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.

Industrial loft steel windows embody raw materiality through engineered steel framing systems that transform converted factories and urban residences. These steel windows utilize standardized modular grids (e.g., 3x6 or 4x8 divided lites) to create rhythmically transparent partitions between living and workspace zones, with black RAL 9011 frames providing industrial aesthetics that increase property values by up to 18% according to New York loft market surveys. Unlike aluminum alternatives, Industrial loft steel windows maintain dimensional stability across -30°C to 80°C ranges – critical for climate-controlled art galleries or humid kitchens – through micro-welded joints with 0.02mm tolerance.

Documented capabilities:

• Acoustic control – 42dB STC rating when paired with 35mm laminated glass, isolating urban noise in downtown apartments adjacent to elevated transit lines.

• Fire safety – Achieve 60-minute integrity ratings (BS 476-22) via intumescent graphite seals in mullion cavities, enabling code-compliant egress corridor installations.

• Fabrication precision – Robotic welding and CNC-notched connections ensure ±0.8mm alignment across 12m continuous runs, eliminating onsite shimming during historical warehouse conversions.

Toronto’s Distillery District retrofit utilized Industrial loft steel windows to preserve cast-iron column aesthetics while achieving R-5 insulation values through aerogel-infilled thermal breaks. Maintenance requires only annual silicone lubrication of pivot hinges, with electrophoretic deposition (ED) coatings resisting graffiti and industrial pollutants for 25+ years. The system accommodates curved glazing radii down to 800mm for turret installations, supporting 1.5kPa wind loads in coastal high-rises.

Specification guidelines:

• Grid options: Asymmetric, Fibonacci sequence, or custom CAD patterns

• Maximum unit size: 3.2m × 4.5m (structural silicone glazing compatible)

• Water resistance: E331-16 tested at 8.4 PSF without leakage

• Thermal performance: U-value 1.1 W/m²K with triple glazing
