Hot-Rolled H-Shaped Steel and Available Sizes
Introduction
Hot-rolled H-shaped steel is one of the most common structural materials used in construction, manufacturing, and industrial constructions. Characterized by high strength, strength-carrying capacity, and economic affordability, H-beams offer higher support compared to any other steel profile.
This handbook discusses the advantages, uses, and sizes available of hot-rolled H-shaped steel, allowing you to select the proper beam for your project.
What is Hot-Rolled H-Shaped Steel?
Hot-rolled H-shaped steel, or simply an H-beam, is a structural profile steel with the cross-section in the shape of the letter “H.” Hot-rolling produces it, shaping the steel while hot to provide more durable and stronger beams.
Characteristics of H-Shaped Steel
- Wide Flanges – Provides better load distribution and stability.
- High Load-Bearing Capacity – Ideal for heavy-duty applications.
- Efficient Weight Distribution – Reduces material waste while maintaining strength.
- Easy to Weld & Fabricate – Can be cut, drilled, and modified for various applications.
Applications of Hot-Rolled H-Shaped Steel
1. Construction & Infrastructure
- Used in buildings, bridges, and skyscrapers for structural support.
- Provides high load-bearing strength for vertical and horizontal frameworks.
2. Industrial & Mechanical Engineering
- Essential in factory buildings, warehouses, and steel frames.
- Used in heavy machinery and equipment structures.
3. Shipbuilding & Marine Applications
- H-shaped beams provide reinforced frameworks for ships and offshore structures.
- Resistant to high-pressure loads and extreme weather conditions.
4. Transportation & Automotive Industry
- Used in railway tracks, truck frames, and support systems.
- Reduces overall weight while maintaining high strength and durability.
Hot-Rolled H-Shaped Steel Sizes
Standard Dimensions and Specifications
H-shaped steel beams are available in various sizes and weights depending on the application. The following table provides common hot-rolled H-beam sizes:
| H-Beam Size (mm) | Flange Width (mm) | Web Thickness (mm) | Weight (kg/m) |
| 100 x 100 | 50 | 5 | 17.2 |
| 150 x 150 | 75 | 6 | 31.5 |
| 200 x 200 | 100 | 8 | 49.9 |
| 250 x 250 | 125 | 9 | 72.4 |
| 300 x 300 | 150 | 10 | 94.5 |
| 350 x 350 | 175 | 11 | 124 |
| 400 x 400 | 180 | 13 | 157 |
| 450 x 450 | 190 | 14 | 180.5 |
How to Choose the Right H-Beam Size
- For heavy-duty applications, such as bridges and skyscrapers, choose larger beams (300mm – 450mm) for maximum strength.
- For general construction, 100mm – 250mm beams offer good support while being cost-effective.
- For industrial machinery and shipbuilding, select custom-sized beams based on load requirements.
Advantages of Hot-Rolled H-Shaped Steel Over Other Profiles
| Feature | H-Beam (H-Shaped Steel) | I-Beam | Channel Steel |
| Flange Width | Wide and parallel | Narrow and sloped | Single-side flange |
| Weight Distribution | Even and efficient | Focused on center | Uneven |
| Load Capacity | High | Medium | Low |
| Application | Heavy-duty structures | Light-medium structures | Small-scale supports |
Why Choose H-Beams?
- Higher efficiency – Supports more weight with less material.
- Better stability – Reduces bending and deformation.
- Longer lifespan – Resists wear and corrosion, ensuring durability.
How to Purchase Hot-Rolled H-Shaped Steel
1. Select the Right Material
- Carbon Steel H-Beams – Standard for general construction.
