Angle steel is a carbon structural steel for construction, which is a simple-section shaped steel. It is mainly used for metal structures and the frames of buildings, etc. It requires good weldability, plastic deformation properties, and certain mechanical strength during use.
The manufacturing process for angle steel is relatively simple, and the production process can be divided into hot rolling and cold bending. Hot rolling is used for larger-sized angle steel, while cold bending is generally for smaller sizes. The standard process involves passing billets (such as square billets) through a rolling mill multiple times to gradually roll them into a V-shape. The material features *, with a transition arc on the inside of the angle for mechanical properties **. On the other hand, smaller workshops produce angle steel by directly rolling (bending) sheets or strips, without a transition arc on the inside of the angle, and there is a significant internal stress at the bend due to the bending process.

The characteristics of angle steel include:
Low processing costs: The cost of hot-dip galvanized anti-corrosion is lower than that of other paint coatings.
2. Durable: Hot-dip galvanized angle steel features a glossy surface, even zinc coating, no missed areas, no drips, strong adhesion, and excellent corrosion resistance.
3. **Good Properties: The galvanized layer is metallurgically bonded to the steel, becoming a part of the steel surface, thus the durability of the coating is**.
4. Strong coating tenacity: The galvanized layer forms a unique metallurgical structure that can withstand mechanical damage during transportation and use.
5. Corrosion Protection: Every part of the plated piece is zinc-coated, ensuring protection even in recesses, sharp corners, and concealed areas.
6. Time and Effort-Saving: The galvanizing process is faster than other coating methods, and it eliminates the need for on-site painting after installation.

Angle steel manufacturing requirements:
Angle iron is a lathe attachment made of cast iron, typically featuring two perpendicular working surfaces. It has through holes of varying lengths to accommodate screws. Due to the different shapes and sizes of workpieces, angle irons come in both internal and external types and can be made in different shapes to meet various machining requirements. They should possess sufficient rigidity and strength to minimize clamping deformation. To achieve this, in addition to adding some ribs and rib plates structurally, aging treatment should be applied after casting. The working surfaces and positioning benchmarks of the angle iron are ground or finely lapped to ensure good contact performance and accurate angles. They are usually used in conjunction with face plates.

The application range of angle steel:
Angle steel can be assembled into various types of load-bearing components according to different structural requirements and also serves as connecting elements between components. It is widely used in various architectural and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouse shelves, etc. Additionally, it is often used to protect columns and retaining walls, which are prone to collisions.
Angle steel is a carbon structural steel used for construction, featuring a simple cross-section and is primarily used for metal components and the frames of buildings. It offers good weldability, plastic deformation capability, and certain mechanical strength during use. The raw material for producing angle steel is low-carbon square billets, and the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled condition.
