Direct factory supply of electroforged, stainless steel, and composite walk surfaces optimized for Central European structural criteria, automated material handling, and aggressive plant logistics.
Technical compliance, structural calculations, and mechanical specifications designed for Slovakia's advanced manufacturing clusters across Bratislava, Trnava, Nitra, Žilina, and Košice.
Slovakia is the world's highest per-capita automobile producer. Plants operated by Volkswagen, Stellantis, Kia, Jaguar Land Rover, and the upcoming Volvo EV facility demand overhead maintenance catwalks that integrate seamlessly with conveyor carriers, robotic cells, and paint shops. Our electroforged gratings feature square twisted cross bars forge-fused under 2200 A current, delivering an ultra-rigid surface with no mechanical flexing under continuous personnel travel.
Facilities like Slovnaft in Bratislava and U. S. Steel Košice expose structural walkways to sulfurous vapor, atmospheric moisture, cyclic thermal loading, and chemical splash. We supply heavy acid-resistant AISI 316 and 316L stainless steel gratings with uniform electropolishing, alongside structural carbon steel hot-dip galvanized per EN ISO 1461 with local coatings exceeding 85 microns to guarantee corrosion resistance in aggressive C3 to C5 industrial atmospheres.
The rise of automated multi-tier logistics hubs along the D1 and D2 motorway corridors requires high-density mezzanine floor platforms. Our light-weighting engineering reduces total deadweight on structural building columns while ensuring concentrated load compliance (5.0 kN point load per EN 1991-1-1). Panels feature precision perimeter banding and welded kick plates (100 mm height minimum per STN EN ISO 14122-3) to eliminate object drop hazards above robotic picking zones.

Operating dedicated electroforging production lines, computerized custom profiling, and rigorous QA frameworks certified to international industrial standards.
Our plant utilizes heavy-duty PLC-automated electroforging presses. By applying over 100 metric tonnes of hydraulic pressure simultaneously with approximately 2200 amperes of electrical current, the twisted cross-bars are fused homogeneously into pre-slotted bearing bars without filler metal. This creates monolithic structural joints completely free of weld inclusions, micro-cracks, and localized structural weak spots.
No industrial catwalk installation is a flat rectangular grid. Structural columns, vertical pipe risers, ductwork, and structural bracing require exact penetrations. We fabricate custom-cut panels from your CAD structural drawings (Tekla, AutoCAD, Revit). Every single curved, circular, or rectangular cut-out is perimeter-banded with matching flat steel bar, preserving structural moment transfer and meeting Eurocode occupational toe-guard rules.
Supplying the Slovak and European Union single market requires uncompromised structural verification. Every production heat is traceable to certified raw material coils with 3.1 Mill Test Certificates per EN 10204. Our manufacturing execution systems conform strictly to EN 1090-2 (Execution Class EXC2 and EXC3), allowing European main contractors to issue their Declaration of Performance (DoP) without regulatory delay.
Strategic structural shifts shaping how general contractors and project managers specify grating packages.
Driven by strict workplace accident prevention standards across modern manufacturing facilities, Slovak safety auditors now strictly mandate compliance with EN ISO 14122-2 Section 4.2.4.4. Catwalks situated above permanently occupied workstations or active traffic routes must prevent the passage of a 20 mm sphere. Specifying 34.3 × 24 mm or 33 × 11 mm mesh configurations is rapidly superseding older, wider open grids.
Contractors operating around Bratislava and Eastern industrial parks increasingly rely on detailed BIM workflows. Rather than manual field cuts—which damage zinc protection layers and initiate premature red-rust corrosion—engineering packages now demand pre-numbered, tag-coded panels manufactured precisely to length with factory-welded banding, significantly cutting onsite mechanical erection schedules.
With environmental lifecycle assessments becoming standard under EU sustainability directives, procurement teams evaluate lifecycle cost over initial purchase rate. Specifying higher yield S355JR structural steel allows reduced bearing bar dimensions without compromising span load capacities, cutting freight emissions, total steel consumption, and galvanizing bath weight.
Direct answers to questions commonly raised by Slovak mechanical contractors, structural detailers, and project procurement departments.
Catwalk and platform gratings installed in Slovakia must conform to harmonized European structural safety norms. Primary regulations include STN EN ISO 14122-2 (working platforms and walkways), STN EN ISO 14122-3 (stairs, stepladders, and guard-rails), and EN 1090-2 for structural steel fabrication. Furthermore, surface protection must strictly satisfy STN EN ISO 1461 for hot-dip galvanizing quality and thickness.
Under EN ISO 14122-2 Section 4.2.4.4, if a catwalk is located above places where people pass or work, the floor must not permit the passage of a ball with a diameter of 20 mm or greater. To meet this standard, we manufacture panels with transverse cross-bar spacing reduced to 24 mm (such as bearing pitch 34.3 mm × cross pitch 24 mm), or utilize dense mesh variants with intermediate safety transverse bars.
Electroforged gratings fuse the bearing bar and cross bar simultaneously through heavy hydraulic tonnage and high-amperage resistance without additional weld filler metal, creating a monolithic, crack-free connection with superior torsional stiffness. Manual press-welded or fillet-welded gratings are typically reserved for specialized custom geometric frames, odd-angle cutouts, or non-ferrous alloys where automated machine tooling cannot be deployed.
For chemical units and paint shop lines exposed to aggressive degreasers, phosphate solutions, and acids, we offer AISI 304, AISI 316, and AISI 316L stainless steel gratings that undergo full acid bath pickling and electrochemical polishing. For standard exterior and platform environments, structural carbon steel is hot-dip galvanized per EN ISO 1461 with local coating thicknesses exceeding 85 μm, guaranteeing multi-decade maintenance-free operational life.
Yes. We fabricate panels directly from your structural drawings. All cut-outs (straight, diagonal, or circular) are reinforced with welded banding bars of the same height as the bearing bars. Furthermore, toe plates (kick plates) measuring at least 100 mm in height can be factory-welded directly to the cut-out edges to satisfy Slovak workplace accident prevention mandates.
