H Beam Sizes and Weight Chart | MachineMFG (2024)

The dimensionsand weight ofH-beam steelcan be determined through severalmethods. Themost common approachis to calculatethe cross-sectional areausing the formula:

A = t1(H-2t2)+2Bt2+0.858r2

Where:

  • Hrepresents theheight of theweb
  • B representsthe width ofthe flange
  • t1 represents thethickness ofthe web
  • t2represents thethickness ofthe flange
  • rrepresents theradius of thefillet

Once thecross-sectional area(A) is obtained, the weightper unit lengthof the H-beam canbe easily calculated by multiplying Aby the densityof steel, whichis typically7.85 g/cm3 or0.00785 kg/cm3. Thisstraightforward calculationprovides an accurateestimate of theH-beam’s weightbased on itsspecific dimensions.

To simplify the process of determining the weight of H-beam steel, manufacturers often provide detailed theoretical weight tables for various standard sizes. These tables list the weight per meter for each H-beam specification, making it easy to find the information you need.

For instance, an H-beam with dimensions of 350mm in height and 175mm in width (350175mm) has a theoretical weight of 41.8kg per meter. Similarly, an H-beam measuring 400mm in height and 150mm in width (400150mm) weighs 55.8kg per meter.

These examples demonstrate that the weight of an H-beam is directly related to its dimensions. As the size of the H-beam changes, so does its theoretical weight per unit length. By referring to these weight tables, engineers and contractors can quickly estimate the total weight of the H-beams required for their projects, ensuring accurate material ordering and cost estimation.

While the cross-sectional area formula is the most widely used method for calculating the weight of H-beam steel, there are alternative approaches that can provide similar results. One such method involves using formulas that consider the width of the web plate and the base plate.

Another option is to refer to the standard section sizes and their corresponding weights, which are readily available in reference materials. However, it’s important to keep in mind that these calculations may have slight discrepancies when compared to the actual weight of the H-beam.

Typically, the difference between the theoretical weight and the actual weight falls within a range of 0.2% to 0.7%. This minor variance is due to factors such as manufacturing tolerances and variations in steel density. Despite these potential discrepancies, the formulas and reference tables provide a reliable means of estimating the weight of H-beam steel for practical applications.

What is the specific formula to calculate the weight of H-beam steel based on the width of the web plate and the base plate?

For those who prefer to calculate the weight of H-beam steel using the dimensions of the web plate and base plate, the following formula can be employed:

Weight (kg/m) = 0.00785 × (2.5 × a × t1 + (b – 2 × t1) × t2)

Where:

  • ‘a’ is the width of the web plate in millimeters (mm)
  • ‘b’ is the width of the base plate in millimeters (mm)
  • ‘t1’ is the thickness of the web plate in millimeters (mm)
  • ‘t2’ is the thickness of the base plate in millimeters (mm)

This formula takes into account the height and width of the web plate, as well as the width and thickness of the base plate. By inputting these parameters, the formula calculates the weight of the H-beam steel per meter length.

The constant 0.00785 in the formula represents the density of steel in kg/cm³, which is used to convert the volume of the H-beam (calculated using the plate dimensions) into its corresponding weight.

This alternative method provides a convenient way to determine the weight of H-beam steel when the dimensions of the web and base plates are readily available, offering an additional tool for engineers and manufacturers to accurately estimate the material requirements for their projects.

H-steel is categorized into fourmain types based on the widthof the flange:

  1. WideFlange H-steel (HW)
  2. MediumFlange H-steel (HM)
  3. Narrow Flange H-steel (HN)
  4. Thin-wall H-steel (HT)

The cross-sectional diagrambelow illustrates the keydimensions and symbols used to describeH-steel:

By referringto this table, engineers and contractorscan easily selectthe appropriateH-beam size fortheir specificproject requirements, ensuring optimalstrength, stability, and cost-effectiveness.

CommonH-Beam Specificationsby Flange Width

H-beams are further classified based on their flange width, with each category having its own set of commonly used specifications:

1. Wide Flange H-Beams (HW)

Wide flange H-beams are typically denoted by the product of their web height and flange width. Common models include:

  • 100×100
  • 125×125
  • 150×150
  • 175×175
  • 250×250
  • 300×300
  • 350×350

The notation for wide flange H-beams follows the format: web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2). A key characteristic of wide flange H-beams is that the height and width dimensions are often identical.

2. Medium Flange H-Beams (HM)

Medium flange H-beams are also represented by the product of their web height and flange width. Frequently used models include:

  • 150×100
  • 200×150
  • 250×175
  • 300×200
  • 350×250
  • 400×300
  • 450×300
  • 500×300

The notation for medium flange H-beams is similar to wide flange H-beams: web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2). In medium flange H-beams, the height dimension is typically slightly larger than the width dimension.

3. Narrow Flange H-Beams (HN)

Narrow flange H-beams are denoted by the product of their web height and flange width. Standard models include:

  • 100×50
  • 125×60
  • 150×75
  • 175×90
  • 200×100
  • 250×125
  • 300×150
  • 350×175
  • 400×200
  • 500×200

The notation for narrow flange H-beams follows the same format as wide and medium flange H-beams: web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2). Narrow flange H-beams are characterized by a higher height-to-width ratio compared to the other categories.

Understanding these common specifications and notation methods for each category of H-beam helps engineers, architects, and contractors select the most suitable H-beam for their specific project requirements, ensuring optimal structural performance and cost-efficiency.

What is an H-Beam?

H Beam Sizes and Weight Chart | MachineMFG (2)

H-beam steel is a highly efficient and cost-effective structural profile that offers an optimal distribution of sectional area and an excellent strength-to-weight ratio. Its cross-section resembles the letter “H,” hence its name.The components of an H-beam are arranged at right angles, providing strong resistance to bending forces. This characteristic makes the construction process simple, cost-effective, and results in lightweight structural strength in all directions. Due to these advantages, H-beam steel is widely used in various construction applications.H-beam steel is also known by other names, such as:

  • Universal beam
  • Wide flange I-beam
  • Parallel flange I-beam

The cross-section of an H-beam comprises a web plate and two flange plates, which contribute to its unique properties and performance.

International H-Beam Standards

Globally, H-beam product standards are divided into two main categories:

  1. Imperial system: Used in countries like the United States and the United Kingdom
  2. Metric system: Used in countries like China, Japan, Germany, and Russia

Despite the differences in measurement units between the imperial and metric systems, H-beams are generally characterized by four key dimensions:

  • Height of the web (h)
  • Width of the flange (b)
  • Thickness of the web (d)
  • Thickness of the flange (t)

Although the method of specifying the dimensions of H-beams may vary across different countries and regions, the actual size specifications and tolerances of the manufactured products remain largely consistent worldwide.
