Meteorological masts

Over the past years, 2EN has installed and monitored hundreds of meteorological masts all accross Greece and abroad, some of which on difficult terrain and extreme conditions sites.

2EN's long experience, CAE analysis and testing of mast dimensions and materials have helped developing highly reliable masts for every weather condition.

Quality management

2EN operates relying on the quality management system of international standard EN ISO 9001:2008 and produces certified products bearing CE marking.

Production series

2EN masts include models of tubular masts made of steel alloy and lattice masts made of aluminum alloy.

All masts higher than 30m are electro-statically painted in two different colors (red / white) to comply to the civil aviation authority requirements. The electrostatic paint has special marine treatment in order to be more stable in marine environment.
See the production series in the table below.

Technical Specifications

See the general specifications of lattice towers and the technical characteristics of series 2EN-LAT 500mm, 2EN-LAT 600mm and 2EN-LAT 750mm(pdf).

Design - Modeling - Certification

The design and development of 2EN masts is made with the most modern design methods using CAD-CAE specialized software.

Tubular masts are designed in accordance with the requirements of the TIA/EIA-222-F standard, while lattice masts are designed according to the specifications laid down by the Eurocodes 1, 3, 8, 9, BS EN 795.

Modelling design and assembly as well as finite element analysis techniques were integrated within NX8 platform (Unigraphics).

2EN masts are designed to withstand wind velocities of more than 50m/sec with icing. In high altitude areas, (greater than 1000m) the heavy snowfall during the winter might build ice over the guy wires, which results in heavy loading of the anchors and the structure.

Lattice masts models are certified by TUV HELLAS for the ultimate load strength diagram expressed by the mean wind speed vs. radial ice on the cables and tower body.

Patents

The Greek Industrial Property Organisation (OBI) has awarded 2EN patents with titles:

  • "Tubular mast consisting of interconnected flared tubes." (number 1006263)
  • "Aluminum Lattice bearer for various heights lattice mast construction with struts." (number 1006352) for the series 2EN-LAT 370mm and 2EN-LAT 470mm
  • "Aluminum Triangular Lattice bearer with circular columns of non-standard profile for mast construction with struts" (number 1007941) for the series 2EN-LAT 600mm
