Manufactured on high-speed CNC continuous roll-forming lines using premium hot-dip galvanized steel coils (Z100–Z275 g/m²). Directly engineered to meet European building standards (EN 14195, EN 10346, Eurocode 3, and Eurocode 8).
A rigorous engineering evaluation of cold-formed galvanized steel battens, hat profiles (Omega channels), and light-gauge furring assemblies operating under Bulgarian Institute for Standardization (БИС) and Eurocode criteria.
Our galvanized battens are manufactured exclusively from certified structural steel grades DX51D+Z, DX52D, and high-tensile S250GD/S320GD. In compliance with European Standard EN 10346, the protective zinc mass ranges from standard Z140 (140 g/m² total double-sided mass) up to marine-grade Z275 (275 g/m² ~ 20 µm nominal thickness per face).
For Bulgarian regions prone to atmospheric moisture, such as the coastal zones of Burgas and Varna, or heavy industrial perimeters around Plovdiv and Devnya, our factory provides passivated, chemically oiled, or Galfan (95% Zn, 5% Al) metallurgical treatments that eliminate white rust formation during maritime container transit and wet on-site laydown periods.
Bulgaria features some of the highest seismic vulnerability zones within the European Union, categorized under Bulgarian National Annex to BDS EN 1998-1 (Eurocode 8) with peak ground acceleration (PGA) reference values ranging from $a_g = 0.16g$ up to $a_g = 0.32g$ across Sofia, Struma, Maritsa, and Shabla seismic fault areas.
Timber laths traditionally used in roof and ceiling substructures exhibit brittle failure and hygroscopic dimensional instability under lateral cyclic earthquake loads. Our cold-formed galvanized hat profiles and CD/UD channel systems deliver consistent ductility, engineered moment of inertia, and predictable screw-withdrawal pull-out values, preserving architectural envelope integrity without secondary structural collapse.
Under Bulgarian National Fire Safety Ordinance No. Iza-1971 (Наредба № Iз-1971 за строително-технически правила и норми за осигуряване на безопасност при пожар), light steel battens and drywall profiles must achieve Class A1 reaction to fire without contribution to toxic smoke emission (s1) or flaming droplets (d0). Our cold-formed profiles are completely non-combustible, eliminating the thermal decomposition hazards associated with preservative-treated timber furring.
| Profile Designation | Material Grade (EN 10346) | Standard Thickness (mm) | Zinc Coating (g/m²) | Yield Strength ($R_e$, MPa) | Bulgarian Application Scope |
|---|---|---|---|---|---|
| Hat Batten (Omega 22/40) | DX51D+Z / S280GD | 0.50 – 0.80 mm | Z140 – Z275 | ≥ 280 MPa | Pitched metal roofing, ceramic tile substructures, rainscreens |
| Ceiling Channel CD 60/27 | DX51D+Z | 0.50 – 0.60 mm | Z100 – Z200 | ≥ 220 MPa | Acoustic suspended ceilings, fire-rated ceiling membranes |
| Perimeter Track UD 28/27 | DX51D+Z | 0.50 – 0.60 mm | Z100 – Z200 | ≥ 220 MPa | Wall perimeter boundary anchor for CD ceiling assemblies |
| Furring Channel (22mm Deep) | DX51D+Z / S250GD | 0.55 – 1.00 mm | Z140 – Z275 | ≥ 250 MPa | Internal masonry drylining, basement wall thermal upgrades |
| Heavy Facade Batten (Omega 40/60) | S320GD+Z | 0.80 – 1.50 mm | Z275 | ≥ 320 MPa | Exterior ventilated facade cladding, high wind-load zones |
From European Union thermal retrofit initiatives in Sofia to high-throughput logistics hubs in Plovdiv and coastal developments in Varna and Burgas, our profiles deliver decisive structural advantages.
Under the Bulgarian National Recovery and Resilience Plan (NRRP), extensive renovation targets socialist-era prefabricated panel residential complexes (panelki). Replacing decayed wooden substructures with non-combustible galvanized steel furring battens ensures a permanent, unyielding mounting plane for rigid mineral wool insulation and ventilated fiber-cement facade panels.
The industrial surge across Plovdiv (Maritsa Economic Zone), Bozhurishte, and Elin Pelin demands rapid-assembly secondary structural envelopes. Our heavy-gauge galvanized roof battens and wall furring channels interface seamlessly with structural steel frames, supporting metal sandwich panels, acoustic interior cladding, and profiled roof decks with zero warping.
Hotel resorts and residential villas situated in Sunny Beach, Nesebar, Varna, and Golden Sands encounter high airborne saline concentrations. Traditional galvanized channels with substandard coatings quickly suffer galvanic pitting. Our specialized Z275 hot-dip profiles provide superior electrolytic shielding, ensuring lifetime rust immunity under ISO 12944 C3/C4 environments.
Commercial airports, metro terminals (Sofia Metro Line extensions), hospitals, and shopping centers demand suspended ceiling sub-frames certified under EN 13964. Our knurled CD 60/27 profiles and reinforced primary channel carriers withstand dynamic ceiling accelerations during seismic events, preventing ceiling grid dislodgement while maintaining acoustic absorption baffles.
Alpine microclimates in Bulgaria's Rila, Pirin, and Rhodope mountains subject pitched roofs to severe snow accumulation loads (up to 2.5 kN/m² under BDS EN 1991-1-3) and extreme freeze-thaw condensation cycles. Our steel roof battens eliminate water absorption, preventing ice-dam rot, nail withdrawal, and fungal deterioration beneath standing seam metal and clay tile covers.
Operating high-speed multi-stage cold roll-forming lines, automated decoiling, precision punching, and inline dimensional tolerance lasers since 2009.
Every batch of prime raw material is inspected with 3.1 Mill Test Certificates (MTC) verifying chemical composition, elongation, and yield strength according to EN 10204.
Continuous diamond-knurling embossing applied during roll-forming prevents self-drilling drywall screw slippage, increasing contractor screw-driving speed by over 30% on job sites.
High-precision multi-pass forming rollers prevent camber, bow, and cross-sectional twisting across standard lengths (3000mm, 4000mm) and custom cut-to-length project runs.
Profiles are strapped in rigid bundles, wrapped in moisture-barrier plastic film, and stabilized on heavy timber runners to withstand multi-modal sea freight to Port Varna and Port Burgas.
