Why Choose Export Steel Windows?
Export steel windows redefine structural resilience and design elegance. Unlike aluminum or PVC counterparts, architectural steel windows offer superior load-bearing capacity, enabling slimmer sightlines and larger glass expanses without compromising stability. Commercial steel windows are engineered for high-rise buildings and harsh environments, featuring reinforced corners and multi-point locking systems that exceed ISO security benchmarks. All export-quality steel windows undergo accelerated salt-spray testing (ASTM B117) to ensure zero rust penetration, making steel frame windows ideal for tropical or industrial zones.

Technical Excellence & Customization
Every custom steel window is fabricated using:

• Material: 1.5–2.5mm cold-rolled steel (ASTM A1008) with Class II zinc phosphate coating.

• Surface Treatment: 3-stage powder coating (80μm thickness) in 200+ RAL colors, achieving >2,000 hours QUV weathering resistance.

• Glazing Options: Laminated, tempered, or Low-E glass with argon/krypton fills for U-values down to 0.8 W/m²K.

• Hardware: Marine-grade stainless steel friction hinges and shootbolts (EN 1670:2007 Grade 4) for silent, smooth operation.

Industrial steel windows support spans up to 3.5m without intermediate mullions, while steel sash windows can be configured as tilt-turn, fixed, or sliding units.

Applications & Compliance
From luxury residences to UNESCO heritage restorations, export steel windows deliver:

• Fire Safety: Achieve EI 60–120 fire ratings (BS 476-22) when paired with ceramic glass.

• Acoustic Control: Reduce noise by 45dB (tested per ISO 10140) for airports or urban high-rises.

• Sustainability: 100% recyclable steel with 70% recycled content and thermal breaks to minimize condensation.

Global Export Readiness
All high-performance steel windows are crated in foam-sealed wooden cases with corner protectors, pre-assembled to reduce on-site labor. Documentation includes:

• Mill test certificates (EN 10204 3.1)

• Installation manuals with BIM/Revit files

• CE marking (EN 14351-1) and AAMA 2605 compliance
