About us
Where innovation meets durability in metal roofing and facade cladding.
Istanbul-based Davtek designs, supplies and installs metal roof and facade cladding systems for residential, commercial and infrastructure projects.
Our story
A team that came from the field
Davtek is an installation and supply company specialised in metal roof and facade cladding. As the Türkiye territory agency and official partner of Kalzip aluminium standing seam systems, we run the whole process from genuine material supply to certified installation.
Our founders spent years on site in the industry, gaining installation experience on projects demanding in geometry and scale, from large-span airport terminals to curved transport buildings. That experience underpins our detail-solving, structural verification and watertightness-focused approach on every project today.
Beyond Türkiye we have installed with our own crews in Kazakhstan, Uzbekistan and Tanzania. With a customer-centred approach we have built long-term partnerships in both the public and private sectors.
