Product Testing
Product Testing & Quality Assurance :-
The accent on quality commences with raw material selection and evaluation
for various end products by through testing of metallurgical and physical
properties. They are followed by strict quality checks at different stages
of production processes to ensure that the finished CR Steel Strips meet the
required specifications.
All finished products are tested for various quality parameters like
hardness, tensile strength, elongation, Erichsen value.
