Quality assurance
Quality is the most emphasized verse in the ethic book of Vinayak where maintaining quality parameters is not just a process, but a practice, instilled at every stage of the work.
Each Vinayak TMT bar passes through stringent quality checks adhering to BIS and other international standards. A flawless system is in place that ensures that each and every component, right from raw material to finished product is tested before being used or dispatched.
