Aluminum dock plates are rectangles of steel or aluminum with some type of locking leg with either hand hole or handles to move them. They are used for handtrucks and pallet jack traffic to be manually moved. Dock Boards are like plates but with the addition of structural components above the plate (curbs) & sometimes on the underside as is the case with rail boards. There are different types of locking devices from fixed legs to drop pins or locking rings. Boards are used for forklifts and other vehicle traffic. Yard ramps perform one of two functions, they allow traffic from the ground up into a truck bed or from the dock level down to the ground.
