Drive-In and Drive-Thru racking systems provide high-density storage by eliminating picking aisles, these systems offer low selectivity, making them ideally suited for large quantities of uniform products (same SKU), products that require large, one-time moves and products with long life spans or perishable products that rotate quickly. With this type of system you can store up to 75% more pallets than using standard pallet racks.
Drive-In rack, is best suited for last-in, first-out (LIFO) storage configuration, while Drive-Thru systems are similar to Drive-In racks but can be accessed from either end and can be configured as first-in, first-out (FIFO). Both these storage rack systems offer maximum storage density.
