China Tilt and Turn PVC-steel Composite Windows Manufacturer, Supplier, Factory

When selecting high-performance fenestration for modern architecture, the integration of durable materials and intelligent design is paramount. Our range of Steel Reinforced PVC Composite Windows exemplifies this philosophy, combining the thermal efficiency of PVC with the structural integrity of galvanized steel cores. This hybrid construction allows for larger sash dimensions without compromising stability, making these units ideal for both new builds and renovation projects. For homeowners seeking enhanced security and energy savings, our Residential PVC-steel Composite Windows offer multi-point locking mechanisms and triple weather-stripping to eliminate drafts. In parallel, our Commercial PVC-steel Composite Windows are engineered to meet the rigorous demands of office towers and public facilities, featuring reinforced corner welds and impact-resistant glazing options. The latest generation of Steel Lined PVC Composite Windows also incorporates continuous internal steel linings that further improve mechanical strength and allow efficient tilt-and-turn functionality, enabling easy cleaning and controlled ventilation while preserving a slim sightline.
Tilt and Turn PVC-steel Composite Windows deliver a versatile opening system that adapts to diverse living and working environments. The mechanism allows the sash to tilt inwards at the top for secure, weather-protected ventilation, or swing open fully from the side for maximum egress and cleaning convenience. The frame is manufactured from high-impact uPVC profiles with a fully welded, closed-cell structure, internally reinforced with 1.5 mm to 2.0 mm galvanized steel sections. Glazing beads are co-extruded and double-sealed, accommodating double or triple insulated glass units up to 44 mm thick. Hardware is sourced from premium European suppliers, tested to exceed 20,000 open/close cycles. The finish is a low-maintenance, UV-stabilized foil laminate available in over 20 standard RAL colors, including woodgrain effects, to complement any architectural style.
