How to distinguish between U shaped steel and channel steel U beam specifications

Many friends can't tell which is channel steel, which is C-shaped steel, salespeople are generally asked whether C-beam is channel steel and other questions, but these two kinds of steel itself have a big difference, through the following points, you can clearly distinguish these two kinds of steel.

First of all, the C-shaped steel is processed by hot coil cold bending, with high strength and good toughness, compared with the channel steel, the same strength can save three percent of the raw materials, the channel steel is directly sold by the steel company, the thickness is larger, and its cross-section is groove-shaped.

Secondly, C-shaped steel is usually used in the wall beams, purlins, or brackets and other building components of steel structure buildings, which are commonly used in prefabricated houses, and can also be used in mechanical light manufacturing. Channel steel is mainly used in building structures, vehicle manufacturing, and other industrial structures, and is often used in conjunction with I-beams. Both types of steel, although both are used in building structures, are used in different ways.

Finally, there are many classifications of C-shaped steel, including: galvanized, hot-dip galvanized cable trays, glass curtain walls, unequal shapes, in-rolled edge rows, automotive profiles, etc. Channel steel can be divided into:

Light channel steel, ordinary channel steel, hot-rolled flexible channel steel, cold-formed equilateral unequal channel steel, cold-formed inner and outer curl channel steel.

From the above three points, it is not difficult to see that C-shaped steel and channel steel are still easy to distinguish. Some people will ask, is the U-shaped steel channel steel, and what is the ** of the U-shaped steel? Friends who have such questions can go to see our previous publication of "Is U-shaped steel channel steel", and I won't explain it here.

Channel steel and U-shaped steel are just the difference in the name of the application, which are mainly divided into ordinary channel steel (U-shaped steel) and light channel steel (light U-shaped steel).

It can also be determined that channel steel is formed by hot rolling processing, and U-shaped steel is generally rolled formed in a cold state.

The biggest difference between the two is the thickness: the overall thickness of the channel steel is not the same, and the overall thickness of the light U-beam is the same.

The details are as follows:

Cold-formed U-beam refers to the cold state, professional equipment rolling one-time forming, is an economical cross-section light thin-walled steel, known as steel refrigeration bent high-efficiency and energy-saving profile. According to the shape, it can be divided into four types: cold-formed equal-sided channel steel, cold-formed unequal channel steel, cold-formed inner curling channel steel, and cold-formed outer curling channel steel.

It has a variety of extra-thin, reasonably shaped and complex cross-sections that cannot be produced by hot rolling. Compared with hot-rolled section steel, in the case of the same cross-sectional area, the radius of rotation can be increased by 45 60, and the cross-sectional moment of inertia can be increased by many times, so that the material strength can be used more reasonably;

Compared with ordinary steel structures (i.e., steel structures made of traditional I-beams, channel steels, angle steels and steel plates), steel can be saved by about 25 50. In some cases, the amount of steel used in the cold-formed U-shaped steel structure is equivalent to the amount of steel used in the reinforced concrete structure under the same conditions, which is an economic section steel.

The main features of the U-shaped steel bracket: high pressure, long support time, easy to install and not easy to deform.

Widely used in various fields, its use can be roughly divided into highway guardrail panels, steel structures, steel formwork and scaffolding, ships and bridges, railway vehicles, steel sheet piles, automobiles, containers, transmission towers, etc.

The thickness of the product can be from 20-400mm

The U-shaped steel is the arc transition, which is the meaning of the letter, while the clear angle transition of the channel steel is pure right angle.

1. Channel steel is hot-rolled section steel, and U-beam is usually cold-rolled section steel.

2. The detailed size and mechanical properties of the channel steel have formed a national standard, and the specifications and technical parameters of the GB section steel with reference to the national standard document have not yet formed a national standard.

3. Channel steel is widely used in mechanical engineering, and U-shaped steel is only used in decoration.

Channel steel: 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.

U-shaped steel: a cross-section like an English letter"u"of steel.

Hello, the difference between channel steel and U-shaped steel.

1.Channel steel is a hot-rolled section steel, its detailed size and mechanical properties have formed a national standard, the national standard document refers to GB T707-1988It varies in size from 5 and is also commonly abbreviated or simply C in factories'Steel.

The section steel is usually cold-rolled, its specifications and technical parameters have not yet formed a national standard, usually according to the production needs or customer needs to make the corresponding mold (roll) installed on the rolling mill, the iron sheet is coiled into the required specifications of U-shaped steel.

3.Because of its good mechanical properties, channel steel is widely used in mechanical engineering, while U-shaped steel is a light building hardware product because of its thin wall thickness, which is usually only used in decoration. The above is for reference only!

When it comes to the size of U-shaped steel, many friends really don't know much about it. Due to the fact that there is less contact with U-beam, many friends are too lazy to understand, so when someone asks about U-beam, they don't know how to answer. I hope that through the following introduction, you can know more about U-shaped steel, and we will not be embarrassed if others are asking you.

U-shaped steel, as the main section steel for manufacturing roadway shrinkage metal supports, is widely used at home and abroad. However, the understanding of the performance and requirements of U-beam itself at home and abroad is inconsistent, so the cross-sectional shape, geometric parameters and materials of U-shaped steel in various countries are not the same. There are five main types of U-shaped steel produced in China: 18U, 25U, 29U, 36U, and 40U, so is its size less?

Of course not, don't look at the U-shaped steel only these five models, its specifications and sizes are more, the following is the U-shaped steel size information provided to us by Tianjin Pengjie Weiye. Common U-beam specifications and size table: 60*40(50)*15*( 180*60(70)*20*( 80*40(50)*20*( 200*60(70)*20*( 90*40(50)*20*( 220*70(80)*20*( 100*50(60)*20*( 250*70(80)*20*( 120*50(60)*20*( 300*80(100)*20*( Some friends may ask, I want to find a company that can do it according to the U-shaped steel size determined by our drawings, but what should I do if there is no one on it?

You don't have to worry about this, Tianjin Pengjie Weiye Cold Formed Steel is a professional production of cold-formed steel enterprises, specializing in the production of C-shaped steel, Z-shaped steel, U-shaped steel, strip steel, galvanized C-shaped steel, galvanized U-shaped steel, galvanized Z-shaped steel and other cold-formed steel. Now our company independently has ten of the world's most advanced large-scale automatic CNC cold-forming production lines, and dozens of excellent technical personnel, to solve a series of problems such as incomplete specifications of C, U and Z steel, poor forming, and poor flatness! And the steel in our factory is absolutely high quality and low price.

Welcome to consult and negotiate!

But before that, let's first learn about the relevant knowledge of U-beam. U-shaped steel is a kind of steel with a cross-section like the English letter "U", which is mainly used for the secondary support of mine roadways and the support support of mountain tunnels. However, due to the inconsistent understanding of the performance and requirements of the U-beam itself at home and abroad, the cross-sectional shape, geometric parameters and materials of the U-beam in various countries are not the same.

There are four main types of U-shaped steel produced in China: 18U, 25U, 29U, 36U and 40U. However, the 18U carrying capacity is very low, so it is rarely produced now. In fact, it is not difficult to calculate the size of U-shaped steel, knowing its model and attributes, you can generally understand, let's first look at a commonly used weight table.

The unit weight of each type of U-beam is as follows:

29u29kg/m

Among them, the model with Y after the representation is waist positioning.

Although the models of U-beams are different, they all have the same specifications. Usually, the standard value given to it is completely calculable. It's just that at present, the ** is still in the **, so the Tianjin U-shaped steel ** standard is not easy to say.

In addition to the above general specifications, Tianjin Pengjie Weiye cold bending **** can also be made according to the drawings provided by customers. In order to make U-shaped steel of high quality and low price, the company has introduced ten of the most advanced CNC cold-forming production lines, which is definitely your assured choice.
