There are three basic components of a pallet rack. They include the
1. Upright Columns
2. Horizontal, Diagonal and or Cross Braces
3. Horizontal Shelf Beams
The columns and brace sets combine to form the upright frame. The horizontal shelf beams connect to the upright frames to form a storage level onto which palletized containers or unit loads are placed.
Pallets and or unit loads can be stored side by side in the down aisle direction on each storage level.
Accessories for standard pallet racks include row spacers or back to back ties, these are used when the rack bays are positioned back to back.
Front to rear members come in a variety of types, these include drop on members, flanged and unflanged, drop in drum supporting members and drop on skid supporting members.
