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.
