there are two main types of angle bars: Equal Angle Bars and Unequal Angle Bars.
Both types of angle bars are manufactured in various sizes, thicknesses, and materials to meet specific project requirements. They are typically made from steel and can be galvanized for increased corrosion resistance. The choice between equal and unequal angle bars depends on the structural design and load distribution requirements of the specific application.
Specification representation method for angle steel
The specification of angle steel is expressed by the size of side length and side thickness. The specifications of domestic angle steel are 2-20, and the number of centimeters of side length is the number of numbers. The same number of angle steel often has 2-7 different side thicknesses. The imported angle steel indicates the actual size and edge thickness on both sides and indicates the relevant standards. Generally, the large angle steel with a side length of more than 12.5cm, the medium angle steel between 12.5cm-5cm, and the small angle steel below 5cm.
The order of import and export angle steel is generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade. In addition to the specification of angle steel, there is no specific composition and performance series.
The delivery length of angle steel is divided into fixed length and double length. The selection range of fixed length of domestic angle steel is 3 – 9m, 4 – 12m, 4 – 19m and 6 – 19m according to different specifications. The length range of angle steel produced in Japan is 6 – 15m.
The section height of unequal angle steel is calculated according to the long side width of unequal angle steel. It refers to the steel with an angular section and unequal lengths on both sides. It is a kind of angle steel. Its side length is from 25mm × 16mm-200mm × 125mm. It is rolled by hot rolling mill. The general specification of non-equilateral angle steel is : 50 * 32 – 200 * 125, the thickness is 4-18mm.
Equal angle bars represent a broad product line of bar-shaped building elements. They do have parallel legs and their tolerances are defined by ASTM A 484, the laser fused execution has additionally the product standard defined by ASTM A. The MTC (material test certificate) is 3.1 according to EN .

Hot rolling process refers to a processing method where metal billets are heated to a certain temperature and continuously rolled through a rolling mill to obtain the required specifications and shapes of metal materials. For the hot rolling process of angle steel, it mainly includes three steps: heating, rolling, and cooling.
The first stage is the heating stage. The heating temperature of angle steel is one of the important factors affecting the rolling quality. Low heating temperature can lead to a decrease in metal plasticity, which can easily cause cracks during rolling; Excessive heating temperature can easily cause grain growth and affect the mechanical properties of the material. Therefore, the selection of heating temperature needs to be determined based on the specific material’s organizational structure and performance requirements.
Next is the rolling stage. The rolling process of angle steel usually adopts multiple passes of rolling to ensure the accuracy and surface quality of the final product. Firstly, the heated angle steel billet is fed into the blooming area of the rolling mill for blooming, with the aim of reducing the cross-sectional size and improving the internal structure; Then, gradually obtain the required cross-sectional shape and size through rolling through intermediate and finishing passes; Finally, after rolling in the final rolling zone, the surface of the angle steel is improved in terms of smoothness and dimensional accuracy.
Finally, there is the cooling stage. The cooling process of angle steel is mainly achieved through air cooling and water cooling. The purpose of cooling is to rapidly cool the angle steel billet, refine its grain size, and eliminate internal stress. During the cooling process, it is necessary to control the cooling rate reasonably based on the material and specifications of the angle steel to avoid excessive hardening or cracking.
In the hot rolling process of angle steel, there are still some key parameters that need to be noted. For example, the rolling force and speed during the rolling process are important factors that affect the deformation and internal structure of angle steel. Reasonable selection of rolling force and rolling speed can ensure the surface quality and mechanical properties of angle steel. In addition, it is also necessary to pay attention to factors such as rolling temperature, cooling method, and selection of rolling rollers to ensure the quality and performance of angle steel.
The hot rolling process of angle steel is a complex and critical process. By reasonably selecting heating temperature, controlling rolling force and speed, and scientifically selecting cooling methods, high-quality angle steel products can be obtained. In actual production, it is necessary to continuously optimize and improve process parameters to meet the quality requirements of the market for angle steel. I hope this article is helpful for understanding the hot rolling process of angle steel and can provide reference for practitioners in related fields.
