Steel angle. Types, Characteristics, Applications

What is a steel angle?

A steel angle is a profile section with a L-shaped cross-section, used for creating load-bearing structures, reinforcing frames, and as connecting elements in construction and mechanical engineering.

The production of angles is regulated by the EN 10204 standard, which defines dimensions, weight, manufacturing accuracy, and permissible deviations. Angles are produced as equal-leg and unequal-leg, allowing their use in a wide variety of projects. Depending on their purpose, angles can be hot-rolled or bent. This choice depends on the tasks requiring either high strength or ease of installation.

Main characteristics of metal angles

Metal angles have a wide range of sizes and characteristics, making them versatile in application. The main parameters include:

• Dimensions: Shelf height from 20 to 200 mm, Wall thickness from 3 to 12 mm.
• Materials: S3 (carbon steel) for standard tasks, S355(low-alloy steel) for work in aggressive environments, 40Cr (alloy steel) for high loads.
• Manufacturing methods: Hot rolling and bending from steel sheet.
• Surface: Can be treated (galvanizing, powder coating) or untreated.
• Weight: Depends on the dimensions and steel grade.

Thanks to these parameters, metal angles are suitable for most structural and decorative tasks.

Types of metal angles

1. Hot-rolled angles

   These angles are produced by hot rolling and are used for heavy load-bearing structures. Due to their high strength and load resistance, hot-rolled angles are used in the construction of bridges, buildings, and other large objects.

2. Bent angles

   Manufactured by bending steel sheets, making them less strong but more versatile in installation. Such angles are used for decorative and lightweight structures.

3. Equal-leg and unequal-leg angles

   Equal-leg angles have the same shelf width and are suitable for even load distribution, while unequal-leg angles are used to reinforce individual structural elements.

Applications of metal angles

Metal angles are used in various industries due to their strength, versatility, and wide range of sizes. Here are the key areas:

1. Construction

   Used for creating building frames, strengthening concrete structures, and installing lintels. A hot-rolled 125x125x8 angle is ideal for load-bearing structures and supports. Such products are capable of withstanding significant loads and serve as the basis for durable metal frames. Hot-rolled angles made of carbon steel, such as the 50x50x3 angle, are suitable for lightweight structures, while large equal-leg angles are used for reinforcement.

2. Mechanical engineering

   Angles are used in the production of frames, chassis, connecting elements, and components of mechanisms. For such tasks, the 80x80x6 angle is often used, which has optimal parameters for fastening parts.

3. Interior and decor

   For the manufacture of decorative elements, railings, and furniture frames, a bent angle with a galvanized or painted surface is excellent. It is easy to install and guarantees the reliability of structures for a long time.
