The manufacturing process of special steel profiles
From raw material selection to the finished product
Focus on specific customer needs and technical expertise in engineering are the strengths of Calvi. These translate into a production process oriented to the highest quality and able to limit costs and reduce waste, avoiding any possible waste of raw material.
Quality control throughout the production cycle is essential to ensure that final products meet the required standards and customer specifications.
The manufacturing process begins with selecting the best raw materials, usually laminated and peeled round steel bars.
Alternatively, the raw material is purchased in rolls or as semi-finished products obtained by rolling or extrusion processes.
We only use steel from suppliers selected on the basis of their manufacturing process and quality standards. Before starting production, the raw materials are thoroughly checked to ensure that their properties comply with the required specifications.
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
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
The material is pulled through a die to produce complex and precise profiles with tight tolerances.
ContinueFinishing
The profiles are cut, straightened and prepared for shipping, as specifically requested by the customer.
