Williams Scotsman Launches Stainless Steel Product for the European Modular Building Industry in Spain

Williams Scotsman International announced today the launch of
Tecno Inox S/S, a new line of stainless steel products for the modular
building marketplace, through its wholly-owned subsidiary, Wiron. A
leading company in the manufacture, sale and leasing of modular
structures in Spain, Wiron is unveiling the product at Construmat, an
international building exhibition taking place this week in Barcelona.

The new Tecno Inox S/S series is made with 304 stainless steel,
making this innovative product both structurally strong and highly
resistant to adverse climate conditions and corrosion often found in
moist, salty environments. This product line is ideal for structures
located near coastal communities such as port offices, storage
modules, maritime rescue installations and Red Cross shelters.

"Tecno Inox S/S fills a considerable void in the marketplace,"
said William Stokel, director general of Wiron. "Addressing customer
needs has always been a top priority for Wiron. Our customers told us
they wanted a versatile solution to withstand harsh climate conditions
and this product delivers on that need."

The new Tecno Inox S/S line, designed and manufactured in Spain,
balances maximum strength and durability with an aesthetically
pleasing steel finish. The features of the Tecno line represent the
inherent advantages of modular building methodology, including
accelerated building production, adaptability, and superior quality
control and risk mitigation.

According to a statement by Williams Scotsman's Chairman,
President and Chief Executive Officer, Gerry Holthaus, "Wiron has
introduced an innovative product that will greatly improve the
durability of prefabricated installations in Spain and potentially in
other international markets. This is a much-needed advancement for the
modular industry."

To learn more about the new Tecno Inox S/S product, visit Wiron at
Construmat 2007, which is being held May 14-19, 2007. The Wiron booth
can be found outside the conference on the Northeast corner of Reina
Maria Cristina and Marques de Comillas streets.
