What is a Pallet?
Pallet Design and Storage

A pallet, otherwise commonly known as a "skid," is often used as a base or foundation to assemble, handle and stack individual or multiple boxes or goods on. A shipping pallet's uniform design is structured to support and distribute the weight and size of the load. Once goods are stacked on a pallet, they are sometimes stabilized using strapping, stretch wrap or other wrapping material so that the load doesn’t move or shift and is protected from fall offs.

Most importantly, pallets are designed to allow material handling equipment such as forklifts, front loaders or pallet jacks to lift and move these supported items from place to place. This makes transporting multiple or large items a much less complicated issue.

In the logistics or material handling industries, reliable pallets are essential. They are commonly used in material handling systems such as pallet racking or carton flow rack for storage or organization, where the pallets with stored materials can be easily accessed and moved using fork trucks. Pallets are also commonly used in conveyor operations as well, to transport loaded pallets easily and in an organized fashion from on place to another.

The most common type of pallet is made from wood, but there are other types of pallets that are better adapted for certain industries, such as metal pallets, aluminum pallets and plastic pallets. Other pallets are also made of paper or cardboard. Standards for each vary but each style has its own distinct advantage depending upon the environment that they are used in.


Wood Pallets

Wooden Pallets

Wooden pallets are the most widespread and common type of pallet used and offer a good combination of cost and durability. "Stringers" or "blocks" are typically used to support the deck boards. Stringer pallets use 2-x-4 inch boards for support and block pallets use 4-x-4 inch blocks.

The majority of warehouses use wooden pallets in their daily operations. For the material handling industry, wood pallets are the standard. One distinct advantage of using wood pallets is the low cost and recyclability.

Wooden pallets are oftentimes built using common measurements for widespread use. The standard size of a wood pallet in the United States is 48" x 40". Most are made from waste lumber, which is still strong, reusable and cost-effective, but doesn't require cutting down trees to produce. The wood used to create these pallets is treated for protection against moisture and insects for safety and durability.


Plastic Pallets

Plastic Pallets

Plastic pallets, made of recycled and recyclable molded plastic, are also a common option for storing goods. A lighter weight option, plastic pallets often are preferred over wooden pallets due to their durability. They tend to last longer than wooden pallets, are easier to clean, are FDA and USDA approved and have no fasteners or splinters to deal with. They are also typically more expensive to purchase.

There are many different styles of plastic pallets with options ranging from weight capacity to drainage capability to complex-ability. Plastic pallets can be nestable, stackable and can be used in rack systems for easy four-way access.



Aluminum Pallets

Metal Pallets or Aluminum Pallets

Metal or aluminum pallets are the pallets the food, rubber, pharmaceutical and chemical industries commonly use. They are made of heavy duty welded metal or aluminum construction. Over time, aluminum pallets maintain their structural integrity and are free from rust, warping and rot, unlike wood pallets. Aluminum pallets are also durable, lightweight, fire-proof and recyclable.

These pallets are easy to clean and can withstand high-powered steam, pressure washers or scrubbing. They can be sterilized for markets with rigid sanitation requirements. Aluminum pallets tend to have a longer lifespan than typical wood pallets.
