Historic Cast Metal Construction Meets Modern Design


St. Louis, home to CastExpo’13, is a city rife with castings. A METAL CASTING DESIGN & PURCHASING STAFF REPORT


The Gateway Arch spans 630 ft. across and is 630 ft. high. While it is constructed of reinforced concrete and 5,199 tons of welded carbon and stainless steel plates less than ½ in. thick, metal castings are featured in the hardware, rail supports and elevator machinery.


Making castings from recycled metal signifi cantly reduces energy usage, mini- mizing one of the largest expenses faced by individual facilities. According to the “AFS U.S. Recycling Economic Informa- tion Study (REI),” every pound of steel recycled is estimated to save 5,450 BTUs of energy, enough to light a 60-watt bulb for more than 26 hours. Metalcasting facilities recycle more than 14 million tons of steel each year, enough energy to light the homes of Chicago for one year.


“The Runner,” a 1965 sculpture by William Zorach in Kiener Plaza, was commissioned by steel execu- tive Henry J. Kiener, who had been an Olympic high-hurdler. The 14 x 4 x 8-ft. statue is cast bronze.
