Support for the treatment process is provided throughout every stage by computerized control and management systems. This allows for greater operational flexibility and precision, so as to better meet the needs of a demanding clientèle, and provides additional incentives and motivations for product research and technological advances. Our plant has large yards and is equipped with lift trucks with a capacity of up to 8 tons. This allows for a suitable and rapid flow of materials during loading and unloading, as well as during treatment. If necessary, treated goods can be stored in our storage facility for long periods of time. The movement of goods and materials within our facility is safely performed by overhead travelling cranes with a capacity of up to 15 tons.
Production is divided into two shifts, employing a total of approximately 90 operators who, together with a well-trained and strongly motivated technical staff, are able to offer highly professional and efficient service, from the design stage of the fabricated articles to be galvanized through the final inspection of the finished products. In recent years, hot galvanizing treatment's scope of application has broadened. Today it encompasses a vast range of articles from every sector of the civil and industrial spheres.

The degreasing operation is crucial for obtaining materials that are uniformly pickled and therefore ready to create an optimal bond with the zinc. The installation has a capacity of 200 cubic metres. It is housed in a hermetically sealed tunnel-style pretreatment unit with a completely automated cycle of operations, equipped with an acid fume capture and abatement system. Materials are automatically immersed in degreasing baths and immersion times are set and recorded over time for every rack depending on the quantity of oil present on the material. The presence of two degreasing stations allows for longer immersion times than are possible in normal, single-tank treatment installations, which means a better cleaning of the materials. For a more effective chemical action, the solutions are heated to a temperature of 30 °C and the materials suspended from the loading racks are vibrated using a motion system that facilitates the mechanical removal of grease and oil. The efficiency of the degreasing is ensured by monitoring of the solutions through periodic analyses and by the presence of a system that continuously removes the oil from the solutions so as to prevent, among other things, an excessive amount of unwanted oil being dragged into the pickling baths.
