Pallets are transport structure that supports goods and is removed in a stable manner by forklift trucks, pallet trucks, front loaders or other top devices for handling. Containerized transport prompts people to use pallets because the surface of sea containers is smooth and flat, making it easy for pallets to move.
Wooden pallets are usually made up of three or four trusses that support multiple decks and place cargo on them.
In pallet measurements, the first number is the length of the longitudinal beam and the second is the length of the bearing plate. A square or approximately square tray helps the load resist tilt.
North American Pallet Weight
Pallet weight generally depends upon pallet size, and the load bearing capacity of the pallet. On average, an empty wooden pallet will weigh from 30 lbs. to 70 lbs., depending on wood type (i.e. hardwood/softwood mix) and the moisture content of the wood. A standard wooden pallet (48″ x 40″ x 6″) with a static load bearing capacity of 3 tons and a 1 ton dynamic, will weigh approximately 33 lbs. to 48 lbs. Lightweight plastic pallets can weigh as little as 3 to 15 pounds, while heavier models may weight up to 30 pounds.
Maximum weight loads also depend on the pallet size and type. Weight loads for standard North American sized pallets typically are:
- 48″ x40″ sized pallets have weight load of 4,600 lbs
- 36″ x 36″sized pallets have weight load of 4,700 lbs
- 42″ x 42″sized pallets have weight load of 3,700 lbs
- 48″ x 48″sized pallets have weight load of 3,700 lbs
Note that some carriers such as Federal Express have their own weight and dimension restrictions. Fedex’s minimal weight a pallet can carry is 151 lbs. and maximum weight load is 2,200 lbs. DHL Express’ minimum is 66 lbs. and maximum weight load is 2,204 lbs.
Euro Pallet Weight
Euro pallets have standardized weight requirements set by the European Pallet Association (EPAL). Due to strict size and construction requirements, Euro pallets are heavier, with standard weights of approximately 25 kg (55.1 lb). To conform to Euro standards, the pallet must provide a safe working load of 1,500 kg (3307 lb.), and a maximum additional load of 4,000 kg when stacking (8818 lb.)
As a result of the International Plant Protection Convention (IPPC abbreviation), pallets that cross national borders must isolate insect and plant diseases that invade species through carrier materials.
Pallets made of untreated wood do not conform to ISPM 15. In order to meet the requirements, pallets (or other wood packaging materials) must meet the registration criteria and must be processed under approved supervision in any of the following ways:
The treated wood tray must be imprinted on two opposite sides, indicating the HT used for heat treatment or the MB used for methyl bromide treatment.
Although the pallets are available in a variety of sizes and configurations, all pallets fall into two broad categories: Block Pallet and Stringer Pallet.
Block pallets are generally considered to be stronger and more durable than Stringer Pallet.
The cheapest pallets are made of cork and are often thought to be consumable and can be discarded as garbage with other wrapping elements. These pallets are simple longitudinal girder trays that can be lifted from both sides.
The general hardwood block tray, plastic tray, and metal tray can be raised from four sides.
Paper trays, also known as "ecopallets", are commonly used for light loads, but enhanced optimized paper trays have gradually taken possession of the wood tray market.
Steel pallets are strong and can be used for heavy loads, high stacking loads, long-term dry storage, etc., and are commonly used in military munitions, accounting for less than 1% of the market. Materials include carbon steel, stainless steel, and aluminum.
Aluminum pallets are stronger than wood or plastic, lighter than steel, and resistant to weather, decay, plastic creep, and corrosion. They are sometimes used for air transport, long-term outdoor or offshore storage, or military transport.
Plastic pallets are usually made of new HDPE or recycled PET (beverage bottles). They are usually very durable, last 100 or more times, and are resistant to weathering, decay, chemicals, and corrosion. The advantages of plastic pallets relative to wooden pallets include ease of disinfection, odor resistance, flame retardant, longer service life, durability, and better product protection, non-splitting, and lighter weight, thus saving transportation and labor costs, making them safer, greener, and easily disinfected for international transport.
