Prefab Warehouse Mezzanine Modular Industrial Mezzanine Floor Storage System
Double or triple your usable warehouse space without expanding your building footprint. Gieantech's custom-engineered mezzanine floors create elevated platforms for storage, production, and office use — built with structural steel for decades of heavy-duty performance.
What Is a Planta semisoterrada?
A freestanding elevated steel platform that creates additional usable floor space inside your existing warehouse.
A planta intermedia is a semi-permanent, freestanding elevated platform installed within an existing warehouse or factory building, designed to create additional usable floor space without costly building expansion or relocation. Unlike conventional building floors, industrial mezzanine floors are modular steel structures that can be assembled, reconfigured, or relocated as your business needs evolve.
Gieantech's mezzanine floor systems are engineered with hot-rolled H-section steel columns and primary beams, cold-formed C-section secondary beams, and high-strength steel plank flooring to deliver load capacities from 300 kg/m² to 2,000 kg/m². Whether you need a mezzanine platform for bulk storage, pick-and-pack operations, production lines, or elevated office space, our custom designs maximize your vertical cubic footage and comply with international structural safety standards.

Goods Lift Integration
Hydraulic or mechanical goods lifts (1–5 ton capacity) integrated into the platform for efficient vertical material flow.
Fully Customisable
Custom dimensions, floor finishes (steel plank, grating, plywood), colours, and accessories tailored to your exact requirements.
Planta semisoterrada Configuraciones
Choose from four proven platform architectures — each engineered for specific load, span, and workflow requirements.
Structural Steel Mezzanine
Independent H-beam framework supporting loads up to 2,000 kg/m². Ideal for heavy manufacturing, machinery platforms, and multi-purpose warehouse floors with large open spans.
Mezzanine soportada en bastidores
Uses existing pallet racking as the structural support for elevated floors. Cost-effective solution for e-commerce pick-and-pack, combining storage below with working area above.
Plataforma de múltiples niveles
Three-level mezzanine system with independent staircases and goods lifts. Maximises vertical space for large warehouses with 10m+ clear height.
Cantilever Mezzanine
Extended platform overhanging beyond the column line to cover loading docks, stairwells, or equipment areas. No columns in the overhang zone.
Planta semisoterrada Componentes
H-Steel Columns
Hot-rolled H-section uprights (100×100 to 300×300mm) provide primary vertical load path, anchored with chemical bolts.
Longitudes primarias y secundarias
H-beams and C-channel purlins forming the grid framework. Spans up to 9m between columns without intermediate support.
Steel Plank Flooring
High-strength galvanized steel planks with anti-slip diamond pattern for uniform load distribution and fire resistance.
Staircases & Ladders
Industrial steel staircases with anti-slip treads and handrails in straight, L-shaped, or spiral configurations.
Barandillas de seguridad
1,100mm height guardrails with mid-rail and kick-plate along all open edges compliant with EN ISO 14122.
Goods Lift
Hydraulic or chain-drive goods lifts (1-5 ton capacity) for efficient vertical material transport between levels.
