Unique Design In Carbon Steel

The Dallas City Performance Hall is the performing arts venue in the Arts District in Dallas, Texas. For its construction, the City of Dallas entrusted the architect and engineering company Skidmore, Owings & Merrill LLP (SOM) from Chicago and the local residents Corgan Associates, Inc.
Additionally, for the construction of the curtain wall, the company Technical Glass Products (TGP) was commissioned. Due to having skills in both glazing and supporting structure, TGP designed a pleasant and strong carbon steel mullion. This is also allowing greater free spans and larger areas of glass with reduced frame dimensions.

Laser Fusing Rectangular Hollow Sections

These tailored rectangular hollow sections with sharp edges were the ideal product for Montanstahl’s laser fusion technology. But however, no butt-welding was acceptable for this high end application. So we had to make the very long section in one single piece.

Nonetheless, Montanstahl is specialized in the production of tailored steel and stainless steel mullions and transoms for curtain walls. So we made them with stripes laser-cut from plates and then laser fused these to the desired section. This technology ensures the maximum design flexibility. Due to this, the mullions are, like in this case, preferably rectangular hollow sections were the wall thickness and the section’s depth are dimensioned according to the structural requirements.

Premium Prodution: Laser Fused Sections With An Excellent Finish

The sharp edges, as well as the clean and neat geometry, make these laser fused sections a real eye-catcher. However, we cut the thirteen heavy steel mullions in S235JR, over one thousand kilograms each, precisely to length at 12,529 millimeters.
Due to this oversized length, we had to ship the bars shipped in a special 45’ open top container.

The well liked surface finish was Montanstahl’s grit shot blasted execution, which was protected with seaworthy tar paper wrapping.
