Bars undergo several tests at various stages of production. During the process, series of samples are taken for testing in PMC’s own laboratory where the latest equipment and techniques are used to verify chemical and physical composition as well as mechanical properties. Test results are fed back to the plant immediately for any adjustments required.
Final quality check is conducted before dispatching to customers and necessary test certificates are issued as a testimony to meet customers’ quality requirements.
