Steel stringer staircase BERLIN – Elegant and durable

Outdoor stairs are always a special highlight in the garden With its convincing design, the BERLIN outdoor staircase meets all requirements, be it in terms of functionality or weather resistance. The simple and solid design impresses with its combination of practical properties and a puristic look. The hot dip galvanized outdoor staircase BERLIN has the particular advantage that it can be individually adapted.

The special feature of the steps is again in the foreground here: an elegant and optically unobtrusive honeycomb structure ensures particularly high stability on the one hand and prevents the formation of puddles and ice on the other. Just like the heavyweights of the other editions of the BERLIN Premium external staircase, the Premium Edition also impresses with its straight lines and the associated puristic appearance. The end-to-end precision standpipe ensures absolute stability to hold this heavyweight with its enormous material strength made of 0.2 in thick steel securely. The spiral staircase is made of hot-dip galvanized steel and is therefore particularly weather-resistant.

German Steps

The great feature of the BERLIN Premium outdoor staircase is the structure of the steps. The BERLIN Premium has steps with an elegant honeycomb structure and thus offers a particularly high-quality look. Just like with the expanded metal edition, no puddles and therefore no ice can form, so you can enjoy safe walking comfort at any time of the year. A steplessly adjustable incline from 7.09 in to 9.25 in ensures maximum walking comfort.

BERLIN Premium outdoor staircase consistently follows the German Steps construction kit principle and, despite its massive size, can be assembled by just two people. The winding of the stairs can be done either to the left or to the right.

The spiral steel staircase BERLIN Premium is available in different versions. You can also choose between four different diameters from Ø 47 in to Ø 70.87 in. The larger the selected diameter, the larger the free passage widths, and the tread depths. You can find more information in the technical drawing and in the table below.
