Mezzanine Shelving

This is a multi-level storage facility that expands space by building 2-3 mezzanine levels within the warehouse. Each level has a load-bearing capacity of ≤500kg/㎡ and requires stairs or elevators for transferring goods between floors. It is suitable for warehouses with a ceiling height of ≥4 meters. It makes full use of vertical space and is a typical application of height utilization in manual picking racks.

Function

It enables tiered and categorized storage of small and medium-sized items and loose goods. The upper layer can store large quantities of stock, while the lower layer is used for frequently picked goods, balancing storage capacity and ease of access.

Advantages

Significantly improves warehouse vertical space utilization, doubling storage capacity;

Flexible layout, allowing for zoned storage by product type;

Relatively simple construction, with potential for adjustment or expansion later;

The floor is covered with specialized shelving flooring, offering advantages over patterned steel plates or steel grating, including stronger load-bearing capacity, better overall integrity, more uniform load distribution, a smoother surface, and easier locking.

Structure

Support System (Load-Bearing Core)

Columns: Overall load-bearing frame
Main Beams: Main beams supporting the floor slab
Secondary Beams/Support Beams: Auxiliary support for the floor slab, distributing local loads
Column Braces/Diagonal Braces: Enhance column stability, resist horizontal forces. Angle steel/round steel, welded or bolted to the columns. Arranged crosswise according to mechanical principles to improve overall anti-overturning capacity.

Floor System (Cargo Load-Bearing Layer)

Floor Type | Structural Characteristics | Applicable Scenarios | Load-Bearing Capacity
Patterned Steel Plate | Good anti-slip performance, strong overall integrity
Interlocking Cold-Rolled Steel Floor Slab | Assembled type, six-dimensional locking mechanism, high precision
Wood/Plywood | Low cost, easy to install. Light cargo (stationery, small parts)
Steel-Clad Plate | Steel plate + insulation/fireproof layer composite, versatile functions

Auxiliary Safety Facilities (Essential)

Staircase: Steel structure
Guardrails arranged along the floor edge to prevent people/cargo from falling
Lifting Equipment Interface: Reserved for freight elevator/ Hydraulic lifting platform location, improving the efficiency of moving large goods up and down stairs, load capacity 500-2000kg
Fire protection facilities: Smoke detector/sprinkler system interface, passage width ≥1.2m, meeting fire protection regulations
Lighting/Power supply: Reserved cable trays to ensure illuminance ≥100lux in the upper working area

Connection and fixing system

Assembled structure, bolted connection, no on-site welding required, easy installation, and can be disassembled and reassembled.
Columns to the ground: Fixed with expansion bolts, embedding depth ≥100mm, ensuring pull-out/shear strength.
Floor slabs to beams: Fixed with special clips/bolts to prevent slippage and ensure the integrity of the floor.

Application Industries And Scope

Due to its simple structure, strong versatility, easy assembly, and low implementation cost, warehouse pallet shelves are the most commonly used storage system. They are particularly suitable for the following situations:

Manufacturing (Spare Parts/Materials/Semi-finished Products Warehouse, Workshop Support Warehouse)

Manufacturing is a core application area for mezzanine racking, especially suitable for warehousing needs involving small to medium-sized items, multiple product categories, and low turnover.

E-commerce & Third-Party Logistics (3PL) (Small to Medium-Sized Items/Small Item/Package Warehouse, Warehouse Management)

Suitable for e-commerce/logistics scenarios with many SKUs, small to medium-sized items, primarily sold in smaller quantities, and requiring zoning. Not suitable for bulk warehouses with high-frequency, full-pallet turnover.

Retail Chains (Store Stock Warehouse, Regional Distribution Center Small Item Area)

Suitable for retail distribution scenarios with many stores, many small items, and multiple product categories zoning.

Pharmaceuticals & Chemicals (Compliant Small to Medium-Sized Item Warehouse, Batch Number/Expiration Date Zoning)

Suitable for compliant warehousing scenarios involving small to medium-sized items, multiple batch numbers, and requiring zoning and isolation.

FAQs

Are there any fire resistance requirements for mezzanine shelving? What fire-fighting equipment is required?

The warehouse must comply with fire safety regulations. The shelving must be made of steel (non-combustible material) and meet fire resistance standards. The upper area must be equipped with independent smoke detectors and portable fire extinguishers (one set per 50 square meters). If the upper area exceeds 100 square meters, a sprinkler system must be installed. Emergency lighting and evacuation signs must be installed at stairwells.

What are the upper levels of mezzanine shelving suitable for? Can it be used in an office?

The upper space is mainly used for storing goods, especially suitable for goods with large-volume stocking and low turnover frequency (such as seasonal inventory and spare parts); some areas can also be planned as office areas according to needs, but two conditions must be met: first, the load-bearing capacity of the office area must be ≥200kg/㎡; second, sound insulation and ventilation must be done well, and the office area must be separated from the storage area by a guardrail.

Are there any requirements regarding the original structure of the warehouse for mezzanine racking? Can it be installed in a rented warehouse?

The requirements for the original warehouse structure are low, requiring no load-bearing walls for support. The shelving itself is fixed to the ground by uprights, offering strong independence. It can be installed in leased warehouses. Due to its modular structure, it can be disassembled and reassembled during relocation without damaging the original warehouse floor and walls. It is only necessary to confirm with the landlord in advance whether the floor's load-bearing capacity meets the standards.

What are the options for stairs and cargo transfer equipment for mezzanine racking?

Staircases can be either fixed steel ladders (width ≥ 800mm, slope 30-45°) or lifting platforms; cargo transfer equipment can be selected according to needs: electric lifting platforms for cargo (50-200kg), small cargo elevators (load ≤ 1000kg) for bulk cargo, and some can be equipped with conveyor belts to achieve automated transfer.

What is the maximum number of layers that can be built in a mezzanine shelving unit? What is the load-bearing capacity of each layer?

Standard setups typically have 2-3 layers, with a maximum of 3 layers (due to height limitations and load-bearing safety). Each layer has a standard load-bearing capacity of 200-500 kg/m². For higher load-bearing capacities (e.g., 500-800 kg/m²), additional materials (thickened uprights, main beams, secondary beams, floor slabs, etc.) are required, necessitating professional custom design from the manufacturer.
