Back to the map

01The company

Delna was founded in 1971 from an industrial project realized by a group of entrepreneurs. The aim was to bring to the market a service of stockpiling and coil pickling that would accommodate the new dimensions of steel mill products and the principles of eco-sustainability of the plants at the same time.

The far-sightedness of the founders has, over time, translated into an entrepreneurial success that in 50 years of continuous development has achieved ambitious goals: exceeding one million tonnes per year and over 18 million tonnes processed in the period.

02Unloading Reservation

The material is delivered and collected by customers' own vehicles. In order to avoid long waits and crowds of vehicles in the forecourt in front of the entrance, each haulier books the day and time in our online calendar.

At the entrance, an electronic display board shows the number plate of the vehicle authorised to access the site, thus enabling the equal distribution of loads and unloads throughout the day.

03Large Storage Room

180,000 square metres for the storage of coils and 15,000 square metres for the storage of wire rods allow Delna to be an "external warehouse" for its customers: this allows greater freedom of purchase independent of the possibilities of storage in internal warehouses and a greater assortment.

Customers can expand their assortment of both black and pickled and ask Delna to deliver batches every day, even in small quantities.

04Ecological Plants

Delna has facilities for the roasting furnace separation of spent hydrochloric acid from iron solution. The technological cycle returns a solution of regenerated hydrochloric acid with a yield of 98% to the pickling plant, while the powdered iron oxide obtained from the process is used by other companies for the production of ferrites and permanent magnets.

The water used for washing is treated with lime and flocculant to separate the inert sludge, which is thickened by the filter press and then disposed of. In this way the water is completely purified before being discharged into surface water courses.

The crystallisation plant recovers the regenerated sulphuric acid from the recycling of spent baths and prepares it for reuse in the pickling process.
At the same time, it produces ferrous sulphate heptahydrate crystals that can be reused both in agriculture and for water purification.

05Short Processing Time

The transformation of the material is carried out with a maximum of a three-day lead time from receipt of the customer's order.

The scheduling of pickling and/or cutting is agreed with the customer on the basis of his daily needs. Thanks to Delna's great flexibility, programming is actually done by the customer himself, simply by making a pickling or cutting request.
