Are angle steel and angle iron the same?

Release time:

2024-03-14

Although angle steel and angle iron are similar in appearance, they differ in what they are made of, what they are used for, and in some cases what they are called. Therefore, in professional or formal situations, it is important to clearly distinguish between the two terms.

Angle steel and angle iron are not exactly the same.

Although angle steel and angle iron are similar in appearance and specifications, both are long strips of steel with two sides perpendicular to each other, they are different in materials, uses, and in some cases, names. Specifically:

Materials and uses:

Angle steel usually refers to an angle profile made of steel materials, which is divided into equilateral angle steel and unequal angle steel. The two sides of the equilateral angle steel are equal in width. The specifications of the angle steel are expressed in millimeters of side width × side width × side thickness, such as "∟30×30×3", which means an equilateral angle steel with a side width of 30 mm and a side thickness of 3 mm.
Angle iron may be used as a synonym for angle steel in daily life and in some situations, but they may be different in material. Angle iron is mainly processed from ordinary carbon structural steel and has good toughness and ductility.
use:

Angle steel is widely used in construction and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.
Angle iron is mainly used in engineering structures such as supports and bridges in the construction and machinery fields.
call:

In some cases, the terms angle iron and angle steel may be used interchangeably, especially in non-professional settings or in daily communication. For example, Q235 angle steel is also commonly known as angle iron in some occasions.

In summary, although angle steel and angle iron are similar in appearance, they differ in material, purpose, and in some cases, what they are called. Therefore, in professional or formal situations, it is important to clearly distinguish between the two terms.

The difference between steel coils and steel strips

The main difference between steel coils and steel strips is their width and range of applications. Coil generally refers to a larger width coil of steel, while steel strip refers to a smaller width coil of steel, with narrower widths and more specific application requirements.

What are the three ways of connecting steel bars?

The connection is made by melting parts of the steel bars and then cooling and solidifying into a whole. There are two types of welding methods: pressure welding and fusion welding. Pressure welding includes flash butt welding, resistance spot welding, and air pressure welding; fusion welding includes arc welding and electroslag pressure welding. Welded connection joints are strong and fast, and are suitable for lengthening longitudinal steel bars and connecting steel bars to steel plates.
