What is H beam?
H-beam steel is a cost-effective and highly efficient structural profile with an optimized distribution of sectional area and an ideal strength-to-weight ratio. It gets its name from its section that resembles the letter “H.”
With all its components arranged at right angles, H-beam steel boasts strong resistance to bending, making its construction process simple, cost-effective, and resulting in lightweight structural strength in all directions. Due to these advantages, it is widely used.

H-beam steel is also known as universal beam, wide flange I-beam, or parallel flange I-beam. Its cross-section comprises web and flange plates.
Internationally, H-beam product standards are divided into two major categories: the imperial system used by countries like the USA and UK, and the metric system used by countries like China, Japan, Germany, and Russia.
Despite the difference in measurement units between the imperial and metric systems, H-beams are usually characterized by four dimensions: the height of the web (h), the width of the flange (b), the thickness of the web (d), and the thickness of the flange (t).
Although the method of indicating the dimensional specifications of H-beams varies across the world, the size specifications and tolerances of the manufactured products do not significantly differ.

H Beam Size and Weight Chart
H-steel is classified into four types, represented as follows:
- Wide Flange H-steel, denoted as HW (W stands for Wide)
- Medium Flange H-steel, denoted as HM (M stands for Middle)
- Narrow Flange H-steel, denoted as HN (N stands for Narrow)
- Thin-wall H-steel, denoted as HT (T stands for Thin)
The cross-sectional diagram and symbols for H-steel are depicted in the figure:

Definitions:
- H — Height;
- B — Width;
- t1 — Web thickness;
- t2 — Flange thickness;
- r — Fillet radius;
- cx — Centroid;

H-beams are categorized by flange width into wide flange, medium flange, and narrow flange H-beams. The product model varies by type, with commonly used specifications as follows:
- Wide flange H-beams (HW): The typical model specifications of wide flange H-beams are often indicated by the product of the web height and the flange width, usually including models such as 100×100, 125×125, 150×150, 175×175, 250×250, 300×300, 350×350, and so on. The denotation method is generally the web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2), often showing a characteristic of identical height and width dimensions.
- Medium flange H-beams (HM): The typical model specifications of medium flange H-beams are usually represented by the product of the web height and the flange width, mainly including models like 150×100, 200×150, 250×175, 300×200, 350×250, 400×300, 450×300, 500×300, and so on. The denotation method is the web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2), typically demonstrating a characteristic where the height dimension slightly exceeds the width dimension.
- Narrow flange H-beams (HN): The typical model specifications of narrow flange H-beams are often expressed by the web height multiplied by the flange width, mainly including models such as 100×50, 125×60, 150×75, 175×90, 200×100, 250×125, 300×150, 350×175, 400×200, 500×200, and so on. The denotation method is the web height (H) × flange width (B) × web thickness (t1) × flange thickness (t2), usually showing a characteristic of a larger height-to-width ratio.

Very Useful , information a
Hi I need HW125X125X6.5X9 and HW100X100X6X8 beams in India. Please advise where I can get. Thank you.

Hi,
Please advise if you get standard off the shelve H-254x254x107kg/m beam? Or is this a non-standard item that needs special manufacture?
Thanks
Is this off standard h-beam: Height=210mm, Width=130mm?
Better still, how do we classify the above dimension?
Engr. A. Ade. Adebayo FNSE
Different countries will have a different standards. And the H beam can be classified by:
(1) Flange width
(2) Use
(3) Mode of production
(4) Size specification
Would a width a 10 in Flanges, 5/8 inch thick x Web 16 inch deep, and 5/8 inch thick, will support what length in feet a commercial building and the columns are the right size
I would like to see an average price per beam. I understand that companies sell them per 10 making the cost per single beam cheaper, but here in Indonesia prices vary a lot and of course there is mark up price. A 250×250 beams 12m long costs us 13.5jt ($910) at one place and 18.1jt ($1220) at another place. Is the steel material different?
Is there a weight vs reinforced foundation volume table? If you need to support the weight of 300+ kg on 2 beams, and the reinforced foundation (chicken claw?) is 50x50x20 mm enough?
