U-Bent Rebar, also known as U-bar, U-shaped reinforcing bar, or bent anchor bar, is a prefabricated reinforcing element bent into a 'U' configuration for efficient placement in structural reinforcement zones. Typically made from HRB400 or HRB500 deformed steel bars, U-bars are widely used in concrete beams, wall connections, foundation edges, and tie reinforcements. They reduce jobsite bending work and ensure uniform shape and precision. Yoshine’s U-Bent Rebar products conform to GB1499.2, BS4449, and ASTM A615 standards and are available in various diameters, leg lengths, and bend angles.
Bar Diameter (mm) | Leg Length (mm) | Bend Angle (°) | Steel Grade |
10 | 100–300 | 90 / 135 | HRB400 |
12 | 100–500 | 90 / 135 / 180 | HRB400 / HRB500 |
16 | 200–600 | 135 / 180 | HRB500 |
20 | 300–700 | 135 | HRB500 |
25 | Custom | Custom | HRB500 |
Yoshine provides custom bending services for U-bars based on your construction drawings or bending schedules. Our advanced bending machines ensure consistent leg lengths, angles, and tolerances for accurate and efficient placement. We also offer bundled labeling, sorting, and quantity calculation services to support project-specific reinforcement planning.
• Made from high-strength deformed bars (HRB400/HRB500) for superior reinforcement.
• Pre-bent U-shape improves placement speed and accuracy.
• Available in multiple diameters, leg lengths, and bend angles.
• Ideal for beam stirrups, tie reinforcement, and foundation edges.
• Meets GB1499.2, BS4449, ASTM A615, and ISO 9001 standards.
Yoshine manufactures U-Bent Rebar under strict ISO 9001 quality control systems. Each unit is bent using calibrated machines and verified for angle accuracy, length tolerance, and surface condition. Our products meet international standards including GB1499.2 (China), BS4449 (UK), and ASTM A615 (USA), and are supported by full traceability and inspection documentation.
✅ Time-Saving on Site
Factory-bent U-bars reduce on-site labor by eliminating manual bar bending, allowing faster installation and less rework.
✅ Precision & Consistency
Machine-bent bars ensure uniform leg lengths and angles, improving structural accuracy and compliance with design specifications.
✅ Versatile for Multiple Structures
U-bars are widely used in foundations, beams, tie zones, precast walls, and connection edges across many project types.
✅ Strong Anchorage & Structural Bonding
Bent ends provide mechanical anchorage within concrete, enhancing bond strength and load transfer in structural members.
✅ Global Export Capability
Yoshine’s U-Bent Rebar is suitable for export and use in international infrastructure projects with reliable documentation and compliance.
