Industrial Stack

These products are designed to be used on heavy duty industrial smoke stacks and chimneys. They often require that lightning protection products be lead covered for corrosion resistance and material protection. These stack materials are made out of copper, but you can also find stainless steel air terminals depending on specific applications and considerations. All lightning protection materials on the top 25’ of a stack must be lead covered.
