Pallet Racking Systems in Hillsboro, OR

Seismic Design Category:

Section 1705.13.7 of the 2022 Oregon Structural Specialty Code calls out steel storage racks and steel cantilevered racks 8 feet in height or greater that are assigned to Seismic Design Category D. The category is set per address from site class and soil conditions, so it is confirmed for your building rather than assumed from the city.

Engineering:

Frame capacity and base anchorage are calculated to ASCE 7 design loads for the assigned category. The City of Hillsboro Building Division has enforced seismic design standards on new construction and alterations since 1974, so plan reviewers here expect the calculations to be complete on the first pass.

High-Piled Combustible Storage:

In Hillsboro, a specific permit is required under the Oregon Fire Code when combustible materials are stored over 12 feet in height (or 6 feet for high-hazard commodities like plastics, tires, or lithium batteries) across an area exceeding 500 square feet. The application must be submitted to Hillsboro Fire & Rescue via the city’s Permit Portal and include a detailed floor plan, commodity classification matrix, exact storage heights, and structural engineering calculations (including seismic design, as this region requires specific earthquake bracing).

Sprinkler Coordination:

Rack row layout, transverse and longitudinal flue spaces, and decking type all have to match the building’s existing sprinkler design before the layout is final. The specific Hillsboro fire review thresholds and submittal requirements are triggered automatically for any racking system categorized as high-piled storage (12+ feet). Submittals must be routed through the City of Hillsboro Permit Portal and require a fire protection plan reviewed by an Oregon-licensed fire protection contractor or engineer. This submittal must strictly verify that flue spaces (typically requiring a 6-inch minimum longitudinal flue), ceiling clearances, and solid decking limits comply with NFPA 13 and Hillsboro Fire & Rescue standards, to determine whether the existing ceiling sprinklers are adequate or if in-rack sprinklers must be added.

Load Capacity:

Beam and upright capacity is specified per level against the actual pallet weight and loading pattern, following ANSI MH16.1 design practice. Rated capacity is posted on the system so operators are not estimating at the fork.

Anchoring:

Every upright is anchored to the slab at the spacing shown on the stamped drawings. Slab thickness and condition are verified on site before anchor type and embedment are selected, since an anchor rated for 6 inches of concrete does nothing in 4 inches.

General Duty Clause:

OSHA’s General Duty Clause requires employers to provide a workplace free of recognized hazards. A bent upright or a missing safety clip in an active aisle is a recognized hazard, and it is what an inspector looks at first.

Ongoing Compliance:

Posted load capacity labels, documented inspections, and repair records are the paperwork that gets requested during an inspection. We leave written documentation after every walkthrough so the file is current.

Pre-Install Engineering Review:

Before any steel ships, our team audits your order against your site dimensions, forklift class, and pallet specs. We catch specification errors before they leave our facility – and we document everything so your receiving team knows exactly what to expect at the dock.

Post-Install Verification:

After install, our crew checks anchor placement, beam engagement, and plumb against the approved drawings, then confirms the posted capacity matches what was engineered. Anything out of tolerance is corrected before the first pallet goes in.

Zoning Compliance:

Interior rack in an existing Hillsboro warehouse rarely changes zoning status. Outdoor racking, added mezzanine floor area, or a change in how the building is used can pull a zoning review at the City of Hillsboro alongside the building permit.

Site-Specific Checks:

Occupancy classification and approved use are checked against the proposed storage before submittal. In Washington County’s industrial parks, tenant improvements in multi-tenant buildings are the common place where the approved use and the actual storage plan drift apart.
