Quality and safety

Quality and safety

Our mission is quality and safety. From the very beginning, Corab's mission has been manufacturing safe and durable products in accordance with applicable standards and legal regulations.

Due to this policy, our photovoltaic systems have successfully passed numerous laboratory tests and endurance tests confirming their high quality and safety. They bear the CE mark being a confirmation of compliance with European standards. Each production stage is monitored and subject to internal quality control.

High quality
and respect for standards

Corab has an implemented and certified Quality Management System according to PN - EN ISO 9001: 2015, ensuring production at the highest quality level. Moreover, the quality of the products is supervised by an external certification body confirmed by the TÜV Rheinland Polska Monitoring + Testing Certificate granted for photovoltaic systems.

The company has been certified by the Factory Production Control ZKP / FPC for the execution of steel and aluminum structures in EXC1 and EXC2 classes, in accordance with the PN-EN 1090: 2012 standard. As for special processes related to welding elements of photovoltaic construction, they meet the quality requirements according to PN-EN ISO 3834: 2007.

Our constructions are in accordance with EN 1090 standard.


The most important standard that applies to photovoltaic constructions is the European standard EN 1090. It is addressed to steel and aluminum constructions manufactures in the European Union and countries outside of it that wish to sell products to Member States. Corab systems are made in accordance with this standard, confirmed by the certificates held.
