The specifications and dimensions of the channel steel are.

1) Height: 120mm

2) Leg width: 53mm

3) Waist thickness:

4) Theoretical weight:

There are two types of channel steel specifications:

A: height 160mm, leg width 63mm, waist thickness, cross-sectional area, weight;

B: height 160mm, leg width 65mm, waist thickness, cross-sectional area, weight.

The specifications of the channel steel are expressed in millimeters of height (h) * leg width (b) * waist thickness (d), such as 200 * 40 *, indicating that the waist height is 200 mm, the leg width is 40 mm, and the waist thickness is mm of channel steel, or 10 channel steel. Channel steel with the same waist height, if there are several different leg widths and waist He Huihou, you also need to add a, b, and c on the right side of the model to distinguish them, such as 28 a, 28 b, 28 c, etc.

The specifications of domestic channel steel are from No. 5-40, No. 5-16 channel steel is medium-sized channel steel, and No. 18-40 is large channel steel.

The 20A specification is: 200*73*The weight per meter isExtended information: Channel steel is divided into ordinary channel steel and light channel steel.

The specification of hot-rolled ordinary channel steel is 5-40. The specifications of the hot-rolled flexible channel steel hail shed agreed by the supply and demand parties are. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panel cabinets, etc., channel steel is often used in conjunction with I-beams.

According to the shape, the channel can be divided into 4 types: cold-formed equal-sided channel, cold-formed unequal channel, cold-formed inner curling channel, and cold-formed outer curling channel. According to the theory of steel structure, it should be the channel steel wing plate stressed, that is, the channel steel should be upright, not lying on its stomach.

16. There are 2 types of channel steel specifications, one is h=160

b = 63 TW = cross-sectional area is.

Weight per meter.

The outer surface area is.

The other is h=160

b = 65 tw = cross-sectional area is.

Weight per meter.

External surface area.

Channel steel models 25A, 25B, 25C have the following areas:

1. The leg width is different, the leg width of 25A is 78 mm, the leg width of 25B is 80 mm, and the leg width of 25C is 80 mm;

2. The waist thickness is different, the waist thickness of 25A is 7 mm, the waist thickness of 25B is 9 mm, and the waist thickness of 25C is 11 mm;

3. The cross-sectional area is different, the cross-sectional area of 25a is, the cross-sectional area of 25b is, and the cross-sectional area of 25c is;

4. The theoretical mass of each meter is different, 25a meters weigh kilograms, 25b meters weigh kilograms, and 25c meters weigh kilograms;

5. Due to the different cross-sections, the moments of inertia of the cross-sections are different for the x-axis and y-axis;

6. Because the cross-section is different, they have different strength, stiffness and stability against tensile, compressive and bending resistance.

The cross-sectional height of 25A channel steel is 250mm, the leg width is 78mm, the waist thickness is 7mm, the cross-sectional area is adjusted.

Channel steel is a long steel with a grooved cross-section, which is a carbon structural steel for chain excavation 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.

In use, it is required to have good welding width, riveting performance and comprehensive mechanical properties. The bright core of the raw material billet for the production of channel steel is carbon knot steel or low-alloy steel billet with no carbon content. The finished channel is delivered in hot-formed, normalized or hot-rolled condition.

Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100 * 48 *, which means that the waist height is 100 mm, the leg width is 48 mm, and the waist thickness is millimeters. Channel steel with the same waist height, if there are several different leg widths and waist thicknesses, you also need to add ABC on the right side of the model to distinguish, such as 25 A25 B25 C, etc.

20A channel steel is a common type of I-beam, and its dimensional drawing contains the following elements:

1.The overall ruler of the steel is changed to the inch: what is the overall length of the 20A channel steel and how much is the overall width. These dimensions are usually expressed in millimeters.

2.Size of the internal groove: The 20A channel has an intermediate channel, the size of which determines the cross-sectional shape of the steel. The width and depth of this channel are also usually expressed in millimeters.

3.Thickness of steel: What is the cross-sectional thickness of 20A channel steel. This thickness is often expressed in millimeters for silver negotiations.

With this dimensional information, the geometry and dimensional characteristics of the 20A channel can be determined. These features are very important in engineering design and structural calculations because they determine the strength and load-bearing capacity of the steel.

In practical applications, 20A channel steel is often used in construction, bridges, ships, machinery and equipment and other fields. According to different engineering needs, you can choose the appropriate 20A channel steel size to meet the design requirements.

In summary, the dimensional drawings of the 20A channel provide detailed information about the size and geometry of the steel, which is important for engineering and structural calculations. In practical applications, it is necessary to choose the appropriate 20A channel size according to the specific needs.
