Steel Grating for Industrial Flooring
Bar grating is the industry standard for mezzanine floors, process plant platforms, and factory maintenance walkways. Open surface provides natural drainage and ventilation while meeting structural load requirements.

Why Steel Grating for Industrial Floors?
- Natural drainage — spilled liquids drain through without pooling, reducing slip hazard
- Ventilation — open surface allows hot air, fumes, and dust to pass through; critical in furnace areas and chemical plants
- Weight savings — 30–50% lighter than steel plate flooring, reducing structural steel cost
- Visibility — maintenance staff can see equipment and services below the floor level
- Speed of installation — pre-fabricated panels drop into support framing; no welding required
Typical Specification by Industry
| Industry | Typical Spec | Surface Finish |
|---|---|---|
| General factory / warehouse | 25×5mm @ 30mm, plain | Black or galvanized |
| Process chemical plant | 25×5mm @ 30mm, serrated | Galvanized or SS 316 |
| Food processing | 25×5mm @ 30mm, serrated | SS 304 or SS 316 |
| Steel / metals plant | 40×5mm @ 22mm, serrated | Plain black |
| Power station | 40×5mm @ 30mm, plain | Galvanized |
| Offshore platform | 25×5mm @ 30mm, serrated | Hot-dip galvanized |
Span & Load Class Reference
Select bearing bar depth based on the clear span (support to support) and design load. General guideline:
- Span ≤ 600mm: 25mm bearing bars adequate for most industrial loads
- Span 600–1000mm: 30–40mm bars for typical 5 kPa design load
- Span 1000–1500mm: 40–50mm bars; verify with load calculator
- Span > 1500mm: 50–65mm bars; consult structural engineer
FAQs
What load capacity is required for industrial flooring?
Most industrial facilities require floors rated for 5–15 kPa UDL (100–300 psf) depending on the application. Forklift traffic may impose 20–50 kN wheel loads. Use the load capacity calculator with your specific span and bearing bar to verify.
What bearing bar specification is most common for industrial floors?
25×5mm @ 30mm pitch is the most common spec for general industrial use. Heavier spans or vehicle traffic may require 40×5mm or 50×5mm @ 22mm pitch.
Does industrial grating flooring meet fire rating requirements?
Steel bar grating is a non-combustible material. However, grating flooring does not typically provide a fire-rated floor assembly on its own. For fire-rated applications, a solid infill or fire-rated decking system is normally required.
