Angle steel is a common steel material named because of its angular shape. Angle steel is widely used in construction, bridges, machinery and other fields. According to different classification methods, angle steel can be divided into the following categories:

Classified by angle:

Angle steel can be divided into 45-degree angle steel, 90-degree angle steel and 135-degree angle steel according to angle. A 45-degree angle means the angle between the legs is 45 degrees; a 90-degree angle means the angle between the legs is 90 degrees; a 135-degree angle means the angle between the legs is 135 degrees.

Classification by size:

Angle steel can be divided into large angle steel, medium angle steel and small angle steel according to size. Large angle steel is larger in size and is mainly used for supporting and fixing large buildings and bridges; medium-sized angle steel is moderate in size and is mainly used for supporting and fixing general buildings and mechanical equipment; small angle steel is smaller in size and is mainly used for some light Structure and decoration.

Classified by quality:

Angle steel can be divided into ordinary angle steel and high-quality angle steel according to quality. Ordinary angle steel has a higher carbon content, higher strength and hardness, but poorer toughness; high-quality angle steel has a lower carbon content, with a certain amount of alloying elements added, and has higher strength, hardness, toughness and other properties.

Classification by surface treatment:

Angle steel can be divided into hot-dip galvanized angle steel, electro-galvanized angle steel, painted angle steel, etc. according to surface treatment. Hot-dip galvanized angle steel refers to immersing the angle steel in molten zinc liquid at high temperature, so that a layer of zinc is attached to the surface of the angle steel, which has better anti-corrosion properties; electroplating galvanized angle steel refers to using the angle steel as an anode and electrolyzing it on the angle steel. A layer of zinc is deposited on the surface; painted angle steel refers to coating the surface of the angle steel with a layer of paint or other anti-corrosion coatings to achieve anti-corrosion purposes.

The above are several classification methods of angle steel. Each classification method has its specific application scenarios and characteristics. When selecting and using angle steel, you need to make a selection based on the actual situation. For more information, please contact our online customer service.
