The electrolytic zincing is done only on the outside with an entrance in the interior spaces on distances of 20-25mm and with a thickness of the zinc start of 0.01mm, which can reach 0.02mm depending on the zincing time.
The thicknesses of the pipes used and which frequently exist in our stock are in the range of 1.5 and 5mm, but we can supply and deliver round, rectangular and square pipes with thicknesses greater than 5mm.
