S235 S275 S355 Hea Ipe Ub Mild Steel H Beam for Construction

As a core structural component widely applied in modern construction and engineering projects, our S235, S275 and S355 grade mild steel H beams, covering HEA, IPE and Ub standard profiles, are manufactured in strict compliance with European and international steel structure specifications, integrating superior mechanical properties, stable dimensional accuracy and excellent processing adaptability. Tailored for diversified construction scenarios, these products deliver reliable load-bearing performance and long-term structural stability, making them the preferred choice for industrial and civil construction, bridge engineering, steel structure fabrication and infrastructure construction.

Material Grades and Core Mechanical Properties

Our H beams adopt three mainstream high-quality mild steel grades, each featuring targeted mechanical indicators to meet different load-bearing and service requirements, fully complying with EN 10025-2 standard for hot-rolled structural steels:

S235 Grade: A general-purpose mild structural steel with a minimum yield strength of 235MPa, featuring outstanding ductility, weldability and cold forming performance. It is suitable for light-load structural parts, secondary framing and non-critical support components in ordinary buildings, balancing cost efficiency and basic structural reliability.

S275 Grade: A medium-strength structural steel with enhanced mechanical properties, positioned between S235 and S355. With a minimum yield strength of 275MPa, it offers better rigidity and load capacity than S235, ideal for medium-load beams, columns and supporting structures in industrial workshops, commercial buildings and general infrastructure, adapting to conventional construction stress conditions.

S355 Grade: A high-strength low-alloy structural steel with a minimum yield strength of 355MPa, boasting exceptional tensile strength, impact resistance and fatigue durability. It excels in heavy-load, high-stress and harsh-service environments, widely used in high-rise buildings, large-span bridges, heavy industrial plants and critical load-bearing frameworks, ensuring structural safety under extreme working conditions.

Standard Profiles and Dimensional Specifications

We provide a complete range of standardized H beam profiles to match diverse engineering design needs, covering European standard HEA series, IPE I-beam series and British standard Ub series, with uniform cross-section dimensions, smooth surface and precise tolerances to facilitate on-site cutting, welding, drilling and assembly:

HEA Series: European standard wide-flange H beams, characterized by parallel flanges, moderate cross-section dimensions and uniform stress distribution. They feature strong bending resistance and lateral stability, suitable for main load-bearing columns and beams in steel structures, realizing efficient force transmission and optimized structural layout.

IPE Series: European standard I-beams with a classic I-shaped cross-section, lightweight yet high-strength, focusing on vertical load-bearing capacity. They are widely used in floor beams, roof trusses and secondary support structures, reducing dead weight while ensuring structural rigidity, effectively lowering overall project material consumption.

Ub Series: British standard universal H beams, designed in line with UK construction specifications, featuring standardized dimensions and high compatibility with British engineering systems. They are widely applied in construction projects following British standards, offering stable performance and seamless docking with supporting components.

Product Advantages and Construction Applicability

Our mild steel H beams are produced via advanced hot-rolling technology, with refined internal structure, no internal defects and consistent performance across the entire profile. The uniform cross-section design optimizes the strength-to-weight ratio, enabling higher load capacity with lower material usage, which effectively reduces construction costs and shortens installation cycles. Excellent weldability and machinability allow for flexible processing and on-site modification, adapting to complex structural designs and customized construction requirements.

With superior corrosion resistance foundation and durable structural performance, these H beams maintain stable mechanical properties in conventional construction environments, prolonging service life and reducing later maintenance costs. Whether for residential construction, commercial complex projects, industrial workshops, bridge engineering or steel structure prefabrication, our S235, S275, S355 HEA, IPE and Ub mild steel H beams provide reliable, efficient and cost-effective structural solutions for global construction projects.
