Girder

Girder:

A beam is a type of steel profile that is used to make the skeleton of structures, columns, trusses, and beams, and it has the necessary strength to withstand bending loads and shear anchors. This product is produced either in the form of the English letter H or I, each of which has different types. H-shaped profiles are known as Hash beams.

Types of iron beams:

1. IPE beam

This product is the most widely used type of iron beam in the Iranian market, and Iranian building plans are drawn according to the same standards, and this is why IPE or ordinary beams are so useful. The most important feature of these beams is the equal size of the wings along the entire length of the branch.

2. IPB beam

Hash or wide beam is one of the other widely used profiles in the Iranian market, which is used in large construction projects such as the construction of commercial complexes, factory sheds, etc.

3. INP beam

These beams are also I-shaped, but the shape of their wings is different from the IPE type. In INP beams, the thickness of the wings increases as you approach the body, so when you look at this product from the front, the wings are sloped.

4. CPE beam

In the body of the honeycomb beams, there are octagonal holes that are similar to beehives, and this is the most important difference between these steel profiles and other types of beams. Despite these holes, it is possible for connections and wires to pass through the skeleton of the structure, but the bending resistance of these beams is lower than other types of beams. CPE ratio.

Applications of steel beams

• Construction of the building frame
• Construction of beams and trusses
• Column construction
• Use in column base and steel plates
• Bridge construction
• Construction of ships and docks
• Construction of oil and gas structures
• In humid environments or environments with chemical vapors, there is a possibility of rusting and oxidation of the beam body.
• There is a possibility of bending the beams if they are used non-standardly.
• Beams in Iran are usually connected by welding, this method is not safe for connection. At the international level, they use bolts and nuts and connections suitable for iron beams.
• Iron beams do not have much resistance to high temperature; Therefore, in a fire, the structure collapses very quickly.
