Steel structures for industrial warehouses
We design, fabricate and install the steel structure of industrial warehouses across Spain. We work for developers, contractors, logistics operators and end industry, on projects ranging from a small 200 m² unit to logistics complexes spanning several hectares. Each structure is calculated to spec based on span, height, loads, location and roof type, with certified steel and qualified welding.
What a steel structure for an industrial warehouse includes
A steel structure for an industrial warehouse comprises columns and frames that transfer vertical loads (self-weight, live loads, snow, suspended equipment) and horizontal loads (wind, seismic) down to the foundations. Purlins rest on the frames to receive the roofing, and side cladding fits between columns. When clear span is critical, central frames are replaced with trusses to span up to 30 or 40 metres without intermediate columns.
The standard steel-structure scope normally covers: engineering and fabrication drawings, steel supply and machining, shop welding, special transport when geometry requires it, on-site installation with crane, in-situ bolted connections, finish paint and CE marking certificate. Foundations, services and interior finishes are separate items coordinated with the other trades.
- HEB columns or welded box sections for heavy loads
- Solid-web or trussed frames depending on span
- Cold-formed roof purlins (CF, ZF profiles)
- Roof and side bracing
- Base plates and anchor bolts sized to load
- Shop-welded and site-bolted connections
Types of warehouses we build
Not every industrial warehouse is engineered the same way. Depending on intended use, required clear height, process equipment and preferred bay spacing, the structural solution changes. These are the typologies we deliver most often:
- Long-span logistics warehouses for 3PL operators and distribution centres
- Industrial warehouses for manufacturing, workshops and serial production
- Food-industry warehouses with cold rooms and refrigerated docks
- High-bay storage warehouses (silos, racking up to 12 m)
- Auxiliary warehouses for hospitality, retail and events
- Multipurpose warehouses with administrative loft or technical mezzanine
- Warehouses for vehicle inspections, car washes and mobility services
- Warehouses for farms, equine centres and rural agribusiness

Structural design, fabrication and installation
Each project starts with a feasibility outline defining overall geometry (span, height, number of bays), governing loads and the most efficient column spacing. Our in-house engineering then produces the structural calculation in line with CTE-DB-SE-A, EAE and where applicable Eurocode 3, together with detailed fabrication drawings.
Fabrication takes place entirely in our own workshop: CNC sawing and oxy-cutting, drilling, assembly, welding qualified to UNE-EN ISO 9606 and shop primer or galvanizing. Each part is identified and accompanied by dimensional control. Transport is planned to optimise loads and, for oversized pieces, special permits and vehicles are arranged.
On site, installation is carried out with mobile crane and aerial platforms following a strict sequence: setting out, column erection, frame assembly, purlin and bracing placement and final adjustments. We work in coordination with the project manager and hand over as-built drawings, welding certificates and structural CE marking.
Materials, profiles and standard solutions
The base material is hot-rolled structural steel, S275JR (general use) or S355JR (heavy loads or singular pieces). Cold-formed CF and ZF profiles are used for purlins, with tubular sections for bracing. For aggressive environments — coast, chemical or refrigerated — we use hot-dip galvanizing or multi-coat paint systems (epoxy + polyurethane).
For roofing, the most common solutions are sandwich panel (fast installation, good insulation), corrugated steel sheet with on-site insulation (more economical, requires periodic maintenance) and deck systems (high thermal and acoustic performance). Side cladding is resolved with sandwich panel, mini-rib steel sheet, precast concrete panels or combinations to suit the desired look.
- S275JR / S355JR steel as required by calculation
- Hot-rolled IPE, HEB, HEA and UPN profiles
- Square and rectangular structural tubing
- PIR/PUR sandwich panel roofing 30, 40, 50, 60 or 80 mm
- Deck roofing with mineral wool blanket and waterproof membrane
- Vertical or horizontal sandwich panel cladding
- Hot-dip galvanizing for corrosive environments
Advantages of building a warehouse with steel
Compared with reinforced concrete or hybrid solutions, steel structure delivers shorter site times because most of the work happens in the workshop while foundations are being poured. Bay spacing is flexible and future extensions slot in without demolition. Steel is recyclable and allows tight design: less material weight for the same load capacity.
Another major advantage is large-span performance: with trusses or solid-web beams you cover 25, 30 or 40 metres without intermediate columns, multiplying logistics and operational productivity. And in case of a change of use or added suspended equipment (overhead cranes, services), the steel structure accepts targeted reinforcements without major works.
Who we work for
We work with three clearly distinct client profiles, each with different expectations:
- Developers and main contractors who need a reliable steelwork firm that hits deadlines and hands over complete documentation.
- End industry expanding their facilities, replacing an old roof or building a second warehouse.
- Logistics operators requiring warehouses with loading docks, technical mezzanines and provisions for future extensions.
- Architecture and engineering firms outsourcing the design, fabrication and installation of the steelwork.
