Telecommunications mast


The particularly slender shape, the assembly simplicity and quickness , as well as the cheaper prices compared with the lattice works structure, made it possible that the monotubular steel column founds a wide application in the field of telecommunications.
The experience gained in designing and manufacturing such supports, proposes ourselves as qualified suppliers among bigger Italian company in this field.

High mast with polygonal cross section, for telecommunication antennae support, manufactured under certified quality check according to  ISO9001 by authorized processing center according to DM 14/01/08, composed of one or more elements joined by forced overlapping, obtained obtained by cold forming of trapezium of pressed steel plate and subsequent external longitudinal welding carried out by approved automatic process (submerged arc) and welding check according to EN ISO 3834.
Provided  for the Anchorage to the basement by direct burying or by means of base plate and anchor bolts .

Steel iron works such as cable tray rack, climbing ladder, platform and brackets for antennae support .

All steel structural components are manufactured according to EN 1090 in execution class ECX2, certified by third party according to european  directive UE  305/2011.

Protection against corrosion by means of hot dip galvanisation obtained with the following cycle: degreasing; pickling, washing, fluxing, pre heating; hot dip galvanization in melted zinc bath at 440÷450°, with minimum percentage of zinc into the bath ³ 98.5%. Coating obtained according to UNI EN ISO 1461 with minimum thickness 55 microns et average 70 microns.

External painting, if any, with colour from our colour card, rough effect, obtained with thermosetting powders cycle including: cleaning from zinc coating burs; smoothing of the surfaces by means of a light mechanic device; cleaning of the surfaces in order to eliminate grease or dirty and create a good adherence base; application by means of electrostatic spray of polyester powder suitable for galvanized surfaces for outside installation, in order to reach  60/80 micron thickness; polymerization into oven at constant temperature of approx. 200° for 40-50 minutes, package for each column, by banding with tissue 100% polyester, (no pluriball), in order to avoid damages during the handling phase. The characteristics of the obtained coat will be: average thickness  60 micron, resistance to checkering test  ISO2409, resistance to crash test to UNI8901

In order to design the mast for telecommunication it is necessary to know the following data:
– Installation site 
– dimensions, weight and location of antennae 
– deflection limits on top, if any 
– height
