HE..beams in steel structures

Steel Beams, described in this article, are construction elements widely used in industry, and are known for their high strength, structure and mechanical properties.

When we talk about the petrochemical industry, you see very tall steel columns and large, long pipe racks, usually made of large beams. Besides the petrochemical industry, they are widely used in the construction of buildings, bridges, wind turbines, and ships. All profiles have different tonnage capacities, depending on their dimensions.

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.
If anyone reads this article and has a valid explanation for the above statement, please let me know.

HEA HEB HEM Beams

All three profiles (European Wide Flange Beams) also known as steel H beams, and are essential structural elements characterized by their H shaped cross 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 H-beam consists of two basic parts, both of which can vary in size for different applications.

Differences between HEM and HEA/HEB beams

HEM, HEA, and HEB steel beams are all types of European wide-flange beams, each with its own characteristics and applications. These beams are part of the broader family of I beams used in construction and engineering because of their ability to provide efficient structural support.
The differences:

HEM Steel Beams

• Profile: HEM (Heavy Extra M) beams have the largest dimensions of the three types, including wider flanges and a greater depth.
• Characteristics: They feature thicker flanges and webs compared to HEA and HEB beams, making them extremely strong and capable of carrying large loads over long spans.
• Applications: Due to their significant size and weight, HEM beams are typically used in heavy construction projects, large buildings, bridges, and other structures requiring a high degree of structural support.

HEB Steel Beams

• Profile: HEB (High EN B) beams fall between HE and HEM beams in terms of size and weight. They have wider flanges than HEA beams, but are narrower than HEM beams.
• Characteristics: These beams offer a higher load-bearing capacity than HEA beams due to their larger flange width and depth.
• Applications: These beams are suitable for medium to heavy construction projects, including commercial and industrial buildings, bridges and other structures requiring significant support.

HEA Steel Beams

• Profile: HEA (High EN A) beams are lighter than HEB and HEM beams and have thinner flanges and webs.
• Characteristics: These beams offer a good balance between strength and flexibility, making them suitable for a wide range of structural applications.
• Applications: These beams are widely used in residential, commercial, skeletal, and load-bearing construction where load requirements are moderate.

Key Differences HEM/HEA/HEB

HEM beams are the heaviest and offer the highest load-bearing capacity, making them suitable for heavy-duty applications.
HEB beams are medium-sized and offer a balance between weight and structural support.
HEA beams are the lightest and ideal for applications where weight savings and structural integrity are important.

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.
