Rock Monsters Crushing & Screening Solutions (formerly Extec Texas) will be the distributor of Extec & Fintec products under the Sandvik Brand. Extec Texas has been serving the Texas, Arkansas, Oklahoma, Louisiana & New Mexico markets since 1999. Our already extensive range of products has been greatly enhanced by the acquisition of both Extec Screens & Crushers Ltd and Fintec Crushing & Screening Ltd by the Sandvik Group.
