H-beam steel comes in an extensive range of sizes and specifications, offering great design and construction flexibility for diverse projects. Its specific dimensional parameters may vary in line with regional industry standards and individual manufacturer’s technical specifications. That said, we’ve listed some of the most commonly used sizes and dimensions of H-beam steel for your reference below.

Height (H): The height of an H-beam steel refers to the vertical distance between the top and bottom flanges. Millimeters (mm) or inches (in) are commonly used measurement units.

Flange Width (B): The flange width of an H-beam steel refers to the horizontal width of each flange. Millimeters (mm) or inches (in) are commonly used measurement units.

Web Thickness (t1): The web thickness of an H-beam steel refers to the thickness of the vertical web connecting the two flanges. Millimeters (mm) or inches (in) are commonly used measurement units.

Flange Thickness (t2): The flange thickness of an H-beam steel refers to the thickness of each flange. Millimeters (mm) or inches (in) are commonly used measurement units.

For example, a common H-beam steel size might be denoted as “H-beam 200x200x8x12,” where:

Height (H) = 200 mm

Flange Width (B) = 200 mm

Web Thickness (t1) = 8 mm

Flange Thickness (t2) = 12 mm

This indicates that the H-beam has a height and flange width of 200 mm, a web thickness of 8 mm, and a flange thickness of 12 mm.

H-beam steel standards

Our H-beam steel product line now covers a full range of commonly used models including H100, H125, H150, H200, H250, H300, H350 and H400, all of which enjoy widespread application across industries. Manufactured in strict adherence to international quality and dimensional standards, these H-beam steel products are extensively adopted in both industrial manufacturing and building construction sectors for various structural applications.

H-beam steel is imported from countries such as Taiwan, Russia, China, Japan, the UK, and the US.

Standards for H-beam steel include: ATSM, DIN, ANSI, EN, GOST 380-88, JIS G3101, SB410, 3010.

Steel grades for H-beam include: S355JO, S275, S275JR, S275JO, S235, S235JR, S235JO, ASTM A36, JIS G3101 SS400, Q345B, A572 Gr50, S355, S355JR.

Russian steel grades for H-beam include: CT3,.. with the standard GOST 380-88.

Japanese steel grades for H-beam include: SS400,.. with the standard SB410, 3010.

Chinese steel grades for H-beam include: SS400, Q345B,… with the standard JIS G3101, SB410, 3010.

US steel grades for H-beam include: A36,.. with the standard ATSM A36.

Choosing the Right Grade

When selecting a steel H-Beam grade, consider the following factors:

Load requirements: Higher strength grades (e.g., Q345, A572) for heavy loads.

Environmental conditions: Stainless steel or galvanized for corrosive environments.

Budget: Carbon steel grades (e.g., Q235, A36) for cost-effective solutions.

For specific standards, H-beam steel includes the parameters:

H: height of the steel column

B: width of the steel flange

t1: thickness of the steel web

t2: thickness of the steel flange

L: length of the steel column

W: steel weight, calculated in Kg/m

H-beam steel dimensions

As indicated by the collected data, the standard length range of H-beam steel generally falls between 6 meters and 15 meters. In practical applications, the most commonly supplied lengths are 6 meters and 12 meters, with the 12-meter specification being the most favored and widely used option in the market.

For H-beam steel with non-standard dimensions or special specifications that deviate from regular industry norms, buyers typically conduct separate negotiations with manufacturers to customize production. When such special-spec H-beam steel cannot be manufactured domestically, importing the required products becomes a viable and common solution.

1. What is an H-beam?

An H-beam (or I-beam) is a structural steel component with an "H"-shaped cross-section, designed to provide superior load-bearing capacity in construction and engineering projects.

2. What are the common grades of H-beams?

Popular grades include:

ASTM A36 (General construction, moderate strength)

ASTM A572 Gr.50 (High-strength for bridges & heavy structures)

Q235B / Q355B (Chinese standards for buildings & infrastructure)

S235JR / S355JR (European standards for industrial use)

JIS SS400 / SM490 (Japanese standards for heavy-duty projects)

3. What are the key applications of H-beams?

High-rise buildings (Steel frames, columns, and beams)

Bridges & highways (Long-span support structures)

Industrial warehouses & factories (Heavy-load roofing and flooring)

Shipbuilding & offshore platforms (High-strength structural support)

Railway & infrastructure (Tunnel supports, crane beams)

4. What’s the difference between H-beam and I-beam?

H-beam: Wider flanges, more load-bearing capacity, used in heavy construction.

I-beam: Thinner flanges, lighter weight, used in residential or light commercial projects.

5. How do I choose the right H-beam size?

Key factors:

Load requirements (Heavier loads need larger beams like 400x400mm)

Span length (Longer spans require higher moment of inertia)

Building codes (Check local standards like ASTM, EN, or GB)

6. Can H-beams be welded or drilled?

Yes, but proper techniques are needed:

Pre-heating may be required for thick beams (e.g., S355JR).

Use low-hydrogen electrodes for welding high-strength grades.
