· The galvanization thickness of the Crossarm shall be in average 80m thick! 
On an isolated piece or on a small part of the surface the thickness can be a little lower,
however on all pieces and on all surfaces the minimum thickness shall be 78μm and
the average weight in relation to the galvanized area shall be 610 gr/m².

· The pieces of the electric power fitting shall be after HDG free from black stains, enclosures of dirt, knobs, 
bubbles or any other surface defects. The HDG shall be smooth and uniform in the entire piece without any
