  Are lightning rods effective for all types of buildings or structures?

  Introduction to Lightning Rods Lightning rods are devices designed to protect structures from lightning strikes by providing a safe pathway for the electrical discharge to travel to the ground. These rods are typically made of conductive materials, such as copper or aluminum, and are installed at the highest points of a building or structure. The purpose of a lightning rod is to redirect the electric charge from a lightning strike, preventing damage to the structure and reducing the risk of fire...

  Exothermic Welding for Earthing: Principles, Advantages and Supply Options

  Exothermic welding, sometimes referred to as thermite welding or exothermic bonding, is a proven method for permanently joining conductors for earthing (grounding). This process is particularly effective for connecting dissimilar metals. It works without an external heat source, using a chemical reaction from a thermite-based weld powder to generate intense heat. This heat melts the conductors, creating a robust, low-resistance bond as the materials cool and solidify. Exothermic welds offer a su...
