A grate drain is a type of drain that uses a grate (a grid-like cover) to allow water to flow into a drainage system while preventing larger debris from entering and clogging the pipes. They are crucial for managing surface water runoff, preventing flooding, and protecting drainage systems from debris.
Production Line Capabilities |
1.Vacuum Casting Line: Enables large-batch production and smooth surface medium parts

2.Resin Sand Casting Line: Delivers big complex geometries, but small quantity

3.Clay Sand Casting Line: Enables large-batch production small part and smooth surface medium parts

4.Medium-frequency Induction Furnace: Make sure uniform melting and stable quality
