Heavy-Duty Longspan & Industrial Storage Assemblies
Precision-rolled cold steel profiles engineered to balance heavy static load capacities with manual picking accessibility across Southern California distribution channels.
Santa Ana Infill Logistics
Maximizing Cubic Utilization Under Southern California Footprint Pressures
As industrial real estate vacancy rates in Orange County hover near historic lows and square footage lease costs surge across Santa Ana, Costa Mesa, and Anaheim, enterprise operators can no longer afford horizontal storage inefficiencies.
Operating a manufacturing or distribution enterprise within the central corridor of Santa Ana, California—bounded by the I-5, SR-55, and SR-22 freeways—presents distinct structural and operational hurdles. Santa Ana serves as the backbone of Orange County's precision machining, medical device manufacturing, and high-velocity third-party logistics (3PL) fulfillment for goods entering through the Ports of Long Beach and Los Angeles. With industrial land premiums demanding over $1.75 to $2.20 per square foot NNN, warehouse owners face substantial financial consequences when floorspace is underutilized.
Longspan shelving serves as the critical engineering link between light-duty standard shelving and heavy, wide-aisle pallet racking. While traditional selective pallet racks are indispensable for forklift-handled unitized loads, manual picking operations handling non-palletized cartons, heavy automotive cores, biomedical assemblies, and aerospace tooling require unobstructed, hand-loaded clear spans. Our longspan manufacturing systems provide span lengths up to 96 inches without intermediary front column obstructions, enabling multi-tier catwalk implementations that multiply usable storage area within existing building clear heights.
Localized Applications
Engineered Deployment Across Santa Ana's Core Industrial Sectors
From cleanroom-compatible kitting shelves along the John Wayne Airport tech corridor to heavy-duty inventory pick towers in the Grand Avenue industrial district, our systems integrate seamlessly into specific local workflows.
Aerospace & Defense Precision Staging
Santa Ana and nearby Irvine house Tier-1 and Tier-2 aerospace subcontractors requiring strict particulate control, foreign object debris (FOD) mitigation, and segregated parts containment. Our longspan profiles utilize static-dissipative powder coatings and flush drop-in galvanized steel decking panels, eliminating wood fibers and debris while maintaining static capacities exceeding 1,800 lbs per beam pair for raw titanium bars, turbine housings, and aviation avionics modules.
Biomedical & Cleanroom Staging Modules
Orange County’s life science cluster requires sanitary storage compliant with FDA 21 CFR regulations. Our specialized longspan racks feature chemical-resistant, antimicrobial polyester finishes paired with open wire-mesh decks that facilitate laminar airflow. Seamless clip-in dividers allow precise SKU separation for high-value surgical instruments, diagnostic machinery, and cold-chain temperature-controlled dry storage units.
Automotive Aftermarket Core & Parts Logistics
Positioned near major transportation arteries like Harbor Boulevard and Warner Avenue, regional automotive aftermarket parts hubs deal with irregularly shaped exhaust components, brake rotors, and transmission casings. Our high-gauge step-beam profiles support localized shock loading, and our modular frame depth configurations (24" to 48") maximize pick accessibility for manual stock-pickers and inventory clerks.
High-Throughput E-Commerce Multi-Tier Pick Towers
As omni-channel retail distribution accelerates across Southern California, Santa Ana facilities utilize our vertical frame uprights to construct multi-level catwalk systems. Integrated with carton-flow roller tracks and pick-to-light sensors, our longspan systems allow small-parcel fulfillment centers to achieve rapid item retrieval rates without the structural footprint expansion of conventional mezzanine flooring.
Regulatory & Seismic Compliance
Navigating California Title 24, CBC 2022/2025, and High-Seismic Permitting
Every industrial shelving system erected within Santa Ana falls under the scrutiny of the City of Santa Ana Planning and Building Safety Division and the Orange County Fire Authority (OCFA).
The geographic proximity of Santa Ana to major active fault segments—including the Newport-Inglewood fault zone, the Whittier-Elsinore fault, and the San Andreas system—classifies the municipality under Seismic Design Category (SDC) D, E, or F depending on exact site soil profiles. Consequently, simple boltless shelving designs lack the lateral resistance and torsional stiffness mandated by state code.
Seismic Structural Design Provisions (ANSI MH16.1 / ASCE 7-16 / 7-22)
Our longspan framing components are calculated in full alignment with the Rack Manufacturers Institute (RMI) Specification for the Design, Testing and Utilization of Industrial Steel Storage Racks (ANSI MH16.1) as incorporated into Title 24 of the California Code of Regulations. When calculating Spectral Acceleration values ($S_{DS}$ and $S_1$), our engineering team conducts comprehensive base-moment calculations:
- Oversized Seismic Footplates: Uprights feature heavy-duty 3/8" or 1/2" thick baseplates laser-welded with multiple anchoring holes to disperse shear forces across concrete floor slabs without edge blowouts.
- Seismic Wedge & Adhesive Anchoring: Systems are engineered around post-installed Hilti HIT-HY 200 or Simpson Strong-Tie Strong-Bolt 2 anchors, specified for slab depths common to Santa Ana tilt-up industrial construction (typically 5" to 7" 3,000–4,000 PSI unreinforced or reinforced slabs).
- Swaged Upright Geometry & Stiffeners: Columns are roll-formed using high-tensile Q355B (ASTM A1011 Grade 50 equivalent) cold-rolled steel with reinforced return flanges to resist seismic buckling along the cross-aisle direction.
High-Piled Combustible Storage & OCFA Fire Protection (NFPA 13)
Under Santa Ana municipal guidelines, any storage rack exceeding 12 feet in height (or 6 feet for high-hazard commodities such as plastics, elastomers, or flammable liquids) requires a dedicated High-Piled Combustible Storage Permit. Crucial factors include:
- Flue Space Integrity: Maintaining continuous 6-inch transverse and longitudinal flue spaces between back-to-back rack runs to allow early smoke vent actuation and thermal penetration.
- Decking Openness: Utilizing galvanized wire-mesh decking with a certified open-surface ratio exceeding 50% to ensure unobstructed water penetration from ceiling ESFR (Early Suppression, Fast Response) fire sprinkler arrays down to lower storage tiers.
- Sprinkler Deflector Clearance: Calibrating maximum top-tier load heights to guarantee at least 18 inches (standard sprinkler) or 36 inches (ESFR sprinkler) of clearance below deflector heads across all warehouse bays.

Frequently Asked Questions
Santa Ana Warehouse Shelving & Procurement FAQ
Key structural, permitting, and logistics insights addressed directly by our material handling engineering team.
Does the City of Santa Ana require a building permit for installing industrial longspan shelving?
Yes. Under the City of Santa Ana Building and Safety Division guidelines, any commercial shelving or rack system over 5 feet 9 inches in height requires a structural building permit. If your overall system height exceeds 12 feet, or if you store high-hazard commodities (such as flammable aerosols, Group A plastics, or rubber tires), a High-Piled Combustible Storage permit is also mandated in coordination with the Orange County Fire Authority (OCFA). We provide complete permit submittal packages including California Professional Engineer (PE) stamped structural calculations, anchorage verification, and architectural floor plan layouts.
How do you engineer longspan shelving for Southern California's high seismic zones?
Our racks are designed in strict accordance with ANSI MH16.1 and California Building Code (CBC) Title 24 regulations. In Santa Ana, where site-specific spectral acceleration ($S_s$) regularly exceeds 1.5g, we calculate dynamic seismic response parameters based on your building's soil classification (typically Soil Class D). Our engineering includes enlarged baseplates (up to 6" × 8" × 3/8" or 1/2"), heavy-duty anchor bolt embedments (utilizing ICC-ES approved Hilti or Simpson anchors), heavier gauge roll-formed column profiles, and welded rear diagonal bracing to withstand earthquake vibrations without racking failure.
What is the difference between standard rivet shelving and industrial heavy-duty longspan shelving?
Standard rivet (or boltless) shelving typically uses 16-gauge angle posts and single-rivet or double-rivet horizontal shelf supports, maxing out at capacities between 300 to 600 lbs per tier over narrow 3-to-4 foot spans. Industrial longspan shelving utilizes heavy-duty roll-formed upright frames (similar to light pallet rack construction) with adjustable step beams spanning up to 8 feet (96 inches). Longspan supports uniform distributed loads from 1,200 to 2,400 lbs per beam pair, accommodates drop-in steel or wire-mesh decks, and can be integrated into multi-tier catwalks that standard rivet shelving cannot safely support.
What concrete slab thickness and PSI strength are required to anchor these racks?
For standard medium-duty to heavy-duty longspan installations under 12 feet tall, an existing 5-inch thick concrete slab with a compressive strength of 3,000 PSI is usually sufficient for our seismic anchoring calculations. For systems exceeding 12 feet, multi-tier picking towers, or when anchoring close to slab expansion joints, we recommend core drilling or slab radar testing to confirm slab thickness, rebar positioning, and sub-base stability. If local slab capacity is limited, our engineers can expand the footplate dimensions or adjust anchor embedment depths to satisfy shear and pullout safety factors.
How are shipments handled from your manufacturing plant to Santa Ana warehouses?
We manage direct export logistics via 40ft High Cube (40HC) ocean shipping containers entering through the Port of Long Beach or Port of Los Angeles. All components are tightly bundled, wrapped in protective moisture barriers, and steel-banded to heavy wood skids compliant with ISPM 15 standards. From the port, our logistics partners execute drayage delivery directly to your facility in Santa Ana, Costa Mesa, Anaheim, or Garden Grove, complete with liftgate or flatbed offloading coordination upon request.
Can longspan shelving be retrofitted or customized as our SKU profile changes?
Absolutely. Our longspan beams feature teardrop or slotted connector clips with 50mm (2-inch) vertical adjustment increments. Shelves can be quickly reconfigured without specialized tools. Furthermore, if you expand your facility, our standardized profiles allow add-on bays, upright extensions, garment hanging rails, or drop-in carton flow lanes to be retrofitted onto your existing framework without requiring a complete system replacement.
Which decking material is best for Orange County fire code compliance: wire mesh, particle board, or steel panels?
Galvanized wire mesh decking is strongly recommended for Santa Ana and Orange County installations. The Orange County Fire Authority (OCFA) enforces strict water dissipation rules for overhead fire sprinklers. Wire mesh decking provides an open surface area greater than 50%, enabling water from overhead sprinklers to reach lower storage levels during a fire event. Solid particle board is combustible and blocks water flow, frequently triggering expensive mandates for in-rack sprinkler systems. Drop-in perforated steel decking panels offer an excellent non-combustible alternative for heavy point-loads while maintaining required water drainage.
