Steel billets

The Billets Produced By the Company Can Be Broadly Divided Into Three Main Types I.e.
1. M.s. Billets
2. Crs Billets
3. Special Alloy Billets
m.s. Billets are Used for Rolling of Tmt Re-bars of Fe415 and Fe500 Grade and Various other Structural Steel Products.
crs Billets are Used Fro Rolling of Crs Tmt Re-bars.
special Alloy Billets are Used for Rolling of Any Special Grade Tmt Re-bars like Earthquake Resistant Tmt Re-bars and for Special Grade Structural Steel Products.
the Following are the Sizes of Billets Available with Shyam Steel Industries Ltd.:
* 100 X 100
* 125 X 125
* 150 X 150
