As telecommunication networks expand across Catalonia—driven by 5G densification, smart city initiatives in Barcelona’s 22@ Innovation District, and critical infrastructure modernizations—the demand for reliable, thermal-efficient outdoor equipment enclosures has never been higher. Nexa Prefab manufactures elite-grade OEM/ODM modular telecom shelters engineered specifically to withstand coastal salt-fog corrosion, intense solar loading, and heavy urban or remote deployment challenges.
Explore our factory-engineered prefabricated shelters, customizable under complete OEM/ODM agreements for telecommunication operators, tower companies (TowerCos), and system integrators serving Barcelona and broader Europe.
5G Base Station
Rugged steel-framed base station equipment room designed for heavy radio gear, battery banks, and dual-redundant HVAC units.
Multi-Bay Modular
Multi-room modular shelter allowing clear spatial segregation between power rectifiers, battery storage, and operator electronics.
Edge Compute
Compact micro-data center shelter optimized for low-latency urban 5G edge node processing in smart city environments.
Fiber Distribution
Pre-wired optical distribution cabin featuring automated cable management, security access control, and fire suppression systems.
Rapid Deployment
Lightweight yet ultra-durable steel container shelter designed for rapid helicopter or crane installation in remote mountain sites.
Power Systems
Specialized thermal-insulated shelter for lithium-ion battery banks, featuring explosion-venting doors and climate control.
Coastal Marine
Marine-grade galvanized shelter engineered with C5-M anti-corrosion protection specifically for Mediterranean port and shoreline deployments.
Green Hybrid Solar
Eco-friendly telecom equipment shelter equipped with rooftop photovoltaic mounts and smart inverter integration for zero-grid locations.
Building critical infrastructure along the Western Mediterranean coastline presents a unique combination of environmental and regulatory demands. Telecommunications civil work teams in Barcelona face rigorous municipal urban regulations, strict EU environmental directives, and demanding atmospheric conditions ranging from saline maritime humidity to intense summer solar heat gain.
Barcelona’s coastal topography—extending from the Port of Barcelona through Barceloneta to Badalona—exposes outdoor infrastructure to aggressive airborne chlorides. Standard steel structures degrade rapidly under these conditions without specialized surface treatment.
Nexa Prefab’s OEM modular telecom shelters utilize cold-formed high-tensile structural steel (S350GD + Z275/Z600 hot-dip galvanization) coated with an epoxy-primer and polyurethane topcoat system. This process is certified to meet ISO 12944 C5-M (Very High Marine Corrosion) environmental classification. Laboratory salt spray testing validates over 1,500 hours of continuous exposure with zero degradation, ensuring a 30+ year design life in coastal environments.
Engineered according to Eurocode 3 (EN 1993) to resist seismic activity (EN 1998) and Mediterranean wind forces reaching 160 km/h (EN 1991-1-4).
High-density Polyisocyanurate (PIR) core sandwich panels provide thermal conductivity as low as 0.022 W/mK, significantly lowering HVAC energy loads.
Multi-point anti-vandal door locks, hidden hinges, internal cable glands, and optional RC3/RC4 security classification guard against intrusion.
In hot Mediterranean summers, solar radiation on shelter roofs can push internal ambient temperatures far beyond acceptable thresholds for sensitive BBU (Baseband Units), rectifiers, and optical switching equipment. Maintaining a constant internal temperature of 20°C to 25°C while minimizing power consumption requires precise engineering:
| Parameter | Standard Specification | OEM Custom Options |
|---|---|---|
| Structural Frame | Hot-dip galvanized profile steel (2.75mm - 4.0mm) | Heavy-duty crane-liftable corner castings; flat-pack knock-down frames |
| Wall & Roof Cladding | 80mm PIR core sandwich panel (Density: 40 kg/m³) | Rockwool (Mineral Wool) EI120 fireproof panels; PU foam insulation |
| Anti-Corrosion Rating | ISO 12944 C3/C4 Coating (160µm total thickness) | ISO 12944 C5-M Marine Coating (240µm+ hot-dip + PU finish) |
| Egress Protection | IP65 (Dust tight & water jet resistant) | IP66 with pressurized dual-gasket sealing systems |
| Fire Rating | B-s1, d0 (EN 13501-1) flame retardant | EI60 / EI90 / EI120 complete structural fire rating options |
| Cooling System | Inverter dual-redundant wall-mounted AC units | Direct free-cooling dampers; heat exchangers; DC emergency ventilation |
Nexa Prefab telecom shelters are built to support diverse topographical and structural deployment demands across the Metropolitan Area of Barcelona (AMB) and surrounding provinces.
In Barcelona’s technology district, spatial constraints require ultra-compact, aesthetic edge computing shelters. Our sleek modular units fit onto existing concrete pads or building rooftops with zero structural intrusion.
Mountaintop broadcast and repeater sites surrounding Barcelona demand wind-resistant, high-insulation shelters designed for rapid crane assembly on steep terrain with minimal environmental footprint.
Handling maritime telecommunications and private 5G port networks. Our C5-M coated shelters protect sensitive fiber nodes against continuous salt-air exposure and severe heavy-industrial pollutants.
Customized fire-rated equipment shelters positioned along the AVE rail corridors and transport tunnels, featuring automated fire extinguishing systems and vibration isolation dampers.
Deployed across interior Catalonia to house SCADA systems, remote solar storage, and IoT gateways for regional water authorities and renewable energy farms.
Lightweight structural steel shelters designed specifically for roof load limits on historic and modern commercial buildings in Eixample and Les Corts.
