Understanding Metal Roofing

Leading manufacturers typically offer a range of galvanizing processes, such as hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing involves immersing the metal in molten zinc, resulting in a thicker coating that provides superior corrosion resistance. On the other hand, electro-galvanizing applies a thin layer of zinc through an electrochemical process, often resulting in a more polished finish, but may not offer the same level of protection as hot-dip galvanization.

Grounding screws are small metal screws specifically designed to provide a secure connection point for grounding wires within metal electrical boxes. These screws offer a reliable connection between the grounding conductor and the metal box, ensuring that any excess electrical charge is safely diverted into the ground. Typically made of copper or brass, grounding screws are chosen for their excellent conductivity and resistance to corrosion.
