Angle steel is mainly used to make frame structures, such as tower frames for high-voltage transmission, frames on both sides of steel bridge main beams, columns and arms of tower cranes on construction sites, columns and beams in workshops, and small places such as flower pot shaped shelves on holiday roadsides, and shelves for hanging air conditioning and solar energy under windows.

Requirements for angle steel production:

Angle iron is a lathe accessory made of cast iron, usually with two perpendicular working surfaces. There are through holes of different lengths on the angle iron for connecting screws. Due to the different shapes and sizes of workpieces, angle irons can be made into different shapes in addition to inner and outer ones to meet different processing requirements. It should have a certain degree of rigidity and strength to reduce clamping deformation. Therefore, in addition to adding some ribs and rib plates to the structure, aging treatment should also be carried out after casting. The working surface and positioning reference of the angle iron must be ground or finely scraped to ensure good contact performance and accurate angle. Usually, angle iron is used in conjunction with flower plates.

The characteristics of angle steel include:

1. Low processing cost: The cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings;

2. Durable and long-lasting: Hot dip galvanized angle steel has the characteristics of surface gloss, uniform zinc layer, strong adhesion, and strong corrosion resistance;

3. Good reliability: The galvanized layer is metallurgically bonded to the steel and becomes a part of the steel surface, so the durability of the coating is relatively reliable;

4. Strong toughness of the coating: The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use;

5. Time and effort saving: The galvanizing process is faster than other coating construction methods and can avoid the time required for painting on the construction site after installation.

Appearance quality of angle steel:

1. The surface quality of angle steel is specified in the standard, and generally requires that there should be no harmful defects during use, such as delamination, scarring, cracks, etc;

2. The allowable range of geometric deviation of angle steel is also specified in the standard, generally including curvature, edge width, edge thickness, apex angle, theoretical weight, etc., and it is stipulated that angle steel shall not have significant torsion.

The application scope of angle steel:

Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. Widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves. It is also commonly used to protect vulnerable parts such as columns and retaining walls.

Angle steel belongs to carbon structural steel used in construction, which is a simple section steel material mainly used for metal components and the frame of factories. It has good weldability, plastic deformation ability, and certain mechanical strength in use. The raw steel billets for producing angle steel are low-carbon square steel billets, and the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled state.
