Our team of highly motivated Quality Control Engineers, Metallurgists and Chemists strive continuously to meet the demands of our global customers.

Quality is a fundamental part of our business philosophy, which says ‘if minute details are taken care of during the process, the end-product will take care of itself’. This dedication is reflected in the high quality of every product which comes out from the factory. As a result, our customers can rely on a product of undisputable quality, reliability, dependability and durability.

Our Quality and Inspection department is fully equipped with the following testing equipment, which are regularly calibrated.

Excellence is never an accident,

It is an act of deliberate design .”
