Steel Profiles for Curtain Wall Building

Over the last decades, steel has been recognized as a versatile high-end material and became a dominant design element in an increasing number of building facades and curtain wall projects. The Glass Facade – an Eye-Catcher Modern curtain wall designs are generally regarded the business card of the modern buildings today. The lobby gives a first message of prestige to its visitors when entering the building. Therefore, it is no surprise that architects and designers accurately select and define materials for these areas. More and more of them turn to stainless steel for their curtain wall projects. The Right Solution for a Prestigious Curtain Wall Facade For a steel-glass curtain wall building, the mullions and transoms must grant sufficient strength to support the load of the building facade. The weight of the glass panels and the resistance against the wind load assure this. The more glass and less mullions contrators use, the more majestic and transparent the facade will result. Extruded aluminum profiles are the most common material for curtain wall systems. However, they are not strong enough for such high span facades. Here the preferred choice clearly becomes mild steel, thanks to its three times higher e-modulus and for more prestigious applications stainless steel. Steel Curtain Wall Profiles The majority of curtain wall mullions and transoms are designed with a sideline of 50 or 60 millimeters. The depth, or height of the sections, results from the structural requirements of the facade. The taller the facade the greater the depth of the section and/or steel masses used in the flanges. In the current market, the most popular mullion and transom designs used in steel-glass curtain walls are rectangular hollow sections (RHS) and stainless steel tees. Especially laser welded RHS not only have crisp outside corners independent from thickness, but they are optimized to the required loads. Increasing the wall thicknesses, mainly in two opposite flanges, is easy. Therefore, the majority of laser welded RHS used as mullions in facades have different material thicknesses in flanges and webs to increase the moment of inertia.
