Treasure Island Casino in Las Vegas
Designed by YWS Architects of Las Vegas, Nevada, Zahner provided the engineering and fabrication of two large winged stainless steel elements at the northeast side entry of the casino. These 'wings' are constructed of steel tubing and aluminum ZEPPS Components, and were clad with an aluminum sheet sub-surface and then finished with stainless steel skins.
Each of the wings were finished with a different alloy of stainless steel, to create a color distinction between the two. The east wing was finished using a brushed stainless steel surface. The west wing with PVD coated stainless steel panels for a copper hue.
The project uses Ti-Stainless or PVD Coated Stainless, a high-performance surface that can be used to achieve gold, copper, bronze, and brass tones in stainless steel. The material is now available to the architectural community, and has a longer lifespan than similar metals such as anodized aluminum.
Ti-Stainless is a stainless steel sheet metal with with titanium alloy in its coating. There are several methods to achieve color on stainless steel. From the chemical bath process of Interference Stainless Steel to electroplating with tinting agents. Ti-Stainless is one of the most effective methods to achieve a unique tone or color on stainless is through titanium and other alloys applied to the surface of the stainless steel.In its raw sheet form, titanium is an expensive and difficult material to machine and fabricate. It has low ductility. This means that it doesn't want to bend, and that it will typically revert to its form. This is why the titanium-nickel alloy is used as a "memory-metal" for products like eyeglasses. On the other hand, this also means that titanium will take more time to machine when in sheet form.This is where Ti-Stainless has distinct advantages over other raw titanium sheet. Ti-Stainless, also known as titanium-coated stainless steel or generally as PVD stainless steel, is an more economical solution to those desiring a custom color with the longevity of titanium and stainless steel. Titanium-coated stainless steel can come in heavy gauge sheets because it is a thin layer of titanium chemically bonded with a thicker layer of stainless steel. Stainless steel coated with titanium may increase its scratch and corrosion resistance, making its durability superior to many other metal options. This durable titanium-coating makes it a high-quality option for colored metal systems.
Building the Treasure Island Winged Entrance
The project was an early use of the ZEPPS Process for building complex curvilinear forms. Each of the forms was defined digitally and manufactured at Zahner in Kansas City. The forms were each clad using flat-seam panels.
Each wing is approximately 32' tall. The units were constructed in Kansas City and transported to Las Vegas for erection. Zahner has produced multiple structures and surfaces in Las Vegas.
