Understanding Mesh Conductor Systems

Mesh conductor systems consist of a network of conductors that form a grid-like pattern over the roof of a structure. This mesh works collectively to intercept lightning strikes, providing a controlled path for the electrical discharge to reach the ground safely.

Design and Configuration

The design of mesh conductor systems is tailored to the specific geometry of the building’s roof, ensuring comprehensive coverage and protection. The mesh size and configuration can vary depending on the structure's size, height, and environmental exposure.

Advantages of Mesh Conductor Systems

Mesh systems offer several benefits over traditional lightning protection methods, particularly for structures with complex architectural designs.

Enhanced Coverage and Protection

The grid-like design of mesh systems provides extensive and uniform coverage, ensuring that lightning strikes are effectively intercepted and dissipated, regardless of the strike point on the roof.
