Key Advantages

1. Superior Corrosion Resistance
   The hot-dip galvanized coating (average thickness ≥80μm) ensures 20+ years of service life in humid and corrosive environments, significantly reducing maintenance costs for industrial steel grating.

2. Excellent Load-Bearing Capacity
   The 30mm equally spaced bearing bars and 3mm cross bars create a stable grid structure with uniform load capacity up to 3.0kN/m², meeting requirements for heavy-duty steel grating.

3. Integrated Safety Design
   Optional serrated surface pattern combined with over 40% open area ensures anti-slip safety while enabling rapid drainage, making it ideal for drainage grating applications.
