Q355/Q235 Hot Rolled H-Shaped Steel

Product Details

As the “skeleton” of modern steel structure buildings, hot-rolled H-shaped steel, with their superior mechanical properties, high material utilization rate, and convenient construction characteristics, have become the preferred structural material for industrial and civil buildings, bridges, heavy machinery, and other fields. RUIISTEEL is committed to providing high-quality hot-rolled H-shaped steel that meet international standards, have stable quality, and are available in a full range of specifications.

Hot-rolled H-shaped steel is an economical and efficient steel material with a cross-sectional shape resembling the capital Latin letter “H”. They are produced by repeatedly rolling continuously cast billets at high temperatures using a universal rolling mill. The flanges (upper and lower sections) are perpendicular to the web (middle section), and the inner and outer sides of the flanges are usually parallel or nearly parallel.

Compared to welded H-beams, hot rolling is a one-time forming process, which brings significant advantages such as no weld seams, uniform performance, low residual stress, and good appearance quality.

Core Technical Specifications and Characteristics

1. Advantages in Cross-Sectional Properties

• High Section Modulus, Superior Load-Bearing Capacity: For the same weight, H-beams have a larger section modulus and radius of gyration than traditional I-beams, resulting in stronger resistance to bending, compression, and torsion.
• Optimized Strength-to-Weight Ratio: More economical structural design, enabling equal-strength design, effectively reducing structural weight and foundation costs while ensuring safety.
• Convenient Connection and Construction: Wide flanges with parallel inner and outer sides facilitate high-strength bolt connections or welding to other components (such as connecting plates), resulting in fast and efficient construction and installation.

2. Main Material Standards

Our products can be manufactured using the following internationally recognized standard steels according to customer requirements:

• Chinese Standards: Q235B, Q355B, Q355C, Q355D;
• American Standards: ASTM A36, ASTM A572 Gr.50, ASTM A992;
• European Standards: S235JR, S355JR, S355J0, S355J2;
• Japanese Standards: SS400, SM400, SM490, SM520;

Other international standards (such as JIS, DIN, BS, AS) can also be provided upon request.

3. Specification Range

We offer an extremely wide range of specifications to meet various engineering needs from light to heavy-duty:

Standard Series: Covering HW (wide flange), HM (medium flange), HN (narrow flange), etc.

Size Range:

• Section Height (H): 100mm to 1100mm
• Flange Width (B): 100mm to 450mm
• Web Thickness (tw): 4.5mm to 40mm
• Flange Thickness (tf): 7mm to 70mm

Length: Typically 6 meters to 18 meters, custom lengths available upon order.

Production Process and Quality Assurance

1. Advanced Production Process

We utilize a fully modernized production line encompassing continuous casting → heating → universal rolling → online straightening → cooling → finishing. The core universal rolling process simultaneously rolls both flanges and web, ensuring high dimensional accuracy, uniform internal structure, and stable performance.

2. Strict Quality Control

• Full-process monitoring: From steelmaking and continuous casting to rolling, key process parameters are fully automated and recorded.
• Comprehensive Testing: Each batch of products undergoes chemical composition analysis, mechanical property testing (tensile, bending, impact), and dimensional inspection to ensure compliance with standards.
• Authoritative Certification: The factory is ISO 9001 quality management system certified, and products can provide conformity certificates (Mill Certificates) and meet international certification requirements such as CE and JIS.

Core Application Areas

Hot-rolled H-shaped steel is used in almost all steel structure fields:

Building Structures: Main frame beams and columns of industrial plants, high-rise and super high-rise buildings, multi-functional warehousing and logistics centers, stadiums, and exhibition centers.

Bridge Engineering: Used for bridge piers, stiffening beams for long-span bridges, and bridge deck support structures.

Heavy Machinery: Load-bearing skeletons for port cranes, mining machinery, and large equipment supports.

Infrastructure: Transmission towers, offshore platform modules, and highway guardrail supports.

Vehicle Manufacturing: Chassis beams for railway freight cars and special transport vehicles.
