Engineered to Elevate Commercial, Residential, and Hospitality Bathing Spaces Globally
Solidifying trust through quantitative output and rigorous quality parameters
A comprehensive analysis of structural dynamics, supply chain integrity, and localized compliance systems
Modern residential and commercial architecture increasingly favors modular, light-optimized, and aesthetically minimal design schemas. Within this paradigm, the shower door has evolved from a basic barrier into a structural and design focal point. Frameless glass systems, sliding configurations using architectural-grade rollers, and black-grid designs are reshaping contemporary interiors.
At Hangzhou Kaifeng Sanitary Ware Co., Ltd., established in 2005, we have spent two decades engineering solutions that integrate these visual trends with rigorous mechanical safety. With an annual capacity that includes over 36,000 freestanding bathtubs, 6,000 massage bathtubs, 60,000 shower rooms, and 12,000 integrated cabins, Kaifeng represents a modern manufacturer operating at the intersection of scale, tech, and design.
China's dominance in the sanitary hardware export market is driven by complete industrial clusters, raw material accessibility, and specialized technical expertise. Located in Hangzhou's Xiaoshan District, Kaifeng utilizes a 20,000-square-meter modern production facility to optimize every step of production.
Our monthly output is engineered for high-volume demand, reliably producing:
This high production volume allows us to export over 80% of our products directly to demanding markets such as the USA, Canada, the UK, Germany, South America, and the Middle East. It ensures competitive pricing, optimized lead times, and reliable quality control.
To consistently supply materials to projects globally, products must align with local building codes, safety metrics, and structural requirements. Hangzhou Kaifeng operates under the strict ISO 9001:2000 quality management system. Below are the design specifications built into every shower door model we manufacture:
Tempered safety glass meets SGCC (North America) and CE EN 12150-1 (Europe) approvals. Glass thicknesses span 6mm, 8mm, 10mm, and 12mm options, featuring anti-shatter explosion-proof membranes.
Using 6463-T5/T6 architectural-grade aluminum alloy profiles, featuring anodized or electroplated finishes (black matte, brushed nickel, gold) that resist salt spray testing up to 48 hours.
Optional dual-sided Easy-Clean nano-coatings provide high water-repellent properties, reducing scale buildup, mineral stains, and cleaning frequency by up to 90%.
Every piece of hardware, from brass hinges to stainless steel rollers, is cycle-tested to ensure at least 100,000 smooth openings and closings. This engineering focus eliminates hardware sagging, alignment issues, and water leakage, which are common challenges with lower-quality sanitaryware.
Our factory features advanced production lines, automated glass-cutting machinery, and clean assembly zones. We maintain complete transparency in our production steps and invite global buyers to explore our production floor:
For global distributors, building developers, and hotel chains, finding a reliable supplier is crucial for project success. Kaifeng has built a robust supply chain to support the business needs of international buyers:



Building projects and plumbing distribution channels require verified certifications. Hangzhou Kaifeng Sanitary Ware holds complete certifications to ensure smooth customs clearance and compliance with local building regulations:





Expert insights regarding procurement, customization, and quality assurance
We use high-tensile, tempered safety glass that meets European CE (EN 12150) and North American SGCC standards. Thicknesses range from 6mm to 12mm. For extra safety, we can apply an optional PVB/EVA explosion-proof film or a double-sided water-repellent nano-coating.
For standard OEM models, the typical lead time is 25 to 30 days after receiving the deposit. Custom ODM orders requiring prototype development, custom-extruded aluminum shapes, or specific hardware molds may take an additional 15 to 20 days.
Yes, customization is one of our key strengths. We regularly work with architects and contractors to supply custom sizes, specific glass patterns, and specialized hardware finishes like matte black, brushed nickel, and polished gold.
Every production batch undergoes strict quality checks under our ISO 9001:2000 system, including glass fragmentation tests, structural testing of dynamic hardware, and salt spray testing. For shipping, we use heavy-duty export packaging with thick foam protection and optional solid wooden crates to ensure secure transit.
