The dimensions on the drawings are the final dimensions after the hot DIP galvanization. The design of the fittings is indicative; However the mentioned dimensions on the drawings are the critical ones.

Electric power fitting GALVANIZATION

The fittings shall be delivered hot DIP galvanized according to the following specifications:

· The Zinc of the electric power fitting that shall be used shall have the quality of minimum category prime western according to the category Zn 98.5 according to ISO-1461.
· Then washed out with water and then flux treated and dried out.
· The hot DIP galvanization shall be made in a Zinc bath of temperature 450° C and of Zn-composition min. 98, 5%.

· The galvanization thickness of the electric power fitting shall be in average 86μ M 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 78μ M 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 spots with too small or too big galvanization thickness otherwise the pieces will be rejected.

· The galvanization shall stick very well on the steel structure; It shall not be removed as a film but shall be as one with the steel body

C:
Electric power fitting Testing:
The fittings shall be fixed in a mechanical testing device as similar as possible with the assembly later during use
D:
Electric power fitting PACKING:
All materials of the electric power fitting shall be packed in wooden / bags cases of maximum weight of every wooden box 25 kg. The wooden cases shall be suitable for the transport of the pieces without damaging the galvanization, and shall allow air to circulate and the used wood shall be completely dry in order to avoid any corrosion of the fittings.
