EnglishEspañolDirect-from-factory modular pallet racks, automated shuttles, and rack-supported intermediate mezzanine platforms designed for high-throughput American logistics.
Eliminating domestic dealer markups while maintaining full adherence to American RMI standards, structural steel integrity, and precision layout integration.
Designing, engineering, and fabricating mission-critical warehouse storage frameworks since 2001 across North America and 5 continents.
From rack-supported catwalk mezzanines to AS/RS and teardrop roll-formed configurations produced with automated roll-forming lines.
Every bay is calibrated to floor loading ratings from 500 kg/m² to over 1,500 kg/m², fully compliant with ASTM and RMI specifications.
Certified steel grades with automated electrostatic powder coating that resists chemical corrosion, forklift impact, and peel stress.
Our bilingual structural engineers deliver full 2D AutoCAD and 3D architectural layout calculations within 8 hours of drawing submission.
In logistics capital hubs like Chicago, Illinois, logistics facilities encounter some of the highest industrial real estate rental premiums across the Midwest. Rather than executing costly real estate acquisitions or ground expansions, forward-thinking warehouse managers leverage vertical cubic space through Rack-Supported Mezzanine Systems.
Unlike conventional freestanding structural steel platforms—which rely solely on heavy wide-flange I-beams and dedicated structural columns—rack-supported mezzanines integrate storage racking frames as the primary structural supports for the intermediate decking. This dual-purpose methodology provides unprecedented structural stiffness and eliminates redundant framework expenses.
| Engineering Attribute | HEDA Rack-Supported Mezzanine | Standard Structural I-Beam Platform | Single-Level Heavy Duty Pallet Racks |
|---|---|---|---|
| Space Utilization Ratio | Up to 220% of Original Footprint | 100% to 180% (Clear span below) | Limited strictly to floor clearance |
| Foundation Slab Load Concentration | Evenly distributed along continuous baseplates | High point loads on column footings | Standard point loading per post |
| Average Capital Outlay (CAPEX) | 30%–45% Lower Overall Material Cost | High structural steel mill fabrication cost | Low initial, but high real estate expansion cost |
| Material Standard & Yield Strength | Certified Q235B cold-rolled profile (Yield ≥ 235 MPa) | ASTM A36 / A992 Structural Steel | Q235B cold-rolled steel profiles |
| Integrated Storage Configuration | Immediate upper & lower picking/pallet slots | Requires secondary independent shelving racks | Standard single-plane vertical racking only |
| Chicago Building Permitting Viability | Exempt from certain interior property tax reclassifications | Often taxed as permanent structural building addition | Standard equipment equipment installation |
The Greater Chicago metropolitan region—spanning Cook County, DuPage County, Will County, and Lake County—forms North America's freight crossroads. Freight density, combined with brutal winter temperature swings and aggressive local building safety mandates, necessitates robust storage engineering.
Facilities along Elk Grove Village, Des Plaines, and Bensenville manage high parcel turnaround. Space comes at a massive premium. Our rack-supported catwalk platforms provide manual pick-and-pack modules on the intermediate level while retaining high-bay pallet staging directly below, enabling same-day e-commerce shipping fulfillment.
The major mega-distribution facilities serving the central U.S. handle multi-SKU retail replenishment. HEDA heavy-duty rack-supported platforms integrate automated pallet drops, gravity carton flow tracks, and heavy bar grating to support continuous walk-behind pallet jacks and hydraulic sorting cart traffic without floor flexure.
With Chicago serving as the epicentre for cold-chain grocery wholesalers, freezing cubic costs are exponential. By engineering high-density multi-tier platforms finished in high-adhesion anti-condensation powder coatings, cold-storage operations double their frozen storage tonnage inside existing refrigeration perimeters.
While northern Illinois is traditionally categorized with low-to-moderate seismic activity, Chicago municipal structural standards require rigorous calculations under ASCE 7 and RMI MH16.1. HEDA supplies enlarged footing baseplates with dual Hilti wedge anchor configurations.
City of Chicago Fire Prevention Code mandates clear vertical water penetration. HEDA incorporates minimum 50% open-area electro-forged steel bar grating or drop-in perforated steel decking, allowing automatic in-rack sprinkler discharge to penetrate lower levels.
All staircases, kickplates, and edge kick-rails conform to OSHA 1910.28 and IBC standards. Stair towers feature 7-inch risers, 11-inch treads, safety yellow non-slip nosings, and dual continuous handrails to guarantee worker safety during rapid shift turnovers.
Shipping from our Guangzhou factory directly to the Chicago railhead (BNSF Logistics Park Chicago or Union Pacific Global IV) is handled via optimized 40ft High Cube containers, knocked-down completely to minimize ocean freight cubic meters and reduce handling damage.
Our engineering design protocol incorporates RMI (Rack Manufacturers Institute) standard MH16.1, International Building Code (IBC) structural provisions, and OSHA fall protection standards. For projects requiring municipal plan-check approval in Cook County or Will County, our export team supplies stamped structural calculation packets, anchor pull-out ratings, and AutoCAD layout drawings.
We strictly utilize certified Q235B cold-rolled structural steel (yielding physical properties equivalent to ASTM A36). All structural uprights, shelf beams, and mezzanine cross-ties undergo a 9-stage phosphate wash before receiving an upgraded electrostatic polyester-epoxy powder coating cured at 200°C. This provides superior corrosion resistance against winter salt mist tracking and sub-zero condensation.
Our intermediate mezzanine walking decks are engineered from 60 PSF (light manual maintenance) up to 150 PSF (heavy pallet jack staging), which translates to 300 to 1,000+ kg/m². Standard lower rack levels can accommodate up to 4,500 kg (9,920 lbs) per pair of beams, tailored precisely to your standard GMA 48"x40" pallet loads.
By engineering fully knock-down bolted upright frames and nested structural deck panels, HEDA achieves ultra-high container cubing efficiency. A single 40ft High Cube container typically holds between 22 and 26 metric tons of structural systems. Even including trans-Pacific freight and Chicago intermodal rail transfer, landed costs are routinely 25% to 40% below domestic US steel platform fabricators.
Depending on fire safety mandates and operational traffic, we provide galvanized open bar grating (for optimum sprinkler spray penetration and natural lighting), heavy-duty diamond checker steel plates (for smooth rolling carts), or high-density tongue-and-groove resin-coated flooring atop cold-formed B-deck profiles for cost-sensitive office integrations.
Every system ships with numbered component tags corresponding directly to comprehensive 3D isometric installation blueprints and step-by-step video manuals. Local Chicago rigging and millwright teams can assemble the system using basic bolted connections without field welding. Alternatively, HEDA can deploy technical field supervisors directly to your site to guide your local labor crew.
