COLUMBUS, Ohio--(Business Wire)--
Leading steel framing manufacturers,Dietrich Metal Framing, a Worthington
Industries company (NYSE:WOR), and ClarkWestern Building Systems, today
announced the new ProSTUD Drywall Framing System. To meet the needs of today`s
steel framing applications, engineers from the two companies are co-developing
the ProSTUD™ Drywall Framing System, the industry`s next generation of drywall
framing technology.

The patent pending ProSTUD Drywall Framing System combines innovative design
with high-strength steel to set a new industry benchmark for high-performance
drywall framing. The components in the system are lightweight and feature a
number of technological advances to enhance stiffness. ProSTUD has also been
extensively field-tested for quality and ease of installation.

"The performance benefits of the ProSTUD system are truly unmatched in the
market today," said John Roberts, president of Dietrich Metal Framing. "Not only
is ProSTUD easy to handle and install, it is a more efficient alternative to
conventional framing as it requires less steel, which benefits contractors,
architects and building owners."

"ProSTUD is an industry-changing product designed with the contractor in mind,"
said Bill Courtney, president and CEO of ClarkWestern Building Systems. "Through
creative efforts like this, we will continue to raise the bar in innovation to
provide our customers with the most efficient and cost-effective steel framing
products."

While Dietrich Metal Framing and ClarkWestern Building Systems are co-developing
the ProSTUD Drywall Framing System, they will be independently selling ProSTUD
products. The first manufacturing facility conversions for ProSTUD Drywall
Framing System will take place in the fourth quarter of 2009. For more
