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 , staircases, landings and custom-designed steel structures. Unlike straight bar materials, curved 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 additional heat treatment or mechanical forming. This reduces labour, processing time and ensures consistent, reproducible results – particularly important for high-quality railing 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 offer technically precise connection points thanks to their pre-formed geometry.

Advantages of curved bars

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

FeNau offers steel bending irons as a high-quality solution for demanding applications in metal construction and the trades. Whether for classic stairs, modern railing systems or special custom constructions – with bending irons, material usage can be planned more efficiently and installation carried out cleanly.

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