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.
