angle steel bar According to the structure of the different

Angle steel commonly known as angle iron, is perpendicular to each other on both sides of the long strip of steel. While the national standard angle is the difference between the GB can guarantee that between GB is the national standard, the same angle angle steel and angle of the angle of the points. The equal length of the equilateral angle is equal. Its specifications are expressed in square meters wide by width and width. Such as "∠ 30 × 30 × 3", that is, the width of 30 mm, 3 mm thick side of the equilateral angle. Can also be used model said, the model is the width of the square meters, such as ∠ 3 #. Model does not mean that the same model in the thickness of the different thickness, and thus in the contract and other documents on the corner width of the angle, the thickness of the thick fill out complete, to avoid the use of models alone. Hot rolled equilateral angle specifications for the 2 # -20 #.

Angular steel can be composed of different components according to the different needs of the structure, but also for the connection between the components. Widely used in a variety of building structures and engineering structures, such as beams, bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Corner steel construction of carbon structural steel, is a simple section of the steel, mainly used for metal components and plant frame. In the use of the requirements of a better solderability, plastic deformation properties and a certain degree of mechanical strength. Production of steel raw steel billet for the low carbon billet, finished angle for the hot-rolled forming, normalizing or hot-rolled state delivery.

Galvanized angle analysis of the surface roughness:

1. Pretreatment process produced "over pickling", diagonal steel galvanized layer surface roughness.

Pickling "to make the steel surface rough or produce bean marks, which is the workpiece after hot galvanized surface rough one of the reasons.

2. Zinc temperature is too high or zinc extraction time is too long, diagonal steel galvanized layer surface roughness.

When the temperature of the zinc solution is too high, the zinc leaching time is too long, or due to the influence of the angle steel component and the Stirling effect, the Zn-Fe alloy phase is too large or uneven, and the surface roughness is caused. The more easily appear rough.

Hot-dip galvanized steel removed from the zinc solution after the slow cooling, or steel section is too thick, or hot galvanized angle steel without isolation immediately after the stack and other reasons, there will be surface roughness.

3. Henan angle steel manufacturing selection of steel composition or surface conditions, diagonal steel galvanized layer surface roughness.

Galvanized layer surface is smooth and rough, is relatively speaking.With steel plate, steel pipe or wire "continuous hot galvanizing" different, steel angle hot galvanized steel is part of the category of hot galvanizing process, galvanized layer without air knife If the surface of the steel used in the hot galvanized angle steel is rough, there is a rusty pit or a significant rolling stripes. After the hot galvanizing is completed, the surface is generally not smoother than the original.
