Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner for high-quality structural steel profiles. As a newly established but rapidly growing steel supplier with an annual export value of US$50 Million – US$100 Million and a team of 51–100 experienced professionals, we are proud to present our S355JR H Beam Steel Profile ASTM A36 200x200mm to 400x400mm for Construction. This product combines the strength of European standard S355JR with the widely recognized ASTM A36 specification, offering exceptional load-bearing capacity and weldability for demanding construction projects. Our beams are manufactured under strict quality control and are backed by ISO9001 certification, ensuring consistent performance from Liaocheng, Shandong to your site.
Whether you are building high-rise structures, bridges, industrial plants, or infrastructure, our H beams provide the structural integrity you need. With sizes ranging from 200x200mm to 400x400mm and customizable lengths, we offer flexibility to meet diverse engineering requirements. The dual compliance with S355JR (yield strength 355 MPa) and ASTM A36 (minimum yield 250 MPa) gives you confidence in material reliability across different design codes.
Key Features & Technical Specifications
- Dual Standard Compliance: Meets both EN 10025-2 (S355JR) and ASTM A36, suitable for international projects.
- Wide Size Range: From 200x200mm (light duty) to 400x400mm (heavy duty) – one-stop solution for various spans.
- Excellent Mechanical Properties: S355JR offers minimum yield strength of 355 MPa, while ASTM A36 provides 250 MPa – ideal for structural frames.
- Superior Weldability: Low carbon equivalent ensures easy welding without preheating for most applications.
- Customizable Lengths: Standard lengths 6m, 9m, 12m, or cut to your exact requirements.
- Versatile Surface Options: Available in black (mill finish), painted (prime or color), or hot-dip galvanized for corrosion resistance.
- Precise Dimensional Tolerances: Compliant with EN 10034 or ASTM A6/A6M standards.
- Cost-Effective Solution: Optimized web/flange ratio reduces material waste while maintaining strength.
| Size (mm) | Flange Width (mm) | Web Thickness (mm) | Flange Thickness (mm) | Weight per Meter (kg/m) |
|---|---|---|---|---|
| H200x200 | 200 | 8 | 12 | 50.5 |
| H250x250 | 250 | 9 | 14 | 72.4 |
| H300x300 | 300 | 10 | 15 | 94.0 |
| H350x350 | 350 | 12 | 19 | 137.0 |
| H400x400 | 400 | 13 | 21 | 172.3 |
Mechanical Properties (Typical): For S355JR: Yield strength ≥ 355 MPa (for thickness ≤ 16mm), Tensile strength 470-630 MPa, Elongation ≥ 22%. For ASTM A36: Yield strength ≥ 250 MPa, Tensile strength 400-550 MPa, Elongation ≥ 20%. These properties ensure your structure can withstand heavy loads and dynamic stresses.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between S355JR and ASTM A36?
A: S355JR has a higher minimum yield strength (355 MPa vs 250 MPa for ASTM A36). Our H beam complies with both standards, meaning it can be used in projects where either specification is required. It offers extra strength for demanding applications. -
Q: Can you supply beams with lengths other than 12m?
A: Yes, we can cut to any length from 6m up to 12m, or even longer upon request. Custom lengths are available, and we can also supply pre-drilled or notched beams if needed. -
Q: What surface treatments are available?
A: Standard options include black (mill finish), one coat of primer paint, or hot-dip galvanized. We can also apply your specific color coating (e.g., RAL colors) for an additional cost. Please specify your requirement. -
Q: Do you provide Mill Test Certificates (MTC)?
A: Absolutely. Each shipment comes with a Mill Test Certificate conforming to EN 10204 or ASTM standards, confirming chemical composition and mechanical properties. Third-party inspection (e.g., SGS, BV) is also available upon request. -
Q: What are the tolerances for dimensions?
A: Our H beams are manufactured to EN 10034 (for S355JR) or ASTM A6/A6M (for A36). Typical tolerances: height ±2mm, flange width ±2mm, web thickness ±0.5mm, flange thickness ±0.5mm. Detailed tolerance charts are available on request. -
Q: How do you package the beams for sea freight?
A: Beams are bundled with steel straps, separated by wooden spacers to prevent damage. For galvanized or painted beams, we add protective wrapping. All bundles are marked with size, heat number, and quantity. We can also provide container loading plans to optimize space. -
Q: What is the typical lead time for an order?
A: For standard sizes (200x200 to 400x400) in black finish, lead time is 15-20 days after deposit. For customized lengths or surface treatment, it may be 20-30 days. Urgent orders can be discussed – we maintain buffer stock for popular sizes. -
Q: Do you offer samples before bulk order?
A: Yes, we can provide small samples (e.g., a 300mm long piece) for testing. The cost of sample and shipping is at client’s account, but it will be deducted from the first bulk order. Contact our sales team to arrange.
