Stainless Steel Profiles for a Curtain Wall

Façades are often the business card of a building. 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.To get more news about Stainless steel green facade, you can visit mesh-fabrics official website.

Montanstahl brings over 30 years of industry experience and excellence in the production and supply of high-quality special shapes in steel and stainless steel. Our laser welded curtain wall sections differ considerably from conventional fillet-welded sections.

The laser weld seam is small, neat and barely noticeable. Montanstahl usually manufactures its laser profiles by welding together high precision laser-cut flat bars and occasionally the stainless steel profiles are build up using press brake sections, hot rolled or extruded special shapes.In a steel-glass curtain wall, the mullions and transoms must grant sufficient strength to support the load of the façade. 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 façade will result.

Extruded aluminum profiles are the most common material for curtain walls. 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.Montanstahl laser welded curtain wall sections are custom-made. Structural engineers can specify the width, height as well as the web and flange thicknesses according to the static requirements.

They also calibrate the weld penetration precisely, according to the structural load requirements of the curtain wall and minimizing distortion and stress.

It is also possible to combine different material grades, so called black and white combinations, where some parts are in mild steel and other parts in stainless steel. This all results in a wide matrix of solutions that givetotal design freedom to architects and engineers.

Another plus is the sharp contour of the shape that generates a precise cut between light and shadow. Architects appreciate this very much.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 façade. The taller the façade the greater the depth of the section and/or steel masses used in the flanges.

The most popular mullion and transom designs used in steel-glass curtain walls are rectangular hollow sections (RHS) and stainless steel tees.
