There are basically two types of pallets depending on what you wish to use them for. But mostly the term is used in reference to a kind of platform that allows for easy moving and storage of stacks of goods. These basically come in two forms. One is the wooden pallets which have for a long time been the industry norm. Their use is widespread and varied. Basically this is made by joining timber together.
The joining of this timber is in an order that will allow goods of a given weight to be stacked on top of it to allow for easy transportation mostly using a forklift. This also allows for easy storage of goods as the pallets allow goods to be stacked at a given clearance of the floor. Care should be taken that the wood used and how it is joined allows for the pallet to carry the weight of the goods.
