At the core of the Olympic Sports sector in Xi'an Chanba International Port Area, China Resources Land has developed a landmark project – Gangchen Runfu. The project is adjacent to the Lugang Campus of Gaoxin No.1 Middle School, with supporting facilities covering education, commerce, healthcare, ecology, and sports & culture. Covering approximately 237.37 mu (about 15.8 hectares) with a total floor area of about 540,617.5 m² and a greening rate of 35%, the project leverages its 237 mu site to create low density, comfortable fourth generation large flat premium residences with a plot ratio of approximately 2.5.
The core of fourth generation residences lies in "sky gardens + large balconies + large area transparent doors and windows" – courtyards that can host plants, balconies wide enough, and living rooms that dare to use large glass panels. However, the more such "transparent" designs are pursued, the more demanding the requirements become for door and window hardware in terms of load bearing, sealing, safety, and durability.
To meet the project's high standards for aesthetics and safety, 3H Building Hardware supplied two hardware systems: the inward opening casement window gap ventilation hardware system and the narrow track lift and slide door hardware system.
Inward‑opening Casement Window Gap‑Ventilation Hardware System
Aesthetics and Sealing: Concealed load‑bearing components ensure a neat appearance and excellent sealing performance.
High Durability and Load Capacity: Hinges have passed over 30,000 opening/closing cycles, with a maximum load capacity of 60 kg, offering robust and long‑lasting performance.
Safe Ventilation: A 90° handle operation enables gap ventilation; in the restricted position, continuous air exchange is maintained, resolving the conflict between stuffy rooms with closed windows and unsafe conditions when windows are fully opened.
Narrow‑Track Lift‑and‑Slide Door Hardware System
Superior Load Capacity: Heavy‑duty rollers can bear up to 300 kg per leaf, perfectly suited for heavy lift‑and‑slide doors.
Flexible Operation: With a 0° lift‑to‑open and 180° lower‑to‑lock handle mechanism, lifting the handle locks the door in position, allowing free adjustment of the opening area.
Open and Airy Design: Enables expansive balcony views and a strong sense of spatial openness.
Stable and Safe: Patented integrated anti‑derailment and anti‑swing design, combined with high‑strength stainless steel precision‑cast locking points and keepers, effectively resists severe weather conditions.
With its systematic product solutions, 3H Building Hardware provides reliable support for the critical nodes of fourth‑generation residences. This not only ensures the realisation of design highlights such as "sky gardens" and "large‑scale balconies" but also delivers a tangible improvement in the living experience for homeowners.
Looking ahead, 3H Building Hardware will continue to focus on product R&D and quality control, partnering with more quality real‑estate developers to jointly drive the ongoing evolution of residential product excellence.
