| Giant steel frame is protected from corrosion  The completion of the steel frame that will support the world's largest high-definition video board was celebrated March 31 with a topping out ceremony that featured former Dallas Cowboy's defensive end Ed "Too Tall" Jones. Jones placed an American flag on the final girder, which was hoisted more than 110 feet in the air and secured atop the 500,000-pound steel frame that will hold the 165,000-pound HD video board. The girder measured 40 feet long with a 10-foot depth of bracing steel. "This is the world's largest high-definition video screen and we will be getting that certified by the Guinness Book of World Records", said Richard Ballard, vice president of sales for Panasonic Enterprise Solutions Company, manufacturer of the display. With 16,000 square feet of viewing area, the new display is 40% larger than the current world record holder at Dallas Cowboys Stadium. Galvan Industries galvanized all 250 tons of structural steel used in the construction to protect it from corrosion. Galvan has worked on many large projects at the speedway over the years, but this one was special. The design consists of six vertical trusses that stand 135 feet tall. Horizontal beams, platforms and diagonal bracing add support so the screen can withstand gusts up to 100 miles per hour. write your comments about the article :: © 2011 Construction News :: home page |
