Dolese Bros. - Oklahoma-based Dolese Bros. was founded by four brothers - William, John, Henry and Peter. The company originally focused on the construction of streets, sewer facilities and other public projects in and near Chicago. William soon decided to leave the company in the sole ownership of his three younger brothers. They changed the business of the company from contracting to operating railroad-owned ballast plants and quarries in various locations along the main lines in Kansas, Oklahoma and New Mexico. Prior to Oklahoma's statehood in 1907, Dolese Bros. Co. was already operating several quarries in the territory, as well as in Colorado and Iowa. As Oklahoma was settled, Dolese provided the many thousands of tons of crushed stone and sand that were needed to construct the young state's roads. Today, the company includes more than 45 ready mixed concrete plants in Oklahoma and seven in Louisiana, more than 330 mixer trucks and more than 15 facilities providing crushed stone, sand and gravel materials to the construction industry.

Giant Cement Company - The history of Giant Cement Company can be traced to the birthplace of the portland cement industry in the U.S. in the Lehigh Valley of northeastern Pennsylvania. This area not only witnessed the founding of the industry, but it also soon became the greatest cement producing center of the U.S., producing, at its peak, 75% of the output of the country in 1897. Prior to this date, this nation imported most of its cement from Europe. Read more.
