Priner maintains the QP-1 certification, granted by AMPP – Association for Materials Protection and Performance, a global reference in materials protection and industrial performance.
This certification attests that our surface preparation and protective coating application processes follow strict standards of quality, safety, and management.
It reinforces our operations through:
- compliance with international standards;
- high-level technical and operational control;
- safe and sustainable practices;
- and quality recognized by major contractors in Brazil and around the world.
In sectors such as oil & gas, energy, naval, construction, and infrastructure, QP-1 is often a mandatory requirement.
And for us, it is also the reflection of a culture that prioritizes excellence in every project.
