Arch Top Single Hung Window

We developed our Arch Top Single Hung Window to provide luxury residential developers and custom home builders with a classic, elegant architectural feature that offers reliable vertical ventilation. Operating from our advanced 30,000-square-meter facility, we use high-tensile 6063-T5 extruded aluminum profiles that are precision-bent to create a perfect, seamless arch head. In high-end custom home designs, arched and geometric windows are highly valued for their aesthetic appeal, but they must also provide excellent energy efficiency and structural stability. This is why our Arch Top Single Hung Window features a fixed top arch sash integrated with a sliding bottom sash that operates smoothly on a constant-force spring balance. This design provides both the elegant look of a traditional arched window and the practical benefits of a vertical slider. The frame is sealed with high-density EPDM weather seals that prevent air and water leaks, ensuring excellent weather resistance. Our focus on premium craftsmanship has made us a trusted partner for major developers and global importers.

We understand that B2B distributors and contractors require high-end custom windows that are built to exact tolerances to ensure smooth installation. The frame of our Arch Top Single Hung Window is manufactured using our advanced CNC precision bending and cutting equipment to ensure perfect structural alignment and squareness. Each window is fitted with high-quality sweep locks and integrated lift rails that make opening and closing the window easy and secure. Our factory has invested over 41 million RMB in advanced CNC machinery and quality testing platforms to ensure every custom unit meets precise specifications. As an ISO9001-certified manufacturer, we conduct a 100% pre-packing inspection on every single window, checking the arch radius, balance tension, and lock alignment. This careful quality check ensures that every window arrives on-site ready to install, saving you time and reducing labor costs. Backed by our structured PDCA quality management system, we guarantee reliable on-time delivery for our monthly capacity of 20 shipping containers, helping you meet your project deadlines with confidence.

Ideally suited for luxury custom villas, traditional estate homes, historic hotel renovations, and premium commercial offices where a classic, upscale arched aesthetic is required.

We specialize in custom manufacturing tailored to your exact architectural drawings and specifications. We can customize the arch radius, frame dimensions, glass configurations (such as decorative arched grids or tinted glass), and frame colors (RAL classic spectrum). Our design team can develop custom samples in 15 to 20 working days, and we provide free sample components to qualified commercial buyers for project approvals.

Every window undergoes a rigorous 100% manual and mechanical inspection before it is packed and shipped. Our manufacturing processes comply with local environmental laws and hold European E0-class environmental certification. If any product is damaged during transit, we handle it quickly through our clear service protocol: immediate responsibility determination, on-site assessment, and priority shipping of replacement parts.
