Metal indoor staircases are extremely load-bearing, do not warp, and allow significantly slimmer, more modern constructions. They are also absolutely maintenance-free and do not squeak or creak even after many years of use.
Combinations of a robust steel or stainless steel supporting structure with treads made of solid wood or glass are particularly popular. This combines the minimalist elegance of metal with a warm living atmosphere or maximum transparency.
No. Precise welding techniques, elastic sound insulation elements at the wall supports, and the combination with wooden or glass treads effectively minimize the transmission of impact noise.
For limited living areas, compact space-saving staircases, elegantly winding constructions, or metal spiral staircases are ideal. These constructions maximize headroom while requiring a minimal footprint.
Indoor staircases must comply with the state building codes and DIN 18065. These precisely regulate the step formula (ratio of tread depth to rise), the usable flight width, and the required railing height for fall protection.
Yes, every indoor staircase is precisely adapted as a made-to-measure solution to the on-site structural conditions. Using modern 3D preliminary planning, ceiling openings, step dimensions, and pitch angles can be coordinated with millimeter precision.
Safety is guaranteed by a maximum bar spacing of 12 cm on the railing and slip-resistant tread surfaces. With open treads, discreet components can also be integrated to reduce the clear gap between the steps.

After a long search, we discovered this shop. Great service, very friendly and competent advice. Top quality. When purchasing from the online shop, the various options are clearly displayed, which makes selection and purchase easier. Payment also possible via PayPal. The delivery announcement by the forwarding agent worked well. The window grille was carefully packed and delivered. We will definitely be ordering more window grilles here. Purchase August 2025; UPDATE: We have become repeat customers and bought another window grille from Kirchberger in November - absolutely satisfied - fits together perfectly.
