TUBULAR STRUCTURES

Tubular structures are structures to hold different type of equipments (electrical cables, telecommunication equipment, lighting, and others) on the top, consisting of one or more parts: a pole (structure), possibly an extension piece and if necessary, a bracket, platforms, antenna supports, etc. 

Other denominations for this product are High/medium/low voltage masts, telecom masts and lighting high masts. Metalogalva has a range of towers for each type of equipment on top. They are covered by EN 1090 and Regulation nº 305/2011 (CPR) and the product is subject to Verification of Conformity, according to the Eurocodes standards. For the medium and high voltage masts, there is specific legislation and community standards. They are covered by EN 50341 and the product is also subject to verification of conformity according to EN1090.

The range of models is defined by the material, shape, height, and conditions of use. The material of these columns is steel (sheet). The format of cross-section could be round, octagonal, polygonal, square, or rectangular. Along the length, the column can be straight, with reduction of the dimension between the base and the top (conicity), stepped (composed by one or more tubes) and depending on the height, it can have one or more shafts.

The installation of the columns in the ground can be made by base plate or planting depth. In the first option the columns have a base plate, and its fixation is made using a set of anchor bolts embedded in a concrete foundation. With planting depth, they can be installed in natural ground with or without concrete surrounding the planting depth, depending on the resistance conditions of the soil found in situ.

Certified tubular models of Metalogalva, include several heights from 8 meters to 200 meters, with different geometries, depending on height, load at top or in case of high voltage the span.
