Hemaokang Steel (Shandong) Co., Ltd. is a specialized manufacturer and exporter of structural steel, headquartered in Liaocheng, Shandong, China. With an annual export value of US$50 million to US$100 million, we serve clients across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and other regions. Our H-Beam for Bridge Construction Gr50 A572 with 400x400x13x21 mm dimensions is designed to deliver outstanding structural performance and long-term reliability. Every beam is backed by a one-year warranty and we offer professional cutting services to fit your engineering requirements precisely.
Material and Manufacturing Standard
This H-beam is manufactured in accordance with ASTM A572/A572M, the standard specification for high-strength low-alloy columbium-vanadium structural steel. Grade 50 delivers a minimum yield strength of 50,000 psi (345 MPa), making it highly suitable for load-bearing bridge members. Our production process includes strict control of chemical composition, controlled rolling, and comprehensive mechanical testing to ensure uniform strength, good toughness, and excellent weldability. These properties are essential for bridge girders, trusses, and other critical structural elements that must endure heavy static and dynamic loads.
Dimensional Specifications
The profile 400x400x13x21 mm precisely defines the geometry of the H-beam:
| Parameter | Value |
| Web Height | 400 mm |
| Flange Width | 400 mm |
| Web Thickness | 13 mm |
| Flange Thickness | 21 mm |
| Material Grade | A572 Gr50 |
| Standard Length | 6m – 18m (customizable) |
| Warranty | 1 Year |
Key Features and Advantages
- High Load-Bearing Capacity: The wide flange and relatively thick web provide a large moment of inertia and high section modulus, enabling the beam to resist bending, torsion, and shear forces in heavy bridge structures.
- Excellent Stability: A572 Gr50 steel maintains consistent mechanical properties, reducing the risk of deformation and ensuring safe performance under repeated traffic loads and environmental stress.
- Superior Weldability: The optimized chemistry allows for reliable welding using conventional methods, simplifying fabrication and on-site assembly.
- Versatile Use: Suitable for bridge main girders, cross beams, pier caps, highway overpasses, and industrial steel frames.
- Weather Resistance: When properly painted or galvanized, this H-beam can withstand atmospheric corrosion and extend the service life of the structure.
- Customizable Length and Cutting: We can cut the beam to your exact length, add holes, chamfers, or other detailing based on your shop drawings.
Benefits for Bridge Construction Projects
- Reduces steel tonnage and overall project cost by using higher yield strength while maintaining structural integrity.
- Accelerates construction schedules because the H-beam is straight, dimensionally accurate, and easy to connect with other steel members.
- Simplifies quality control through mill test certificates and traceable heat numbers provided with every shipment.
- Enables engineers to design slimmer members, increasing aesthetic appeal and usable space in bridge architecture.
- Supports sustainable construction because steel is recyclable and can be reused after decommissioning.
Customization and Cutting Service
We understand that every bridge project has unique dimensions and connection requirements. Our advanced cutting service provides precise cutting to any specified length, with cutting tolerances that meet international standards. Whether you need simple straight cuts, beveled edges, or drilled holes for bolted connections, our workshop can accommodate. We also offer additional optional services such as surface treatment (shot blasting, painting), packing according to ocean transport standards, and third-party inspection upon request. This flexible approach ensures that you receive parts that are ready for installation, saving time and reducing site work.
Quality Assurance and Warranty
All H-beams are supplied under an ISO9001 certified quality management system. Each batch is subject to rigorous inspections including tensile testing, impact testing, chemical analysis, and dimensional verification. We strictly follow the requirements of ASTM A572/A572M to ensure the material grade and dimensions are fully traceable. Our one-year warranty covers the product against material defects and manufacturing issues, giving you complete confidence. If you require additional documentation, such as mill certificates or EN 10204 type 3.1, we can provide it upon request.
Applications
This H-beam is widely used in highway bridges, railway bridges, pedestrian bridges, steel trestles, and temporary bridge structures. Its robust section is also ideal for heavy industrial plants, mining platforms, and large-scale steel frame construction. The combination of strength, weldability, and dimensional accuracy makes it a trusted choice for general contractors, fabricators, and engineering firms worldwide.

We welcome your inquiry, and our engineers are ready to support your project with technical advice, cutting details, and competitive quotations.
Frequently Asked Questions
Q1: What is the difference between H-beam and I-beam for bridge construction?
A: H-beams have wider flanges and a more uniform cross-section, offering better load distribution and stability. This makes H-beams more suitable for heavy bridge structures where bending and torsion resistance are critical.
Q2: How does the cutting service work?
A: You can provide your required lengths and cutting details (such as bevels or holes). We will cut the H-beams accordingly and ensure the finished dimensions match your drawings within standard tolerances.
Q3: Can you supply mill test certificates?
A: Yes, mill test certificates with chemical composition and mechanical properties are available. They can be sent before shipment for your approval.
Q4: What length options are available?
A: Standard lengths are typically 6m, 9m, 12m, and 18m. We also supply custom lengths according to your project needs, subject to transportation constraints.
Q5: Is the A572 Gr50 H-beam weldable?
A: Yes, A572 Gr50 is designed for welding. Proper preheating and welding procedures are recommended for thicker sections to achieve optimum joint quality.
Q6: What is the delivery time?
A: For standard profiles, delivery usually takes 10-20 days after order confirmation. For custom cutting or special sizes, lead time may be longer, but we will provide a precise schedule to your schedule.
Q7: Can you provide surface treatment like galvanizing or painting?
A: Yes, we offer optional shot blasting, painted, hot-dip galvanized, and other protective coatings. Please specify the standard you require (e.g., ASTM, BS, EN) in your inquiry.
Q8: What payment terms do you accept?
A: We commonly accept T/T, L/C at sight, and other flexible terms. Our sales team will be happy to discuss the best option for your order size and destination.
