All-glass railing for the upper floor
Corresponding to the railing for the folded stairs there is a straight railing entirely made of glass which was installed at the gallery on the upper floor. It is completed by a top-attached stainless steel handrail with a high-polished surface. The glass fillings were adjusted at the box-type stringer featuring notches on top. They were cast and sealed with the same technology applied for the staircase railing.
The angular frame made of steel sheet was filled on site by the customer. Subsequently it was equipped with a horizontal flat steel on the upper side. For the installation of the masked LED lighting the stair landing got vertical elements of flat stainless steel.
In accordance with the current regulations for straight railings DIN 18008-4 (Cat. B) the glass panes (of laminated safety glass) were clamped and cast in the extruded aluminium frame by means of the custom-made assembly method developed by MetallArt.
The handrail consists of an edged stainless steel U-section which was attached on the glass fillings with a rubber profile. There was no need of any gluing or grouting.
In addition to the delivery and assembly of the folded stairs MetallArt was responsible for the verifiable structural analysis for the stairs and railings.
