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.

Angle iron 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, etc. Small places such as flower pot shaped shelves on holiday roadsides, and shelves for hanging air conditioning and solar energy under windows. 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 steel for connecting screws. The allowable range of geometric deviation of the angle steel is also specified in the standard, generally including curvature, edge width, edge thickness, top angle, theoretical weight, etc. It is also stipulated that the angle steel shall not have significant torsion. Angle steel is a carbon structural steel for construction, which is a simple section steel mainly used for metal components and factory frames. It is required to have good weldability, plastic deformation performance, and certain mechanical strength in use.

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.

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.
