Roll-formed door and window frames are precision-engineered metal structural profiles manufactured through a continuous cold roll-forming process. Utilizing high-quality steel or aluminum coils, these frames deliver exceptional dimensional accuracy, structural rigidity, and design flexibility for residential, commercial, and industrial building envelope applications，such as Residential sliding windows and casement windows, Commercial curtain walls and storefront systems,Industrial warehouse doors and fire-rated door frames,Security doors and architectural partition frames etc.

Precision Manufacturing: Continuous cold roll-forming ensures consistent profile geometry with tight tolerances (±0.2mm), ideal for high-volume production and seamless integration.
Material Versatility: Available in galvanized steel (GI, GL, Zn-Al-Mg), stainless steel, and aluminum alloys (6063-T5, 6061-T6).
Superior Durability: Enhanced corrosion resistance through hot-dip galvanization, Zn-Mg coating, or powder coating, ensuring a long service life even in harsh environments.
Design Flexibility: Customizable cross-sections (C-shaped, Z-shaped, box sections, multi-cavity designs) to accommodate various glazing thicknesses, thermal breaks, and hardware requirements.
Thermal Efficiency: Optional integrated thermal break designs significantly reduce heat transfer, meeting modern energy-saving building codes (e.g., LEED, Passive House).
Cost-Effectiveness: Optimized material usage and high-speed production lower unit costs compared to traditional extrusion or welding methods.
