02The company standard
More than steel.
Certainty in every rib.
Stena Steel brings manufacturing discipline and practical project support together.
Every bar begins with controlled material preparation and continues through rolling, thermo-mechanical treatment, dimensional review and final release. The result is reinforcement steel made to be consistent in the yard, predictable during fabrication and dependable inside the structure.
01Strength you can specifyFe 500, Fe 550 and Fe 600 classes for different structural demands.
02Ductility you can build withMaterial behaviour suited to bending, fabrication and resilient RCC design.
03Traceability you can followBatch-led quality checks and clearer communication through dispatch.
03The product range
The right grade
for every ambition.
Seven yield classes for residential, commercial, industrial and infrastructure reinforcement — plus a corrosion-resistant chemistry.
01 / Everyday RCC
IS 1786
Stena Fe
500
The default choice for most Indian reinforced concrete. Balances strength against bending and fabrication behaviour, which keeps it easy to work with on site.
- Yield strength500 N/mm²
- Elongation12%
- Tensile / yield1.08

02 / Ductile detailing
IS 1786
Stena Fe
500D
Same 500 N/mm² yield as Fe 500, but the D specification demands markedly higher elongation and tighter sulphur and phosphorus limits — so the bar deforms further before it fails.
- Yield strength500 N/mm²
- Elongation16%
- Tensile / yield1.10

03 / Seismic grade
IS 1786
Stena Fe
500S
The S specification is written for seismic design. It asks for the highest elongation in the 500 class and a tensile-to-yield ratio of at least 1.25, so the bar keeps taking load well past first yield.
- Yield strength500 N/mm²
- Elongation18%
- Tensile / yield1.25

04 / Higher load
IS 1786
Stena Fe
550
Ten percent more yield strength than Fe 500, which lets the designer carry the same load with less steel where the ductility demand is lower.
- Yield strength550 N/mm²
- Elongation10%
- Tensile / yield1.06

05 / Strength with ductility
IS 1786
Stena Fe
550D
The combination most high-rise work asks for: the 550 yield class, but with elongation and chemistry limits close to the D-grade discipline of Fe 500D.
- Yield strength550 N/mm²
- Elongation14.5%
- Tensile / yield1.08

06 / Top of IS 1786
IS 1786
Stena Fe
600
The highest grade the Indian Standard covers. Its value is congestion relief — fewer or thinner bars in heavily reinforced members, so concrete can actually be placed and compacted around them.
- Yield strength600 N/mm²
- Elongation10%
- Tensile / yield1.06

07 / Beyond the standard
To order
Stena Fe
650
For designs that call for yield strength above the Fe 600 ceiling. IS 1786:2008 does not cover a 650 class, so this is rolled and released against a specification agreed in writing for the order.
- Yield strength650 N/mm²
- ElongationBy agreement
- Tensile / yieldBy agreement
Not an IS 1786:2008 grade — properties are fixed per order and must be approved by your structural engineer.
