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-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:

1. 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.
2. 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.
3. 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.
