Steel Façade and Custom-Designed Mesh Applications

Steel Façade and Custom-Designed Mesh Applications – Technical Design and Detail Guide

In high-rise buildings and rooftop architectural shell solutions, steel façade and custom-designed curved mesh systems are often designed as a secondary façade or a ventilated façade shell rather than a classic curtain wall. This study brings together the primary steel supporting frame, project-specific aluminium mesh / sheet claddings, connection brackets and installation details, and serves as a comprehensive technical design guide for Steel Façade and Custom-Designed Mesh Applications.

Steel Façade and Custom-Designed Mesh – 3D General View

1. System Definition and Fields of Application

The system is formed by fixing a steel column–beam frame to the main structure with anchors and mounting project-specific aluminium mesh or sheet panels onto this frame. Unlike conventional curtain wall systems, in many projects it works as an independent secondary façade shell or roof-top architectural skin in front of the main façade.

Custom-designed mesh claddings for industrial and commercial buildings,
Curved, oval or free-form external shell geometries,
Light but rigid façade shells in regions with high wind loads.

While giving the building a strong three-dimensional architectural identity, the steel supporting frame ensures safe performance even under high wind loads.

2. Steel Supporting Frame and Structural Behaviour

The steel supporting system consists of vertical columns, horizontal transoms, diagonal bracings and anchorage plates. This frame transfers both the self-weight of the panels and the forces generated by wind loads to the reinforced concrete main structure.

Column Profiles: Form the main spine of the curved façade and are fixed to the slab by anchorage plates.
Horizontal Transoms: Define the mounting lines of the mesh panels and increase global rigidity.
Diagonal Bracings: Limit horizontal displacements in high-rise and long-span façades.
Anchorage Plates: Provide the steel–concrete connection and work with bolted assemblies.

In this way, the shell acts as an independent secondary façade structure; façade loads are safely transferred to the ground through the steel frame.

3. Aluminium Mesh / Sheet Claddings and Ventilated Façade Shell

All external claddings are designed as aluminium panels. The panels may be full sheets, perforated mesh or project-specific patterned solutions. They are fixed onto the steel substructure by brackets and stainless-steel screws.

Joints between the panels provide a light and semi-transparent surface effect.
The air cavity behind the panels allows the system to work as a ventilated façade shell.
Thanks to its light weight and corrosion resistance, aluminium is an ideal companion for the steel frame.
Perforation ratio and pattern design are selected according to both aesthetics and daylight–shading performance.

4. Connection Elements and Installation Sequence

The steel supporting frame and aluminium panels are assembled on site using bolted and screwed connections only. This not only increases installation speed but also makes future maintenance and replacement operations much easier.

Basic Installation Steps

Positioning and fixing steel columns and horizontal transoms with anchorage plates,
Installing diagonal bracings and ensuring frame rigidity,
Mounting aluminium sub-profiles (brackets, L profiles, carrier flats, etc.),
Fixing mesh / sheet panels to the carrier profiles with stainless-steel screws,
Completing joint alignment, edge trims and corner details.

Throughout the process, wind loads, panel self-weights and maintenance scenarios are evaluated so that the secondary façade shell reaches a balanced configuration in both structural and architectural terms.
