Push Back Pallet Rack Suppliers in Washington — 4 Companies

Push back rack gives you 2-6 pallets deep in a LIFO configuration, all loaded and retrieved from the same aisle face. Each pallet sits on a nested cart; when you push a new pallet in, it nudges the ones behind it back on inclined rails. Pull a pallet out, and the next one rolls forward. No driving into the rack structure required. 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 Push Back Rack

  • You need more density than selective rack but don't want forklifts driving into the structure
  • LIFO rotation is acceptable for your product
  • You have multiple SKUs that each need 2-6 pallets of depth
  • Your facility has limited aisle space and you need to maximize storage per face
  • You want a higher-density option that's less prone to forklift damage than drive-in

Key Specs to Ask About

  • Lane depth (2, 3, 4, 5, or 6 pallets deep)
  • Cart type and capacity (steel or poly, rated per pallet weight)
  • Rail pitch (slope angle — determines gravity return speed)
  • Pallet weight range (affects cart and rail sizing)
  • Rack frame type (structural is common for push back due to concentrated loads)
  • Safety stops and lane guides
Seismic Zone

Washington requires seismic engineering for push back 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.

Push back is LIFO, shallower, and cheaper. Pallet flow is FIFO, goes deeper, and costs more. If your product has expiration dates or lot control requirements, pallet flow is the answer. If rotation doesn't matter and you just need density from the aisle face, push back is simpler.

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

How many pallets deep can push back go?
Most push back systems go 2-6 pallets deep. Beyond 6, the nested cart stack gets complex and the forces involved increase significantly. If you need more than 6 deep, pallet flow (for FIFO) or drive-in (for LIFO) are better options.
Is push back rack safe?
Yes, when properly designed and maintained. The carts are guided on rails with positive stops at the pick face to prevent runaways. Compared to drive-in rack (where forklifts operate inside the structure), push back is actually safer because the operator never enters the rack.
Can I mix push back and selective in the same system?
Absolutely — and it's a common design. Put your high-volume, low-SKU items on push back lanes and your high-SKU, low-volume items on selective bays. Many facilities use push back in the lower levels with selective on top for pick faces.
How many push back rack suppliers are in Washington?
We currently list 4 companies offering push back rack in Washington. This number grows as we expand our directory. Nearby states may have additional options.
Does push back rack in Washington require seismic engineering?
Yes. Washington is in a seismic zone, so all rack installations — including push back 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?

Push back carts ride rails pitched at about 3 degrees — the same slope as a wheelchair ramp. But instead of a person in a chair, it's a 2,800 lb pallet acting like a gravity-powered bobsled.
