A warehouse steel platform creates usable floor space above ground level without expanding the building footprint. Our steel mezzanine system uses cold-rolled Q235B or Q345B structural steel with bolt-together connections — no field welding required. Standard configurations support 2–3 levels with clear heights of 2.2m–3m per floor. The industrial storage platform is engineered to FEM 10.2.02 and FEM 10.2.09, with load ratings from 500kg/m² for light assembly to 2000kg/m² for heavy pallet storage. Each project starts with a site survey and CAD layout so the multi-level warehouse structure fits around existing equipment and fire exits.
Key Features
- Structural steel Q235B / Q345B, yield strength ≥235MPa (Q235B) or ≥345MPa (Q345B)
- Standard load 1000kg/m², engineered up to 2000kg/m² for palletized goods
- Modular bolt-together frame — no field welding, faster installation and reconfiguration
- 2–3 level configurations, clear height 2.2m–3.0m per floor, adjustable column spacing
- Three decking options: steel grating, chequered plate, or plywood
- Integrated safety: toe boards, guardrails (1100mm), self-closing safety gates, stair access
- Powder coating (60–80μm) or hot-dip galvanizing (80μm avg.) for corrosive environments

Decking Options
| Steel Grating Open-bar grating (serrated or plain) for ventilation, drainage, and fire-sprinkler compliance. Commonly used in food processing, chemical storage, and areas requiring airflow beneath the platform. |
| Chequered Plate Hot-rolled chequered steel plate (2–3mm thickness) with raised diamond pattern for anti-slip footing. Suitable for high-traffic walkways, picking stations, and forklift-accessible mezzanine floors. |
| Plywood (Moisture-Resistant) 18–22mm structural plywood over steel beam grid. Cost-effective option for office space, clean rooms, or light-duty storage where a smooth, finished surface is required. |
Applications
- Elevated Warehouse Storage — Convert unused vertical space into a second-level storage deck. A typical 500m² warehouse gains 300–500m² of additional storage with a 2-level steel platform.
- Production Mezzanine — House assembly lines, packing stations, or quality inspection areas above ground floor operations.
- Equipment Platform — Support HVAC units, conveyors, or machinery at elevated height with point-load calculations for specific equipment weight.
- Office Overbuild — Create enclosed office space or break rooms above the warehouse floor without additional construction permits in most jurisdictions.

Frequently Asked Questions
What is the load capacity of a steel mezzanine platform?
Standard capacity is 1000kg/m² for carton storage and light assembly. For pallet storage or heavy machinery, we engineer up to 2000kg/m² using larger beam sections and closer column spacing. The exact rating is determined during design based on your intended use.
How is a steel platform installed — does it require welding?
No field welding. All connections use high-strength bolts. The frame arrives pre-cut and pre-punched from our factory. A typical 200m² platform takes 5–7 days for a crew of 4–6 with basic tools.
What decking type should I choose for my application?
Steel grating is standard — it allows light, air, and sprinkler water through. Chequered plate suits forklift access or heavy foot traffic with anti-slip surface. Plywood is the economical choice for office overbuilds where a smooth finish is preferred.
Can a steel mezzanine system be relocated or expanded?
Yes. Bolted connections allow disassembly and reassembly at a new location. Additional bays can be added later if the original design included expansion capacity. We recommend discussing future expansion plans during initial design consultation.
Do you provide engineering drawings and load calculations?
Every order includes general arrangement drawings, connection details, FEM 10.2.02 load calculations, bill of materials, installation manual, material test certificates, and CE conformity declarations.
