Next to our special and standard profiles, we supply an interesting range of system profiles for the architectural, building and construction industry. Specifically we do offer heavy-duty laser welded steel and stainless steel curtain wall sections, hot rolled solid steel window sections and thermally broken steel window sections.
The company’s German branch – Montanstahl Architectural Steel Profiles GmbH – is specialized in the supply of architectural steel profiles for curtain walls and façades. The sections are laser welded and differ considerably from conventional fillet-welded sections. They are sharp-edged and the seam created by the laser welding machine is very small, neat and barely noticeable. Architects very much appreciate the sharp contour of Montanstahl’s mullions and transoms because it allows a distinct separation between light and shadow. Furthermore, the weld penetration can be calibrated precisely according to the structural load requirements of the curtain wall minimizing distortion and stress. These high span facade profiles can be hollow sections (SHS or RHS), T-sections or free forms. They are custom made and structural engineers are free to design the width, height, web and flange thicknesses according to the static requirements.
In 2014 Montanstahl partnered with MOGS, an Italian company specialized in the development and distribution of complete thermal barrier steel window systems, founded the company OTTOSTUMM.
OTTOSTUMM supplies steel window sections that are unique in their aesthetics & design while guaranteeing energy-efficient insulation. Depending on the climatic environment, the regulations on thermal performance and national heritage guidelines, the architect can choose among a large variety of different window systems and designs to match the requested architectural style.
The window profiles are available in the classic strip galvanizing, as well as in bright steel (not galvanized), cor-ten steel, stainless steel (1.4404 / 306L) and in architectural bronze.
