Where is channel steel used more, and where is angle steel used more?

Hello! a. The use of channel steel:

1) Main uses of hot-rolled stainless steel ordinary channel steel (GB707-88): ordinary channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and is often used in conjunction with I-beams.

2) Hot-rolled stainless steel light channel (YB164-63) Hot-rolled light channel steel is a kind of steel with wide legs and thin walls, which has better economic effect than ordinary hot-rolled channel steel. Its sizes range from 5-40. In 1966, the smelting standard specified specifications ranging from 10-40

Main uses: construction and steel frame structure, etc.

b.Uses of angle steel:

Stainless steel angle steel can be composed of various different stressed components according to the different needs of the structure, and can also be used as a connector between components. It is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Stainless steel angle steel is a carbon structural steel for construction, which is a section steel with a simple section, which is mainly used for metal components and the frame of the workshop. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for the production of stainless steel angles is low-carbon square billets, and the finished stainless steel angles are delivered in hot-rolled forming, normalizing or hot-rolled condition.

Channel steel is used in the construction of industrial and mining plants, and angle steel is used in machinery, such as: construction machinery, papermaking machinery, sewing machinery, etc.

Angle. Channel steel is generally carbon structural steel.

Material hand matrix Q235 or low-alloy high-strength structural steel Q345, etc., please refer to the national Bichajin standard GB 50017-2017 table for details.

This kind of need to ask professional manufacturers, there is a Beijing Honghan Iron and Steel Trade in Beijing, in Daxing, you can ask.

The use of angle steel and channel steel wheel reed:

1. Most of the channel steel is made of panel foundation, as well as fixed supports, such as power plants, substation electrical panel foundations.

2. Angle steel can be used to make cable supports, can also be used in distribution boxes, terminal boxes to fix shelves or foundations, and can also be used in the roof trusses on the roof of the roof of the open-air warehouse greenhouse.

Angle steel, channel steel is generally used to make the roof ridge of the house, etc., channel steel can be used to make the support keel of the whole building or used to do the keel of external decoration, and the flat steel is most commonly used to do the grounding of the building.

Channel steel is a long steel with a groove-shaped cross-section, which is a carbon structural steel for construction and machinery, and is a section steel with complex cross-section, and its cross-sectional shape is groove-shaped. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing.

Angle steel, commonly known as angle iron, is a long strip of steel that is perpendicular to each other on both sides. There are equal angles and unequal angles. The two sides of an equilateral angle are equal in width.

Its specifications are expressed in millimeters of side width, side width, and edge thickness. For example, "30 30 3", that is, the side width of 30 mm, the side thickness of 3 mm, etc. It can also be expressed by the model number, which is the number of centimeters of the side width, such as 3

Analysis: 1. Section steel.

There are many varieties of section steel, which is a kind of solid long steel with a certain cross-sectional shape and size. According to the different cross-sectional shapes, it is divided into two types: simple and complex cross-sections. The former includes round bars, square bars, flat bars, hexagonal bars and angle bars; The latter includes rails, I-beams, channel steels, window frame steels and special-shaped steels.

The diameter of the small round steel is called the wire.

2. Steel plates.

It is a flat steel with a large width-to-thickness ratio and surface area. According to the different thicknesses, there are three types: thin plate (thickness < 4mm), medium plate (thickness 4-25mm) and thick plate (thickness "25mm). Steel strips are included within the steel plate category.

3. Steel pipes.

It is a long strip of steel with a hollow section. According to its different cross-sectional shapes, it can be divided into round pipes, square pipes, hexagonal pipes and various different cavity closed-section steel pipes. According to different processing technology, it can be divided into two categories: seamless steel pipe and welded steel pipe.

4. Steel wires.

Steel wire is another cold-worked product of wire. According to different shapes, it is divided into round steel wire, flat steel wire and triangular steel wire. In addition to direct use, steel wire is also used in the production of wire ropes, steel grain lines and other products.

Channel steel is a long strip of steel with a grooved cross-section. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 120 * 53 * 5, indicating a waist height of 120 mm, a leg width of 53 mm of channel steel, a waist thickness of 5 mm of channel steel, or 12 channel steel. Channel steel with the same waist height, if there are several leg widths and waist thicknesses that are not the same, you also need to add a b c on the right side of the model to distinguish, such as 25a 25b 25c and so on.

In construction, channel steel is usually represented by " ", such as: 16, that is, 16 channel steel.

The specifications of the channel steel are indicated:

It is mainly expressed by dimensions such as height (h), leg width (b), and waist thickness (d).

Channel steel (3 photos) said that the current domestic channel steel specifications from 5 40, that is, the corresponding height of 5 40cm.

At the same height, light channel steel has narrower legs, a thinner waist and a lighter weight than ordinary channel steel. No. 18 40 is a large channel, and No. 5 16 is a medium-sized channel. Imported channel steel is marked with actual specifications and relevant standards.

The import and export orders of channel steel are generally based on the specifications required in use after determining the corresponding carbon knot steel (or low alloy steel) steel grade. Aside from the specification number, there is no specific composition and performance series for channel steel.

The delivery length of channel steel is divided into two types: fixed length and double ruler, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel is divided into three types: 5, 12m, 19m and 19m according to different specifications. The length selection range of imported channel steel is generally 6 15m.

Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment and vehicle manufacturing.

The channel steel is a long steel with a groove-shaped cross-section, which is a carbon structural steel for construction and machinery, and a section steel with a complex cross-section, and its cross-sectional shape is groove-shaped. China's channel steel imports are greater than exports. The main production areas are Tangshan Iron and Steel, Baotou Iron and Steel, Shandong Iron and Steel, Huangte, Masteel, Xuangang, Nippon Steel and other steel mills.

It is used to make steel structural parts, such as steel stairs, plant supports, etc.

It is mainly used for support and load-bearing.

The use of angle steel and channel steel is to make shelves.
