With a focus on construction and structural engineering, it is obvious that there are certain materials that are best for strength, versatility, and durability. Among these materials is mild steel angle, popularly known and widely used in different building industries as an essential steel product used in various structures, machinery, and frames. In this blog, we will discuss every essential detail about mild steel angles, their types, applications, and the industries where they find application, with some emphasis on popular steel suppliers and manufacturing steel companies that make and supply these materials.

What is a mild steel angle?

As its name suggests, a mild steel angle is a metal angle, commonly known as an MS angle. It has an L-shaped sectional cut. High-strength, highly corrosive-resistant, and economical, these angles have become a prominent type of application in various construction works. Typical uses of MS include structural reinforcement in transmission towers, bridges, and, as in all such constructions, framing and shelving.

The steel angle usually forms a 90-degree angle with equal and unequal sides. When both sides are of equal length and thickness, it's called an equal angle, while when one side is bigger than the other, it is an unequal angle. They are adaptable, general-purpose steel raw material products; in cutting, drilling, or welding, appropriate requirements of the specific construction become fulfilled.

Types of Mild Steel Angles

There are many types of MS angles, but the most common are equal angles and unequal angles. However, there are others: 

  • T Shape Angles—these types are most generally used in engineering and fabrication activities. 
  • • V-shape angles are best suited for their mechanical strength properties as well as durability. 
  • Indian Standard Bulb Angles—they are particularly one such special type because the end of an angle's leg is shaped like a small bulb that provides it with extra strength and stability. 

Each of the types can further be divided into different grades, sizes, and finishes, depending on the required construction specification.

Applications of Mild Steel Angles

It is the remarkable strength, flexibility, and ease of fabrication that makes mild steel angle one of the versatile materials that find applications in different industries. The following are a few off-the-shelf applications:

1. Construction Industry

MS angles find great application in erecting infrastructures such as different types of buildings, i.e., residential and commercial, bridges, etc., making provision of structural frames, supports, and reinforcements, besides giving stability and strength.

2. Machinery and Equipment

MS angle iron is used in the machinery industry to form frames, brackets, and supports for machines. Its malleability and weldability make it suitable for forming ad-hoc components.

3. Automobile Sector

Manufacturers use MS angle sheets for creating frames, chassis, and other supporting structures for their vehicles. Because of its durability and adaptability, mild steel angles are included in the making of automobiles. 

4. Warehousing Industry

Progressed and heavy MS angle iron made it the most unimaginable and most-used consumable element for the purpose of constructing shelves, racks, and all types of structures used in operation in warehousing and storage. 

5. Other Applications

MS angles are also extensively used in constructing transmission towers, communication towers, scaffolding, and agricultural equipment. It could be termed as a highly versatile material and can be used in almost all forms of fabrication and engineering work.

Types of Steel Angles and Steel Angle Sizes

Understanding different steel angle sizes is very important while selecting a perfect mild steel angle for your work. Some of the usually available sizes are: 

- 25 x 25 x 3 mm 

- 35 x 35 x 4 mm 

- 50 x 50 x 5 mm

- 90 x 90 x 6 mm 

- 100 x 100 x 8 mm 

- 130 x 130 x 12 mm

Steel angles can be available in several different grades and finishes, such as black (untreated), hot-dip galvanized, and painted, based on various applications. 

Calculating the Weight of Mild Steel Angles

One of the most frequently asked questions when dealing with MS angles is how to know their weight. MS angle weight is usually measured in kilograms per meter or kilograms per foot. To calculate the weight, the following must be done: 

  1. Determine the width (W) and thickness (T) of the angle.
  2. Calculate the cross-sectional area (A) using the formula: A = (W - T) x T.
  3. Multiply the area by the density of steel (K) to obtain the unit weight per meter: UW = A x K.

Otherwise, several online calculators help you determine the weight of mild steel angles quickly by feeding the specification.

Advantages of Mild Steel Angles

There are a variety of advantages that mild steel angles render to the construction and fabrication industries:

1. Ratio of strength to weight

Mild steel angles have high strengths; hence, they are better placed under heavy structural loads. The steel angle provides strong frameworks that are not heavy.

2. Malleability and adaptability

Due to its low carbon content, mild steel makes weldable, drillable, and workable angles for maximum application versatility. With this quality of malleability, customized adaptation for specific projects is also easy.

3. Cost-Efficiency

As compared to other available compositions, mild steel angles are relatively inexpensive so that they do not make any devil out of a construction budget. Thus, it is a preferred option of many steel sellers and construction companies.

4. Recyclability 

Because MS angles are highly recyclable, they can also be considered an environmentally friendly material for construction and manufacturing. It is cheaper to use MS angle iron, as it can be recycled, too. It supports sustainable practices during construction.

Conclusion

Mild steel angles are an integral part of construction and engineering. They are strong, they are malleable, and they are versatile—the compounds on which most structural supports are based, framing and reinforcement of all types. Whether working on a home, a bridge, or an industrial machine, nothing compares to the strength and economy that MS angles provide.

Mild steel angle iron and the protection of your project cannot be divorced from reliable steel source steel suppliers and steel companies. The right MS angle can generally be the key point to having greater stability and longer life for your construction while controlling costs.
