Cantilever Rack in Seattle, WA
Seattle cantilever rack projects need a plan that fits the building and inventory, not only a list of components.
Cantilever rack exists because pallet rack has a front beam and long material doesn't care about pallets. Arms extend out from a column with no obstruction across the front, so lumber, pipe, tube, bar stock, sheet goods, and furniture load from the side and come off the same way, without lifting over anything.
Choose it whenever product length, not weight or SKU count, is what's driving the storage problem - the alternative is usually leaning bundles against a wall or floor-stacking them where forklifts have to work around them. Arm length, capacity, and column spacing get set by the bundles you actually handle, not a generic length.
We quote single-sided runs for a wall and double-sided runs for open floor, both with the layout attached so arm count and levels are settled before steel is ordered.
Why Seattle Warehouses Work With Us
Older infill buildings leave limited room for additional receiving lanes; dock access and column spacing must be measured before storage depth is chosen. Around SODO, Georgetown and the Duwamish corridor, the cantilever rack decision starts with how the building is used today: where loads arrive, which orders need immediate access and where staff or equipment share a route. Pipe, lumber and maintenance stock in South Park can occupy the floor needed to turn delivery trucks and prepare building-material orders.
port logistics, food distribution and urban fulfillment all use space differently. Access around Port of Seattle terminals, East Marginal Way S and I-5 matters to the delivery or transfer plan, but the design still comes back to bundle lengths, weight distribution, support points, arm reach and handling-equipment clearances. During the free consultation we compare usable positions with operating space, and explain what changes if the inventory mix grows or a handling truck is replaced.
Seattle Pallet Racks is part of Warehouse Equipment & Supplies Co. Your Seattle team has a point of contact for layout revisions, the written scope and scheduling questions. We work through practical details before material arrives, including where each delivery can be staged without blocking your dock. After handover, keep the approved drawing and contact us before changing loads, levels or the layout.
How Cantilever Rack Works in Seattle
Columns and anchored bases
Upright columns sit on bases anchored to the floor. Base depth is set by load and arm length so the run stays stable even under an off-center pick.
Arms at adjustable heights
Arms bolt or pin into the column at set increments and move as your product mix changes. Straight arms suit boxed goods; inclined arms with a lip hold round or loose stock in place.
Column spacing against sag
Spacing between columns is set so bundles don't sag between arms. A common starting rule places arms about half the load length apart, with the ends overhanging evenly.
Single-sided or double-sided
Single-sided runs go against a wall. Double-sided runs stand in open floor and load from both faces, doubling capacity per base without doubling the footprint.


Where It Fits Best
What We Need to Design It
- What are the dimensions of the product being stored, length included?
- What's the typical weight per bundle?
- Straight arms or inclined arms - do you need lips to hold round stock?
- Single-sided along a wall, or double-sided in open floor?
- What's the clear height and the reach of your handling equipment?
What a Project Includes
A cantilever rack project in Seattle begins with a review of bundle lengths, weight distribution, support points, arm reach and handling-equipment clearances. We use building drawings and verified measurements to establish usable height, obstructions, column positions and access routes. For a site around Port of Seattle terminals, receiving windows and staging areas are included in that conversation so the installation plan is grounded in how your operation runs.
Columns, bases, arms and bracing are itemized. Single-sided runs and double-sided runs are compared against the space available for handling long loads. Arm levels follow bundle depth, while support spacing is checked against sag and the material supplier's guidance. Round stock needs appropriate retention; an arm lip is not a replacement for safe load placement.
You receive a layout, a counted storage or picking plan and an itemized scope that separates equipment, delivery and installation. New material is specified for any additional rack. Experienced installation crews we schedule and manage follow the agreed layout, and the rack is anchored to the floor. Our team handles the permit side for you.
Confirmation that bases are anchored to the floor, column alignment, arm elevations and load ratings are reviewed before material is placed. Outdoor use requires a separate review of exposure and site conditions. Work can be sequenced by agreed zones when the site allows it. Your Seattle operations lead confirms which routes must stay open and when inventory may enter completed areas. The handover records the final configuration, operating limits and remaining actions, giving your team a practical reference for future changes rather than only a delivery receipt.
