We can design several solutions as far as the flag poles s concerned, from the simple galvanized columns up to customized aesthetic solution.
Columns of every type can be emplyed to this purpose :
- Conical columns with circular cross section, taper ratio 10 mm/m or 14 mm/m, obtained by cold forming of trapezium of pressed steel plate and subsequent external longitudinal welding.
- Conical columns with polygonal cross sections composed of one or more elements joined by forced overlapping obtained by cold forming of trapezium of pressed steel plate and subsequent external longitudinal welding
- Cylindrical stepped columns, manufactured employing induction longitudinally welded tubes UNI EN 10219/2, steel grade S235JR UNI EN10219/1, stepped at one end by press and joined by means of circumferential welding nearby the steps.
The flag pole kit t is composed of 1 pulley to be fixed at the base of the column and 1 terminal to be fixed on top with pulley and aesthetic sphere.
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
All steel structural components according to CE standard are manufactured according to EN 1090 execution class ECX2, certified by third party according to European directive UE 305/2011.
