Overview
Koppers is a global company and a leading
integrated producer of carbon compounds and treated
wood products for the aluminum, steel, chemical, rubber, railroad
and utility industries.
Koppers is a leading distiller
of coal tar, a by-product of the transformation of coal into coke.
Koppers distills coal tar to produce carbon pitch, refined tar,
roofing pitch, creosote, carbon black feedstock and chemical oils. The
chemical oils resulting from distillation are used to produce naphthalene and phthalic
anhydride (PAA).
Koppers carbon materials and chemicals are essential
to the production of aluminum, steel, plastics, resins, treated
wood and rubber products. They also increase the durability of
many products including railroad ties, utility and transmission
poles and marine pilings.
Koppers is also a leading producer
of treated wood products. Treated wood creates more durable structures
that resist decay, increasing safety, reducing replacement costs
and preserving valuable forests.
Koppers has been serving the railroad industry
with treated wood railroad ties and railroad crossing panel products
for over 20 years. In North America we are the largest provider of railroad crossties
and are known for our pre-plated crossties. We are also a leading
producer of wood poles for the electric and communications
industries, along with treated wood for heavy-duty construction.
