1.5mm Galvanized Steel Cores Eliminating Long-Term Sash Drooping
Load-bearing hinges anchor directly into internal steel ribs, supporting 80kg sashes without sagging or frame scraping.
Engineered for coastal high-rises, our steel-reinforced UPVC casement windows combine 1.5mm galvanized cores and multi-chamber walls for extreme wind resistance and low U-values.
Load-bearing hinges anchor directly into internal steel ribs, supporting 80kg sashes without sagging or frame scraping.
Multi-cell polymer barriers interrupt conductive paths, optimizing HVAC performance and stopping winter frame condensation.
Continuous dual perimeter seals compress under multi-point locking cams, eliminating air drafts and blocking ambient fine dust.
Lock tracks and weep holes are CNC-machined to ±0.5mm tolerances, halving jobsite installation labor without errors.
