Designed for prefabricated projects, this H beam pairs Q355b (355MPa yield) and S355 (355MPa yield) grades, with key sizes 300×150mm and 400×200mm (web thickness 7–22mm, flange thickness 11–35mm) and lengths 6–12m. Hot-dip galvanizing provides long-lasting corrosion protection for outdoor storage and warehouse frames. The high-strength material supports spans up to 20m (with bracing), creating open, flexible interiors. It offers excellent weldability and workability, enabling fast prefabrication and on-site assembly. Lightweight yet load-bearing, it lowers construction costs and maintenance needs. The recyclable steel aligns with eco-friendly practices, making it a reliable choice for commercial and industrial prefabricated buildings.

Q235B Q355B Hot Rolled Galvanized H Beam 150X75 200X100 Structural Steel

 

This H beam offers dual material grades (Q235B/Q355B) with core sizes 150×75mm and 200×100mm, plus custom options (height×flange width: 100×50mm–1000×300mm) and lengths 6–12m. Hot rolling ensures uniform grain structure, while hot-dip galvanizing meets EN ISO 1461 for superior corrosion resistance. Q235B (yield strength 235MPa) excels in weldability for general structures, while Q355B (355MPa yield strength) delivers high load-bearing capacity for heavy-duty use. The balanced cross-section (web thickness 5–22mm, flange thickness 8–45mm) resists buckling, making it ideal for warehouses and factory frames. Lightweight yet durable, it reduces transportation/installation costs and requires minimal maintenance, balancing affordability and performance for industrial and commercial projects.

 

 

 

 

ASTM A36 SS400 150X150 Hot Rolled H Beam Mild Steel Structural Sections

 

Compliant with ASTM A36 and JIS SS400 standards, this H beam features a popular 150×150mm size (web thickness 7mm, flange thickness 10mm) and extends to 900×300mm, with lengths 6–14m. Mild steel composition ensures excellent ductility (elongation ≥21%) and weldability, compatible with MIG/TIG welding without preheating. ASTM A36 (250MPa yield strength) and SS400 (235MPa yield strength) offer reliable structural stability for bridges, mezzanines, and building frames. Hot rolling enhances surface finish and material density, reducing fabrication time. Cost-effective and widely available, it supports long spans, eliminates intermediate columns, and aligns with eco-friendly practices via 100% recyclability.

S235jr S355jr Galvanized H Beam 250X125 300X150 Hot Rolled Structural Steel

 

Adhering to EN 10025 standards, this H beam provides S235jr (235MPa yield) and S355jr (355MPa yield) grades, with key sizes 250×125mm and 300×150mm (web thickness 6–20mm, flange thickness 10–35mm) and lengths 6–12m. Hot-dip galvanizing protects against moisture/rust, extending service life in outdoor/harsh environments. The wide flange design boosts load distribution, making it suitable for prefabricated workshops and storage frames. It offers excellent impact resistance (even at -20℃) and workability, allowing easy cutting, drilling, and assembly. Lightweight yet robust, it lowers logistics costs, accelerates construction, and maintains structural integrity under dynamic loads-ideal for industrial and infrastructure projects.

 

 

 

 

HEA/HEB/IPE 150X150 H Beam Q235B Q345 Hot Rolled Mild Steel Sections

 

This versatile H beam covers HEA (light), HEB (heavy), and IPE (European) profiles, with a core 150×150mm size and ranges 100×50mm–800×300mm, lengths 6–12m. Q235B and Q345 grades cater to diverse needs: Q235B for cost-sensitive general structures, Q345 (345MPa yield) for heavy-duty supports. Hot rolling ensures consistent cross-section dimensions, critical for modular assembly. Mild steel delivers good toughness and corrosion resistance (with optional galvanizing). The standardized profiles simplify logistics and fabrication, compatible with standard connectors. It's perfect for factory workshops, commercial buildings, and residential steel frames, balancing flexibility, performance, and affordability.
