Quality and Safety


SIMI has been promoting Quality over the years as a differentiating factor of the service provided, based on the needs of our Customers.

In 2004, SIMI obtained the certification according to the ISO 9001 standard, thus validating the good practices aimed at the continuous improvement of its processes and always focused on the satisfaction of its customers.

In a market where the competitive advantage achieved by Quality is ending, as Quality will no longer be a factor of differentiation and will become a basic requirement of the service, it is necessary to introduce new differentiation factors such as innovation, tailored made solutions, optimizing resources and reducing costs to maintain these achievable advantages and promote an add value to our clients.


SIMI currently has the latest welding technologies with the aim of increasing productivity and the quality of the final product, being certified according to the ISO 3834-2 standard "Quality requirements for fusion welding of metallic materials - Part 2 : Comprehensive quality requirements ".

Equipped with a Welding Department and a Qualified Welding Engineer (IWE / EWE), the most appropriate processes are defined for each project, taking into account client requirements, maximizing productivity and quality required.
