Laboratory

We at PAKSTEEL, strictly adhere to the ASTM and BSI international standards. Our QC section samples each lot/batch and inspects the quality at various levels of production. This department then performs tests using specified accepted testing methods, these are routinely conducted within the premises to facilitate the customer and improve/monitor product quality regularly.The perfection of our work has captured the sharp eyes of descending clients in the public and private sectors, including some of the top multi-national construction firms. To produce high quality steel according to the required specification, we at PAKSTEEL are equipped with both chemical and physical laboratories at our factories.
