What are IS 2062 E250BR Plates?
IS 2062 E250BR is a specification set by the Bureau of Indian Standards (BIS) that outlines the properties of hot-rolled medium tensile structural steel. The “E250” indicates the minimum yield strength of 250 MPa, while “BR” stands for Better Resistance, particularly against atmospheric corrosion and wear, which is vital in outdoor applications.
These plates are primarily used in welded, bolted, and riveted structures, owing to their high weldability, ductility, and tensile strength.
Key Features of IS 2062 E250BR Plates
- Excellent weldability for easy fabrication
- High tensile strength and durability
- Good corrosion resistance especially in industrial and coastal environments
- Affordable and easily available in various thicknesses and dimensions
- Suitable for multiple environmental conditions including high-humidity zones
Top Applications of IS 2062 E250BR Plates in the Construction Industry
1. Structural Frameworks in Buildings
One of the most widespread uses of IS 2062 E250BR plates is in the load-bearing frameworks of residential and commercial buildings. These plates serve as the skeleton of high-rise buildings, warehouses, shopping malls, and apartment complexes.
Their high tensile strength ensures stability even under dynamic loads, making them ideal for earthquake-prone and wind-heavy regions.
2. Bridges and Flyovers
In bridge construction, the reliability of material is paramount. IS 2062 E250BR plates are frequently used in girders, piers, and trusses due to their strength, long service life, and resistance to environmental elements like moisture, salt, and temperature fluctuations.
Moreover, their corrosion resistance makes them perfect for coastal bridges or river crossings where materials are exposed to harsh conditions.
3. Industrial Structures and Sheds
Factories, warehouses, and workshops rely on heavy-duty structural components, and IS 2062 E250BR plates are perfect for manufacturing columns, beams, mezzanines, and roofing supports. Their robust nature ensures the structural integrity of buildings that house heavy machinery or storage loads.
4. Railway Infrastructure
IS 2062 E250BR plates are also widely used in railway construction, including railway platforms, foot-over bridges, and structural frames. Their ability to bear dynamic load cycles makes them suitable for components that undergo constant vibration and movement.
5. Offshore and Marine Construction
Thanks to their better resistance (BR) property, these plates are also used in offshore platforms, jetties, and port structures. Their corrosion-resistant properties provide durability in saline environments.
6. Power Plants and Energy Infrastructure
Power generation infrastructure demands sturdy, high-temperature-resistant materials. IS 2062 E250BR plates are used in building boiler support structures, transmission towers, and base frames for turbines and other heavy equipment.
7. Road Construction and Barriers
In road construction, IS 2062 E250BR steel plates are used to create guardrails, crash barriers, and dividers, where impact resistance and durability are critical for public safety.
8. Earthquake-Resistant Buildings
Due to their excellent ductility and load-distribution capabilities, IS 2062 E250BR plates are often used in regions where seismic activity is common. Structures built with these plates can better withstand lateral loads during earthquakes.
IS 2062 E250BR Mechanical Properties
Understanding the mechanical behavior of IS 2062 E250BR is crucial for deciding its application. These properties indicate how the material behaves under mechanical stresses.
| Mechanical Property | Value |
|---|---|
| Yield Strength (min) | 250 MPa (N/mm²) |
| Tensile Strength | 410 – 540 MPa |
| Elongation (%) | Minimum 23% (for 5.65√A gauge) |
| Impact Test Temperature | 0°C (Charpy V-Notch) |
| Test Requirement | BR (Better Resistance) |
The yield strength and elongation play a vital role in ensuring that structures can withstand not just static loads but also dynamic stress conditions like wind or seismic movement.
IS 2062 E250BR Chemical Composition
The chemical structure of a material affects its corrosion resistance, weldability, and strength. The balanced composition of IS 2062 E250BR makes it a versatile structural steel grade.
| Element | Composition (%) |
|---|---|
| Carbon (C) | Max 0.23 |
| Manganese (Mn) | 0.90 – 1.50 |
| Silicon (Si) | Max 0.40 |
| Sulphur (S) | Max 0.045 |
| Phosphorus (P) | Max 0.045 |
| Copper (Cu) | Max 0.20 (optional for corrosion resistance) |
The presence of low carbon content ensures better weldability, while controlled levels of manganese and silicon contribute to the steel’s toughness and ductility. Trace amounts of copper improve the material’s anti-corrosion properties.
IS 2062 E250BR Equivalent Material
For global sourcing or when comparing alternatives in international standards, it’s helpful to know the equivalent materials.
| Standard | Equivalent Grade |
|---|---|
| ASTM (USA) | ASTM A36 / A283 Gr.C |
| EN (Europe) | EN 10025 S275JR |
| JIS (Japan) | JIS G3101 SS400 |
| DIN (Germany) | St 44-2 / RSt 44-2 |
| Chinese Standard (GB) | Q235B |
Understanding IS 2062 E250BR equivalent materials helps in international projects where regional standards vary. It also eases procurement when substitutes are needed due to availability or budget constraints.
