Since our beginning, Thompson has sought to be the industry leader in manufacturing the highest quality conductors and components.

We were the first in our industry to implement a major upgrade to pressure die-cast rather than traditional sand casting for our major bronze and aluminum fittings.

This results in a better finish, superior grain structure, density and overall strength in these components.

We are committed to monitoring our quality standing and are always seeking to upgrade and improve our materials.

White House

In our first hundred years in business Thompson has had the honor of protecting thousands of buildings including such priceless structures as the White House.
