What type of fasteners should be avoided in lightning protection installations?

In lightning protection installations, galvanized steel fasteners should be avoided due to their susceptibility to corrosion when exposed to the elements and the high conductivity required for effective lightning systems. Corrosion can diminish the integrity and reliability of the connection, potentially compromising the effectiveness of the lightning protection system over time.

Stainless steel, brass, and copper, on the other hand, are favored materials in these applications. Stainless steel is well known for its strength and resistance to corrosion, making it a suitable choice for long-lasting and reliable installations. Brass offers good conductivity and is also resistant to corrosion, which allows it to maintain its performance in various environmental conditions. Copper is highly conductive, making it essential in lightning systems, as it provides an efficient pathway for lightning surges.

Therefore, selecting fasteners that will not corrode and maintain high conductivity is essential to the safety and functionality of lightning protection systems, highlighting why galvanized steel is an unsuitable option.
