“Quality Assurance aims
how to address quality related errors and
how to improve those errors before occurring.
The plan helps in eliminating defects.”
RAHUL GROUP carries a Quality Management System certified in accordance with the ISO 9001:2008 standard. The well-deserved certification is the result of high and consistent standards of processes, which is reflected in the high quality of the products.
An independent Quality Assurance department is responsible for work procedures required to ensure that manufacturing processes are carried out in accordance with international technical delivery conditions given in ASTM, ASME, EN, IS and other International Specs along with the customer specifications.
To guarantee high quality, we procures raw material from top-notch vendors of international repute. The manufacturing is carried out under strict process control and monitored throughout the production process to ensure total conformity to requisite specifications.
All through the Manufacturing process and before dispatch, uncompromising and stringent tests are carried out as per the standards specifications and/or customer specific requirements. Every single piece of material is subjected to a thorough visual inspection by trained Engineers to detect dimensional inaccuracies, surface imperfections and other quality imperfections.
To ensure complete identification and traceability even after supplies are effected, all the information as required by the standards, i.e. Logo, Brand name, size, grade, specifications, heat number is marked on all the Products.
We ask our Customer to give the feedback and helps in improving the business process.
