as per the policy of company to assure the highest level of quality to our customers, our Quality Assurance Department has developed a Quality Management System (QMS) which makes sure that regular quality tests are performed at each level of value addition. Our QMS is designed in such a way that if any flaw is found in any batch of production, it is instantly logged out of the process and disposes off so as to avoid any complaints from our prestigious customers. From raw scrap to production of billets and then till final dispatch of Deformed Steel Bars we make sure that all quality measures are taken and the products manufactured are strictly as per the specifications of their respective ASTM Standards.
Our laboratory consists of following testing equipments:
Spectrometer
Tensile Machine
Oxygen Analyzer
100 Tone Universal Testing Machine
Hardness Tester
Impact Tester
Magana Flux Flaw Detector
Shore Hardness Tester
Ultrasonic Flaw Detector Metallurgical Microscope with Camera Attachment
Abrasive Cut Off Machine
Billet Cut off for Quick Macro Analysis
Highly Sophisticated Emission Spectrometer Spectro Lab.
A tensile machine has been installed at our sales point for maximum satisfaction of customers. Tension test report of each product is provided to customers along with the product if demanded.
