Steels
Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality. The constant quality of the supplies allows to have repetitive parameters in mechanical processing and a greater control over deformations during heat treatment.
Machining
Precise cuttings of small and big series are guaranteed by the employement of latest generation automatic saws that were projected and realized in order to guarantee precision standards required by customers, reducing processing wastage.
Quality
The certification and introduction of the Quality System management allowed M.T.Acciai to improve not only its efficiency, but also the quality that is offered, in order to better meet our customers’ needs.
