Wedge Wire Floor Grates – Durable, Non-Clogging Drainage Solutions

Wedge wire floor grate is a type of drainage cover made from wedge-shaped wires that are welded together at each intersection. This design creates a durable and high-strength grate that is suitable for floor drainage applications. The wedge-shaped wires are arranged to form a series of slots, which allow water and fine particles to pass through while blocking larger debris.
