IS 2062 E250 Structural Steel: Weight, Properties and Applications

IS 2062 E250 is the go-to structural steel grade in India — it covers everything from rolled plates and flat bars to beams, channels, and angles used in buildings, bridges, conveyor structures, and industrial frames. Understanding its properties, density, and weight calculation is essential for any engineer or procurement team working with Indian structural steel.

What IS 2062 Covers

IS 2062:2011 specifies requirements for hot rolled medium and high tensile structural steel in the form of plates, strips, shapes (beams, channels, angles), and flats. It covers six strength grades: E250, E300, E350, E410, E450, and E550. The "E" prefix stands for elastic limit (yield strength), and the number gives the minimum yield strength in MPa.

E250 is the lowest-strength grade in the standard and, because of its wide availability, lower cost, and easy weldability, it accounts for the majority of structural steel consumed in India. You will find it in every steel service centre, from SAIL's plants in Bhilai and Bokaro to JSW Steel's Vijayanagar mill.

IS 2062 E250 Mechanical Properties

The table below lists the key mechanical properties of IS 2062 E250 per IS 2062:2011. Properties vary slightly with section thickness — thicker sections have slightly lower yield strength because of slower cooling during rolling.

Density and Weight Calculation for IS 2062 E250

IS 2062 E250 is mild steel. Its density is 7.85 g/cm³ (7,850 kg/m³) — the same standard value used for all mild and low-alloy structural steels. IS 2062 ka weight kaise nikalte hain? The formula depends on the section type:

For plates and flat bars: Weight (kg) = Length (m) × Width (m) × Thickness (m) × 7,850

For round bars: Weight (kg/m) = (Diameter²) / 162

For hollow sections: Weight (kg/m) = 2 × (h + w − 2t) × t × 7.85 / 1,000

Worked Example: 10mm IS 2062 E250 Plate and ISMC 200 Channel

Example 1 — Plate: A mezzanine floor uses 10mm IS 2062 E250 plate, 2000mm × 1000mm.

Weight = 2.0m × 1.0m × 0.010m × 7,850 = 157 kg

Example 2 — Rolled section: An ISMC 200 channel per IS 808 weighs 22.1 kg/m. A 6-metre length weighs:

Weight = 22.1 × 6 = 132.6 kg

ISMC 200 is one of the most common sections used in mezzanine structures, equipment platforms, and small crane girders across India. Tata Steel produces it to IS 2062 E250 as standard, and the 22.1 kg/m value is taken directly from IS 808 — the Indian Standard for hot rolled steel sections.

Common Applications of IS 2062 E250

E250 is the workhorse grade for light to medium structural applications. You will see it in mezzanine floors, equipment support frames, conveyor structures, pipe supports, site office structures, and general fabrication where loads are static and the design is not governed by fatigue or impact.

For crane girders and moving equipment supports, E250B (with 27J impact at 0°C) is specified because the dynamic loading raises the risk of brittle fracture at stress concentrations. For most Indian climates, −20°C service is not a concern, so E250C rarely appears in standard structural projects.

When to Upgrade from E250 to E350

E350 has a yield strength of 350 MPa — 40% higher than E250. The practical implication is that you can use lighter sections (smaller depth, thinner flanges) and still carry the same load. This reduces steel tonnage by 15–25% on weight-governed designs, which offsets the higher per-tonne price of E350.

JSW Steel produces IS 2062 E350 plates and sections on request; Tata Steel supplies E350 through their Tata Structura and standard section ranges. The price premium over E250 is typically ₹2,000–3,500 per tonne, which is justified when the section size reduction saves more in fabrication, transport, and foundation cost.

For export-facing projects, IS 2062 E250 is broadly comparable to ASTM A36 (yield 250 MPa, UTS 400–550 MPa) — the two standards are nearly equivalent for plate and section applications, though chemical composition limits and testing requirements differ slightly.

Where to Source IS 2062 E250 in India

The primary producers of IS 2062 E250 in India are JSW Steel (plates and sections from Vijayanagar and Dolvi), Tata Steel (plates from Jamshedpur, sections and structurals from various mills), and SAIL (plates from Rourkela and Bokaro, sections from Bhilai). All three supply material with mill test certificates (MTC) that quote the heat number, chemical analysis, and mechanical test results against IS 2062:2011.

When ordering from a service centre, always ask for the MTC and verify that the certificate explicitly states IS 2062:2011 and the grade (E250A, E250B, or E250C). Generic "MS plate" without a grade designation may not meet IS 2062 — this matters when a third-party inspection agency is checking your material on a project.
