‌

The S275JR I-Beam is a cornerstone of modern structural engineering. According to the European standard EN 10025-2, "S" denotes its classification as structural steel, while "275" represents a minimum yield strength of 275 MPa. The "JR" suffix indicates its impact toughness-tested at 27J at room temperature (+20°C).

 

S275JR I-Beam

 

As a premier manufacturer, we provide a comprehensive range of I-beams (IPE80–IPE750) that leverage the superior weldability and formability of S275JR carbon steel, making it the ideal choice for load-bearing structures that require a high strength-to-weight ratio.

 

 

Our production line covers standard and customized sizes to meet diverse engineering requirements.

The low carbon and high manganese content of S275JR ensure excellent welding performance without the need for extensive preheating.

Ladle Analysis (% max)

Steel Grade	C	Mn	Si	P	S	N	Cu	CEV
S275JR	0.21	1.50	-	0.040	0.040	0.012	0.55	0.40
S275J0	0.18	1.50	-	0.035	0.035	0.012	0.55	0.40
S275J2	0.18	1.50	-	0.030	0.030	-	0.55	0.40

Note: S275J0 and S275J2 offer higher toughness at 0°C and -20°C respectively, suitable for extreme environments.

 

 

S275JR I-Beams exhibit consistent mechanical performance across different thicknesses.

Property	Nominal Thickness (mm)	Typical Value
Min. Yield Strength (Reh)	≤ 16mm	275 MPa
	16mm < t ≤ 40mm	265 MPa
Tensile Strength (Rm)	3mm < t ≤ 100mm	410 - 560 MPa
Min. Elongation (A%)	3mm < t ≤ 40mm	23%
Impact Energy (Charpy)	Temperature: +20°C	27 Joules (JR)

 

 

Quick Erection: I-beams are designed for fast assembly in steel framing systems, significantly reducing project timelines.

• Weight Optimization: The high tensile strength allows for lighter sections to bear heavier loads compared to lower grades like S235, optimizing material costs.
• Vibration Resistance: Structural steel frames provide strong resistance to sudden shocks and vibrations, essential for bridges and industrial machinery.
• Versatile Fabrication: Readily weldable and formable, these beams can be easily cut, drilled, and bolted.

 

 

Our S275JR beams comply with international standards, making them interchangeable with the following global grades:

• Germany (DIN): St44-2
• USA (ASTM): A529 / A36 (Slight variations)
• Japan (JIS): SS400
• China (GB): Q275Z / Q235B
• India (IS): IS 2062 E300 A
• International (ISO): E275B

 

 

S275JR I-Beams are the "backbone" of numerous high-strength applications:

• Infrastructure: Highway bridges, transmission towers, and railway wagons.
• Marine & Offshore: Oil and gas platforms, offshore structures, and dolphins.
• Heavy Machinery: Excavators, bulldozers, cranes, and forestry machines.
• Storage & Transport: Pressure vessels, storage tanks, and freight cars.
• Energy: Penstocks and building structures for power plants.

 

 

Partnering with a leading China manufacturer ensures you get the best value and reliability.

• Standard Sizes in Stock: IPE80 to IPE400 available for immediate shipment.
• Quality Certification: All products come with MTC (Mill Test Certificate) according to EN 10204 3.1, plus CE, ISO, and BV certificates.
