We have our own hot-dip galvanising plant, where we galvanise all our products, in accordance with Standard UNE EN ISO 1461, as well as those of other clients. We have 8 treatment tanks measuring 12.50 m long and a vat that is 12.50 x 1.50 x 2.50 m which holds 320 tons of zinc smelted at a temperature of between 448-452ºC.
All our products have a galvanised finish. The latter is applied to improve steel corrosion resistance (and also that of iron alloys) by means of a thin surface coating. This is a very effective solution also in highly corrosive environments (See Table 1).
Unprotected steel products have an average useful life of only two years before their structural integrity or functionality are affected.
However, galvanised coatings applied at galvanising plants last at least ten years without any need for maintenance, even in the worst atmospheric conditions.
The basic standard which specifies the requirements to be met by galvanised coatings obtained at hot-dip galvanising plants is the Spanish and international Standard UNE EN ISO 1461, "Hot-dip galvanised coatings on products finished in iron and steel". |
