Exclusive stringer stairs with steel balustrade

2021, Gunzburg

With a sophisticated staircase design and seamless surface appearance, the stringer stairs with steel balustrade present themselves as an impressive overall installation.

Elegant color scheme

When building a new private villa on a hillside, the client attached great importance to a spacious spa area, a smokers' lounge and a green living room. The interior of the upscale residential property was designed in an elegant dark brown color scheme with high-quality materials and surfaces. With large window fronts and an appealing lighting concept, a unique living environment was created. With the planning and execution of the sculptural stringer stairs with steel balustrade, METALLART succeeded in creating a convincing staircase installation that consistently blends in with the exclusive overall concept of the private property.

Sculptural connection

The steel staircase is the central connecting element between the first floor and the upper floor and blends into the stylish living ambience. The rounded staircase construction leads upwards with one and a half even turns and ends in a straight bridge on the upper floor. The step construction is designed as a closed folding structure. The sculptural character of the stringer stairs with steel balustrade is enhanced by the smooth steel soffit lining, which was welded exactly between the stringers to match the flight of stairs. This design element was finished with the entire stringer stairs with steel balustrade with a liquid metal coating applied on site, giving it a completely seamless and homogeneous surface appearance.
