Metals and Metallography
The Company has complete in house facility to execute various jobs related to metals related products
Metals & Alloys are the integral parts of Infrastructure & Industrial growth. Without Analysis cannot be possible to achieve the good quality of Metal & Alloys. DTH plays a vital role and certifying all types of components of metal & alloys by various methods Chemical, Mechanical non destructive testing by well qualified scientists & technique with best quality of Instrument.
From fragile wire to structural components, metal producers are faced with a host of testing challenges. Manufacturers of metal products must meet advertised strength and performance ratings DTH are the total solution provider for METAL PRODUCTS testing.
