Solid Brass Sash Lifting Window is a vertically sliding window system manufactured from solid brass. It's suitable for villas, heritage buildings, apartments, and renovation projects where durability and premium finishes are essential.
Unique material advantages:
Solid brass VS market imitations
| Characteristics | Our materials | Defects of "imitation copper" on the market |
| Composition | C27200 copper-zinc alloy (copper 62-65%) | Copper-plated iron parts (copper layer <0.1mm) |
| Corrosion resistance | No discoloration in 5000h salt spray test (ASTM B117) | Plating peeled off in 6 months (C3 environment) |
| Mechanical strength | Tensile strength ≥380MPa (cold forging strengthening) | Die-cast zinc alloy ≤200MPa |
| Life cycle cost | 50 years maintenance-free (measured Cambridge University project) | 5 years replacement + 3 maintenance |
features
Durable Construction
Manufactured from high-grade solid brass for superior strength, corrosion resistance, and long service life.
Effortless & Quiet Operation
Precision hardware and balanced structure reduce friction and vibration, ensuring smooth and low-noise (≤25dB) vertical movement.
High Thermal Conductivity
Utilizing C27200 brass with thermal conductivity up to 110 W/m·K, effectively dissipates heat and minimizes thermal stress on the glass, reducing the risk of cracking.
| Risk | Technical solution |
| Window sash falling | Brass escapement rack + self-locking ratchet (automatic locking on overload) |
| Hardware theft | Bidirectional non-standard screws (special tools required for removal) |
| Sudden strong wind | Air pressure induction braking (wind speed＞15m/s self-locking) |
