High-frequency welded H-beams
High-Precision High-Frequency Welded (HFW) H-Beams for Modern Steel Structures
Upgrade your construction efficiency with our premium High-Frequency Welded H-Beams. Engineered using advanced HFW technology, our beams offer superior dimensional accuracy, a high strength-to-weight ratio, and a smooth surface finish compared to traditional hot-rolled alternatives. As a dedicated HFW H-Beam manufacturer, we provide customizable sizes with thinner webs and wider flanges, perfect for light steel villas, industrial portals, and equipment frames. Our H-beams comply with international standards (ASTM, JIS, EN), ensuring structural integrity while reducing overall material costs. Build smarter, lighter, and faster with our precision-welded structural steel.
Overview of HFW Technology
In the evolving world of steel construction, High-Frequency Welded (HFW) H-Beams represent a significant leap in manufacturing efficiency. Unlike the conventional hot-rolling process, HFW H-beams are produced by welding steel strips (coils) through high-frequency current. This process allows for extremely fast production speeds and, more importantly, the ability to create thin-walled, high-strength sections that are not possible via hot-rolling.
Why Choose High-Frequency Welded H-Beams?
Our factory utilizes state-of-the-art automated welding lines to ensure every beam meets the most rigorous engineering tolerances.
Weight Optimization: HFW beams allow for a thinner web (down to 3.0mm), significantly reducing the total weight of the steel structure without sacrificing load-bearing capacity.
Dimensional Precision: With high-frequency welding, we achieve tighter tolerances in flange-to-web perpendicularity and overall linearity.
Customization Flexibility: Unlike hot-rolled beams limited by fixed molds, we can produce non-standard sizes tailored to your specific architectural requirements.
Superior Surface Quality: The use of cleaned steel strips results in a smoother surface, which is ideal for high-quality painting or galvanizing finishes.

We provide a wide range of specifications to meet global project demands:
Material Grades: Q235B, Q355B (S355JR), ASTM A36, ASTM A572, etc.
Web Thickness: 3.0mm – 12mm
Flange Thickness: 3.0mm – 25mm
Length: Standard 6m, 9m, 12m, or customized lengths to minimize on-site waste.
Compliance: ISO 9001 certified production, meeting GB/T 11263 and JIS G3192 standards.
Comparison: HFW vs. Hot-Rolled H-Beams
| Feature | HFW H-Beam | Hot-Rolled H-Beam |
| Web Thickness | Can be much thinner (lighter) | Generally thicker |
| Size Flexibility | Fully customizable | Limited to standard mold sizes |
| Lead Time | Faster for custom batches | Slower for non-standard orders |
| Internal Stress | Very low due to localized heating | High cooling stresses |
Primary Applications
