As a leading manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we are proud to offer the H-beam SS400, specifically designed for demanding applications such as bridge construction, gantry crane structures, and heavy machinery manufacturing. Our SS400 H-beam combines superior strength, excellent weldability, and reliable performance, making it the preferred choice for engineers and fabricators worldwide. With an annual export value between US$50 million and US$100 million, we ensure consistent quality and timely delivery to meet your project requirements.
Product Overview
The H-beam SS400 is a hot-rolled structural steel beam manufactured to JIS G3101 standard. Its unique H-shaped cross-section provides excellent load-bearing capacity, making it ideal for horizontal and vertical support in heavy-duty structures. Below are the key features and technical specifications:
| Parameter | Specification |
|---|---|
| Material | SS400 (Carbon Steel) |
| Standard | JIS G3101 |
| Yield Strength | ≥ 245 MPa (for thickness ≤ 16mm) |
| Tensile Strength | 400-510 MPa |
| Flange Width | 100mm – 900mm |
| Web Height | 100mm – 900mm |
| Web Thickness | 5mm – 30mm |
| Flange Thickness | 8mm – 40mm |
| Length | 6m – 12m (customizable) |
Key Features & Benefits
- High Load-Bearing Capacity: The H-shaped profile distributes weight evenly, reducing deflection and increasing structural stability.
- Excellent Weldability: SS400 steel has low carbon content, making it easy to weld without preheating or post-weld heat treatment.
- Cost-Effective: Compared to other structural steels, SS400 offers a balance of strength and affordability, reducing project costs.
- Versatile Applications: Suitable for bridges, gantry cranes, heavy machinery frames, building columns, and industrial platforms.
- Customizable Dimensions: We offer a wide range of sizes and can cut to specific lengths per your requirements.
- Surface Treatment Options: Available in black (mill finish), galvanized, or painted to resist corrosion in harsh environments.
- Consistent Quality: Our production is ISO9001 certified, ensuring strict quality control from raw material to final product.
Detailed Advantages for Heavy Machinery Manufacturing
In heavy machinery manufacturing, structural integrity is paramount. The H-beam SS400 provides:
- Resistance to Fatigue: The uniform cross-section reduces stress concentration points, extending the lifespan of crane rails and machine bases.
- Ease of Fabrication: Can be easily cut, drilled, and bolted, speeding up assembly on site.
- Compatibility with Other Components: Standard dimensions allow seamless integration with existing structures and accessories.
- Environmental Adaptability: Performs reliably in temperatures ranging from -20°C to 200°C, suitable for various climates.

Frequently Asked Questions (FAQ)
- What is the difference between SS400 and Q235B? SS400 is a Japanese standard (JIS G3101) while Q235B is Chinese (GB/T). Both have similar mechanical properties, but SS400 is more commonly used in international projects. Our SS400 meets JIS requirements.
- Can you provide H-beams with lengths longer than 12m? Yes, we can produce custom lengths up to 18m or more, subject to transportation feasibility. Please inquire for specific requirements.
- What surface treatment is recommended for outdoor bridge use? For outdoor applications, we recommend hot-dip galvanizing or epoxy coating to prevent rust. We can arrange these treatments per your request.
- How do you ensure the quality of the steel? We have a strict quality control system, including chemical composition analysis and mechanical property testing. Each batch comes with a mill test certificate.
- What is the minimum order quantity (MOQ) for SS400 H-beam? Our MOQ is typically 25 tons per size, but we can accept smaller orders for trial purposes. Contact us for details.
- Can you supply H-beams for offshore crane applications? Yes, our SS400 H-beam can be used for offshore cranes, but we recommend consulting with our engineers to select the appropriate grade and coating for marine environments.
- Do you offer cutting and drilling services? Yes, we provide custom cutting, drilling, and punching services to meet your fabrication needs. Please specify the dimensions and hole patterns.
- What is the typical lead time for an order? Lead time depends on quantity and size. For standard sizes, it is usually 15–30 days after confirmation of the order. For customized sizes, please allow 30–45 days.
