Flat bar

Flat steel bars (S235JR) – versatile bar stock for metal construction and design

Flat bars are among the most important basic sections in metal construction: they are straight, dimensionally stable and can be used in countless projects as load-bearing or decorative elements. The FeNau range includes flat bars made from S235JR steel (uncoated) in various dimensions and finishes – from classic structural flat steel to decorative profiles with a textured finish. This makes flat steel suitable for both functional structures and visually sophisticated wrought iron and fencing projects.

Areas of application

Flat bars are typically used wherever you need robust, straight-lined profiles for assembling, joining or reinforcing. Thanks to the wide range of shapes and finishes available, flat bars can also be specifically used as design elements.

• Balustrades & handrails: as infill bars, cross-braces or decorative accent strips – e.g. grooved profiles for a more premium look.
• Fence & gate construction: as frame, decorative or reinforcing elements; textured variants enhance the classic wrought-iron look.
• General metalwork: as a universal profile, connecting plate, web or structural flat steel for stable structures.
• Mass production & jig and fixture construction: depending on the design, also as defined, repeatable components in the assembly of sub-assemblies.

Material: S235JR (uncoated) – tried and tested for construction & further processing

The flat bars in the FeNau range are supplied as S235JR steel in an uncoated finish. For many applications in metal construction, this is precisely the advantage: the raw material is intended directly for further processing and can be flexibly adapted to project requirements (e.g. cutting to size, drilling, welding, edge finishing or surface treatment as required).

Finishes & surfaces – from functional to decorative

To ensure that flat bars are not only technically suitable but also visually appealing, FeNau offers various finishes:

• Solid flat steel / structural steel: straightforward, universally applicable, ideal for sturdy basic structures.
• Grooved decorative profiles: e.g. double-grooved flat bars – popular in railing and fencing construction where the appearance remains visible.
• Hammered variants: flat bars with hammered edges for an ‘antique’-style, handcrafted look.
• Textured profiles: corrugated designs or decorative flat bars with a riveted finish as a design upgrade for classic metalwork.
• Wide flat steel: larger cross-sections (e.g. 60×8) for applications where greater material thickness or contact area is required.

Dimensions & lengths – tailored to planning in fencing and metalwork

The range includes standard cross-sections such as 30×6, 30×8 or 40×8, as well as decorative variants (e.g. grooved, corrugated or hammered). Many items are available in practical bar lengths, often 3000 mm – with some variants also available in longer lengths (e.g. 3300 mm for hammered edges). This allows you to plan balustrade panels, gate frames or fence elements efficiently and construct them in a manner appropriate to the material.

Practical tips for selection

• For load-bearing applications: choose solid, smooth flat steel or suitable material thicknesses for frames, crossbars and reinforcements.
• For visible areas: use grooved, hammered or textured profiles – this creates a higher-quality appearance and emphasises the wrought-iron character.
• For a classic look on the fence: decorative profiles (e.g. rivet-effect) add an artisanal touch without complicating the construction.
