Pallet Racking
Pallet racking is a warehouse storage system built from vertical steel uprights and horizontal load beams (SJF). SJF lists selective rack for direct access to every pallet plus drive-in rack for high-density storage. MH-USA says Selective pallet rack is the most common warehouse racking system. Interlake Mecalux lists direct access to each pallet.

How pallet racking is built
SJF says Pallet racking is a warehouse storage system built from vertical steel uprights and horizontal load beams — designed to store palletized goods in multiple levels and rows, making full use of vertical space that would otherwise go unused and The most common construction style is teardrop pallet racking, where beams slide into teardrop-shaped holes in the uprights and lock without bolts. Interlake Mecalux says The posts are slotted every 2" to accommodate the beams. Mecalux says The uprights are slotted every 50 mm to accommodate the beams.
Sizes, capacity framing, and published costs
MH-USA lists frame depths 36″, 42″, 48″ with 42″ standard for 48″×40″ pallets; 48″ for oversized loads, plus beam lengths 92", 96", 108", 120", 144". Interlake Mecalux says Rack heights typically range from 4' to 40'. DACO says The most common bay size is 96 inches wide by 44 inches deep. SJF says maximum allowable beam deflection is defined as L/180 with a 96-inch beam has a maximum permissible deflection of approximately 0.53 inches (96 ÷ 180). Hammerhead says New selective pallet racking from quality manufacturers runs $80 to $100 per position for non-seismic applications and $100 to $120 for seismic, and Reynolds says Complete installed selective systems with accessories and labor commonly fall between $150 and $450 per position.

Frequently Asked Questions
What is pallet racking?
SJF says Pallet racking is a warehouse storage system built from vertical steel uprights and horizontal load beams — designed to store palletized goods in multiple levels and rows, making full use of vertical space that would otherwise go unused. Interlake Mecalux says Obtain precise stock control and direct access to each pallet. MH-USA says every pallet position is directly accessible by forklift from the aisle.
How common is selective pallet racking?
MH-USA says Selective pallet rack is the most common warehouse racking system. DACO says It is the most widely used racking system in the industry, largely because it offers 100% selectivity. Interlake Mecalux says Single-deep pallet racks This is the standard, most commonly used configuration in most warehouses.
What cost ranges are published for selective rack?
Hammerhead says New selective pallet racking from quality manufacturers runs $80 to $100 per position for non-seismic applications and $100 to $120 for seismic. Reynolds says Complete installed selective systems with accessories and labor commonly fall between $150 and $450 per position. Conesco says Installation typically runs $20–$250 per pallet position. MH-USA says Cost per position varies by rack type, height and capacity.
