Leading the market in precision-engineered zinc alloy and stainless steel fittings.
Established in 2007 (formerly Tiezhu Hardware Factory), Ningbo Huazhu Precision Machinery Co., Ltd. specializes in producing shower enclosure accessories, bathroom fittings, and commercial window stay solutions. With nearly two decades of growth, we have evolved into a full-service manufacturing powerhouse.
Our philosophy is rooted in creating value for customers, achieving win-win partnerships, and empowering our workforce. We manage the entire industrial chain—from mold making to electroplating—ensuring every Commercial Window Stay meets global standards.
We boast a complete industrial chain including:
Addressing the complex needs of modern commercial architecture.
Commercial window stays are critical for high-rise buildings where safety is paramount. Our OEM solutions include integrated limiters that prevent windows from opening beyond a safe angle, reducing fall risks while allowing natural ventilation.
Using high-grade SS304 and Zinc Alloy materials, our hardware is designed to withstand significant wind pressure in coastal or skyscraper environments. Every component undergoes rigorous stress testing to ensure structural integrity.
A precision-fitted window stay ensures a perfect seal when closed, significantly reducing thermal leakage. This contributes to LEED certification and lowers HVAC costs for commercial facility managers.
The global window stay market is shifting toward smarter, more durable hardware. As a top-tier Commercial Window Stay Factory, we leverage China’s unique industrial ecosystem to provide advantages that European or North American facilities often cannot match:
1. Supply Chain Synergy: Based in Ningbo, we have immediate access to raw material markets (Zinc alloy, Stainless steel) and specialized surface treatment clusters, drastically reducing lead times.
2. R&D Agility: Our in-house mold workshop allows us to go from blueprint to prototype in just 28-35 days, a speed essential for modern architectural pivots.
3. Advanced Surface Science: We offer Neutral Salt Spray (NSS) testing options ranging from 240H to 480H, ensuring hardware longevity even in highly corrosive marine climates.
4. Cost-to-Quality Ratio: By integrating die-casting, machining, and assembly under one roof, we eliminate middle-man costs while maintaining strict 100% inspection protocols.
Professional buyers from Germany (Dornbracht), Japan (TOTO), and Italy (INDA) trust our factory because we provide more than just products—we provide technical risk mitigation and compliance reliability.
Get Procurement GuideAdvanced equipment ensuring tolerances within 0.02mm.
Our factory is equipped with several hot and cold die-casting machines and precision machinery. The processing accuracy can reach 0.02mm, which guarantees the high quality of our commercial hardware. With automatic polishing machines and a large number of professional workers, we ensure both the aesthetic finish and the structural durability of every window stay produced.
From our inception in Ningbo, Zhejiang, in 2007, we have remained committed to one goal: Realize the dream for employees and create value for customers. Today, we are a comprehensive enterprise integrating R&D, sales, and manufacturing for domestic and international clients, winning consistent praise for our technical service.
Commercial window stays tailored for specific architectural environments.
Smooth, silent operation is essential. Our stays are engineered with friction adjusters to maintain positions effortlessly while providing a premium hand-feel for guests.
Heavy-duty restrictor stays ensure patient safety while allowing essential fresh air circulation. Our stainless steel alloys offer superior resistance to harsh medical cleaning agents.
Durability for high-traffic use. Our hardware is tested for over 50,000 opening cycles to survive the rigorous demands of school and university environments.
