H-beam steel

What is H-beam steel?

Maybe you’ve known, seen, or heard about it. But have you really understood all about H steel?

Honestly…. Tiger Steel also wants to share and ask you to compare and verify if the following information is accurate. I hope to get a positive response from you guys.

First, what Tiger Steel  wants to share is

How to read the parameters of H-beam steel

Ah… This sounds easy huh? But maybe many new brothers learn about the steel industry. Or the structural engineers who just graduated from school probably don’t know that.

Here’s an example!

The project requires H steel with parameters: H175x175x7.5×11

s far as  Tiger Steel  is known, the above parameter will mean something like this:

The second thing, Bao Tin Steel  wants to share

Specifications of H-beam steel at Tiger Steel

For you to easily visualize and grasp the idea. Then  Tiger Steel has made a table of H steel specifications as follows. Let’s see!

H beam Steel 400 H400x400 12 19 6m – 12m 172
There is one thing that surely many brothers are confused about. Tiger Steel also. Or this is wrong.
That is, how to distinguish H and I sections. Or how are H and I steels differently?

What is the difference between H-beam steel and I-beam steel?

This problem is difficult.
It is very difficult for non-specialists to recognize because the two types are so similar.
At first,  Tiger Steel also lagged in this part a lot.
Maybe when you search for information online, you will see information like:
  • H steel has an H-beam cross-section, and I steel has an I-beam cross-section. This is not certain, and if you are not in the industry, do you know what the cross-section is?
  • H-steel has a wide wing, while I-steel has a smaller wing. This view is partly right and partly wrong. In a little while you will understand.
  • Or many pages also mention that H-beam steel is stronger than I-beam steel. But no website will explain to you why.

Tiger Steel will state its views and comments sequentially for each product. So that you guys can understand.

The characteristics to be considered for comparison will include:

  • Shape
  • Crafting method
  • Weight/meter
  • Flange shape (wing)
  • Force-resistance
  • Working altitude
  • Torsional load capacity

Identification characteristics of H-beam steel

H beam
Drawings of H-beam steels

That’s what you see. As soon as I look at the picture, I can see that point 2 above is somewhat inaccurate.

  1. H-beam steel is a type of steel beam made of rolled steel shaped like the letter “H”. H-sections are manufactured as combined parts. That is, the flanges are welded to the “Belly” section to form the H-section. Therefore, the H-beam is also known as the wide flange beam.
  2. Compared with the I-beam, the blade thickness of the H-beam is larger. It is due to this additional thickness that the bearing capacity of the H-beam is greater
  3. The flanges of the H-beam are of equal thickness and are parallel to each other. They are longer, wider, and heavier than I-beams.
  4. The cross-section of the H-beam is more optimized than that of the I-beam, making it a reasonable bearing-to-weight ratio. That is, the intensity per unit area is higher. They have a larger cross-sectional surface area and therefore higher strength.
  5. The wider flange enables the H-beam to achieve a greater moment of inertia and higher strength. Therefore, they have better-bending resistance than I-beams.
  6. H-beams are used for spans up to 100,584 m and can be built to any size and height.
  7. H-beams are heavier than I-beams. This feature is obvious. With the same belly size and wider wings, it’s definitely heavier.
  8. H beams can withstand direct and tensile loads. Its wide cross-section allows it to withstand torsional loads.

➡️ H-beams are used as bearing columns for commercial buildings, platforms, bridges, etc. Wide flange beams are commonly used in civil engineering.

I-steel identification characteristics

I beam
I-beam steel sectional drawing
  1. I-beam is a type of steel girder made by milling or rolling an I-beam. That is, it is made from a single block of steel (iPhone style with a monolithic metal shell, brothers and sisters).
  2. The flange of an I-beam is thinner than that of an H-beam.
  3. The flanges of the I-beam are tapered with an inclination of 1:10 for better load-carrying capacity. They are thinner than the flanges of H-beams.
  4. The cross-section of the I-beam is usually deeper than the width, so it is resistant to local warping.
  5. The moment of inertia of the I-beam is smaller than that of the H-beam, so the anti-bending effect is less.
  6. I-beams are used for spans from 10 to 30.5 meters.
  7. Compared with H-beam, I-beam is light in weight.
  8. I-beams are subjected to direct and tensile loads. However, due to their small cross-section, they cannot withstand torsional loads.

➡️ I-beams are suitable for making support frames and columns for elevators, trailers, tram tracks, hoists, steel structures, and bridges.

Above is a comparison of the differences between the two types of shaped steel, H and I. If you still have questions. Please contact  Tiger Steel at 0932 059 1760932 059 176
