MS ANGLES
TYPES OF STEEL ANGLES
According to ‘ISI Handbook for Structural Engineers’ rolled steel angle sections are classified as:
Indian Standard equal angles – Equal angles are steel angles that feature legs with equal length and thickness.
Indian Standard unequal angles – Unequal angles are steel angles with legs that feature unequal length but equal thickness

Key Takeaway
Uses of steel angles
Frames
Due to its ductility and high-strength, steel angles are an excellent resource for making frames. Angle framing is used to support interior mouldings, cladding, handrails, trimmings, utility carts, paneling, etc.
Bridges
Steel angles are widely used in the construction of bridges. Angles provide reinforcement to concrete which reduces material handling for builders. These are used in bridge components like bearings, arches, or girders.
Machinery and appliances
Since angles form an excellent material for structural support, industrial machinery and even household appliances use steel angles for reinforcement. To give their unique shape more structural integrity corners of appliances like washing machines, industrial ovens, stoves, etc., are fitted with steel angles.
FAQ of Mild Steel Angle:
Q. What is the
difference between mild steel angles and stainless steel angles?
A. MS angles are made from low-carbon
steel, while stainless steel angles are made from an alloy that contains a
significant amount of chromium. Stainless steel angles offer better corrosion
resistance than mild steel angles and are often used in applications where
corrosion is a concern. However, stainless steel angles are generally more
expensive than mild steel angles.
Q. How do I
select the right size of mild steel angle for my project?
A. The size of the mild steel angle you
need depends on the specific requirements of your project. Consider factors
such as the load-bearing capacity, structural stability, and the dimensions of
the structure you’re working on. Consulting with a structural engineer or
referring to engineering design standards can help you determine the
appropriate size and dimensions.
Q. Can mild
steel angles be welded?
A. Yes, ms angles can be welded using
various welding techniques such as arc welding, MIG welding, or TIG welding.
Mild steel is generally considered to be easily weldable, making it convenient
for fabrication and joining structural elements.
Q. How can I
protect mild steel angles from rust and corrosion?
A. Mild steel is prone to rust and
corrosion, but there are several methods to protect it. The most common methods
are galvanizing and painting. Galvanizing involves applying a zinc coating to
the mild steel angles, which provides excellent corrosion resistance. Painting
the angles with a suitable primer and topcoat can also protect them from
corrosion.
Q. Where can I
purchase mild steel angles?
A. Mild steel angles are commonly
available at steel suppliers, metal fabrication shops, and construction
material stores. You can also explore online platforms and industrial supply
websites to find a wide range of options and sizes.
Q. What are
some typical applications of mild steel angles?
A. MS angles have a wide range of
applications. They are commonly used in construction for structural supports,
framework, and bracing. They are also used in manufacturing and fabrication for
making racks, shelves, frames, and various metal structures. Additionally, mild
steel angles find applications in industries such as automotive, machinery, and
equipment manufacturing.
Q. Are there
any limitations to using mild steel angles?
A. MS angles have excellent strength and versatility, but they may not be suitable for applications where high levels of corrosion resistance or extreme temperatures are required. In such cases, alternative materials like stainless steel or specialized alloys may be more appropriate.
