HEA - HEB Wide Flange Bending
Ankay Büküm bends heavy HEA and HEB H-beams into curved forms for large structures, bridges, and tunnels.
What Is HEA-HEB Wide Flange Bending?
HEA-HEB bending is a structural steel forming process in which wide-flange heavy H-section profiles are shaped into circular, elliptical, or custom curved forms on profile bending machines. HEA (light series) and HEB (standard series) profiles are among the heaviest load-bearing elements of steel structures, and their bending requires specialized capacity and engineering knowledge. At Ankay Büküm in Ankara's Ostim Industrial District, we bend heavy profiles from HEA 100 to HEA 400 and HEB 100 to HEB 300, serving bridge, tunnel, and large-scale steel structure projects.
Application Areas
- Bridges and Viaducts: Main load-bearing girders for curved bridges, gradient viaduct elements, and pedestrian crossing structures
- Tunnel Construction: Metro tunnel support frames, highway tunnel steel linings, and TBM exit portal structures
- Large Steel Structures: Curved load-bearing frames for stadiums, arenas, and convention centers requiring 50-meter and above spans
- Industrial Facilities: Heavy-duty crane beams, steel platform supports, and factory main structural frames
- Energy Sector: Wind turbine tower internal structural rings, nuclear facility protection structures, and thermal plant steel constructions
Technical Capacity and Specifications
Our facility bends HEA 100 to HEA 400 light series and HEB 100 to HEB 300 standard series H-profiles. Bending is available in both easy-axis (perpendicular to flange) and hard-axis (parallel to flange) orientations. Minimum bending radius for HEA 200 is approximately 5 meters, for HEB 300 approximately 12-15 meters. Heat-assisted bending is used for heavy profiles to preserve material properties. We process S235JR, S355J2, and S460 grade steels.
Quality Assurance
HEA-HEB bending is performed under our EN 1090-2 EXC3 class production capability. Post-bending inspections include detailed flange deformation, web waviness, and dimensional tolerance checks. Ultrasonic and magnetic particle inspections ensure structural integrity, and all pieces are delivered with material certificates (EN 10204 3.1).
Ankay Büküm is among the leading service providers in Ankara Ostim for HEA and HEB profile bending. For curved load-bearing profile needs of your bridge, tunnel, stadium, and heavy industry projects, we stand ready with over 30 years of experience and specially equipped facilities. Share your technical requirements and let us determine the best solution for your project together.
Frequently Asked Questions
What is HEA-HEB bending and what is it used for?
HEA-HEB bending is the process of curving wide-flange heavy H-section steel profiles into arched or circular forms. It is used for bridge main girders, tunnel support frames, and arched elements of large-span steel structures.
What profile sizes can be bent?
HEA 100 to HEA 400 and HEB 100 to HEB 300 H-profiles are processed. Both easy-axis and hard-axis bending are available.
What is Ankay Büküm's HEA-HEB bending capacity?
Profiles up to HEA 400 and HEB 300 are processed. Minimum bending radius is ~5 m for HEA 200 and ~12-15 m for HEB 300. Heat-assisted bending is used for heavy profiles.
What products are made with HEA-HEB bending?
Curved bridge main girders, tunnel support frames, stadium roof supports, heavy crane beams, and large-span arched steel structures are manufactured.
How are pricing and delivery times determined?
Pricing is project-based according to profile size, bending radius, material grade, and quantity. Heavy profile projects average 7-15 business days delivery. Contact us for technical consultation.
