Technical Specifications:
Material: Aluminum alloy (Alu)
Diameter: 18 mm
Length: 2000 mm (1 meter)
Base type: with thread
Standard: Complies with LST EN 62561-2 (Lightning protection system component standard)
Functions:
Effectively collects lightning discharge and directs it to ground
Lightweight, resistant to environmental effects
Used in various building lightning protection systems
Applications:
Roof lightning protection for residential and industrial buildings
Protection of solar power plants from direct lightning strikes
Protection of engineering structures (towers, antennas, tanks)
Mounting can be done using lightning rod holders, clamps, or connectors suitable for a 18 mm rod. Installation must follow LST EN 62305 and LST EN 62561 standards.
Pros:
Lightweight and durable – made of aluminum alloy, ideal for roof installation
Complies with LST EN 62561-2
Corrosion-resistant – long-lasting even in harsh weather
Cons:
Aluminum is not suitable for direct contact with copper – proper insulation from other metals is required due to potential electrochemical corrosion
A professional grounding system is necessary – improper installation may reduce protection efficiency

Please refer to the technical specification.Active lightning protection – the active lightning rod is raised at the highest point of the building. This system attracts the forming lightning and directs all the current away from other elements of the building. The activity occurs only during a lightning discharge. When choosing an active lightning rod, pay attention to whether the lightning receiver has electronics (can withstand up to 115kA, but may fail if the discharge exceeds the limits) or no electronics (can withstand any strength and number of lightning discharges). Used for the protection of industrial complexes, buildings, residential houses, estates, warehouses, and stadiums.

Passive lightning protection – metal elements installed on the roof (traditional "Franklin" lightning rod). During a lightning strike, the current flows through this metal system into the ground. Typically, galvanized steel wire is used, which is laid along the entire roof length and dropped to the ground. Occasionally, copper wire is used, but due to cost differences, users usually opt for steel, which is cheaper. Around the building, a galvanized steel grounding strip is laid underground.

A lightning rod protects buildings and people from the effects of lightning, but does not protect equipment. Therefore, it is essential to install surge protection.
