Beam is a profile whose main task is to withstand stresses due to shear force and flexural anchor and its main use is in the construction industry. In the production process of this product, hot rolling is used and there are only some different stages in normal production and its hash.
This steel product, which is widely used in buildings, is divided into various groups based on the ratio of wings and offerings. In this article, we intend to first briefly introduce this product and then examine its types.
Beam is used as a metal structure widely used in the construction industry in different types depending on its tasks and role, and its types include IPE , INP, IPB and honeycomb beams.

Learn more about beams

Beam is a well-known profile with cross-section in the form of I and H, which is made of different steel alloys; This product is widely used in building construction; So that steel frame buildings without this profile will not exist externally. The main task of this type of profile in structures is to withstand and transfer the load on the building, it is also used in the design of columns, trusses and beams as the best option. This profile consists of two parts, wing and soul, the main and middle part of the beam is called life and the edges and sides of that wing are called. The high volume of use of this product has made the price of beams one of the determining factors in the cost price of the building.

Advantages of using beams

Development is possible after the completion of the structure.
It is possible to connect several pieces to each other.
These are parts that are prefabricated in factories.
Its execution and installation is high speed.
They are widely used at high altitudes.



We see a view of the use of metal in structures.

Disadvantages of using beams

Corrosion of metals against external factors: Metal parts used in buildings react to weather conditions; This reduces the size of the metal parts. Therefore, we will face an increase in building maintenance and maintenance costs.
Tendency of metal parts to buckle: Tendency of metal parts to buckle is considered as a weakness for these products.
Improper connection of parts: The connection of metal parts to each other is usually done with rivets and screws. But in our country, most of the connections are welded, on the other hand, due to the lack of skills of welders and lack of control by supervising engineers, they will face problems later.

Types of beams

In the following, we intend to introduce different types of beams. Its diversity is mostly due to its mechanical properties and appearance, and each has its own application in different industries:

IPE beam

It is known as an ordinary beam and is similar in appearance to the English I. Its production method was in accordance with European standards; The wings have been shown solely to give a sense of proportion. The wings have been shown solely to give a sense of proportion. Structures that are made in Iran and designed by Iranian engineers are usually based on this standard, which is why this type is especially popular among customers.

Beam INP

This type, like IPE, is I-shaped and is produced according to Russian and Chinese standards. The only difference between this type and IPE is the wing thickness, in INP the wing thickness decreases with distance from the die.
These two types, in addition to being produced domestically, are also imported in the iron market.
IPE and INP beams are very similar to each other. In many cases, after purchasing the beam, at the unloading site or even after the construction of most of the building has been completed, they find that the beam used is wrong, so it is recommended Be careful in identifying the type used.
Wing Beam (Hash or IPB)
Wing beam or hash is one of the sub-branches of beam, its beam in the form of light, heavy and super heavy is the sign and abbreviation of these beams as follows. If the wing of the beam is equal to its life, it is called the wide-wing beam (hash). Iron Online specializes in the sale and supply of heavy-duty beams, so that our experts will guide you in buying. Hash is produced in 1000-100 sizes. Zobahan production plant will launch a new production line with the aim of presenting it in 160, 180 and 200 sizes.

HEB Heavy Wing
HEA style wide wings
Heavy TPB

Heavy-duty Wing Beam (HEB) is thicker than light Wing Beam (HEA), so the weight of light and heavy Wing Beam is different in different sizes, the beam is available in sizes 10 to 1000. To understand the difference between light and heavy weights, we examine them in two weight sizes; In size 10, the light type weighs 200 and in the heavy type weighs 240 kg, but in size 90, the light type weighs 3 tons and 200 kg and in the heavy type weighs 3 tons and 550 kg.

Note: The acronym V in this area means heavy arrow and the L symbol indicates light arrow. IPBV means heavy beam and IPBL is wide beam.

What is Honeycomb Beam (CPE)?

In order for the beam to be able to withstand the bending anchor to a greater extent, its core is cut into a trapezoidal shape and welded as shown below, which is called a honeycomb. This species has hollow cavities throughout its life, which makes it look like a beehive.

The benefits of honeycomb beams

They are lighter in weight, so they are more economical.
As mentioned above, the honeycomb beam has empty holes in the beam core, which is an advantage because these holes are a good space for the passage of electrical pipes and installations.

Disadvantages of honeycomb beams

Due to the presence of holes in the core, the shear strength at the junction of the bridge and the columns is reduced. Sheets are sometimes used to fill these holes.
It is welded all over for integration.
What is the difference between beams and joists?

In the structure, the beams are divided according to the type of load and their application. For example, in the girder position, which is located horizontally, as the main support, it transmits the loads from the beams to the columns. But the beam, which is usually smaller and lighter than the original model, is attached to the beam, transmits the load to it and is not directly connected to the columns. Despite the differences, both the beam and the beam have the main task of resisting the bending force.

Conclusion

In this article, we talked about the nature of steel beams and their types, ie IPE, INP, IPB and CPE beams, each of which is different in terms of appearance and application. It was also said about the differences between arrows in different applications and tasks. If you have any experiences with the structure and types of beams used in the building, let us know.
