Then these projects are realised using the latest technology machinery used by the company’s expert welders  whose skills and expertise have been certified by international institutions.  
After this, the product goes through number of tests by its technicians with modern devices which are inspected and calibrated by international institutions. Finally, the surface of the tank is sand blasted according to standards and covered with special protective paints to endure sun, wind, cold and other effects.
Isisan, together with its employees, guarantees to become the symbol of continuity and respectability while providing products with universal standards without compromising its human-centred approach.
