Overview
About PanTMT CRS Sariya
CRS (Corrosion Resistant Steel) Sariya is a special type of TMT bar designed with anti-corrosive properties. Unlike normal TMT bars, it is manufactured by adding elements like Nickel (Ni), Copper (Cu) and Chromium (Cr) to enhance strength and durability.

Manufacturing & quality
How this bar is produced
Every PanTMT bar passes the same controlled route from raw material testing to bundling and dispatch.
Stage 1
Raw Material Yard
- Raw material receive
- Raw material composition testing
- Raw material uploading (quality wise)
Stage 2
Furnace
- Charging of raw material (standard scrap recipe)
- Composition testing (every 30 min.)
- Maintain standard temperature
Stage 3
Casting
- Checking of temperature and composition of molten metal
- Casting start
- Water quality check (every 6 hours)
Stage 4
Rolling Mill
- Rolling process start, passed from Thermex
- Checking mechanical properties of rolled material every 15 min.
- Check weight of rolled material
