Saranalume Specification


BASE METAL SPECIFICATION

One important thing to produce high quality pruduct which compliance with national and international standard is raw materials quality. The main raw material for Saranalume is cold rolled steel which know as CRC.
PT Saranacentral Bajatama always looking for cold rolled steel which compliance with SNI and AS 1397. To ensure the consistency of best raw material quality, PT Saranacentral Bajatama always chose vendor with national and internatinal good reputation.

The following standard materials used :
