Steel Grating Cover for Garage Drain Pit

Grate covers for drainage pits are steel structures designed to cover drainage pits, combining drainage, anti-slip, and load-bearing functions. They are widely used in municipal, industrial, and civil applications.

Structure and Materials

The grates are formed by cross-welding load-bearing flat bars and crossbars. The surface is typically hot-dip galvanized, offering excellent corrosion resistance and a service life exceeding 30 years. Materials are categorized into stainless steel and carbon steel based on environmental requirements. Carbon steel undergoes hot-dip galvanization to significantly enhance corrosion resistance.

Core Advantages

Drainage Performance: Open grid structure (typical flat bar spacing 25-60mm) ensures rapid water flow and prevents pooling.

Load-Bearing Capacity: Standard crossbar spacing of 50/100mm supports pedestrian traffic and small equipment passage.

Anti-Slip Properties: Surface design enhances friction, boosting safety by 3-5 times in wet conditions;

Cost-Effectiveness: Lower initial investment than concrete materials, minimal maintenance costs, and significant lifecycle cost advantages.

Application Scenarios

Municipal Infrastructure: Urban roadways, park green space drainage systems;

Industrial Settings: Covering factory sump pits to maintain dry workshop floors;

Transportation Sector: Parking lots, highway drainage systems.
