Union Wire Rope, a WireCo WorldGroup Brand, has been the industry leader in the design and manufacturing of wire
ropes and assemblies for more than 100 years, delivering exceptional service and unmatched support worldwide.
Union has a rich history dating back to just before the United States entered World War I. Commodity prices were
steadily increasing and headlines such as “Oil Prices Bound to Soar” were typical. Industries were experiencing
shortages of supplies and rising prices. The lack of wire rope had become so acute that drilling and production of
petroleum products were threatened.
Legend has it that a group of men were playing poker at the Tulsa Club, in the basement of the Tulsa Elks Club. One
of the players was Henry Black who was lamenting that he had no wire rope to sell. He suggested that they supply the
money and he would build them a rope mill. Black became the catalyst for the oil men who gathered later to determine
the course of action. They purchased approximately 12.5 acres of land on the east bank of the Blue River in Kansas
City, Missouri, and on May 17, 1917, Black Steel & Wire Company became a reality.
In 1927 a new management team reorganized the company as Union Wire Rope. After the War, Union was still strong
in the oil fields, but they began to seek other types of business. This led to the development of shovel and drag hoist
ropes for the mining industry, which played a large part in Union’s continued, steady growth.
In 1958 Armco Steel acquired the assets of the Union Wire Rope Corporation, and in 1988 Union was acquired by
WireCo WorldGroup, making WireCo the largest wire rope manufacturer in the United States.
Today, Union remains an industry leader in oil and gas, mining, crane and general-purpose ropes with technical
support unmatched in the industry. The Union Cut-Off Program, which is designed to calculate, log and track the
service life of Union drill lines is recognized by contractors around the world as the best in the industry.
