Bending irons

Steel curved bars are specialised bar profiles used for controlled changes of direction, curved runs and transitions in metal structures. They are an essential component in the construction of railings and handrails , in staircases, landing runs or in bespoke steel structures. Unlike straight bar stock, curved steel bars eliminate the need for time-consuming bending, forging or reworking.

Thanks to their pre-formed curvature, curved bars enable clean changes of direction without the need for additional heat treatment or mechanical forming. This reduces labour, processing time and ensures consistent, reproducible results – particularly important for high-quality balustrade systems or delicate handrail solutions.

Typical applications

• Handrail and balustrade systems with curves and changes in angle
• Staircases with curved runs
• Frame structures with offset elements
• Public and private metalwork projects with functional transitions
• Wrought iron designs with flowing lines

Curved bars are frequently used in combination with other bar materials, such as straight round tubes, square tubes, handrail components or connecting elements. They can be welded, bolted or mechanically fixed and, thanks to their pre-formed geometry, provide technically precise connection points.

Advantages of curved bars

• clean changes of direction without the need for subsequent bending
• reduced labour and manufacturing costs
• Uniform shape for reproducible results
• visually clean transitions and flowing lines in balustrade construction
• Easy to combine with other profiles and components

FeNau offers steel bending bars as a high-quality solution for demanding applications in metalwork and the building trades. Whether for classic stairs, modern balustrade systems or specialised custom structures – with bending bars, material usage can be planned more efficiently and installation carried out cleanly.

Tip: When selecting these, ensure you choose the correct bending radius and the appropriate alignment to achieve a perfect fit and a harmonious overall appearance . This allows functionality and design to be optimally combined.
