CONVEX AEBE was certified in November 2010 for the implementation of its own quality system in accordance with ISO 9001: 2008 and in March of  2019 with ISO 14001: 2015 environmental management system.
Our certificates have been awarded by TUV HELLAS one of the most recognized internationally in the field of certifications. CONVEX's quality control system includes, among other things, continuous testing of supplies, produced semi-finished products in all production and final products phases. These audits aim at the truly high quality of our products in order to satisfy the final consumer. Particular attention is paid to the durability of varnishes, which are the final protective coatings on our metal products. A test with strong solvents and chemicals (acetone, formic acid, etc.) is performed daily, demonstrating abrasion resistance and oxidative environments.
Finally, Convex complies with the standard of high-level waste management standards with significant environmental benefits such as reduced energy consumption and improved efficiency of its processes. These are Convex's ongoing commitments to improving its environmental performance.

At CONVEX we have implemented the use of the standard BS EN 1906:2012: Building hardware - Lever handles and knob furniture – Requirements and test methods - in order to evaluate the performance of our products. The results from the tests described in this standard and the evaluation of the products correspond to an 8 digit classification as defined by the standard. The tests performed at certified laboratories but also the internal quality controls enable us to classify our products based on this standard. We are in a position to issue certifications for our products referring to this classification.





The Hellenic Copper Development Institute certifies that CONVEX has the right to use the internationally acknowledged trade mark Cu+ on its antimicrobial product range.
