Kalzip official partner
As the single company that both supplies and installs the material, responsibility is undivided and the warranty comes from one source.

Airport-scale experience
Five airport terminals including a single 440,000 m² roof; we know large spans, curvature and wind-load problems.
- 03
International site teams
We installed with our own crews in Kazakhstan, Uzbekistan and Tanzania, managing logistics and customs.

Single responsibility from design to handover
Detail drawings, structural verification, fabrication, installation and watertightness tests by the same team; no subcontractor layers.
How we work
A closed roof in four steps.
- 01
Survey and design
We review the architectural design, roof pitch and purlin spacing, then define the system and material thickness.
- 02
Details and structure
Wind uplift, thermal expansion and drainage calculations are made; installation details are drawn.
- 03
Fabrication and logistics
Standing seam sheets are roll-formed in one piece on site or in the factory; transport and crane plans are prepared.
- 04
Installation and handover
Our certified crews install, then hand over the roof with water tests and inspection reports.
