Lattice Masts
studied in terms of static & structural adequacy
Lattice masts of ISTOS RENEWABLES have been developed by experienced engineers as to the static and structural adequacy in accordance with:
- Eurocode 1: Actions on structures (ΕΝ 1991)
- Eurocode 3: Design of steel structures (ΕΝ 1993)
- ISO 12494 standard: Atmospheric icing of structures
- TIA-222-G standard: Structural Standard for Antenna Supporting Structures and Antennas
- IEC 61400-12-1, ed.2: Power performance measurements of electricity producing wind turbines

Technical Specifications for all modelsTechnical Specifications for all models
- Treatment: Hot dip galvanizing
- Final treatment: electrostatic paint in UV resistant colours compliant with Civil Aviation Agency demands (Red & White)
The strength of each mast model depends on its height as well as wind and icing conditions.

Apart from the above standard mast models, our company is able to develop customized mast models that meet the specific requirements of our clients.
Notes:
* Technical specifications are subject to change due to the continuous improvement and development of masts.
** Strength refers to a specific layout of the anchors, which will be provided by Istos Renewables Ltd.
*** Ice thickness refers to evenly distributed ice with a density of 500kg//m3
