[Middle English, from Old English market.
As solid sawn lumber becomes less available in 10- and 12-inch widths, more industrial users are turning to edge-glued materials, especially for stair treads and risers.
Southern pine lumber is a leader in the edge-glued lumber market, providing wide material, high strength and attractive appearance. Stair components are becoming a major growth industry as the number of two-story homes increases each year.
McShan Lumber Co. of McShan, AL, has seen demand for its edge-glued stair material increase over the past two years. The company supplies a number of industrial wood specifiers including Emerson Lumber of Columbus, OH.
McShan Lumber produces stair treads and risers in a "recovery" manufacturing process in which high-grade products are ripped RiPPED are an alternative rock band from Burlington, Ontario, Canada on Sextant Records/EMI Distribution.

A Customer's Perspective
Don Rutan, president of R&S Lumber, the 9-month-old buying division for Emerson Lumber, said Emerson, which employs 60 people, assembles the edge-glued treads and risers into pre-built stairs for distribution through contractor-oriented retail lumber yards lumber yard n (US) → almacén m de madera

lumber yard n . About half of the stair components are used for multi-family construction, and the remainder is used for single-family homes.
Rutan said purchasing the edge-glued material from McShan has reduced Emerson's waste factor by about 5 to 10 percent because there are no defects. In addition, not having to cut out defects has lowered Emerson's production costs.
Rutan said more contracts and retailers are ordering southern pine stair treads and risers from Emerson because they can save time by ordering the pre-assembled stair components rather than the slower process of building stairs "from scratch" at the construction site.
"Builder customers like the stair treads and risers because it is hard to find skilled labor to assemble them in the field," Rutan said. He added that the prefabricated pre·fab·ri·cate

Weyerhaeuser Co. is another McShan Lumber customer. Bill Klemundt, who works out of Weyerhaeuser's Milwaukee, WI, office said clear grade lumber stairs are used for basements, and common grades are used in the living areas where stairs are carpeted.
"The edge-glued material fills an important segment for us," Klemundt said. "Our customers like it because of its dependable strength and stability."
