Product Description
10-inch, 22-slot, 3.0mm-thick 304 Stainless Steel Four-Link Hinge
This heavy-duty support hinge is specifically engineered for casement windows requiring exceptional load-bearing capacity. Precision-crafted from 3.0mm-thick 304 stainless steel, it features a 10-inch extended arm compatible with standard 22mm profile slots. The four-link mechanism ensures smooth operation and stable support, offering superior corrosion resistance for large thermal break aluminum windows and heavy-duty outward-opening applications.
Premium Material Construction
Manufactured from a single piece of SUS304 stainless steel with 3.0mm thickness, this hinge delivers enhanced structural rigidity and load-bearing capacity compared to conventional thin-profile alternatives. The material resists bending and deformation under heavy window sash loads while providing excellent wind and pressure resistance.
Certified Durability: Verified through 500-hour salt spray testing, this hinge maintains performance in coastal, outdoor, and high-humidity environments without rusting, jamming, or oxidizing. All hinge points feature precision solid-rivet fastening for tight fit and smooth, low-noise operation.
Compliant with QB/T 5338-2018 technical standards and tested to 100,000-cycle durability, this hinge ensures long-term reliability and extended service life even with frequent use.
Advanced Four-Link Mechanism
The classic four-bar linkage transmission with 10-inch extended arm design provides smooth, stable opening trajectories. Forces distribute evenly during operation, eliminating jamming, wobbling, or shaking.
- Stable triangular support when open, firmly locking sash at desired angles
- Withstands strong wind impacts and prevents sash swaying or frame collision
- Maximum opening angle limitation balances ventilation and safety
- Wear-resistant guide and stop components ensure smooth operation
