Warehouse Mezzanine Galvanized Steel Open Platform Plank-Punched Perforated Rack Decking Grating

Open steel plank, widely known as steel grating in global industrial markets, is a high-strength metal panel fabricated through professional punching, rolling, and pressure forming processes. To accommodate different environmental and aesthetic requirements, our steel gratings are available in two mainstream surface finishes: galvanized and powder-coated. Both treatments effectively enhance anti-rust, anti-corrosion and wear resistance, ensuring stable long-term performance in complex indoor and outdoor working conditions.

As a core supporting accessory for industrial racking and steel structure systems, perforated steel grating is extensively applied for mezzanine flooring, steel platform walkways, equipment operation platforms, and rack shelving decks. Thanks to its standardized perforated open structure, the panel features excellent ventilation, heat dissipation and drainage capacity. Most importantly, the hollow open design fully complies with international fire safety regulations, making it a qualified fire-resistant flooring solution for factory warehouses, logistics centers and industrial buildings.

Our precision-engineered steel grating panels adopt a reinforced two-layer closed-edge structure, delivering outstanding structural stability, load-bearing capacity and anti-slip performance. The uniformly punched slots ensure consistent force distribution, effective water drainage and clean self-ventilation, while the solid closed-edge design prevents deformation and sharp edges. Easy to cut, assemble and install, these steel gratings perfectly match all standard industrial racking systems and multi-level mezzanine structures. With reliable durability and low maintenance requirements, they serve as a cost-effective, long-lasting solution for industrial storage and platform construction projects worldwide.

Loading capacity for Mezzanine Galvanized Steel Plank

The floor can be designed into the open plank or grating plate, to meet the requirement for lighting and fire fighting, compared to corrugated steel plates or grates with lath and lentil form.

The rack mezzanine is suitable to store a large variety of goods

Key Benefits of Perforated Steel Grating Panels

High Load Performance

Reinforced perforated design supports heavy-duty industrial loads without deformation.

Excellent Corrosion Resistance

Available in both galvanized and powder-coated finishes for long-term durability in harsh warehouse environments.

Safe and Anti-Slip Surface

The punched slots increase grip for personnel and equipment, enhancing operational safety.

Quick Integration

Designed for easy installation into new or existing mezzanine floor systems.

Custom Options

We offer tailored solutions in size, thickness, and surface finish to meet your specific project requirements.

Mezzanine floor brief introduction

Mezzanines add a second d or third level inside your facility to create more usable space. These mezzanines are customized to fit your exact area, height, and color and load requirements. The bottom shelves support the upper platform. Taking full advantage of the space, it is a typical application for manual picking goods.

Slides or ramps can be optionally customized for the multi-layer rack system. For high management efficiency, platform lorry is selective to be used in the two-layer racks if required.

Mezzanine floor features

The rack mezzanine is extensively used in the condition of high warehouse, small goods, and manual access. It can make full use of the space and save the area of the warehouse.

The rack mezzanine is safe and easy to install due to the scientific design.
