Visitors to the Circuit of the Americas Observation Tower and Austin360 Amphitheater are fully immersed in the experience of Formula 1 racing, thanks to red steel tubes evoking the glowing tail lights of a car left behind in the dark. Located in Austin, Texas, the tower consists of a continuously welded double-helix stair wrapped in a filigree-like diagrid, enhancing the perception it is taller than its actual height of 76 m (250 ft).

Composite steel assemblies are an efficient and popular structural option for floor construction. Figure 1 shows a typical assembly, consisting of a steel beam, metal deck, concrete slab, and shear connectors. The composite action between the steel beam and concrete provided by shear connectors creates the composite properties that make the system a very stiff and strong structural element.

Performing above and beyond with coatings for steel


Specifying high-performance coatings for structural steel framing, decking, or curtain walls can be a tall order when the application surface is located hundreds of feet above ground level. The specified coatings must protect the structural integrity of these hard-to-reach steel exposures against corrosion, while increasing longevity, enhancing aesthetic appeal, reducing maintenance, and conforming to environmental regulations.
