Certificates and Standards

Proko Construction Industry applies requirements of ISO 9001:2008 Quality Management System and associated standards at Headquarters, Factory and Construction Sites. We are certified with OHSAS 18001:2007 Occupational Health and Safety Management. As a result of applying these requirements and relevant standards along with our “Zero Tolerance Approach” to Health and Safety issues, we gladly didn’t face any incidents resulting with severe injury or decease since our establishment. We believe in continuous education and providing every opportunity for our team to improve themselves both in their profession and regarding Health and Safety issues. 
We also possess ISO 14001 Environmental Management System Certificate. As a company aware of its environmental responsibilities we take all necessary precautions to minimize our impact on the environment.
We mostly take Eurocodes as our guide for enginnering studies but we also have the capabilities to make designs and prepare calculation reports in any code required including but not limited to ASTM. As being experienced in designing buildings in First Degree Seismic Zones we are also capable of providing safe designs for the buildings within these regions.
Our fabrication process is certified under the requirements of EN-1090 Execution of steel structures and aluminium structures. Our certified process and our application of all relevant standards not only enable our end-products to be labelled with CE Mark but also to be safely and legally used at every structure within EU. With EN-1090 we also provide Traceability of the material throughout our fabrication process. As a result of traceability records and documentation, all of our processes can retrospectively be tracked down. Proko applies requirements of ISO 3834-2: Quality requirements for fusion welding of metallic materials and associated standards to ensure a correct and safe end-product. Our welds are predefined and implemented with the supervision of International Welding Engineers and executed by our Certified Welders. Our QC team strictly applies controls at every stage of fabrication to minimize faults and to keep end-products within limits of tolerances set in aforementioned standards and technical specifications of the projects.
