Certified design, development and traceability.

We work with the highest quality standards, from project to construction.

We consider quality as the way of operating the company, as one of the fundamental pillars of our work and differential attribute of our products and services.

Our quality system is based on constant training for our staff, the traceability of each product unit and the certification of our processes, in addition to the constant support of our clients.

How do we do it?

Through original software, our quality system ensures traceability for each unit of product. In the profile development stage, all initial tests are carried out to achieve the Technical Aptitude certificate issued by Bureau Veritas.

Once the Technical Aptitude has been achieved, each unit produced has a registration number engraved on the shaft and a barcode label that guarantees the traceability of the entire production process, including, among others:

  • Raw material used

  • Manufacturing date

  • Equipment parameters

  • Responsible in charge at each stage of the process

  • Specifications, tests and measurements


This entire control system is based on the requirements of the application standards of each line, and it has the certification of Bureau Veritas by lot referenced to each product registration.
