Direct from our ISO 9001 and CE certified manufacturing facility to New England logistics facilities along I-95, I-495, and the Massachusetts Turnpike. Every unit is engineered for rigid structural integrity under extreme tire payload densities.
Designing industrial tire storage racking for Massachusetts commercial facilities requires navigating the intersection of extreme floor loading densities, local seismic zone codes (780 CMR), and stringent NFPA 13 rubber tire fire safety requirements.
Analysis of Cold-Formed High-Tensile Steel (Q235B/Q355B vs. ASTM A36/A1011) Under Cyclic Temperature Fluctuations
Warehousing in the Boston metropolitan area—from Chelsea and South Boston to Framingham and Worcester—endures extreme seasonal temperature swings ranging from sub-zero coastal blizzards in January (-15°C) to humid, salt-air summers (+35°C). Under ambient conditions, steel storage frameworks experience thermal expansion and contraction that exacerbate mechanical deflection across long-span beam levels.
Our manufacturing plant fabricates tire racking uprights and step beams using certified Q235B and high-yield Q355B structural steel (equivalent to ASTM A36 and ASTM A572 Grade 50). Upright profiles undergo precision continuous roll-forming to ensure uniform cold-work hardening across flange bends. This geometry increases the moment of inertia without adding deadweight, maintaining a safety factor of 1.67:1 under full rated load as dictated by ANSI/RMI MH16.1 specifications.
| Mechanical Parameter | HEDA Standard (Q355B) | ASTM Equivalent | Engineering Impact |
|---|---|---|---|
| Yield Strength (Fy) | ≥ 355 MPa (51.5 ksi) | ASTM A572 Gr 50 | Resists dynamic impact during forklift load placement |
| Tensile Strength (Fu) | 470 – 630 MPa | ASTM A572 | Prevents frame buckling under multi-tier tire racking |
| Elongation (δ5) | ≥ 21% | ASTM A36 (20%) | Ductility prevents brittle failure in freezing New England winters |
| Deflection Limit | L / 240 Service Load | ANSI/RMI MH16.1 | Zero beam binding, guarantees unimpeded tire rolling & picking |
| Salt Spray Resistance | 500+ Hours (ASTM B117) | Powder Spec | Complete defense against coastal salt fog along Boston logistics hubs |
Seismic Base Anchor Embedment, Concrete Slab Dynamics & Structural Calculation Checks
Under the Massachusetts State Building Code (780 CMR 9th and 10th Editions, incorporating IBC and ASCE 7 standards), the Boston region is categorized within Seismic Design Categories B and C. Storage rack systems exceeding 8 feet in height are classified as distinct steel building structures and must be engineered with explicit base plate dimensions, certified anchor embedments, and seismic diagonal bracing arrays.
Because rubber tires are non-rigid, dynamic payloads that alter their natural frequency under lateral earth tremors, standard static load calculations are insufficient. Heda Shelves supplies full stamped engineering design packets for every Boston installation, calculating spectral acceleration parameters (Ss and S1 values) specific to Middlesex, Suffolk, and Essex counties. Our baseplates are enlarged to 150mm × 150mm × 8mm minimum thickness, pre-punched for heavy-duty wedge mechanical anchors embedded into minimum 4,000 PSI reinforced concrete slabs.
Flue Space Architecture, In-Rack Sprinkler Clearances & Combustion Suppression Matrix
In the NFPA 13 standard (Standard for the Installation of Sprinkler Systems), rubber tires are categorized among the most severe fire risks—exceeding Class IV commodities and falling into the Group A Plastics / Rubber Tire classification due to their extreme British Thermal Unit (BTU) heat release rates and petroleum-based smoke generation. Boston fire marshals enforce rigorous compliance regarding rack structure flue spaces:
Longitudinal and Transverse Flue Clearance: Solid decking is prohibited in high-pile tire storage exceeding 12 feet unless dedicated in-rack sprinkler lines are incorporated at every tier. Our industrial tire racking uses open-aperture welded wire mesh decking or dual-rail steel tire cradles. This layout maintains a minimum 6-inch continuous vertical transverse flue space and 6-inch longitudinal flue space between back-to-back rack rows, allowing sprinkler suppression water to penetrate directly to early-stage smoldering ignition points.
Tire Stacking Orientation: On-tread (vertical rolling position) vs. on-side (horizontal laced/stacked) configurations dictate fire sprinkler discharge densities. Our selective and dynamic tire racks are custom engineered to stabilize on-tread storage with curved beam contours, preventing horizontal tire cascading during emergency water discharge while meeting city of Boston municipal safety permits.
From port drayage terminals along Boston Harbor to high-throughput regional 3PL fulfillment operations down the I-95 logistics spine, our industrial racking systems solve real-world floor space bottlenecks.
Boston's extensive municipal transport infrastructure, Logan International Airport GSE (Ground Support Equipment), and regional commercial delivery fleets require instant access to heavy commercial truck, van, and bus tire reserves. High-density 4-tier and cantilever units allow fleet workshops in South Boston, Dorchester, and Everett to organize heavy 22.5-inch and 24.5-inch commercial tires with zero floor clutter.
Massachusetts drivers encounter harsh winters requiring biannual seasonal changeovers between all-season and dedicated studded/winter tires. Automotive dealership groups across Newton, Norwood, and Woburn utilize our multi-tier rack-supported mezzanine platforms to operate lucrative "tire hotel" storage services, doubling storage capacity without expanding building footprint.
Regional distributors situated in Marlborough, Franklin, and Lawrence supply retail tire dealers throughout Massachusetts, Rhode Island, and New Hampshire. Utilizing our heavy selective pallet racks and gravity flow roller systems, wholesale DCs handle full container loads direct from Port of Boston Conley Terminal, ensuring continuous FIFO rotation and zero sidewall distortion.
Real estate economics in Eastern Massachusetts demand maximum cubic utilization, seismic compliance, and modern warehouse mechanization to offset rising operational overheads.
Greater Boston has one of the most constrained industrial markets in North America, driven by life sciences conversion and tight zoning around Route 128. With industrial warehouse space commanding record triple-net rates, operators cannot afford floor-stacked tire inventories. Vertical racking converting 28-to-36-foot clear heights into multi-tier storage increases pallet capacity per square foot by up to 320%.
Massachusetts leads New England in zero-emission vehicle adoption. EV replacement tires are up to 25% heavier than conventional internal combustion tires due to specialized sound-deadening foam, thicker sidewalls, and reinforced bead construction required for heavy battery torque. Heda Shelves reinforces all beam calculations to accommodate this increased load density without beam sag.
New England distributors are increasingly bypassing domestic warehouse equipment resellers who apply 40–60% dealer markups. By establishing factory-direct supply agreements with certified manufacturers like HEDA Shelves, logistics directors secure direct engineering support, custom dimension tailoring, and optimized ocean container logistics landing directly at Port of Boston Conley Terminal.

Orders ship in 40ft High Cube (HC) ocean containers directly from South China ports to the Port of Boston (Paul W. Conley Container Terminal) or via the Port of New York & New Jersey with expedited bonded rail/drayage into Massachusetts. We prepare customized container stowage diagrams to maximize internal cubic fill, preventing shipping damage while lowering landed freight cost per bay.
Our designs use open welded wire decking with >70% vertical water permeability, or contoured dual-rail tire supports that leave open transverse and longitudinal flue spaces. This architecture allows emergency fire sprinkler water to discharge unimpeded directly between tire tiers, preventing local fire marshal code citations during building walkthroughs.
Yes. Because we control all roll-forming and punching processes in-house, beam lengths, cradle depths, and load capacities are manufactured to your specific mix of tire diameters (from 15-inch passenger treads up to 55-inch agricultural and construction OTR tires). Step-beam increments adjust at 50mm or 75mm intervals to eliminate wasted vertical air space.
Precision manufacturing in our Guangzhou plant takes approximately 15 to 22 business days following CAD drawing sign-off. Ocean transit to Conley Terminal or Port of NY/NJ ranges between 26 and 32 days. We recommend initiating engineering consultations 8 to 10 weeks before your facility's planned operational commissioning date.
Every shipment includes numbered piece tags, comprehensive 3D assembly sequence blueprints, anchor hole patterns, and beam safety-pin alignment instructions. Clients can deploy their preferred local Massachusetts union or open-shop rigging contractors, or we can coordinate remote video supervision with our lead project engineers.
For standard 4-to-5 tier industrial tire racks (up to 20 feet high), an unreinforced or wire-mesh reinforced 5-inch concrete slab with a 3,000–4,000 PSI rating is typically sufficient. For taller automated ASRS systems or multi-level mezzanines exceeding 24 feet, our structural engineers evaluate slab thickness, sub-base soil compaction, and anchor pull-out ratings before establishing baseplate footprints.
