Wide Span Structural Design & Steel Metallurgical Integrity

Bridging the operational gap between conventional light shelving and heavy pallet racking, wide span shelving delivers high linear load distribution across clear shelf bays from 1,200 mm to 2,700 mm.

In modern industrial storage architecture, Wide Span Shelving (also recognized across Marmara logistics sectors as long-span racking) serves as the primary structural system for non-palletized, manual-access goods requiring high load-bearing integrity. Constructed from structural-grade cold-rolled Q235B mild carbon steel (mechanically equivalent to European EN 10025 S235JR), our upright upright frames feature an optimized multi-bend Omega (Ω) profile. This cold-roll-formed cross-section increases the system’s radius of gyration, significantly elevating torsional rigidity and buckling resistance against eccentric and dynamic loads.

The structural beam levels employ twin-flanged step beams or heavy-gauge box profiles secured to vertical frames via CNC-punched, 50 mm or 75 mm pitch teardrop/keyhole hook connectors. Each beam end is fitted with integrated steel safety spring pins that withstand upward shear forces exceeding 5,000 N, preventing accidental beam dislodgement caused by forklift impact or manual handling snags. Depending on localized operational needs, shelf decking is configured with high-gauge drop-in galvanized steel panels, heavy-duty wire mesh decking with under-deck hat stiffeners, or high-density particle panels to accommodate point-load concentrations without permanent plastic deformation.

Deflection criteria within our structural engineering calculations adhere to European standard FEM 10.2.02 and EN 15512 specifications. Maximum allowable beam deflection under full working load is strictly limited to 1/200th of the clear span length (L/200), ensuring zero operational interference during continuous warehouse order-fulfillment and complete structural margin of safety.

Critical Structural Safety

Seismic Engineering for the North Anatolian Fault (NAF) Zone

Racking in Istanbul requires structural survivability. We design every upright system in strict alignment with Turkish Building Earthquake Code (TBDY 2018) and TS EN 16681 guidelines.

Because Istanbul straddles seismic zones characterized by high peak ground acceleration (PGA up to 0.4g–0.5g along the Marmara coast), warehouse storage racking cannot be treated as simple static furniture. In an earthquake event, racking acts as an active structural frame carrying immense dynamic masses. Inadequate anchoring or substandard beam-to-column connections inevitably result in progressive collapse, threatening lives and business continuity.

To eliminate seismic failure risks, our technical department conducts finite-element response spectrum analyses tailored to the exact geotechnical classification of your Istanbul facility (from ZD to ZF soil categories under TBDY 2018). Our high-risk mitigation package incorporates:

1. Ductile Upright Baseplates & Heavy Chemical Anchors: Base assemblies feature laser-cut 8 mm to 12 mm Q345B footplates with expanded load footprints. Anchoring utilizes M12–M16 seismic-grade chemical injection studs rated to dynamic concrete pull-out values exceeding 45 kN.

2. Engineered Cross-Aisle & Down-Aisle Bracing: Vertical bracing towers utilizing calibrated C-channels and tensioning turnbuckles dissipate cyclic lateral acceleration, controlling inter-story drift and preventing resonance catastrophic failure.

3. Energy-Dissipating Semi-Rigid Beam Connectors: High-ductility 5-finger connector claws deform plastically during extreme ground motions without instantaneous fracturing, absorbing seismic kinetic energy while keeping shelf inventories securely captive.

Market Dynamics

Key Strategic Trends Reshaping Turkish Warehousing

How regional nearshoring initiatives and transcontinental freight corridor expansions are driving the demand for modular, high-density wide span racking solutions.

The Nearshoring Pivot to Marmara

European multi-nationals are shifting supply chains away from distant origins into Turkey to capitalize on short transit times into the EU. This influx requires modular, quickly deployable wide span shelving that can be reconfigured dynamically as production runs fluctuate.

Severe Urban Land Constraints

With industrial land leasing rates escalating sharply across Istanbul's inner rings, operators cannot expand horizontally. Multi-tier wide span mezzanine systems are surging in demand, turning standard 7-meter to 10-meter clear height buildings into triple-level manual order picking factories.

Hybrid Automation & WMS Sync

Istanbul logistics operators are merging manual wide span picking levels on lower tiers with high-bay pallet racking and automated shuttle systems above. Seamless integration requires precise millimeter fabrication tolerances and standardized SKU bin interfaces.

Buyer Guidance

Istanbul Procurement & Technical FAQ

Direct answers to the most common engineering, customs clearance, and structural compliance questions asked by procurement directors in Turkey.

How does wide span shelving compare structurally with pallet racking?
Wide span shelving is engineered for medium to heavy hand-loaded products or boxed bulk SKUs (typically 300 kg to 1,500 kg per beam level) where forklifts are not driven into the racking bay. Heavy-duty pallet racks are built for unitized pallet loads (1,000 kg to 4,500 kg per level) requiring forklift mast entry. In many Istanbul warehouses, wide span is integrated into lower levels with selective pallet storage stacked above.
What seismic load calculations are provided for facilities in Gebze or Tuzla?
For projects in high-seismic zones along the Marmara fault line, our engineering department performs full seismic modal analysis conforming to TBDY 2018 (Turkish Building Earthquake Regulation) and European standard TS EN 16681. We supply complete calculation sheets detailing floor shear forces, horizontal drift limits, anchor bolt tensile forces, and dynamic safety margins.
What documentation is supplied for Turkish Customs clearance at Ambarlı Port?
Every export shipment includes a certified Commercial Invoice, Packing List with accurate container weight distribution, Ocean Bill of Lading (B/L), Certificate of Origin, and European CE Declaration of Conformity. Material test certificates (MTC EN 10204 Type 3.1) validating Q235B steel chemical and mechanical properties are delivered with shipping manifests.
Can shelf levels be adjusted after installation as warehouse SKUs change?
Yes. All wide span uprights are CNC-punched with continuous teardrop or slotted pitch hole patterns spaced at 50 mm or 75 mm intervals. Beams can be unclipped and repositioned in minutes without unbolting structural frames or disturbing adjacent bays, allowing operations to adapt quickly to changing SKU packaging sizes.
What surface treatment is applied to combat Istanbul's maritime humidity?
Structural members undergo an 8-stage automated pre-treatment line, including high-pressure chemical degreasing, acid rust removal, and zinc-phosphate passivation, followed by electrostatic epoxy-polyester powder coating cured at 200°C (film thickness 60–80 μm). For open-air, cold storage, or coastal facilities near the Marmara shore, hot-dip galvanized steel panels and frames are available.
What is the typical production and shipping transit time to Istanbul?
Standard project manufacturing lead times range from 15 to 25 days depending on project tonnage. Ocean container shipping from Guangzhou to Ambarlı or Haydarpaşa ports takes approximately 22 to 28 days via direct vessel sailings. Our engineering team delivers 2D and 3D installation drawings beforehand so your local erection team can prepare floor slabs in advance.
