As Portugal transforms into a premier southwestern European logistics gateway—driven by massive intermodal expansions at the Port of Sines, the high-throughput Lisbon-Azambuja-Carregado logistics spine, and automated distribution hubs surrounding Greater Porto—procurement directors require robust, load-tested storage infrastructure. Our high-precision Longspan Shelving and Warehouse Racking systems provide unparalleled structural integrity, rapid assembly modularity, and compliance with stringent European standards (EN 15512, EN 15620, and Eurocode 8 seismic norms).
Longspan shelving bridges the operational gap between light-duty slotted angle systems and full-scale heavy pallet racking. Our profiles are precision cold-rolled from high-grade structural coil steel, featuring 50mm pitch punchings for total vertical configurability.
All beam calculations adhere to EN 15512 standards with a maximum permissible elastic deflection of L/200 under Uniformly Distributed Load (UDL). Uprights utilize a modified omega profile cross-section with multi-directional return bends, ensuring exceptional torsional rigidity against inadvertent forklift strikes and seismic horizontal force components.

Continuous roll-formed omega geometry with 11 structural bends provides high strength-to-weight ratios and dynamic load absorption.
Heavy-gauge 3-claw and 4-claw beam end connectors secured with high-visibility zinc safety pins to eliminate dislodgement risks.
Drop-in stepped beams accept hot-dip galvanized steel panels, perforated fire-sprinkler wire decks, or 25mm structural particleboard.
Electrostatic thermosetting epoxy-polyester powder coating (70-90μm) tested to 500-hour salt spray resistance for coastal Iberian ports.
From the specialized automotive corridors of the Setúbal Peninsula to the thriving agro-industrial heartlands of the Alentejo, our longspan systems solve acute storage constraints across distinct regional supply chains.
E-Commerce & Retail Fulfilment: As the primary logistics backbone serving metropolitan Lisbon, the Azambuja and Castanheira do Ribatejo distribution hubs require multi-tier pick towers. Longspan systems maximize vertical cubic space, enabling simultaneous batch-picking across tens of thousands of fast-moving SKUs.
Textile, Footwear & Hardware: Serving industrial estates in Vila Nova de Gaia, Maia, and Guimarães. Our wide-span open frames accommodate un-palletized bolt rolls, hanging apparel modules, and packaged metal components, providing instant visual inventory access for regional exporters.
Automotive Tier-1 & Tier-2 Supply: Surrounding the Autoeuropa manufacturing nexus, facilities require rugged shelving for sequenced KLT bins, wire baskets, and heavy stamping tooling. Heavy-duty longspan racks provide high capacity without the footprint of heavy structural pallet racking.
Viticulture & Cork Warehousing: Specialized dry-storage buffer facilities for bottling glass, natural cork closures, packaging cartons, and aged reserves. Galvanized decking configurations resist cellar humidity while safely supporting dense case-pack configurations.
Strategic nearshoring shifts within the European Union have positioned Portugal as an ideal production and logistics near-border base. Warehouse operators are rapidly upgrading static racking to reconfigurable, structurally certified modular infrastructure.
With deep-water port expansions at Sines, international logistics operators are constructing mega-consolidation hubs. Knockdown longspan shipments directly containerized to Sines or Leixões eliminate intermediaries, cutting logistics setup costs significantly.
Southern Portugal and the Lisbon metropolitan region feature moderate to high seismic risk classifications. Industrial installations must be calculated under Eurocode 8 with reinforced baseplates, heavy wedge anchors, and rear vertical cross-bracing.
European corporate sustainability directives incentivize long-lifecycle steel racking. Our high-tensile hot-rolled coils are fully recyclable, and low-VOC powder coating processes align with Portuguese ESG requirements for green building certifications.
Portuguese distribution centers are blending wide-span manual picking aisles with autonomous mobile robots (AMRs) and automated picking carts, necessitating wide, level aisle designs with robust collision floor guards.

Shipments arriving at Portuguese maritime ports (Port of Leixões or Port of Lisbon/Setúbal) are cleared under EU Common Customs Tariff code (TARIC) 73089098 for steel structures and racking components. Portuguese companies registered with a valid VIES VAT number can utilize the reverse charge mechanism (IVA autoliquidação na importação) under Portuguese Decree-Law, minimizing upfront cash flow burdens.
Our export logistics documentation includes certified commercial invoices, packing lists with net/gross weights, certificates of origin, and ocean bills of lading (B/L) for seamless clearance through Portuguese Customs (Autoridade Tributária e Aduaneira).
Yes. All structural calculations adhere to EN 15512 (Steel static storage systems – Adjustable pallet racking systems – Principles for structural design) and EN 15635 for operational maintenance and tolerance limits. Material tensile strengths are strictly verified using standard test coupons, and physical deflection conforms to the L/200 criterion under maximum rated UDL.
In accordance with Eurocode 8 (NP EN 1998-1), which governs earthquake-resistant design in Portugal, seismic ground acceleration parameters ($a_g$) vary significantly between the north (Porto) and high-risk zones in the south (Lisbon, Setúbal, and the Algarve).
For projects in high-risk zones, our engineers incorporate oversized baseplates (minimum 8mm thickness), heavy-duty chemical or mechanical expansion anchors (ETA-certified), and back-to-back bracing configurations to withstand lateral and torsional dynamic forces.
For coastal logistics hubs in Aveiro, Leixões, and Setúbal where airborne relative humidity and salt air can degrade standard particle boards, we strongly recommend pre-galvanized ribbed steel decking panels (GI Decking) or zinc-plated welded wire mesh decks.
Wire mesh decks also meet fire safety requirements under the Portuguese National Civil Protection Authority (ANPC), allowing in-rack sprinkler water to penetrate down through multi-tier installations.
Ocean container freight transit time from Jebel Ali Port (servicing our Ajman Free Zone plant) to the Port of Sines, Leixões, or Lisbon averages 22 to 28 days via direct container liner services.
With our rapid 2-3 week production turnaround for standard profiles, typical total procurement lead times are between 5 and 7 weeks from CAD layout approval to delivery at your Portuguese warehouse bay.
Yes. Our heavy-duty upright frames can be engineered continuously up to 8,000mm in height to create multi-tier picking structures (estantes com passadiço). Intermediate walkways utilize structural galvanized steel gratings or non-slip embossed plates supported directly by the racking uprights.
