LG37S Hot-rolled steel series

Produced with hot-rolling technology, the 37 Series delivers a bold and solid profile with exceptional structural stability. Its clean, powerful lines make it ideal for expansive floor-to-ceiling windows, public architecture, and industrial-style projects, creating a strong visual presence and architectural impact.

LG50S Cold-bent steel series

Formed through advanced cold-bending techniques, the 50 Series is distinguished by its slim and refined profile, combining strength with lightness. It is best suited for interior partitions, fine window divisions, and minimalist modern spaces, offering both stability and a sense of elegance.

LG65S Thermal-break steel series

With integrated thermal-break technology, the 65 Series combines the inherent strength of steel with superior insulation and soundproofing performance. It is particularly suited for villas, luxury residences, and high-performance commercial spaces, ensuring both comfort and long-term durability.

steel-look thermal-break aluminum alloy

Built on lightweight aluminum alloy with thermal-break design, the 65 Steel-look Series replicates the authentic appearance of steel while offering aluminum’s advantages of corrosion resistance, insulation, and reduced weight. Perfect for modern homes, apartments, and design-focused spaces, it balances performance with distinctive aesthetics.

Cafe french windows with seeded glass merge nostalgic aesthetics with hospitality-grade functionality through patented safety glazing technology. The steel-framed folding systems incorporate seeded glass—produced by rolling molten silica over crushed marble to generate organic bubbles—while bonding it to 1.52mm PVB interlayers for impact resistance. Each 6–12mm pane contains 18–35 bubbles/cm² that diffuse direct sunlight, reducing glare by 40% during peak service hours without artificial shading.

Operational enhancements:

• Hygienic thresholds – Triple wiper brushes block 98% airborne particulates (critical for bakeries), with antimicrobial bronze coatings inhibiting pathogen growth

• Ergonomic kinematics – Counterbalanced hinges require <12N operating force despite 85kg leaf weight (EN 12400 Class 4 certified).

  
  

• Security integration – Drill-resistant BHMA A156.23 Grade 1 cylinders deter forced entry during closures.

Parisian café "La Ruelle" reported 17% higher afternoon revenue after installation, attributing success to Instagram-worthy light patterns and reduced HVAC costs. The seeded glass surface trapped 60% less grease than smooth glass, cutting daily cleaning by 25 minutes. Insulated glazing units maintained 0.95 SHGC for passive solar heating, enabling 3-month energy savings in temperate climates. Structural testing confirmed wind load resistance up to 1.5 kPa (EN 12211) and condensation resistance factor (CRF) of 79 per NFRC 500.

Certified performance:

• Light transmission: 92% VLT with astigmatism <0.1 diopters

• Frame construction: 45mm hot-rolled steel with 1.5mm wall thickness

• Thermal performance: U-value 1.3 W/m²K (argon-filled double glazing)

• Durability: 100,000+ operation cycles (EN 12400 Class 4)
