# Equilateral angle steel

EN 10025-2 is European standard, EN 10025-2 Carbon Steel is a steel alloy where carbon is the main alloying element.

Carbon steel can be grouped into 3 categories: Low Carbon Steel (also known as Mild Steel), Medium Carbon Steel and High Carbon Steel.

Angle steel Commonly known as angle iron , is a long strip of steel whose two sides are perpendicular to each other and form an angle. There are equal angle steel and unequal angle steel. The two sides of the equilateral angle steel are equal in width. Its specification is based on the side width × Edge width × The edge thickness is expressed in millimeters. Such as \"∟ 30 × thirty × 3 \", i.e. equal angle steel with side width of 30mm and side thickness of 3mm. It can also be expressed by model, which is the centimeter of the side width, such as ∟ 3\\. The model does not indicate the dimensions of different edge thicknesses in the same model. Therefore, the edge width and edge thickness dimensions of angle steel shall be filled in completely in the contract and other documents to avoid using the model alone. The specification of hot-rolled equilateral angle steel is 2\\20\\. Angle steel can form various load-bearing members according to different structural needs, and can also be used as a connector between members. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses.

Theoretical weight calculation of equilateral angle steel The theoretical weight of steel is calculated in kilogram (kg). It is: w (weight, kg) = f (sectional area mm ² )× L (length, m) ×ρ (density, g/cm ³)× Density of 1/1000 steel: 7.85g/cm ³

Angle steel can form various load-bearing members according to different structural needs, and can also be used as a connector between members. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, warehouse shelves, etc.

Angle steel is a kind of carbon structural steel for construction. It is a simple section steel. It is mainly used for metal components and plant frames. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The raw steel billet for angle steel production is low-carbon square steel billet, and the finished angle steel is delivered in hot rolling forming, normalizing or hot rolling status.

Classification of angle steel
Mainly divided into Equilateral angle steel and Unequal angle steel The unequal angle steel can be divided into unequal edge equal thickness and unequal edge unequal thickness.
