Ss400 S235jr S355jr Equal/Unequal Carbon Steel Angle

Carbon steel section -Tue-03-2025

The steel angle is a carbon structural steel for construction. It is section steel with a simple cross-section. It is mainly used for metal components and the frame of the workshop. It is required to have good weldability, plastic deformation performance and certain mechanical strength in use. The raw steel billet for the production of angle steel is a low-carbon square billet, and the finished angle steel is delivered in the form of normalized or hot rolled.

Steel angle bar can be made into pressure structural bracket based on different size and grade, and also can be made into connector between structural beam. Widely used for various building structures and engineering structures, such as house beams, bridges, power transmission towers, lifting, and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench brackets, power piping, busbar bracket installation, and warehouse shelves.

Equal and unequal are the two major types of steel angle:

Steel angles are fashioned using a single flat steel section and bending it, generally at a 90-degree angle with both legs the same size. See below for a rundown of the different steel angle types:

Equal angle

Equal steel angles have 2 axes’ that are the same length, hence their name. They are the most common types of steel section and can be made to various specs and cut to any size, making them extremely versatile. Their sizing is represented by side A x side B x thickness.

Unequal angle

Unequal steel angles are also right-angled; however, they have different sized axis’ making them L-shaped. This section is much stronger (up to 20%) with a much higher strength to weight ratios. Their sizing is represented by side A x side B x thickness.

Steel Angle bar(iron angle), hot rolled from the heating boiler and shaped with vertical angle 90 degree and normally length in 6m/ 9m/12m.

According to shape difference, we distiguish mild steel angle bar from equal and unequal. Equal angle has same width and specification in width A * width B * thickness. For example: 50*50*4mm, means width A is 50mm, width B is 50mm, and thcikness is 4mm. We also always named specification 4#(No.4). Hot rolled equal angle size from 2# to 200#. Unequal angle has different width and specification in width A* width B* thickness. For example: 75*50*6mm, means width A is 75mm, width B is 50mm and thcikness is 6mm.

Application

Galvanized Angle Bar is mainly used to make frame structures, such as high-voltage transmission tower, the frame on both sides of the main beam of steel bridge,the column and arm of tower crane on construction site, the column and beam of workshop, etc. The Angle steel can be composed of different stress members according to the different needs of the structure,and can also be used as a connector between members. Widely used in all kinds of building structures and engineering structures,such as beams, Bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reactor, container racks and warehouses.
