Mixed-use residential and commercial development in Kraków

Technically complex railings, Juliet balconies and staircase metalwork developed to meet a demanding architectural concept.

Mixed-use development in Kraków with railings by Silma Tools

Project scope

One architectural language across facade and interior.

  • 20 Juliet balconies
  • 20 balconies, averaging 6 linear metres of railing each
  • two staircases
  • technical design, measurement and manufacture
  • transport and installation

Engineering challenge

Complex geometry at every production stage.

Silma translated the architectural requirements into complete manufacturing documentation coordinated with the architects and site management. The form needed to fit the character of the surrounding area and the architectural requirements applying to the development.

The work involved difficult round-to-square section joints, vent and drainage openings for galvanising, control of zinc coverage, removal of zinc runs in restricted areas and careful installation without damaging the coating.

Delivery process

From technical design to controlled installation.

01

Engineering

Manufacturing documentation developed and coordinated with the project team.

02

Fabrication

Complex welded connections prepared with the openings required for galvanising.

03

Surface protection

Galvanising, dressing of zinc runs and powder coating to the architectural colour scheme.

04

Installation

Accurate handling and installation in difficult site conditions without coating damage.

Outcome

Architectural intent translated into repeatable execution.

The installed metalwork retains the characteristic geometry, colour scheme and decorative detailing of the architectural concept.

The staircases use painted carbon steel with gold-coloured PETG decorative elements. The public description omits the exact location, investor identity and parameters not approved for publication.
