Sidenor 2022 Sustainability Report

31 For Sidenor, the most important value consists in meeting the needs of our customers, and one of the most important needs is the technical capacity of our product. To that end, the Company has established, for many years now, a Customer Technical Assistance Department (CTA), whose sole objective is to serve as a point of contact with the customers in order to cover all their needs regarding the technical performance of the product that we supply. In this respect, the CTA Department performs two types of customer services: 1. Pre-sales service, with two priority activities:  Most suitable design of Sidenor’s product in favor of better performance and optimal adaptation to customer processes.  Management of approvals : documentation, audits, initial samples… 2. After-sales service , focused on:  Integral management of complaints.  Product optimization (enhanced performance, decrease in costs…)  All types of technical queries For this purpose, the CTA Department relies on a team of highly experienced professionals in the field of metallurgy, heat treatments as well as special steel products and processes, which are fully dedicated to customer service. This service implies a differential value for the Company, as it allows us to accompany our customers along their continuous improvement process and boost their competitiveness with products that fit their needs.
