We have been providing a full range of steel fabrication services for our clients which includes Top Global Contractors all around the World.
We fabricate all structural steel components at our Steel Fabrication Facility having an annual capacity of exceeding 6.000 tons. With the help of our comprehensive machinery, experienced technical team and quality system our fabrication process becomes defect-free. As we embody all of technical and structural services related to construction, we are able to minimize faults and costs resulting in aesthetic, strong, long-lasting, functional and economical results.
We also have numerous long-term fabrication partners with whom we are able to exceed our annual capacity and accomplish large scale projects.
Our steel fabrication advantages can be summarized as;
▪ Capability to handle challenging projects
▪ Economical Solutions
▪ On-Time Delivery
▪ Fabrication and Services compliant to EU and International Standards
▪ Experienced Technical Team
▪ Wide range of Machinery and Equipment
▪ Result-oriented Approach
Our Steel Fabrication Process is certified with EN-1090 EXC3. This certificate enable us to put CE Mark on our steel components. As a result, our steel components can be safely used in every building within EU. EN-1090 Certificate also guarantees the quality of our fabrication. By applying all the requirements of this standard we are able to provide fault-free outcomes which enables a time-saving erection at site.
Another certificate we possess is ISO-3834-2 for Welding Quality Assurance. Vital stage of steel fabrication is welding. With an insufficient welding all the structure will be at risk. With the help of our team including Welding Engineers, Welding Technicians and certified welders we are able to keep our fabrication and quality processes sustainable.
In addition to this we are also controlling all of our material and service providers by means of EN-1090 requirements.
Our fabrications can be retrospectively investigated as traceability is another aspect we strictly apply.
We are continuously following the latest developments in steel processing and improving our machinery while we educate our staff to keep our quality at the highest level. We are able to guarantee the reliability, endurance and quality of our structures as the components fabricated by Proko are at least compatible to European standards and exceed these requirements in many occassions. We are capable of fabricating a wide range of light, medium and heavy steel structures including but not limited to; Handrails, Gratings, Stairs, Platforms, Doors, Cladding Supports, decorative accessories, etc.

Quality Control is handled as a continuous process starting from reception of enquiries, advancing with proper material procurement, strict inspections at fabrication, safe erection at site and finalized with preparation of the Comprehensive Quality File at the end of the project. As an obligation of a company possessing EN-1090 EXC3 and ISO 3834-2 Certificates, we are applying at least the Quality Control procedures set at these standards for every fabrication. 
In addition to our standard quality procedures, we are also creating custom ITPs (Inspection Test Plans) for each project depending on the Technical Specifications provided by the Client. Even if not requested by the Client we always prepare a basic Quality File for each project.
From the Material Acceptance to the loading of the truck all QC process is being managed, applied and recorded by Certified Inspectors and International/European Welding Engineers. We strictly require all Mill Certificates to be 3.1 according to the EN-10204 for all materials procured and all of our welders are certified according to EN ISO 9606-1. 
The coating activities are monitored, measured and controlled by certified inspectors. 
We also apply NDT (Non-destructive) tests or other required tests determined at the technical specification of the Project. 
Traceability of the fabrication is guaranteed with our comprehensive QC procedure. All documentation related to all fabrications is preserved for 10 years retrospectively. 
Proko Quality System is periodically audited by Internationally Accredited Certification Bodies.
