Which zinc coating is ideal for me?
The service life and therefore the choice of coating is dependent on the soil type. Soil resistance, soil moisture, chloride content, sulfate content and primarily the PH value are relevant here. Batch-galvanized posts impress with their relatively thick layer of zinc for more demanding air and soil conditions. In the event of soil conditions with a neutral or PH value higher than 7.0, a strip-galvanized post may be used as an alternative.
Please note the formation of a covering layer.
Do not position the new batch-galvanized and strip-galvanized posts immediately. Storage outdoors enables an anti-corrosion covering layer to form first. That also offers protection over a sustained period of time after the post has been positioned in the soil. The posts can be exposed to rain but avoid stagnant.
Batch-galvanizing
This involves the individual profiled posts made from machine steel in accordance with EN 10025-2 being galvanized individually in accordance with EN ISO 1461. A complete zinc layer of 70 – 80 μm is formed.
Strip-galvanizing
This involves the steel strip (Machine steel EN 10346) being galvanized before the shaping process, which forms a zinc layer of up to 35 μm. Cut and punched edges are not galvanized, but will however be protected by the surrounding surfaces due to the long-range effect of the cathodic protection. Weatherproof.
Weather-resistant structural steel
Weather-resistant structural steels form a dense barrier layer under the actual layer of rust as a result of weathering. It offers ideal protection against corrosion. Due to their unique weathering resistance and the characteristic patina, these steels are employed in architecture and are ideal for viticulture.
