Extended Length Sliding Hinge
,16 Inch 304 Sliding Hinge
,Large Window Sliding Hinge
16-inch, 22-slot, 3.0mm-thick 304 Stainless Steel Heavy-Duty Four-Link Sliding Hinge
This product is an extended-length, heavy-duty load-bearing sliding hinge specifically designed for extra-large casement windows. It is precision-stamped from 3.0mm-thick 304 stainless steel sheet, Its 16-inch extra-long arm is designed to fit standard 22mm door and window profile grooves. The four-link mechanism offers high load-bearing capacity and a wide opening range, along with excellent corrosion and rust resistance, making it the core load-bearing hardware component for oversized thermal break aluminum floor-to-ceiling windows and heavy-duty outward-opening windows.
Thickened 304 Stainless Steel Base Material, Outstanding Heavy-Duty Corrosion Resistance
The entire hinge is precision-stamped from a single piece of SUS304 stainless steel sheet with a thickness of 3.0 mm, providing robust structural rigidity and load-bearing capacity. It can stably support heavy window sashes of extra-large dimensions and significant weight, withstanding the sash’s own weight and strong wind loads over the long term without bending or deforming, and demonstrating excellent wind and pressure resistance.
304 stainless steel inherently possesses excellent corrosion and rust resistance. Verified through a 500-hour salt spray test, it ensures long-lasting performance in harsh environments such as coastal areas with high humidity, outdoor exposure to sun and rain, and damp conditions in kitchens and bathrooms, without issues like rust, jamming, oxidation, or wear. All hinge points are precision-riveted using solid rivets, ensuring a tight fit with no play and smooth, low-noise operation. The product complies with the QB/T 5338-2018 General Technical Standard for Door and Window Hardware and has passed a 100,000-cycle durability test for repeated opening and closing. It maintains stable performance during frequent, year-round operation and offers a long, reliable service life.
Extra-long four-bar linkage structure provides stable support for wide opening angles
Featuring a 16-inch (approx. 406 mm) extra-long arm design paired with a classic four-bar linkage transmission mechanism, the window sash can open to a wider maximum angle, providing superior ventilation. The opening and closing process distributes force evenly, ensuring a smooth and stable operating trajectory without jamming, wobbling, or shaking. When open, the overall structure forms a stable triangular mechanical support that firmly locks the sash at the desired opening angle, withstanding strong wind impacts and preventing the sash from swaying and colliding with the window frame. It also limits the maximum opening angle, balancing ventilation effectiveness with home safety.
The slider ends are equipped with wear-resistant guide and stop components, ensuring uniform sliding resistance and a smooth, effortless feel when opening and closing. The end stops are reliable and precise, effectively enhancing the smoothness of opening and closing extra-large window sashes and improving the daily user experience.
Standard groove dimensions ensure easy installation and strong compatibility
Compatible with 22mm-wide standard door and window profile grooves, this is a universal specification for oversized thermal-break aluminum casement windows, heavy-duty exterior casement windows, and top-hung windows. The base features industry-standard mounting holes for precise alignment, allowing for quick assembly using standard screws. No additional cutting or grooving of the profiles is required, making batch assembly at door and window factories efficient and time-saving, while also facilitating convenient replacement during home renovation and after-sales maintenance.
Wide Range of Applications
Widely compatible with oversized outward-opening windows, heavy-duty thermal-break aluminum floor-to-ceiling windows, large-format balcony casement windows, and heavy-duty top-hung windows for sunrooms; suitable for residential large-window hardware systems, high-end finishing projects in real estate developments, load-bearing performance upgrades for older windows and doors, as well as bulk export supply of window and door hardware.
