Explore our premium architectural structures and luxury sanitary collections engineered for global developers and B2B buyers.
From a dedicated design workshop in 2005 to an international supply leader, Hangzhou Kaifeng Sanitary Ware Co., Ltd. delivers high-precision architectural solutions.
Established in 2005, Hangzhou Kaifeng Sanitary Ware Co., Ltd. has evolved into a key player in the sanitary and glass door manufacturing sectors. Strategically located in Hangzhou's Xiaoshan District, our state-of-the-art production facilities run under the stringent ISO 9001:2000 Quality Management System. This ensures that every frameless glass panel, hardware bracket, and finished shower enclosure complies with international structural benchmarks.
Currently, our annual output includes over 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 premium shower enclosures, and 12,000 custom sanitary components. With annual sales revenues exceeding USD 10,000,000, more than 80% of our products are shipped to high-compliance markets, including the USA, Canada, the United Kingdom, Germany, South America, and the Middle East.
Modern architectural trends increasingly rely on minimalist design profiles. The shift from heavy, framed configurations to frameless systems is not merely an aesthetic choice; it represents a major advancement in structural engineering. By utilizing the inherent strength of tempered and laminated safety glass, developers can achieve uninterrupted fields of view while maintaining load-bearing properties.
From a structural perspective, a cheap frameless glass door does not imply sub-par quality. Instead, it indicates an optimized manufacturing workflow where cost reduction is achieved through scale, automated CNC edge-polishing, and standardized hardware preparation. By focusing on raw material quality—specifically low-iron silica sand and premium polyvinyl butyral (PVB) interlayer films—our factory balances affordability with mechanical performance.
Our panels undergo thermal toughening processes that increase flexural strength by 4 to 5 times compared to standard float glass, meeting EN 12150 and ANSI Z97.1 certification criteria.
Optional nanotech polymer coatings create a highly hydrophobic surface shield that repels soap scum, mineral deposits, and water staining, drastically lowering lifetime maintenance costs.
We source corrosion-resistant SUS304 and SUS316 stainless steel brackets and hinges, tested for up to 100,000 cycles without structural fatigue or alignment slippage.
The international supply chain for frameless glazing systems has shifted towards structured OEM and ODM relationships. Commercial developers in North America and Western Europe require high-volume deliveries of standardized sizes alongside small batches of bespoke cut-to-size units. As a high-capacity factory, we balance these requirements by operating both automated production lines for standard panels (8mm and 10mm thicknesses) and custom processing stations.
This dual-track manufacturing capability allows us to support major commercial developments—such as multi-family residential towers in Canada, luxury hotels in the UK, and large-scale office park fit-outs in the Middle East. By reducing production downtime and utilizing optimal container loading configurations, we control transport costs and offer highly competitive pricing models globally.
Transparency is key to establishing trust in global sourcing. Examine our advanced production floors, precision glass cutting stations, and packaging bays.
Our factory spans over 20,000 square meters of space, organized into processing segments: automated CNC cutting, computerized glass edge polishing, high-temperature convection tempering furnace, hardware CNC milling, and comprehensive testing laboratories. Our production capacity reaches 1,500 bathtubs, 1,500 shower enclosures, and 2,000 shower panels monthly, guaranteeing stable supply lead times for international projects.
Navigating localized building codes is a critical factor for international buyers sourcing glass and sanitary products. Our engineering team designs all frameless hardware and glass systems to align with specific regional requirements:
By maintaining these standards, Hangzhou Kaifeng minimizes import and regulatory challenges for global distributors, builders, and wholesalers.
Frameless glass door assemblies are utilized across multiple architectural applications:
We undergo regular external audits to verify compliance across quality management, safety protocols, and supply chains.





As architects and green building councils push for net-zero construction, the glazing industry must adapt. Our engineering division is researching three key technology corridors to integrate into upcoming production cycles:
Our roadmap focuses on keeping Hangzhou Kaifeng sanitary and architectural structures at the forefront of the industry, delivering long-term value to our distribution partners.

For standard sizes, our factory maintains a 20-to-25-day production cycle from technical drawing approval to container loading. For fully customized orders, including specific glass shapes, CNC cutouts for specialty hardware, or custom patterns, lead times average 30 to 35 days.
We package all glass panels using high-density shock-absorbing corner protectors, wrapped in moisture-resistant film, and secured in custom-made L-frame wooden crates or solid plywood boxes. Every container is systematically packed and braced to prevent shifting during maritime transit.
Yes. All glass clamps, hinges, handles, and rollers are manufactured from premium SUS304 or SUS316 stainless steel, or lead-free solid brass. We carry out 48-hour salt spray tests to ensure our finishes remain rust-resistant in highly humid steam environments.
Our internal engineering office supports OEM/ODM development. We accept CAD files, produce technical shop drawings, and run simulation checks to ensure your custom glass thicknesses, structural hardware, and design details comply with local safety requirements.
