China Mezzanine Racking Solutions | Steel Platform Shelving Suppliers & Factory for Efficient Warehouse Space Utilization
System Composition and Classification
Supported by rack uprights/independent steel frames, combined with beams and specialized floor panels (patterned steel plates, steel grating, plywood); standard configuration includes stairs, guardrails, and lifting platforms/freight elevators; modular assembly, no on-site welding required.
| Type | Load Capacity per Floor | Applicable Goods | Typical Floor Slab |
|---|---|---|---|
| Medium Mezzanine | 300–500 kg/m² | Cardboard boxes, parts boxes, small e-commerce parcels | Steel grating / Composite panels |
| Heavyweight Mezzanine | 500–1000+ kg/m² | Small pallets, industrial parts | Patterned steel plate / Welded steel platform |
Standard 2 floors, some 3 floors; total height is limited by warehouse clearance, fire safety, and operating height (generally 2.2–2.8m clear height per floor).
Work Flow and Mode
Inbound
Whole batches of goods are delivered to the mezzanine entrance by forklifts/lift platforms; manual transport is done by handcarts/hydraulic pallet trucks to the upper storage locations; full pallets can be placed on the bottom floor, and individual items can be sorted on the upper floor.
Outbound
Picking is done according to orders at the corresponding zones, and goods are transported to the ground for verification and packaging via stairs/lift platforms.
Core Model
Layered and zoned management, enabling integrated warehousing and office space (office on the upper level, storage on the lower level); does not rely on large-scale automated equipment, but is manually managed and flexibly adjustable.
Core Advantages and Limitations
- ✓ Vertical space utilization increased by 50%–80%, no need to expand factory buildings, cost far lower than adding new warehouses.
- ✓ Modular design, easy to assemble and disassemble, relocatable and reusable; customizable zoning and load-bearing capacity.
- ✓ Lower investment cost than shuttle/automated storage systems, simple maintenance, low energy consumption.
- ✓ Suitable for multiple categories and small to medium-sized items, intuitive sorting and inventory.
- ✗ Upper-level operations rely on manual labor, unsuitable for ultra-high throughput and rapid turnover of heavy pallets.
- ✗ Economic efficiency significantly decreases when warehouse ceiling height is below 5m (recommended ≥6m).
- ✗ High fire safety requirements (requires separate permitting, smoke detectors, sprinklers, and evacuation routes).
- ✗ Vertical transport efficiency is lower than aisle stacker cranes.
Applicable Scenarios and Selection Considerations
E-commerce sorting, electronic components, hardware accessories, clothing, printing, auto parts, food and daily chemicals.
Especially suitable for scenarios with limited warehouse space, ample ceiling height, and primarily manual picking.
