Application
Towers are used for radio-relay communication and telecommunication..

Main features
Tower is truncated 3-side latticed pyramid.

Position
The lowest ambient temperature down to –400 С;
Black ice in the 3rd zone;
Wind loads from the 2nd to the 4th zone;
Load of 2 antennas of 2,0 m diameter, 4 antennas of 1,2 m diameter and 4 antennas of 0,6 diameters at the upper mark.

Design standards
According to SNiP (Building Norms and Regulations).

Structure
Structure of the tower is made from separate elements interconnected by bolts Strips and horizontal elements of towers are made of hot rolled steel profile of tubular cross-section (yield strength 245...255 N/mm2). Diagonal elements are made of hot rolled angles (yield strength 245 N/mm2). Inside the tower is equipped with stairs for assembly, safeguarding profile and special brackets for cable fastening and rest grounds.
Structures are made according to SNiP (Building Norms and Regulations)..

Anticorrosive coating
All elements undergo hot galvanizing. Depth of coating is not less than 90 micrometers, for fasteners – 40 micrometers.

Signal paint
Adjusted with the customer. It is made by the joint-stock company Ltd. UAB “Vilniaus universaliųjų metalo konstrukcijų gamykla” at the factory. Painting in two layers: the first – epoxy priming, the second – polyurethane paint. Depth of the coating is not less than 120 micrometers.

Standard delivery of materials
Set of metal structure elements and necessary fasteners, assembly and cable stairs and elements for fastening inside the tower. All materials are labelled and packed for transportation of the tower to the place of assembly.
