Façade design with EGLA-DUO 4222 for South African National Roads Agency Limited (SANRAL)

SANRAL - the South African National Roads Agency Limited - is responsible for the management, maintenance, and development of the South African road network. Their newest office building is located in Bellville, a borough of Cape Town.


With an average of 300 days of sunshine per year, Cape Town is one the sunniest regions in the world. Therefore, it is no surprise that sun protection was an important issue for SANRAL´s new office building.

As a result, the new office building near Cape Town received a functional, decorative exterior façade. MAC Architects decided on a partial mesh façade with W.S. Tyler Architectural Mesh. In addition to its aesthetic appeal, the mesh façade should also serve as an effective sun protection for the offices behind it.

W.S. Tyler, together with the architectural firm, developed the new wire mesh EGLA-DUO 4222. This mesh type is made from round and flat wires and provides an extensive brilliance. With an open area of 46%, it provides effective shading while ensuring a good view from inside to outside.

The SANRAL office building gets its distinctive character due to the individual form of the façade cladding, which consists of 1585 m² of W.S. Tyler Architectural Mesh. Due to the special geometry of the façade areas, the 66 mesh elements were supplied ready-to-install with partially curved sides and accordingly adapted edgings.
