Hot rolling
Hot rolled special profiles
The preheated steel is deformed plastically, creating profiles usable as finished product or roughed/pre-shaped for other processing.

Cold rolling
Cold rolled special profiles
Steel is formed at room temperature to produce precise, small-sized profiles that meet the requirements of the most demanding applications.

Cold drawing
Cold drawn special profiles
The steel is deformed plastically by dragging the material into a matrix to obtain profiles with specific shapes and dimensions, tight tolerances and complex shapes.

Manufacturing process
From design to product: quality down to the last detail
Process design
We analyze the customer’s needs to design the best production cycle, optimizing each stage.
ContinueHot rolling

Steel is preheated and formed to create pre-shaped bars, ready for further operations.
ContinueCold rolling
.svg)
At room temperature, the metal is compressed to produce highly precise, smooth profiles.
ContinueHeat treatment

Controlled heating processes optimize the mechanical and structural properties of profiles.
ContinueSurface treatment
We apply sandblasting (shot blasting) and pickling techniques to improve finishing and protect profiles from wear.
ContinueCold drawing
