Light Carbon Steel I Beam

Optimized Structural Efficiency
Engineered to maximize the strength-to-weight ratio, our light I beams reduce material mass by up to 15% compared to standard sections. This design lowers freight costs, simplifies lifting, and decreases foundation requirements without compromising bending resistance or load distribution.
Certified Mechanical Performance
We supply verified carbon steel grades (ASTM A36, A572, S355JR, SS400) with strictly controlled chemical compositions and guaranteed yield/tensile strengths. Every batch is tested to meet international standards, ensuring reliable structural integrity for demanding applications.
Superior Fabrication & Weldability
Low carbon equivalent (CEV) values enable crack-free welding, while consistent dimensions allow clean cutting, drilling, and cold forming. This reduces on-site processing time and minimizes rework, accelerating project timelines.
Cost-Effective Value Delivery
By combining lightweight design, in-house fabrication services (cutting, drilling, galvanizing), and strict quality control, JNXYH helps customers reduce total project costs. Our 200,000+ ton annual capacity ensures stable pricing and reliable supply for large-scale or long-term contracts. 

Quality is engineered into every beam through a rigorous, traceable process.

Raw Material Verification: Spectrometer testing for chemical composition before rolling.
In-Process Monitoring: Laser measurement tools guarantee consistent dimensions.
Final Testing: Ultrasonic testing (UT), tensile testing, and Charpy V-Notch impact testing.
Documentation: Comprehensive Mill Test Certificates (MTC) with full 5-year traceability.  

Reduce local processing costs with in-house fabrication:

Precision Cutting: Saw/plasma cutting to exact lengths (±1mm tolerance).
Drilling & Punching: CNC hole punching for connection plates.
Surface Treatment: Custom painting or hot-dip galvanizing.
Export Packaging: Seaworthy steel-strapped bundles with waterproof wrapping.  

Proven Track Record: 15+ years exporting to North America, Europe, Southeast Asia, and the Middle East.
Stable Supply: 200,000+ tons annual capacity supports large-scale projects.
Engineering Support: Cross-standard grade equivalency guidance and BIM model support.
Transparent Terms: Clear MOQ policies and dedicated post-sale account managers.
