Steel perforated strips and bars

Steel perforated channels form the practical basis for flexible metal structures – wherever components need to be quickly bolted together, aligned or extended at a later date. In the field of bar stock , perforated channels are among the most versatile solutions for metalwork , railing and fencing construction , frame structures, as well as workshop and assembly work. At FeNau , you’ll find various designs of perforated strips, tailored to different applications and fastening scenarios.

The advantage: thanks to the pre-drilled holes, you save processing time, get defined connection points and can plan structures accurately. Depending on the sub-category, perforated strips differ primarily in profile shape and type of hole – and thus in stability, appearance and assembly options.

Subcategories at a glance – differences & applications

Square perforated strips

Square perforated strips offer high stability and a clean, technical appearance. Ideal for frames, grilles, structures and wherever a dimensionally stable connection is required.

Round perforated strips

Round perforated strips are particularly suitable for applications where a harmonious appearance or a lighter structure is desired – for example, in decorative structures, balustrade elements or flexible fixing solutions.

Perforated strips with single-sided holes

This variant is ideal when fastenings are to be made specifically from one side only. Perfect for mounting points where the opposite side is to remain visible or is structurally inaccessible.

Perforated strips with through-holes

Through-holes allow for classic screw connections through the material – stable, detachable and particularly suitable for modular constructions that may need to be adjusted or extended at a later date.

Punched bars

Punched perforated bars feature uniform hole patterns and are ideal for mass production, standardised assemblies and rapid assembly processes. Ideal when repeatability and speed are paramount.

Typical applications

Modular frame and rack constructions in metalworking
Railings, fences and grilles with flexible fixing points
Workshop and assembly work requiring variable alignment
Jig and fixture construction and technical structures with detachable connections

Selection tip

For load-bearing or particularly stable structures, the square-section design is usually recommended. If the connection needs to be flexible and easy to assemble, through-holes are often the best choice. For standardised work and recurring projects, punched bars offer a significant efficiency advantage.
