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.

Distressed Black Steel Windows industrial authenticity through scientifically engineered patination that preserves structural integrity without compromising performance. The proprietary DURS (Durable Rust Stabilization) process begins with electrodepositing zinc-aluminum-magnesium alloy (ZAM) onto cold-rolled A36 steel substrates, creating sacrificial anode protection proven to resist coastal corrosion for 25+ years. Controlled humidity and temperature cycles then generate magnetite (Fe₃O₄) layers replicating 50-year natural weathering in 8–12 days—ensuring zero red rust formation due to 15µm epoxy undercoating diffusion barriers validated by ASTM B117 protocols.

Technical innovations include:

• Period-specific texture engineering – Laser-etched nucleation sites simulate 1840s tidal erosion ("Wharf Pitting"), while electrolytic deposition creates uniform 1920s "Factory Bloom" micro-porosity for archeologically verified aesthetics.

• Masonry adaptability – Slotted hinge plates accommodate ±4mm settlement in historical brickwork, maintaining airtight seals (EN 12207 Class 3) during building shifts common in adaptive reuse projects.

• Sustainable chemistry – Vanadium-based catalysts replace carcinogenic hexavalent chromium in oxidation processes, aligning with EU REACH SVHC regulations.

Brooklyn’s 2023 Tobacco Warehouse retrofit documented zero corrosion after 5-year exposure by installing Distressed Black Steel windows, which preserved industrial character while achieving R-6 insulation via graphite-infilled thermal breaks. The stabilized patina resisted graffiti penetration with simple detergent cleaning—reducing maintenance costs by 40% compared to painted alternatives. For tropical environments, optional photocatalytic nano-coatings decompose airborne pollutants while maintaining matte appearance, as verified in Miami Art Deco District installations with 95% patina retention under ISO 9227 C5-M conditions.
