STEEL CROSSPIECES FOR PERGOLA SYSTEMS


Sendzimir galvanised steel crosspieces

Obtained by profiling a galvanised metal strip using the Sendzimir method.
The Sendzimir method is a galvanising procedure that consists in passing a metal strip through a bath of molten zinc at 700° contained in a ceramic tank; elements such as aluminium are added to help the zinc attach to the steel.
Before passing through the zinc, the strip is subjected to de-greasing and stripping to remove any surface impurities and iron oxides.
The minimum coating used for crosspieces in Sendzimir galvanised steel is 200 g/m2.

Pre-painted steel crosspieces

These are made by cold profiling a galvanised and painted steel strip.
In addition to reducing the environmental impact of the crosspieces, the painting also lengthens their life, ensuring better protection against corrosion.

The crosspieces are 7/10 or 10/10 thick on request.

Tradition and innovation are intertwined at Polimetal:modern vine-growing and ancient customs are just two of the aspects we consider for producing innovative materials because it is by their installation and the use of appropriate accessories that the yield of vineyards is improved. Posts are to vines as trunks are to branches; that is why we have dedicated particular attention to their strength, durability and stability.
