Key Features of Steel Grating Gully Cover and Well Cover
Feature 1: Optimal Drainage Efficiency
Water leakage area reaches 83.3%, more than double that of traditional cast iron covers. This means faster water flow and reduced flood risk during tropical storms.
Feature 2: Anti-Theft Design
Covers can be connected to frames with hinges or gemel connections, ensuring theft protection while allowing convenient opening for maintenance access.
Feature 3: Superior Strength vs. Cast Iron
Steel grating offers strength and toughness far exceeding cast iron, making it suitable for large-span and heavy-load environments like wharves and airports.
Feature 4: Cost Savings
With larger span capabilities and reduced weight, total installed cost is lower than cast iron under heavy load conditions. Replacement expenses due to theft or crushing are also minimized.
