MS Angle

MS Angle

MS Angle, also known as Mild Steel Angle, is a type of structural steel product shaped in the form of an “L”, which gives it the alternate name L-angle. It is one of the most commonly used steel shapes in construction, fabrication, and structural applications due to its versatility, strength, and cost-effectiveness.


1. Composition and Properties

MS Angle is made from mild steel, which is a low-carbon steel with carbon content typically ranging from 0.15% to 0.25%. This composition gives mild steel the following properties:

  • Good weldability

  • High ductility

  • Moderate strength

  • Good machinability

  • Relatively low cost

These properties make MS Angles suitable for both load-bearing and non-load-bearing applications.


2. Structural Form

MS Angles are characterized by their L-shaped cross-section, which includes:

  • Two legs that meet at a 90-degree angle.

  • Equal angle: both legs are of the same length (e.g., 50×50 mm).

  • Unequal angle: one leg is longer than the other (e.g., 75×50 mm).

They are available in various sizes and thicknesses, depending on the structural requirements. Common thicknesses range from 3 mm to 10 mm or more, and they are generally supplied in standard lengths (usually 6 or 12 meters), though custom sizes can be made.


3. Manufacturing Process

MS Angles are typically manufactured using the hot rolling process, where steel billets are heated and passed through rollers to shape them into angles. This process ensures:

  • Uniform thickness

  • Consistent mechanical properties

  • Good surface finish


4. Applications

MS Angles are used in a wide range of industries and structures due to their adaptability:

  • Construction Industry:

    • Structural frameworks

    • Roofing and trusses

    • Support beams

    • Bridges and towers

  • Fabrication Works:

    • Machinery frames

    • Shelving and racking systems

    • Guard rails and fencing

  • Infrastructure Projects:

    • Railway and highway barriers

    • Communication towers

    • Transmission line supports

  • Automotive and Shipbuilding

    • Chassis and structural components


5. Advantages

  • Cost-effective compared to other metals

  • Ease of fabrication (cutting, drilling, welding)

  • Readily available in the market

  • Durable and strong

  • Can be galvanized or painted for corrosion resistance

Conclusion

MS Angles are a vital component in the construction and manufacturing sectors due to their robust structure, flexibility in usage, and economical nature. Whether used as a primary structural member or as support for other frameworks, they play a crucial role in ensuring the strength and stability of a wide variety of structures and products.
