When it comes to high-quality structural steel for construction, industrial projects, and fabrication, H beam steel JIS G3101 SS400 grade stands out as a trusted choice. Manufactured according to the Japanese Industrial Standard JIS G3101, SS400 grade steel combines excellent mechanical properties, consistent performance, and versatility, making it suitable for a wide range of building and engineering applications. Muchang as a trusted supplier of H beam steel, ensures every H beam meets strict quality and dimensional requirements, providing engineers and project managers with confidence for structural integrity.

What is H Beam Steel JIS G3101 SS400 Grade?

H beam steel, also known as wide-flange steel, is characterized by its “H” shaped cross-section, which provides high load-bearing capacity and rigidity. The JIS G3101 SS400 grade is a standard structural steel widely used in Japan and internationally. It is designed for applications where moderate strength and weldability are required, offering a balance between cost-efficiency and structural performance.

Key properties of SS400 H beam steel:

• Yield strength: ~235 MPa

• Tensile strength: 400–510 MPa

• Good weldability and machinability

• Suitable for bolted, riveted, and welded connections

Muchang ensures that all H beams produced comply with dimensional tolerances and surface quality standards, guaranteeing smooth integration into construction and fabrication projects.

Applications of SS400 H Beam Steel

H beam steel JIS G3101 SS400 grade is a versatile material used in a variety of structural applications:

1. Commercial and Industrial Buildings
   From warehouses to office buildings, SS400 H beams provide a stable framework capable of supporting floors, walls, and roofing systems.

2. Bridges and Infrastructure
   For small to medium-span bridges and pedestrian overpasses, SS400 H beams offer reliable load-bearing capacity with easy fabrication and installation.

3. Factories and Workshops
   The steel’s uniform strength and flexibility allow for the construction of heavy-duty factory frameworks, cranes, and mezzanine floors.

4. Residential Projects
   Increasingly, H beam steel is used in residential projects for its strength and aesthetic versatility, enabling open floor plans with fewer supporting columns.

5. Engineering Structures
   Utility poles, storage racks, and structural supports for machinery often rely on SS400 H beam steel for durability and cost-effectiveness.

Why Choose JIS G3101 SS400 Grade?

1. Standardized Quality
The JIS G3101 standard specifies chemical composition, mechanical properties, and permissible tolerances, ensuring consistent quality across batches.

2. Cost-Effective Solution
SS400 grade steel offers a balance between strength and cost, making it ideal for large-scale projects where budget efficiency matters.

3. Excellent Workability
With good weldability, machinability, and formability, SS400 H beams are suitable for cutting, drilling, and welding without compromising performance.

4. Reliable Performance
Even under moderate loads, SS400 H beams maintain structural integrity, providing long-term reliability for buildings and infrastructure.
