Quality & Certificates
International standards in production and quality assurance
Our Quality Policy
At Altıntaş Çelik, quality forms the foundation of our business approach. From raw material procurement to engineering, from factory manufacturing to on-site assembly, quality control meeting international standards is applied at every stage.
Over 80 years of industry experience has enabled us to make quality not a goal, but a natural business practice. Every steel element undergoes dimensional inspection, weld examination, and surface preparation before leaving our factory.

Factory-Controlled Production Advantage
All steel construction manufacturing is completed in controlled conditions at our Pınarbaşı/İzmir factory. No on-site manufacturing is performed — this is Altıntaş Çelik's fundamental quality principle.
The controlled factory environment provides distinct advantages in consistent quality, precise dimensional accuracy, and workplace safety compared to on-site manufacturing.
