lightweight and can be easily recycled, making them a sustainable option for businesses looking to reduce their environmental impact. They are commonly used in industries such as pharmaceuticals, food, and electronics.

Dimensions of Pallets

Standard Pallet Sizes

Standard pallet sizes vary across different regions and industries. In North America, the most common standard pallet size is 48 inches x 40 inches. This size is compatible with most handling equipment and is widely used in the transportation industry. In Europe, as mentioned earlier, the standard Euro pallet size is 800mm x 1200mm. Other standard pallet sizes include 42 inches x 42 inches and 36 inches x 36 inches. These standard sizes are typically used for specific applications or when certain loading or handling requirements need to be met.

Custom Pallet Sizes

In addition to standard sizes, businesses may require custom pallet sizes to meet their unique needs. Custom-sized pallets can be manufactured to accommodate unconventional load dimensions or fit within confined spaces. Although custom-sized pallets may incur higher production costs compared to standard sizes, they can optimize storage and transportation efficiency, minimizing wasted space and reducing overall expenses.

Components of a Pallet

Deckboards

Deckboards are the horizontal boards on top of the pallet that support the load. They provide a sturdy surface for the goods to rest on and distribute the weight evenly across the pallet. Deckboards are typically made from solid wood or plywood. Their thickness and spacing can vary depending on the intended use and load capacity requirements of the pallet.

Stringers/Blocks

Stringers or blocks are the vertical components of a pallet that support the deckboards. In stringer pallets, there are usually two or three stringers that run between the top and bottom decks, while block pallets have blocks that extend vertically. Stringers and blocks provide structural stability to the pallet and determine its load capacity.

Top Boards/Bottom Boards

Top and bottom boards are additional components that can be found on some pallet designs. Top boards are placed on top of the deckboards to provide extra protection and stability to the load, especially when stacking multiple pallets. Bottom boards, on the other hand, are placed underneath the deckboards to reinforce the lower portion of the pallet and protect it from damage during handling or storage.

Nails/Screws

Nails or screws are used to hold the components of a pallet together. They play a crucial role in ensuring the strength and stability of the pallet, especially when it is subjected to heavy loads or rough handling conditions. The type and length of nails or screws used can vary depending on the pallet design and the type of wood being used.

Wood Species Used in Pallets

Softwood

Softwood is the most commonly used wood species in pallet manufacturing. It includes varieties such as pine, fir, and spruce. Softwood is preferred for pallet construction due to its affordability and abundance. It possesses good strength-to-weight ratio and can withstand heavy loads, making it suitable for most shipping and storage applications. Additionally, softwood is relatively easy to work with, making repairs or modifications to pallets more convenient.

Hardwood

Hardwood species like oak, beech, and maple are also used in pallet construction, particularly for heavy-duty applications. Hardwood pallets offer greater strength, durability, and resistance to wear and tear compared to softwood pallets. They can withstand heavier loads and are more resistant to cracking or breaking under pressure. Although hardwood pallets may be more expensive initially, they often have a longer lifespan and can be a cost-effective choice in the long run.

Treated Wood

Treated wood, regardless of whether it is softwood or hardwood, undergoes a preservative treatment to enhance its resistance to decay, insect damage, and moisture absorption. This treatment process involves the application of chemicals or heat treatment to prolong the lifespan of the wood and protect it from environmental factors. Treated wood pallets are commonly used in outdoor or high-moisture environments where there is a risk of fungal decay or insect infestation.

Wood Consumption in Pallet Manufacturing

Board Feet

The measurement typically used to quantify the amount of wood used in pallet manufacturing is board feet. One board foot is equivalent to the volume of wood that measures 1 foot by 1 foot by 1 inch. Pallet manufacturers estimate the amount of wood needed for a pallet by calculating the total board footage of all the components like deckboards, stringers/blocks, top boards/bottom boards, and reinforcements.

Cubic Feet

In addition to measuring wood consumption in board feet, the volume of wood used in pallet manufacturing can also be measured in cubic feet. Cubic feet is a measure of the total volume of wood used, regardless of the specific dimensions or thickness of the individual components. This measurement is helpful in understanding the overall size and weight of pallet shipments when planning transportation or storage.

Factors Affecting Wood Consumption

Pallet Design

The design of a pallet can have a significant impact on the overall wood consumption. Different designs may require varying numbers of deckboards, stringers/blocks, or additional components. Design choices such as the spacing between deckboards or the thickness of wood used for each component can also affect the total volume of wood required.

Pallet Weight Capacity

The weight capacity of a pallet is another factor that affects wood consumption. Pallets designed for heavier loads may require more substantial components, such as thicker deckboards or extra stringers/blocks, to provide adequate strength and support. This increased material usage can result in higher wood consumption compared to pallets with lower weight capacities.

Material Handling Equipment

The type of material handling equipment used with the pallets can influence wood consumption. Some handling equipment, such as forklifts or automated systems, may require pallets to have specific dimensions or additional reinforcements for secure handling. These equipment requirements may impact the design or size of the pallet, potentially affecting the amount of wood used.

Environmental Considerations

Pallet Recyclability

One of the significant environmental benefits of wooden pallets is their recyclability. Wood is a renewable resource, and when a pallet reaches the end of its life, it can be recycled into wood chips, mulch, or even new pallets.
