Pallet Flow Rack Suppliers in Washington — 3 Companies

Pallet flow rack uses gravity roller conveyors set on a slight decline inside a rack structure. Load from the back, pick from the front — pallets roll forward automatically as you pull from the lane. It gives you the density of drive-in with the FIFO rotation that perishable goods and lot-controlled inventory demand. Washington state's warehouse market is driven by the Ports of Seattle and Tacoma (combined, the 4th largest container port system in the US), Amazon's massive presence in the Puget Sound region, and the state's role as a Pacific Rim trade gateway. The I-5 corridor from Seattle to Tacoma is the primary warehouse zone.

When to Choose Pallet Flow Rack

  • ✓FIFO rotation is required (food, beverage, pharma, dated products)
  • ✓You need high density without sacrificing inventory rotation
  • ✓Throughput is high and you can't afford the forklift travel time of selective rack
  • ✓Staging lanes for shipping dock operations
  • ✓Manufacturing line-side buffer storage

Key Specs to Ask About

  • •Lane depth (pallets deep — typically 3-20+)
  • •Pallet weight range (affects roller and brake sizing)
  • •Lane pitch (degree of decline — usually 3-5%)
  • •Roller type (steel, poly, full-width vs. split-roller)
  • •Speed controllers and brakes (critical for heavy loads and deep lanes)
  • •Entry guide and pallet separator at the pick face
Seismic Zone

Washington requires seismic engineering for pallet flow rack installations. All rack must resist lateral seismic forces per ASCE 7 and local building code. Budget for heavier baseplates, larger anchor bolts, and stamped engineering.

Pallet flow gives you high density with FIFO rotation — critical for perishable goods and lot-controlled inventory. Drive-in gives you high density at lower cost, but it's LIFO. If expiration dates matter, you need pallet flow. If they don't, drive-in is simpler and cheaper.

Did you know?

Washington state produces more apples than all other US states combined — roughly 10-12 billion apples per year. The cold storage infrastructure to keep those apples fresh from harvest in September through the following summer is one of the largest controlled-atmosphere storage networks in the world.

Frequently Asked Questions

What's the difference between pallet flow and push back rack?
Inventory rotation. Pallet flow is FIFO (first in, first out) — you load from the back and pick from the front. Push back is LIFO (last in, first out) — you load and pick from the same face. If your product has expiration dates or lot control requirements, you need pallet flow. If rotation doesn't matter and you just need density, push back is simpler and cheaper.
How many pallets deep can pallet flow go?
Practical range is 5-20 pallets deep, depending on pallet weight and consistency. Some systems go deeper, but lane reliability decreases as depth increases — more rollers mean more potential failure points. Most installations settle in the 8-12 pallet range.
Is pallet flow rack expensive?
Yes — it's one of the pricier rack systems per pallet position. The gravity conveyor beds, speed controllers, and engineering add significant cost over static rack. But in operations where FIFO is mandatory and density is critical (especially cold storage), the cost per stored pallet in a given footprint is often lower than the alternative of building more cooled space.
How many pallet flow rack suppliers are in Washington?
We currently list 3 companies offering pallet flow rack in Washington. This number grows as we expand our directory. Nearby states may have additional options.
Does pallet flow rack in Washington require seismic engineering?
Yes. Washington is in a seismic zone, so all rack installations — including pallet flow rack — must be seismically engineered per ASCE 7 and local building code. This means heavier baseplates, larger anchor bolts, and stamped engineering drawings. Budget 15-25% more for the seismic components.
Did you know?

Pallet flow lanes use the same style of sealed bearings you'd find in skateboard wheels — just rated for 3,000 lbs instead of a kickflip.
