Serbian Orthodox Church of Holy Trinity




Double lock standing seam

The Church of Holy Trinity is very proud of its history and architectural heritage so we worked closely with them and SIA Architects to understand their requirements for the refurbishment.

They were insistent that the metal chosen for the roof domes must not change in colour after installation.

From experience, we knew that when creating domes from metal, the substructure is complex and there is zero tolerance for deviation. Together we created a design for the steel that would work.

Proven profiles, precious metals

We used a standing seam for each of the domes to create vertical, unbroken lines and opted for high-quality VM Zinc from France for its structural flexibility.

The long-lasting Quartz Zinc treatment will ensure that the domes’ velvet grey colour holds over time. Its natural-looking tones were also chosen to blend well with other construction components, including the light grey façade that they desired.

Lifelong value

Completed in 2013, the Church of Holy Trinity stands proud as a dominating presence with its spectacular zinc domes.
