Aluminum Bar Grating
Lightweight, naturally corrosion-resistant bar grating in 6061-T6 or 6063-T5 aluminium. Approximately 34% lighter than equivalent steel grating — ideal for weight-sensitive structures.

Select Aluminum (2.70 g/cm³) in the material dropdown — results show ~34% of carbon steel weight.
Key Properties
When to Specify Aluminum vs Steel
| Consider Aluminum When… | Stick with Steel When… |
|---|---|
| Weight is critical (mezzanines, roof access) | Heavy loads / long spans required |
| No painting or galvanizing budget | Cost is primary driver (steel ~30–50% cheaper) |
| Marine or coastal environment | High-impact resistance needed |
| Chemical splash, acids (except strong alkalis) | Welding to structural steel frame |
| Aesthetic / architectural applications | High-temperature service (>150°C) |
Common Applications
- Mezzanine flooring (reduced structural load)
- Marine vessel decking
- Architectural walkways and bridges
- Airport and transit facilities
- Roof access platforms
- Swimming pool surrounds
- Food processing (secondary areas)
- Clean room access floors
Sourcing Notes
Anping factories produce aluminum grating by press-locking or welding aluminum extrusions. Sizes and pitches match the carbon steel product line. MOQ typically 2–5 tonnes; lead time 25–35 days.
Anodizing (clear or coloured) available at an additional cost. Specify alloy grade and surface requirement in your inquiry.
Frequently Asked Questions
What alloy is used for aluminum bar grating?
The most common alloys are 6061-T6 (North America) and 6063-T5/T6 (export from China). Both are structural alloys with good corrosion resistance and weldability. 6061-T6 has higher strength; 6063-T5 offers better extrudability for complex profiles.
How does aluminum grating weight compare to steel?
Aluminum grating weighs approximately 34% of equivalent carbon steel grating (density 2.70 vs 7.85 g/cm³). A standard 25×5mm @ 30mm pitch spec weighs about 12.8 kg/m² in aluminum vs 37.1 kg/m² in steel.
Does aluminum grating need corrosion protection?
Aluminum naturally forms a thin oxide layer that provides excellent atmospheric corrosion resistance. No coating is required in most environments. Anodizing adds extra protection and can provide colour. Avoid direct contact with carbon steel or concrete (galvanic/alkali attack).
Is aluminum grating safe in explosive atmospheres?
Aluminum alloys can produce sparks in certain impact conditions. For ATEX-rated explosive atmospheres (petrochemical, dust), consult your explosion protection engineer. Stainless steel or fibreglass grating is typically preferred for classified zones.
