IPE and IPN Profiles in steel structures |
IPE and IPN Profiles are construction elements widely used in industry, and are known for their high strength, structure and mechanical properties.
The applications of both profiles are very diverse. The petrochemical industry
is a popular customer, but they are also used in construction for lightweight structures, commercial
buildings, lightweight architectural designs, and heavy-duty structures such as storage shelving
and bulk storage racks.
These profiles also demonstrate their durability and strength in the construction of bridges and
railway platforms. Even some types of pipe supports use these profiles due to their narrow flange
shape and relatively long height.
Types of Steel profiles
Foreword: A
section greater than or equal to 100mm is (unofficially) called a beam, while smaller dimensions
are still called profile steel or steel section.

above statement, please let me know.
IPE and IPN Beams
Both profiles also known as steel I beams, and are essential structural elements characterized by that cross-section.
IPE section
INP section
These beams are designed to support heavy loads and offer excellent stability and strength for construction projects. They are manufactured by hot rolling and are available in various sizes and material grades to meet a wide range of project requirements.
Part names for these beams
While the strength of a beam depends partly on the strength of the steel, it also depends on its shape. Steel I beam consists of two basic parts, both of which can vary in size for different applications.
Flanges:
The horizontal sections at the top and bottom are called flanges. Flanges are designed to resist
the bending moment or forces that the beam experiences.
Web: The web of a beam is the vertical section that connects the two flanges at the center. The web is designed to resist shear forces that can cause collapse or failure. The web and flanges together provide great strength under shear and bending forces. This is why girders are so commonly used in bridges and building structures. However, the shape of a beam has relatively low resistance to torsional forces. |

Differences between IPE and INP beams
IPE beams (European I beams)
IPE beams have a characteristic I shaped cross-section with parallel flange faces and a relatively uniform thickness across the flanges and the web. The flanges are wider than those of IPN beams, providing a larger supporting surface.
The design of IPE beams focuses on optimizing their strength-to-weight ratio, making them lighter than IPN beams of comparable dimensions. This is achieved through optimized material distribution within the beam's cross-section.
Due to their efficient design and strength, IPE beams are widely used in a wide range of structural applications, such as building frames, bridges and supporting structures where weight savings are important without compromising structural integrity.
IPN Beams (European Standard Beams)
IPN beams, due to their tapered flanges, may require more material in some cases, but offer better performance under specific bending loads.
IPN beams are generally lighter and more material-efficient for general construction projects where balanced load distribution is sufficient.
IPN beams are generally more expensive, but offer better performance for projects requiring high structural integrity under load-bearing conditions.
Key Differences IPE vs. IPN
IPN beams, due to their tapered flanges, may require more material in some cases, but they offer superior performance under specific bending loads.
IPE beams are typically lighter and more efficient in terms of material usage for general construction projects where balanced load distribution is sufficient.
IPN beams are generally more expensive but offer better performance for projects requiring high structural integrity under load-bearing conditions.
Materials and Material Grades
Materials are available in a wide range of carbon steels and stainless steels.
Carbon steel grades range from alloyed and unalloyed to heat resistant steels, while stainless steel grades include austenitic stainless steels and other stainless steels, such as duplex and superduplex.
