Since its establishment, it has guided the group's development in a strategic and well-planned manner through a scientific and multidimensional management approach.The holding's organizational diversity and scope of activities are extensive. Its industrial outputs include various steel billets, rebar (plain, ribbed, and coil), steel sections (I-beams, channels, and angles), mineral products (hematite and magnetite iron ore, titanium concentrate, high-purity limestone and silica, coal, copper, and gold ores), metal structures, overhead cranes, various steel and galvanized pipes (for gas, industrial, and water supply), square and rectangular tubes (industrial and construction), and galvanized sheets.In recent years, the holding's strategy has focused on building and transferring production facilities through either cash or financing. This approach has accelerated industrial development, increased employment opportunities in the region, and created an environment for specialized investment by producers as well as public participation in projects.16:T454, The inspections carried out include the following:A- Raw Material Inspection: Includes visual condition control, dimensions, labels and manufacturer certificates, and analysis of steel sheets and billets.B- In-Process Inspection:1- Visual Inspection2- Dimensional Control3- Hydrostatic Test4- Drift Expanding Test5- Flattening Test6- Bending & Rebending Test7- Inspection of galvanized coating by destructive and non-destructive methods8- Weight ControlC- Laboratory Tests:1- Determination of mechanical properties of rebar and steel sheet using a universal testing machine2- Control of acid, flux, and degreasing tanks in pipe and sheet galvanizing lines3- Daily monitoring of cutting fluid in pipe and profile linesD- Final product inspection before leaving the factory for delivery to the customer
