Should a metal gazebo be grounded?

A metal gazebo should be grounded if you want to keep it safe from lightning strikes. You can ground it by mounting copper rods to the base of the gazebo. Drive the rods into the ground, ensuring that they're at least six inches deep. This placement will keep your gazebo safe from lightning.

Why do I need grounding?

Grounding your electrical systems is critical to protect both building occupants and equipment from the danger of high voltage. When a conductive surface, like metal, is not grounded and becomes electrically energized, it can carry sufficient voltage to administer a fatal shock.

What metal is used in a metal roof?
