Hemaokang Steel (Shandong) Co., Ltd. proudly presents the ASTM A572 Grade 50 Q235B Structural H Beam 200x200x8x12, a premium-grade steel profile engineered for demanding structural applications. As a manufacturer located in Liaocheng, Shandong, we combine advanced production capabilities with rigorous quality control to deliver H beams that meet international standards. This product is specifically designed for steel frame construction, offering excellent load-bearing capacity, weldability, and dimensional accuracy for projects requiring reliable structural integrity.
Our H beam steel is hot-rolled from selected raw materials, ensuring uniform mechanical properties and consistent cross-section dimensions. Whether you are building industrial plants, high-rise buildings, bridges, or prefabricated structures, this H beam delivers the strength and durability needed to support heavy loads while providing ease of fabrication and installation.
Key Features and Technical Specifications
- Material Grade: ASTM A572 Grade 50 (high-strength low-alloy columbium-vanadium steel) or Q235B (Chinese standard carbon steel) – both available to suit various project requirements.
- Nominal Dimensions: 200 mm height × 200 mm width × 8 mm web thickness × 12 mm flange thickness – a balanced profile ideal for columns and beams.
- Length: Standardly supplied in 6m, 9m, or 12m lengths; customized cutting and drilling are available upon request.
- Surface Finish: Black natural (mill finish), painted (red oxide, anti-rust), hot-dip galvanized, or other coatings to enhance corrosion resistance and service life.
- Tolerance: Manufactured in compliance with ASTM A6/A6M tolerances, ensuring precise geometry for seamless connections.
- Inspection Documents: Each batch is accompanied by a Mill Test Report providing chemical composition and mechanical properties for full traceability.
- Processing Services: Cutting, drilling, welding, and assembling services are available to reduce on-site work.

Frequently Asked Questions (FAQ)
Q1: What is the difference between ASTM A572 Grade 50 and Q235B?
A1: ASTM A572 Grade 50 is a high-strength low-alloy steel with a minimum yield strength of 345 MPa, suitable for structures requiring higher load-bearing capacity. Q235B is a Chinese standard carbon steel with a yield strength of 235 MPa, commonly used in general building frames. We can supply either grade based on your engineering design.
Q2: Do you provide a Mill Test Report?
A2: Yes, every shipment includes a Mill Test Report that certifies the chemical composition and mechanical properties of the H beam material. The report is issued by the steel mill and is available for all batches.
Q3: Can you cut the H beam to custom lengths?
A3: Absolutely. We provide cutting services to your specified lengths, with precision tolerances maintained. Additional processing such as drilling holes or notching can also be done based on your drawings.
Q4: What surface treatments are available?
A4: We offer black (mill finish), painted (red oxide, antirust paint), hot-dip galvanized, and other anti-corrosion coatings. For coastal or highly humid environments, hot-dip galvanizing is recommended to extend service life.
Q5: What is the maximum length you can produce?
A5: Our standard lengths are 6m, 9m, and 12m. For special projects, we can also supply up to 14m depending on transportation conditions and availability. Custom lengths can be produced to order.
Q6: How do you pack the H beams for export?
A6: H beams are bundled with steel strapping and wrapped with waterproof material to prevent corrosion and damage during transit. Loose loading is available for large-size orders. Each bundle is clearly marked with lot number and specifications.
Q7: Can you provide third-party inspection?
A7: Yes, we can arrange third-party inspection by agencies such as SGS, BV, or TUV if required. There will be an additional cost, and we will coordinate the inspection schedule with your representative.
Q8: What are your payment terms?
A8: We accept various payment terms, including T/T, L/C, and other commonly used international trade methods. The terms can be negotiated based on order value and your company's purchasing requirements.
