Aluminium-conductor steel-reinforced cable coating thickness would be designated GC2. Higher strength grades of steel are designated high-strength (3), extra-high-strength (4), and ultra-high-strength (5). An ultra-high-strength galvanized steel core with class A coating thickness would be designated GA5. The use of higher strength steel cores increases the tensile strength of the conductor allowing for higher tensions which results in lower sag. Zinc-5% aluminium mischmetal coatings are designated with an "M". These coatings provide increased corrosion protection and heat resistance compared to zinc alone. Regular strength Class "A" mischmetal thickness weight coated regular strength steel would be designated MA2. Aluminium-clad steel is designated as "AW".
Her Secret Is Patience Her Secret Is Patience Her Secret Is Patience is a public art sculpture commission designed by artist Janet Echelman for the city of Phoenix. Its creation was the result of collaboration between the artist and a team of award-winning engineers, architects, planners, and fabricators. It is located downtown in the Civic Space Park across from the Walter Cronkite School of Journalism at Arizona State University. The sculpture consists of painted, galvanized steel; polyester twine netting; and colored lights. The piece cost $2.5 million. The title of the piece is a quote from Ralph Waldo Emerson and during construction it was
