Seattle Pallet Racking & Warehouse Solutions

Seismic Design Category::

Seattle sits directly above the Seattle Fault and in the shadow of the Cascadia subduction zone, two distinct seismic hazards. Typical industrial sites fall under Seismic Design Category D per ASCE 7-16, high seismic risk, with mandatory engineered anchorage and lateral bracing on all racking systems.

Engineering::

Every Seattle installation includes stamped seismic anchorage calculations, wedge anchors torqued to spec, and footplates rated to actual site loads. SDCI sees real numbers tied to your slab and soil conditions.

High-Piled Combustible Storage::

Anything stacked over 12 feet typically triggers a high-piled storage permit from the Seattle Fire Department. This is the most common fire-related permit for warehouse racking, and the one that most often catches operators off guard mid-project.

Sprinkler Coordination::

Racking cannot interfere with sprinkler coverage. If new racks change ceiling-to-pile heights, sprinkler design usually needs adjustment too. We prepare the commodity classification per NFPA 13 and coordinate directly with your sprinkler designer and the fire marshal so both packages clear together.

Load Capacity::

Every rack we install gets a capacity label rated to the actual configuration, not a generic spec sheet. The label tells your team and the inspector exactly what each level can hold.

Anchoring::

Slab anchorage is critical for any Seattle installation. We calculate anchorage specific to your concrete thickness, slab condition, and site soil class, then torque-test every anchor before turnover.

General Duty Clause::

OSHA Section 5(a)(1) requires employers to provide a workplace free from recognized hazards. Pallet rack violations are among the most common citations during industrial inspections, and financial penalties adjust annually for inflation. A documented, engineered system is the cleanest defense.

Ongoing Compliance::

We provide capacity labeling, safe-access design, and a maintenance handoff at the end of every install so your team knows what to inspect monthly and what to escalate. Recurring safety inspections are available as a service when you want a documented compliance trail.

Pre-Install Engineering Review::

Before any steel ships, our team audits your order against your site dimensions, forklift class, and pallet specs. We’ve caught customer measurement errors worth $1,000+ before they ever left our yard.

Post-Install Verification::

Once installed, the system is load-tested and labeled. SDCI conducts the final compliance inspection. We provide the documentation they need (stamped drawings, anchor torque records, capacity certifications) so the inspection passes the first review.

Zoning Compliance::

Seattle’s industrial and commercial zones generally permit warehouse racking without variance, but installations that change building occupancy classification adding mezzanine floor area, or shifting an S-2 warehouse toward S-1 high-hazard storage can trigger reclassification.

Site-Specific Checks::

Shoreline overlay zones near the Port of Seattle, Harbor Island, and Lake Union require additional environmental review. If your facility falls within a shoreline jurisdiction, we flag it early and route the package through the right SDCI reviewer.
