The A36 / Q235 / Gr50 Carbon Steel H-Beam is a high-strength structural section widely used in industrial, commercial, and infrastructure projects. Manufactured under ASTM, JIS, EN10025, and GB standards, these H-beams provide reliable bending resistance, excellent weldability, and consistent mechanical performance.
With available lengths up to 12 meters and thickness ranging from 4.5 mm to 17 mm, this product is suitable for heavy-duty structural systems and long-span building frameworks.
Key Features and Benefits
High Load-Bearing Capacity
The wide flange structure allows an increased section modulus, delivering 12–28% higher bending resistance than conventional I-beams of similar weight.
Excellent Weldability and Formability
Grades such as Q235 and A36 have low carbon content, enabling stable welding performance and smooth fabrication during construction.
Reduced Material Consumption
Under the same loading conditions, H-beams can reduce steel usage by 10–15%, lowering overall project material costs.
Improved Structural Stability
Gr50 and S355 equivalent grades provide higher strength and toughness, offering better vibration resistance and improved performance in seismic regions.
Durable Surface Options
Bare, black, galvanized, painted, or coated surfaces are available to match different environmental conditions and project requirements.
Technical Advantages
Optimized Structural Geometry
The parallel flange design and uniform thickness ensure better alignment, easier assembly, and improved load distribution across beams and columns.
Advanced Manufacturing
Hot-rolled production guarantees a uniform internal structure, stable mechanical properties, and consistent dimensional accuracy.
International Standard Compatibility
Equivalent materials include ASTM A36/Gr50, EN S235JR/S355JR, JIS SS400–SS540, and GB Q235–Q420, making it suitable for cross-border engineering specifications.
Application Fields
Construction and Building Structures
Widely used in steel-framed buildings, warehouses, workshops, and multistory structures where high load-bearing capacity is required.
Infrastructure Engineering
Suitable for bridges, platforms, tunnels, rail systems, and metro construction due to its stability and strength.
Industrial Manufacturing
Used for machinery bases, industrial equipment frames, shipbuilding components, and heavy machine structures.
Architectural and Fabrication Projects
Applied in canopies, steel frameworks, structural reinforcements, and customized fabrication solutions.
