At the time of the merger between Williams and Scotsman Manufacturing, Williams was the second largest mobile office provider in the United States, with 15,000 leases leased in 13 eastern states. Scotsman operated 11 offices in four western states with a fleet of 7,500 rental units. The merger was registered as a purchase of Williams Mobile Offices from the Williams Family Trust by the Trijka Family Trust, which was owned by Scotsman Manufacturing. The new company, Williams Scotsman, continued to be managed in the family business. Growth opportunities as a national company have led Williams Scotsman to pursue its acquisition strategy. In July 1998, the company announced an agreement to acquire SpaceMaster International, Inc. of Atlanta for $273 million, including the acquisition of debt. SpaceMaster has completed the Williams Scotsman Geographic Base with 26 branches in 13 southeastern U.S. states, operating a fleet of more than 12,800 rental units. The acquisition may have generated $325 million in revenue. Williams Scotsman financed the acquisition through bank debts and the holdings of the business owners; the company refinanced the debts assumed. Williams Scotsman announced in August 2004 an international expansion with new activities in Europe and Mexico. The company founded Williams Scotsman Europe, S.L., to acquire a minor interest in Wiron Prefabricados Modulares, S.A., privately owned, in Parla, Spain, near Madrid.

Wiron owned several thousand modular units that the company leased through offices in all major cities in Spain. Williams Scotsman was given a seat on the board of directors to learn more about the company and its operations in Spain and was granted the right to refuse to sell other Wiron shares. In Mexico, Williams Scotsman opened its main office in Mexico City and a branch in Monterey. The company seized national distribution opportunities by entering into an agreement with SaniRest, a large waste disposal company with 27 branches in Mexico. Williams Scotsman introduced new products in 2002 to improve the company`s ability to serve the education market. These include Type IV classrooms that offered minimal mobility in the field. Type VI classrooms offered an economical option in renovated units recommended for short-term leases, for example.B. if the renovation of a permanent structure required a temporary alternative. With Dell Computer Corporation, Williams Scotsman introduced cyberspaces, modular classrooms equipped with computer equipment.

Customers choose desktop or laptop computers, fixed or wireless; Hardware system options include network servers and devices. Optional equipment in the classroom includes suitable furniture, a printer/scanner, a mobile wireless cart and a smart card, an electronic whiteboard that has replaced a traditional board. The new classroom structures were introduced at Williams Scotsman`s Orlando branch, with the State of Florida adopting a constitutional amendment that limited class sizes.
