Product Introduction
The aluminum I bar grating is engineered for projects requiring high mechanical performance with reduced self-weight. This aluminum I bar grating uses an I-shaped bearing bar profile, which significantly lowers material usage while maintaining structural rigidity under spans up to 1200 mm (for L/200 deflection). From an economic perspective, the press-locked connection (no welding) reduces fabrication labor, and the lightweight nature (~2.7 g/cm³) cuts shipping and handling costs. Additionally, the mill or anodized finish provides long-term durability with minimal maintenance, and the removable clip fixing system allows for panel reuse, improving lifecycle value without compromising safety (slip resistance R10-R12).

Product Advantages
1. I-bar profile reduces aluminum consumption per square meter compared to rectangular bars, lowering material cost.
2. Press-locked connection eliminates welding labor and associated quality inspection expenses.
3. Lightweight (~2.7 g/cm³) reduces shipping freight and allows installation by fewer workers without lifting equipment.
4. Clip fixing system enables quick removal and relocation, preserving panel value for future projects.
5. Serrated surface (R10-R12) provides anti-slip property without adding extra anti-slip treads or coatings.
Application Scenarios
Walkways
Use 30×3 mm bearing bars at 30 mm spacing for safe, anti-slip pedestrian passage.
Platforms
Use 40×4 mm bearing bars at 30–40 mm spacing for light industrial maintenance platforms.
Rooftop Access
Use 25×3 mm bearing bars at 30 mm spacing for lightweight, corrosion-resistant rooftop walking surfaces.
FAQ
Q1: Can L-shaped aluminum I bar grating be used on a mezzanine where forklifts occasionally pass?
No, it is not recommended for any heavy vehicle traffic or forklift lanes. For example, a 40×5 mm grating with 30 mm spacing may still deflect permanently under a 2-ton forklift due to aluminum's lower yield strength (~110 MPa) compared to steel. Please use steel grating for forklift applications.
Q2: How do I fix the grating panels to avoid drilling holes on site?
Use aluminum or stainless steel clips (2–4 clips per panel). For instance, on a 1000×3000 mm rooftop walkway, four clips per panel allow tool-free removal for roof membrane maintenance, while bolted fixing would require unscrewing each bolt. Clips also accommodate thermal expansion without warping the panel.
