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.

Church steel windows deliver spiritually resonant aesthetics through engineered solutions for ecclesiastical architecture. These steel fenestration systems balance centuries-old visual language with 21st-century performance demands, supporting arched configurations up to 14m height while preserving authentic leaded glass proportions. Unlike concrete or aluminum alternatives, Church steel windows provide non-invasive installation in fragile stone masonry, utilizing custom expansion anchors that distribute structural loads across 8:1 load-bearing ratios.

Technical innovations validated by:

• Material resilience – Hot-dip galvanized steel substrates meet ISO 1461 standards (85µm coating thickness), resisting humidity-induced corrosion in baptismal chapels for 70+ years

• Spectral transmission – Antique glass options replicate pre-1900 light diffusion (92+ CRI) while blocking 99% UV radiation to protect liturgical artifacts

• Seismic compliance – Flex-joint mullions absorb 0.4g lateral acceleration forces, certified to EN 1998-1 for earthquake zones

Notre Dame de Paris restoration specialists specify Church steel windows for their compatibility with medieval construction tolerances (±12mm adjustment range). At Salisbury Cathedral’s 2022 retrofit, these steel windows maintained original stained glass dimensions while upgrading to 0.8 U-value glazing – reducing annual heating costs by £18,000. Maintenance protocols involve simple biannual hinge lubrication, outperforming wood frames needing quarterly repointing.

Documented capabilities:

• Maximum spire height: 16.5m (wind load tested to EN 12211 Class C5)

• Vibration dampening: ≤0.02mm displacement at 110Hz organ frequencies

• 90-minute fire rating (BS 476-22) without intumescent seals

•  ADA-compliant sills at 635mm height
