With the rapid development of industrialization, our demand for steel has increased. Channel steel is the most widely used in construction projects. We also need to update the theoretical weight table of Hot rolled carbon astm a36 high quality u-shape channel steel. Learn more. Channel steel and I-beam are mostly used in the same way, and are also the main materials for metal structures in construction and installation projects. Channel steel is also the most common type of steel. Below, Jinsong Steel will share the theoretical weight table of channel steel and the model of channel steel.
Channel steel refers to a long strip of steel with a groove-shaped cross-section. Channel steel is a section steel with a complex cross-section. Channel steel is mainly used in building structures, mechanical equipment, curtain wall engineering, vehicle manufacturing, etc. In the process of use, it is required to have good riveting performance, comprehensive mechanical performance and welding performance. Channel steel is divided into ordinary channel steel and light channel steel. Channel steel is mainly used for building structures, industrial structures, vehicle structures, fixed cabinets, etc. Channel steel can also be used in conjunction with I-beam steel.
The specifications of Hot rolled carbon astm a36 high quality u-shape channel steel are mainly expressed by dimensions such as height (h), leg width (b) and waist thickness (d). At present, the domestic channel steel specifications are from 5-40, that is, the corresponding height is 5-40cm. Under the same height, light channel steel is lighter in weight, narrower in legs and thinner in waist than ordinary channel steel. No. 5-16 channel steel is medium channel steel, and No. 18-40 is large channel steel. The imported channel steel will clearly indicate the actual size and relevant standards. The import and export order of channel steel is based on the specifications required in use after determining the corresponding carbon steel (or low alloy steel) steel grade. Apart from the specification number, there is no specific composition and performance series for channel steel.
Due to the complex manufacturing process of channel steel, the allowable deviation range of channel steel is:
Model 5, 6.3, 6.5, 8, 10, 12, 12.6, 14, 16, 18;
Height (h) ±1.5, ±2.0, ±2.0, ±3.0, ±3.0;
Leg width (b) ±1.5, ±2.0, ±2.5, ±3.0, ±3.5;
Waist thickness (d) ±0.4, ±0.5, ±0.6, ±0.7, ±0.8;
The bending deflection should not exceed 0.15d.
Usually the length is: 5-12m, 5-19m, 6-19m.
The allowable deviation of surface quality and geometric shape of Hot rolled carbon astm a36 high quality u-shape channel steel is specified in the standard. It is required that the surface of the channel steel shall not have any harmful defects or significant torsion. The allowable value of the wave bend of the channel steel and the relevant parameters (h, b, d, t, etc.) of the shape of the channel steel surface of each specification are specified. difference.
If the geometry of the channel steel is incorrect, the main manifestations are: angle, leg expansion and leg merging, etc.
Channel steel theoretical weight table unit: kg/m, mm.
Channel steel theoretical weight table specification representation method: such as 5#50*37*4.5*6.928*5.438, indicating that the specification is 5#, the waist height is 50mm, the leg height is 37mm, the waist thickness is 4.5mm, and the cross-sectional area is 6.928cm. The weight is 5.438.
The following is an introduction to the theoretical weight table of Hot rolled carbon astm a36 high quality u-shape channel steel. Any change in the model, height, leg width, waist height and weight of the channel steel will make the entire channel steel. The parameter follower changes. When changing the volume and shape of the channel steel, the changed value should be within a certain range, so as not to affect the use of the channel steel, so that the channel steel can better play it. its own role.
